Description
FRAMES FOR BUILDING PANELS
This invention relates to frames for building panels, in particular for doors and windows.
Such frames are commonly fabricated from separate members in the form of lengths of plastics material, commonly PVCU, or aluminium. The present invention is particularly concerned with the members that make up the frames. These members are normally fabricated by extrusion and have a cross sectional shape, referred to herein to as its profile, which suits the particular application. Usually the profiles will be hollow and if made of plastics material, will often be reinforced by an elongate reinforcement member, typically of rectangular section steel tube, contained within the profile. Doors and windows are generally made in the form of an outer frame which is screwed or otherwise affixed to the fabric of Is the building in which it is being installed. This outer frame will generally be fabricated from four members which may be of different profile according to their position in the frame. In addition, window frames in particular are often subdivided by transoms and/or mullions according to the particular requirements. These transoms and mullions, if fitted, thus simply comprise further members of the frame. Furthermore, all or part of the frame may be fitted with a sash, usually openable, which is itself made up of similar members to those described above. The present invention is applicable to any of these members, whether making up the outer window or door frame or a sash thereof, and including any transoms or mullions which may be fitted.
The present invention is primarily concerned with the thermal performance of the frames. EP-A-1070821 describes a hollow member made of plastics material and having a reinforcement member therein.
Thermal performance is enhanced by defining within the profile air chambers which are formed across the main flow of heat between the inner and outer walls of the profile. These air chambers are defined by providing - 2 internal formations which locate the reinforcement member within the profile in such a way that the reinforcement member itself defines one wall of the air chamber.
The technique described in EP-A-1070821, whilst improving the thermal performance, has a number of disadvantages which the present invention seeks to address. For example, the fact that the reinforcement member, usually made of metal, is used as a wall of the air chamber, itself detracts from the thermal efficiency of the profile. Also, the requirement to provide special internal formations to locate the to reinforcement dictates that a special profile needs to be used for this purpose - it is generally not possible to use existing profiles.
According to the present invention there is provided an elongate composite member for fabricating frames for building panels, said member comprising an elongate profiled element defining a hollow interior, Is at least one hollow intermediate element located within said hollow interior, said intermediate element being made of a low thermal conductivity material and being arranged to provide at least one air chamber located across the main heat flow path through the composite member.
In an embodiment, the or at least one of the intermediate so elements has a hollow interior in which is located a reinforcing element. In the preferred embodiment of the invention, just a single intermediate element is used, and this has a hollow interior divided into a plurality of chambers, said elongate reinforcing member being located within one of said chambers.
The or each chamber which is not fitted with a reinforcing member acts as a thermal barrier and, as such, is positioned so as to best interrupt the flow of thermal energy from the inside side of the profile to the outside side, or vice versa. Thus, preferably the or each chamber which is not fitted with a reinforcing member is positioned across the main flow path so of heat through the profile. This is not to say that additional cavities cannot be positioned elsewhere, for special purposes, but the primary purpose is - 3 to limit the flow of heat along the main flow path of heat, which is usually from inside to outside and vice versa.
In a preferred embodiment of the invention two thermal barrier cavities are provided, one on each side of the reinforcing member cavity, in the direction of the main heat path through the profile - this arrangement effectively sandwiches the reinforcing element, which usually is made of metal and is thus a poor thermal insulator, between the two thermal breaks created by the thermal barrier cavities.
In an alternative arrangement the hollow interior of the lo profiled element contains more than one elongate intermediate elements, each of which either contain a reinforcing element, or define a thermal barrier cavity. Each intermediate element can itself be partitioned to define multiple interior cavities which can either house reinforcing element, or act as thermal barriers. The exact arrangement can be adjusted for the Is particular circumstances of use.
The intermediate element is made from a material having low thermal conductivity, for example plastics material. Since the intermediate element is not visible once fitted, it can be made of cheaper lower grade material than the profile itself.
so Preferably the intermediate element is a close but not tight fit within the hollow interior of the profiled element so that, during fabrication, it can be readily slotted into place. The intermediate element can be lightly held in place within the interior by means of a screw applied through the profiled element, as is common practice to securely locate reinforcing elements. Alternatively, the intermediate element, if made of a suitable material, can be welded to the profiled element, for example at the ends after cutting utilising the existing manufacturing process. If multiple intermediate elements are used, it is preferred that, when placed together correctly as a single unit, they slot easily into the hollow interior of the so profiled element, and locate therein without excessive movement - once again they can be more securely fixed using one or more screws applied - 4 through the profiled element, or by welding.
