Description
WiNDOW THERMAL SHIELD This invention relates to a device for thermally insulating a window, and more specifically to a themial shield for improving the thermal insulation of the frame of a casement window.
Windows consist of two parts, the window frame and the glazing. In windows with a hinged mode of opening, the frame comprises a base structure which is fixed to the structure of the wall or roof opening, and a casement which is typically attached via a hinge to the base structure. Glazing is carried by the structure of the casement frame and may also be carried in the fixed base structure.
Building regulations (or code) is typically used to specify legal standards for structural elements of buildings, including windows. In the UK, Part L of the Building Regulations includes a requirement that the minimum area weighted average thermal conductivity for window units in new dwellings must not exceed 2.0 W/m2.K and for replacement windows in existing dwellings must not exceed 1.6 W/m2.K. A suggested target of 0.9 W/m2.K was published by the Department for Communities and Local Government, London! in 2007 (Building Regulations: Energy efficiency requirements for new dwel/ings -A fonard look at what standards may be in 2010 and 2013). It is likely that future revision of Building regulations and codes will result in increasingly stringent requirements relating to thermal conductivity and air permeability.
The thermal conductivity of an entire window results from a combination of the thermal conductivitios of the frame and the glazing. Where the frame has a relatively high thermal conductivity, it will impose a lower limit on the achievable thermal conductivity for the window as whole. It is therefore desirable that window frames have a sufficiently low thermal conductivity br the glazing to dominate the overall thermal conductivity.
G82306545 discloses a thermal shield for a rooflight with a metal frame in which a thermal shield is interposed between the base frame and the opening. The thermal shieFd both limits the thermal conductivity of the frame and prevents condensation thereon from becoming a problem by forming a channel that carries the condensate outside p ii.
The present applicant has identified a need for an improved thermal shield device in which the level of thermal insulation provided by the shield can be conveniently adjusted to meet the requirements of a particular product or installation.
Perforations are often provided in the frame to allow condensate to escape. However, this can increase the air permeability of the rooflight. It is desirable to provide a rooflight with very low levels of air permeability.

Some embodiments of the present invention will now be described, by way of example only, with reference to the following drawings in which: F Figure 1 is a simplified diagram of a rooflight installed in a pitched roof of a building, seen in cross section on a vertical plane; Figure 2, on a larger scale, is a cross section taken through the closed rooflight at the opposite edge to the hinge, showing part of the rooflight in greater detail; Figure 3 is an enlarged scrap view of the portion within the circle B in Figure 1; Figure 4 is an enlarged exploded scrap view of the structural, thermally insulating and facing elements of a thermal shield; Figure 5 is an enlarged scrap view of a thermal shield; Figure 6 shows an alternative embodiment of the invention wherein the facing element of the thermal shield extends to the interior edge of the opening; Figure 7 shows an alternative embodiment of the invention wherein the thermally insulating element extends into the interior beyond the extent of the frame; and Figure 8 shows an further alternative embodiment of the invention wherein the thermally insulating element extends into the interior beyond the extent of the frame.
Figure 1 shows an opening 1 in a roof in which a rooflight 2 has been installed. The roof may be of any construction, being shown here as having a structure 3 comprising rafters 4. Tiling and appropriate flashings (not shown) provide weatherproofing for the roof. The interior of the roof has a sloping ceiling 5. The interior of the opening in the roof is lined by fascia boards 6.
The rooflight 2 comprises a fixed base 7 and a casement 8. The fixed base 7 is mounted to the rafters 4 by screws or boris (not shown), and comprises a fabricated steel frame. The casement 8 comprises a fabricated steel casement frame 9 and a glazing unit 10. A thermal shield 11 is interposed between the frame of the rooflight (7, 9) and the interior of the opening 1. The thermal shield 11 comprises a structural element 13. thermally insulating element 14, facing element 15 and seal 16 (not shown in Figure 1).
The casement 8 is attached to the fixed base 7 at one horizontal edge by hinges 12, about which the casement 8 can rotate to move between open and closed positions shown in Figure 1 and 2 respectively. The casement frame 9 supports the glazing unit 10.
A section of the rooflight in the closed position through the edge opposite to the hinges 12 is shown in Figure 2. The fixed base 7 comprises a base plate 17 which is parallel 1: with the exterior face of the roof, and which is extended by a continuous rectangular base wall 18 surrounding the opening and projecting outwardly from it.
The structural element 13 of the thermal shield 11 comprises a transverse portion 19 which is parallel to the exterior surface of the roof, and includes a mounting portion 20 extending partly under the base plate 17 by which the thermal shield 11 may be secured to the base plate 17, for instance using adhesive. Alternative[y, the thermal shield may be secured to the rafters 4, for instance using screws (not shown).
