Description
A METHOD OF INSULATING A BUILDING
This invention relates to a method of insulating a building.
It is known to insulate a building to reduce the thermal transmittance through the building. In particular, a cavity present between the outer and inner leafs in a cavity wall of a building can be a source of thermal transmittance, and so it is desirable to provide insulation within the cavity.
According to the first aspect of the invention there is provided a method of insulating a building having multiple elevations each of which elevation has an associated cavity lying there behind, a plurality of first such elevations having at least one aperture formed therein to receive a window element and at least one second such elevation being devoid of window element receiving apertures, the method comprising the steps of: (a) forming in relation to each first elevation respective opposed pairs of openings extending into the associated cavity thereof at each of a low level, a mid level and a high level; (b) forming in relation to the or each second elevation respective opposed pairs of openings extending into the associated cavity thereof at each of a mid level and a high level; and (c) injecting an insulant material into the associated cavity of each elevation via the corresponding opposed pairs of openings in the following order: (i) the low level in each first elevation and the mid level in the or each second elevation, starting in a given elevation and moving to an adjacent elevation around the building; (ii) the mid level in each first elevation, starting in a given first elevation and moving to an adjacent first elevation around the building; and (iii) the high level in each first elevation and the or each second elevation, starting in a given elevation and moving to an adjacent elevation around the building.
Forming an opposed pair of openings that extend into an associated cavity at each of the levels outlined above provides apertures for injecting an insulant material into the associated cavity whilst minimising the number of openings required for such injecting. In this way, the labour associated with forming and subsequently injecting into the openings is reduced when compared to forming a series of openings directly in to the cavity of each elevation formed through the face brickwork at various required levels. Such an approach also has a lower visual impact on the appearance of a building than the aforementioned series of openings.
In addition, forming respective opposed pairs of openings at each of a low level, a mid level and a high level in relation to each first elevation allows for the insulant to be injected at high pressure in a single direction, parallel to the brickwork. This method is therefore less reliant on gravitational forces to aid the spread of the insulation material, and virtually eliminates the risk of a back pressure of air building within the cavity, to prematurely stop the flow of insulation, until such time as the wall has been fully filled up to the level of each pair of openings. This reduces the risk of the insulation of a building being incomplete because the flow of insulant material is otherwise interrupted by the or each window element receiving aperture.
Meanwhile injecting the insulant material in the order outlined above, and in particular in the low level in each first elevation and the mid level in the or each second elevation in turn around a building, (as opposed to injecting the insulation into the cavity through openings formed in the face brickwork, starting with the lowest and in turn at each level upwards on each elevation), results in an even distribution of insulant material throughout the height of and around the building. More particularly, when working around the building at each of the low, mid and high levels there is less chance of the insulation overspilling into an adjacent empty cavity and falling to a lower level which would restrict the flow of insulation material when injection takes place in the adjacent cavity at a lower level.
Optionally, when the method is applied to a building in which at least one first elevation includes a ground floor window element receiving aperture, the step of forming in relation to the or each corresponding first elevation respective opposed pairs of openings at a mid level includes positioning the mid level above the ground floor window element receiving aperture.
In some embodiments of the invention, when the method is applied to a building in which at least one first elevation includes a first floor window element receiving aperture, the step of forming in relation to the or each corresponding first elevation respective opposed pairs of openings at a mid level includes positioning the mid level below the first floor window element receiving aperture.
Meanwhile when the method is applied to a building in which at least one first elevation includes a ground floor window element receiving aperture and a first floor window element receiving aperture, the step of forming in relation to the or each corresponding first elevation respective opposed pairs of openings at a mid level may include positioning the mid level between the ground floor window element receiving aperture and the first floor window element receiving aperture.
Positioning the mid level in each of the aforementioned manners allows each opening to define a pathway for the insulant material and a resulting trajectory path that is not immediately obscured by one or more window element receiving apertures present in the corresponding first elevation. In this way, the insulant material can fill, unhindered, a large area of the associated cavity.