In order that the invention may be better understood, several embodiments thereof will now be described by way of example only, and with reference to the accompanying drawings in which: Figures 1 to 11 each illustrate a cross section of an elongate composite member, according to the invention, for fabricating a window or door frame, or a sash therefore.
Each of the Figures shows a respective section of a part of a door or window frame: Figure 1 shows a Z transom or mullion window Jo profile; Figures 2, 5, 6 and 9 to 11 each show a standard window frame profile; Figures 3 and 7 each show a T sash window profile; Figure 4 shows a Z sash door profile; and Figure 8 shows a T transom or mullion window profile. These profiles are given as examples of possible profiles incorporating the present invention; it will be understood that the exact Is shape or purpose of the profile is not relevant to the invention.
It will be seen from the drawings that, despite their different shapes, the various profiles all have a hollow interior which can be a different shape and size. Thus, referring initially to Figure 1, the composite member comprises an elongate profiled element 1 which is shaped for the to particular purpose to which it is to be applied - in this case a transom or mullion for a window frame. The element 1 is made of thermoplastic material, typically PVCU. The element has a hollow interior 2 of a generally rectangular shape in which is located an intermediate element 3. The intermediate element 3 is of elongate shape, and is typically fabricated from plastics material by extrusion. Materials other than plastic can be used for the intermediate member, but it should be borne in mind that the purpose of the intermediate member is to create a thermal barrier and therefore materials possessing low thermal conductivity are necessary. However, since the intermediate element is hidden from view, and is protected from so the weather, poorer grade plastics, including recycled plastics, can be used in its fabrication in order to save on costs. - 5
The shape of the intermediate element 3 is such as to match the interior shape of the profiled element 1 so that the intermediate element will fit snugly into the profiled element 1, but preferably without tightness for ease of fabrication.
The hollow interior of the intermediate element is partitioned into three chambers 4, 5 and 6. The central chamber, reference 5, locates a reinforcing element 7 in the form of a rigid hollow bar. This bar is made of a strong material which will provide internal strengthening and stiffening for the profile as a whole. Metals such as steel or aluminium are the to preferred materials, but non-metallic materials can be used, for example glass reinforced plastics material or carbon fibre.
The chambers 4, 6 either side of the chamber 5 are air chambers and act as thermal barriers to the main flow path for heat through the profile, namely from left to right, and vice versa, in Figure 1.
The thermal performance of a profile is determined by the rate of flow of heat energy across the profile from the inside side of the profile to the outside side, and vice versa. In the case of the profile of Figure 1, the area through which heat primarily flows is approximately between the dashed lines 8,9 in Figure 1. Flow of heat above and below no these lines is primarily determined by other components (not shown) of the window and do not concern the present invention. Essentially the present invention seeks to improve the thermal properties across the area bounded by the dashed lines 8,9. Hitherto these thermal properties have been adversely affected by the presence of the reinforcing element, which would normally fill the space occupied by the intermediate element 3. Since the reinforcing element is normally made of metal, often steel, having a high thermal conductivity, the presence of the reinforcing element increases the overall thermal conductivity of the horizontal path between the lines 8 and 9. In the present invention, not only is the reinforcing element physically JO smaller, which itself reduces the thermal conductivity, but it is also, in the horizontal direction of heat flow across the profile, insulated on either side - 6 by the aforesaid thermal barriers formed of chambers 4 and 6.
Figures 5 and 7 illustrate embodiments similar to those of Figures 2 and 3 respectively in which the chambers formed within the intermediate element 3 are arranged so as to enable the reinforcing element 7 to be located in a position which more readily enables window hardware (not shown) to be screwed into the reinforcing element. To this end, the intermediate element has three chambers 20, 21 and 22 in which the right- hand larger chamber 20 locates the reinforcing element 7 and the two smaller chambers 21, 22 together act as a thermal barrier.
to In the areas above and below the intermediate element 3, air chambers 10 are formed, in a similar manner to the arrangement described in EP-A1070821, by the interaction of the intermediate element 3 with the internal walls of the hollow interior 2 and the various spacer members 11 extending inwards from the internal walls. However, unlike the arrangement described in EP-A-1070821, all walls of the chambers 10 so formed are made of low thermal conductivity material.
Thus, it will be seen that, whatever route heat energy takes in flowing across the profile, it must necessarily pass across at least one, and most likely several, air chambers. These air chambers 4, 6 and 11 act as so thermal barriers, having poor thermal conductivity, and resist the passage of heat energy.
The fact that the reinforcing element 7 is smaller, and therefore, like for like, of lower strength and stiffness is not normally a problem because the majority of applications will be covered; however, the reinforcing element, although physically smaller, can be strengthened for high-load applications by, for example, using heavier gauge material.
Sometimes, however, and dependent on specification, the fact that the reinforcing element is smaller will be an advantage because, not only is the additional strength not needed, but the smaller section means that the So reinforcing element uses less material and is therefore cheaper.
It will also be seen that the arrangement shown allows the - 7 thermal performance to be readily tailored for particular circumstances: the hollow interior 2 may simply be filled with the reinforcing element essentially the prior art arrangement, and giving a reduced thermal performance; alternatively, an intermediate element 3, as shown in Figure 1 can be fitted giving improved thermal performance. Still further improvements in thermal performance can be achieved by fabricating the intermediate element 3 with multiple air chambers on either side of the chamber 5 which carries the reinforcing element 7: thus by fitting the appropriate intermediate element 3 during fabrication (or even no to intermediate element at all, just a reinforcing element) an appropriate level of thermal performance can be achieved for a particular profile.
Figures 2 to 4 show the application of the invention to various other typical profiles. The above explanation will not be repeated but it will be seen that the principles are essentially the same for each of the illustrated profiles; the same reference numerals have been used throughout the drawings.
Figures 6 and 8 illustrate embodiments similar to Figures 5 and 7 respectively but in which the reinforcing element 7 is not located within the intermediate element 3 but is located next to it within the hollow so interior 2 of the profiled element 1. In each case, the intermediate elements 3 is divided into a pair of chambers 23, 24 which provide thermal insulation. Optionally, the intermediate element 3 may be adhered to the reinforcing element 7, for example by means of adhesive tape 25, as shown.
Reference is now made to Figure 9 which illustrates a profiled element 1 similar to that of Figure 2, by way of example, but in which the intermediate element 3 does not in itself define one or more chambers but instead divides up a volume within the hollow interior 2 into a plurality of chambers. Various shapes can be employed for this purpose, but it will be So seen that the particular shape illustrated in Figure 9 is such as to create six chambers 33 to 38 to the right of the reinforcing element 7. The - 8 intermediate element 3 may or may not be attached to the reinforcing element 7. The thermal insulation provided by this version may not be as effective as that obtained by the above described versions, but it is an improvement over having the hollow interior 2 completely filled by the reinforcing element, which is the common arrangement currently.
Figure 10 illustrates a variant of the Figure 9 embodiment for deeper sections. In this case, two reinforcing elements 71, 72 are provided, each having a respective intermediate element 31, 32. Inwardly directed from the internal walls of hollow interior 2 are lugs 39 which act to Jo locate the reinforcing elements 71, 72 and intermediate elements 31, 32 within the hollow interior 2. Once again, it will be seen that the arrangement creates multiple chambers within the hollow interior which act to form a thermal barrier across the profiled element 1.
Figure 11 illustrates a still further embodiment which is similar! i5 to that of Figure 9, but having a differently-shaped intermediate element 3.
The intermediate element 3 is shaped as two channel sections 40, 41 facing away from one another and joined by a web 42. Each of the channel sections has legs which, in the case of channel section 40 form a gripping means which acts to grip the end of the reinforcing element 7 due to the So resilience of the plastic legs and, in the case of channel section 41, act to define, with the end wall of hollow interior 2, a chamber 43. Further chambers 44, 45 are also created above and below the intermediate i element 3. - 9 -