Preferably the step of forming in relation to the or each second elevation respective opposed pairs of openings at a mid level includes positioning the mid level between the low level and the high level in an adjacent first elevation.
Optionally the step of forming in relation to each first elevation and the or each second elevation respective opposed pairs of openings at a high level includes positioning the high level in the corresponding first or second elevation below a ceiling line of the respective elevation, with the ceiling line being determined by a ceiling joist of the building.
Meanwhile, the step of forming in relation to each first elevation respective opposed pairs of openings at a low level may include positioning the low level below the ground floor window element receiving aperture formed in the said first elevation or in another first elevation.
Positioning the low level of each first elevation below the ground floor window element receiving aperture formed in the said first elevation or in another front elevation allows, in instances where the first elevation includes such a ground floor window element receiving aperture, the insulant material to fill an area of the cavity below the ground floor window element receiving aperture which might otherwise be missed by insulant material being injected through the openings at the mid level due to the ground floor window element receiving aperture obstructing the flow of insulant material.
Similarly, in instances where the respective first elevation has no ground floor window element receiving apertures, positioning the low level as aforementioned reduces the risk of the associated cavity not being filled properly by insulant material injected via the openings at the mid level.
Preferably positioning the mid level in the or each second elevation includes positioning the said mid level not more than 2 metres from a support surface on which the building is constructed. In this way, insulant material is injected into the associated cavity at a height not more than 2 metres from the support surface and so the likelihood of parts of the cavity not being filled is much reduced.
Optionally, the steps of forming in relation to each first elevation and the or each second elevation respective opposed pairs of openings extending into the associated cavity thereof includes forming each opening through a face of an adjacent elevation so that the resulting opening lies substantially parallel with the elevation associated with the cavity in question.
Forming each opening arranged in this way desirably provides access to the cavity in question in a manner that permits the spraying of insulant material with high pressure from each pair of openings in a single direction, parallel to and directly behind the outer brickwork and across a large unrestricted area of the cavity which obviates the need for other openings to be formed which, in turn, has a less detrimental effect on the visual appearance of a building after the insulating process has been completed.
In some embodiments of the invention the steps of forming in relation to each first elevation and the or each second elevation respective opposed pairs of openings extending into the associated cavity thereof, when applied to a building in which the face of an adjacent elevation is not accessible, includes forming each opening at an acute angle through a face of the elevation associated with the cavity in question.
Such a step allows the method of the invention to bring the benefit of a reduced overall number of openings, and associated reduced visual impact, to buildings in which the cavity in question lies perpendicular to a party wall (e.g. in a semi-detached house).
There now follows a brief description of a preferred embodiment of the invention, by way of a non-limiting example, with reference being made to the accompanying drawings in which:
Figure 1 shows a method of insulating a building according to an embodiment of the invention;
Figure 2 shows a cavity lying behind an elevation of the building shown in Figure 1; and
Figure 3 shows a sequence of filing a cavity associated with each elevation of the building shown in Figure 1. A building for insulating according to an embodiment of the invention is designated generally by the reference numeral 10 and is shown in Figure 1.
The building 10 has four elevations A, B, C, D, each of which has an associated cavity 12 that lies therebehind, as shown in Figure 2.
Returning to Figure 1, the building 10 includes three first elevations A, B, C, each of which has at least one aperture 14a, 14b formed therein to receive a window element 16.
More specifically, a front facing first elevation A includes a ground floor window element receiving aperture 14a and two first floor window element receiving apertures 14b. A side facing first elevation B includes a single first floor window element receiving aperture 14b. Meanwhile a rear facing first elevation C includes a ground floor window element receiving aperture 14a and two first floor window element receiving apertures 14b.
The building 10 also includes one second elevation D which is devoid of any window element receiving apertures 14a, 14b. The second elevation D in this instance is a side facing elevation.
In other embodiments of the invention (not shown), the building 10 may include a different number of first and second elevations A, B, C, D. Also, each of the first elevations A, B, C may include a different number and arrangement of ground and first floor window element receiving apertures 14a, 14b. A method of insulating the building 10 shown in Figure 1 includes forming opposed pairs of openings 18 that extend into the cavity 12 associated with each of the first elevations A, B, C at each of a low level 20a, a mid level 20b and a high level 20c. Also opposed pairs of openings 18 that extend into the cavity 12 associated with the second elevation D are formed at each of a mid level 20b and a high level 20c.
As such, respective opposed pairs of openings 18 formed at the low, mid and high levels 20a, 20b, 20 care present in each of the first elevations A, B, C, while opposed pairs of openings 18 at the mid and high level 20b, 20 care present in the second elevation D.
An insulant material (not shown) is then injected into the associated cavity 12 of each elevation A, B, C, D via the corresponding openings 18 in the following order:
First, the low level 20a in each first elevation A, B, C and the mid level 20b in the second elevation D, starting in a given elevation A, B, C, D and moving to an adjacent elevation A, B, C, D around the building 10 in an anti-clockwise direction.
Next, the mid level 20b in each first elevation A, B, C, starting in a given first elevation A, B, C, D and moving to an adjacent first elevation A, B, C, D around the building 10 in an anti-clockwise direction .
Finally, the high level 20c in each first elevation A, B, C and the second elevation D, starting in a given elevation A, B, C, D and moving to an adjacent elevation A, B, C, D around the building 10 in an anti-clockwise direction .
It will be appreciated that the insulant material may be injected into the associated cavity 12 of each elevation A, B, C, D by moving around the building 10 in a clockwise direction.
Figure 3 shows an example sequence of injecting the insulant material into the associated cavity 12 of each elevation A, B, C, D, going from arrow “a” to “v” in alphabetical order. It can be seen that the cavity 12 associated with each elevation A, B, C, D is injected in turn around the building 10, apart from when going from arrow “j” to “k”, in which the second elevation D is skipped.
In this embodiment, the sequence of injecting the insulant material begins in a given elevation which has a door element receiving aperture 15 formed therein, which in this case is either elevation A or C.
In relation to the side facing first elevation B (which includes only a first floor window element receiving aperture 14b), the step of forming an opposed pair of openings 18 at a mid level 20b includes positioning the mid level 20b below the first floor window element receiving aperture 14b.
More specifically, the mid level 20b in the side facing first elevation B is positioned no more than 300 mm (or 3 courses of brick) below the first floor window element receiving aperture 14b. Preferably, the mid level 20b is positioned around 225 mm below the first floor window element receiving aperture 14b.
It will be understood that a standard brick has a height of approximately 75 mm, and so 3 courses of brick is the same as approximately 225 mm.
Meanwhile, in relation to the front and rear facing first elevations A, C (each of which includes a ground floor and two first floor window element receiving apertures 14a, 14b), the step of forming respective opposed pairs of openings 18 at a mid level 20b includes positioning the mid level 20b between the ground floor window element receiving aperture 14a and the first floor window element receiving apertures 14b.
In particular, the mid level 20b in each of the front and rear facing first elevations A, C is also positioned no more than 300 mm (or 3 courses of brick) below each of the first floor window element receiving apertures 14b. Preferably, the mid level 20b is positioned around 225 mm below each of the first floor window element receiving apertures 14b
In other embodiments of the invention (not shown) where the side facing first elevation B (or any of the first elevations A, B, C, for that matter) includes only a ground floor window element receiving aperture 14a, the step of forming in relation to the or each corresponding first elevation A, B, C respective pairs of openings 18 at a mid level 20b may include positioning the mid level 20b above the ground floor window element receiving aperture 14a.
In this regard, the mid level 20b in the or each first elevation A, B, C having only a ground floor window element receiving aperture 14a may be approximately 400 mm above the ground floor window element receiving aperture 14a.
In relation to the second elevation D (which is devoid of any window element receiving apertures 14a, 14b), the step of forming an opposed pair of openings 18 at a mid level 20b includes positioning the mid level 20b between the low level 20a and the high level 20c in an adjacent first elevation, i.e. front or rear facing first elevations A, C.
As such, the opposed pair of openings 18 at the mid level 20b formed on the second elevation D are positioned at a pseudo-mid level 22. In the embodiment shown in Figure 1, the pseudo-mid level 22 is positioned below the mid level 20b of each of the first elevations A, B, C. In other embodiments of the invention (not shown) the pseudo-mid level 22 may be above the mid level 20b of each of the first elevations A, B, C.
The step of forming in relation to each of the first elevations A, B, C and the second elevation D respective opposed pairs of openings 18 at a high level 20c includes positioning the high level 20c in the corresponding first and second elevations A, B, C, D below a ceiling line 24 of the respective elevation A, B, C, D, with the ceiling line 24 being defined by a ceiling joist (not shown) of the building 10.
In particular, the high level 20c in each of the first and second elevations A, B, C, D is positioned not more than 500 mm (or 5 courses of brick) below the ceiling line 24. Preferably, the high level 20c is positioned around 375 mm below the ceiling line 24.
The ceiling line 24 is only shown on the side facing first elevation B and the second elevation D in Figure 1 for the purpose of clarity.
The step of forming in relation to each of the front and rear facing first elevations A, C (each of which has a ground floor window element receiving aperture 14a) respective opposed pairs of openings 18 at a low level 20a includes positioning the low level 20a below the ground floor window element receiving aperture 14a.
The low level 20a in each of the front and rear facing first elevations A, C is positioned not more than 300 mm (or 3 courses of brick) below the respective ground floor window element receiving aperture 14a. Preferably, the low level 20a is positioned around 225 mm below the respective ground floor window element receiving aperture 14a
Meanwhile, the step of forming in relation to the side facing first elevation B (which has only a first floor window element receiving aperture 14b) an opposed pair of openings 18 at a low level 20a includes positioning the low level 20a below the ground floor window element receiving aperture 14a formed in another first elevation (i.e. the front or rear facing first elevations A, C). As such, the opposed pair of openings 18 formed at the low level 20a in the side facing first elevation B are in alignment with the opposed pair of openings 18 formed at the low level 20a in the front and rear facing first elevations A, C.
Positioning the mid level 20b in the second elevation D includes positioning the said mid level 20b not more than 2 metres from a support surface 26 on which the building 10 is constructed. Indeed, the pseudo-mid level 22 on the second elevation D is positioned approximately 2 metres from the support surface 26.
The steps of forming in relation to each first elevation A, B, C and the second elevation D respective opposed pairs of openings 18 extending into the associated cavity 12 thereof includes forming each opening 18 through a face 28 of an adjacent elevation A, B, C, D so that the resulting opening 18 lies substantially parallel with the elevation A, B, C, D associated with the cavity 12 in question.
For example, as shown in Figure 2, an opening 18 is formed through the face 28 of the side facing first elevation B that extends into the cavity 12 associated with the front facing first elevation A, so that the opening 18 lies substantially parallel with the front facing first elevation A.
Each of the first and second elevations A, B, C, D, and their associated faces 28, in the embodiment shown are accessible (e.g. the building 10 is a detached house), and as such the aforementioned step of forming each opening 18 through a face 28 of an adjacent elevation A, B, C, D is possible.
However, in other embodiments of the invention (not shown) in which the face 28 of an adjacent elevation A, B, C, D is not accessible (e.g. the building is a semi-detached house), the steps of forming in relation to each first elevation A, B, C and the or each second elevation D respective opposed pairs of openings 18 extending into the associated cavity 12 thereof includes forming each opening 18 at an acute angle through a face 28 of the elevation A, B, C, D associated with the cavity 12 in question.
As shown in more detail in Figure 2, each of the first and second elevations A, B, C, D has an external wall 30 and an internal wall 32 that is spaced from the associated external wall 30. The internal and external walls 32, 30 define a cavity wall. Moreover, the internal and external walls 32, 30 are masonry walls. The internal walls 32 are not accessible from the outside of the building 10.
The external walls 30 in the embodiment shown are made from bricks while the internal walls 32 are made from concrete blocks. The external and internal walls 30,32 may instead be made from any suitable building construction material, such as stone or granite.
The external walls 30 of each adjacent elevation A, B, C, D meet to form a respective external corner 34, while the internal walls 32 of each adjacent elevation A, B, C, D meet to form a respective internal corner 36 . In the embodiment shown, the external walls 30 of each adjacent elevation A, B, C, D meet at 90°, and so form respective right angled corners. Similarly, the internal walls 32 of each adjacent elevation A, B, C, D meet at 90° so as to form respective right angled corners.
In other embodiments of the invention (not shown), the external wall 30 may not have an external corner 34, e.g. in a semi-detached house. In such an embodiment, what would have been the external wall 30 of one of the elevations A, B, C, D is not accessible from outside of the building 10, and so instead that wall 30 is considered a party wall (not shown). The party wall meets the accessible external wall 30 of adjacent elevations A, B, C, D to form a party corner which is also not accessible from outside of the building 10. In this instance, the cavity 12 of that elevation A, B, C, D is formed between the internal wall 32 and the party wall.
In further embodiments of the invention (not shown), the external walls 30 of each adjacent elevation A, B, C, D and the internal walls 32 of each adjacent elevation A, B, C, D may meet one another at an angle other than 90°.
In the embodiment shown, each of the opposed pairs of openings 18 at the low (if appropriate), mid and high level 20a, 20b, 20c in one elevation A, B, C, D are formed before moving onto the next elevation A, B, C, D. Alternatively, each opposed pair of openings 18 at the low level 20a on each of the first elevations A, B, C may instead be formed first before forming each opposed pair of openings 18 at the mid level 20b on each of the first and second elevations A, B, C, D followed by forming each opposed pair of openings 18 at the high level 20c on each of the first and second elevations A, B, C, D.
The cavity 12 is then filled with the insulant material via the opposed pairs of openings 18 in the order shown in Figure 3. More specifically, the opposed pairs of openings 18 at the low level 20a in elevation C are filled first, then the pseudo-mid level 22 in elevation D before moving onto the low level 20a in elevations A and then B. This first stage of filling can be carried out by a technician whilst standing on ground level (i.e. the support surface 26) without the need for a ladder. This is because the pseudo-mid level 22 in elevation D is positioned not more than 2 m from the support surface 26.
The technician then fills the cavity 12 via the opposed pairs of openings 18 at the mid level 20b in elevation C, skips elevation D and then moves onto the mid level 20b in elevations A and then B. In this second stage of filling, the technician is required to use a ladder to reach the mid level 20b. The technician can set the ladder to one height and move around the building 10 without the need to change the ladder height.
Lastly, the technician fills the cavity via the opposed pairs of openings 18 at the high level 20c in each elevation in the same order as before, i.e. elevations C, D, A then B. The high level 20c is the same for all elevations A, B, C, D and so the ladder height need only be changed once to transition between the second and third stages of filling.
It will be appreciated that each of the aforementioned first, second and third stages of filing may be carried out in a different elevation order A, B, C, D, for example each stage of filling may begin at elevation A instead of elevation C.
Each of the openings 18 described above are formed by drilling a hole through each external wall 30 via the associated face 28 into the associated cavity 12. The openings 18 are typically between 18 mm and 22 mm in diameter. The openings 18 are formed through the mortar that lies between adjacent bricks of the external wall 30.
Moreover, the openings 18 are formed between approximately 100 mm and 140 mm from the external corner 34 of each elevation A, B, C, D.
In addition, the insulant material is injected into the associated cavity 12 via an injector 38, as shown in Figure 2, which incorporates a nozzle which penetrates the external wall 30 beyond the internal corner 36 and into the adjacent cavity 12.