The structural element 13 of the themial shield 11 further comprises a baffle portion 21, extending from the transverse portion 19 in a direction out of the opening. The baffle 21 is spaced transversely away from the base wall 18 which is substantially parallel to the baffle 21. The baffle 21 has a C shaped section, and further comprises a recess 22. A seal 16 is carried on the outermost face of the C section which is arranged to be in close proximity to the inner face of the glazing unrt 10 when the rooflight is closed so that the seal 16 cooperates with the glazing unit 10.
The thermally insulating element 14 and facing element 15 are supported within the recess 22 of the baffle 21. The lacing element 15 lines the visible face of the installed thermal shield 11. and is comprised of a material that is chosen for its visual appeal or suitability as a substrate for the required external finish, for exampre paint or emulsion.
The structural element 13 and seal 16 of the thermal shield 11 substanlially prevent contact between the interior air and the frame of the rooflight when the rooflight is c]osed The thermally insulating element 14 provides for a high degree of thermal insulation between the interior air and the rooflight frame. An appropriate material and thickness of the insulating element 14 may be selected based on the required thermal properties of the rooflight By substantially preventing contact between the interior air and the rooflight frame, the seal of the embodiment shown in Figure 2 prevents the majority of condensation that may form on the frame as a result of such contact. In some embodiments of the invention the seal 16 is not present, and even with the seal 16 some condensation may occur from air trapped when the window is closed. A condensation channel is defined by the base wall 18 and the structural element 13 of the thermal shield 11, and F condensation forming on either the casement frame 9 or fixed base 7 will be carried thereby to perforations 24 in the base walE 18 as shown in Figure 3. A seal 28 is provided between the thermal shield 11 and the fixed base 7.
A further seal 27 (not shown in Figure 1, see Figure 7) may be provided between the fixed base 7 and the casement frame 9 in the gap 25 between the upper face of the base waIl 18 and the casement frame 9.
The seal 16 provided to the glazing unit 17 is continuous and may be arranged to provide a low degree of air permeability. A further seal (not shown) disposed in the gap between the casement frame 9 and fixed base 7 may further reduce air permeability.
The depth of the recess 22, and the material and/or thickness of the insulating element 14 may readily be altered to provide different revels of thermal performance, having regard to the cost and size of the thermal shield.
The structural element 13 comprises polyvinyl chloride (PVC), but may comprise alternative prastics materials or a metal such as steel or aluminium.
The thermally insulating element 14 comprises a polyisocyanurate foam, but may comprise alternative polymer foams comprising for example polyurethane, polystyrene or phenolic resin. Alternatively the thermally insulating element may comprise an aerogel or other insulating material.
The facing element 15 comprises oak, but may comprise alternative wood materials, plastics materials, metals, plaster or plasterboard.
Figure 4 shows the elements of a thermal shield 11 in section, with the structural element 13 shown adjacent to the thermatly insulating element 14 and the facing element 15. The structural element has a transverse portion 19 comprising a mounting portion 20, and a baffle portion 21 extending in a perpendicular direction away from the transverse portion 19. The baffle portion 21 comprises a C shaped recess 22. The structural element 13 of the thermal shield 11 is secured to the base plate 17 by adhesive 29.
Figure 5 shows the thermal shield 11 of Figure 4 with the insulating element 14 and the facing element 15 inserted into the recess 22.
Figure 2 shows that there is a discontinuity between the fascia boards U and the thermal shield 11. In an alternative embodiment of the invention shown in Figure 6, the facing element 15 of the thermal shield 11 extends from the inner face of the glazing unit 10 to the interior surface of the ceiling 5. The facing element 15 thereby forms a
P
continuous lining for the opening 1 with no seams or discontinuities, hiding the frame from view and making the rooflight appear frameless from the interior. The facing element 15 is attached to the insulating element 14 which is received in the recess 22 of the structural element 13. Alternatively or in addition, the facing element may be fixed to the rafters 4, for instance by nails or screws.
In Figure 7 an embodiment of the invention is shown in which both the facing eFement and the Lhermally insulaling element 14 extend from the inner face of the glazing unit to the interior surface of the ceiling 5. In this arrangement the structural element 13 does not include a C shaped recess, and the thermally insulating and facing elements 14, 15 are secured to the structural element by adhesive. The facing element 15 extends to the interior surface S of the ceiling, and the thermally insulating element 14 abuts the rear facing surface of the ceiling board. An architrave 31 is provided to provide a pleasing finish at the interface of the ceiling board and the facing element 15.
The mounting portion 20 of the thermal shield 11 is secured to the base plate 19 using adhesive 29. The fixed base 7 of the roofTight is in turn secured to the rafters 4 using screws 30.
In Figure 8, a further alternative embodiment of the invention is shown in which the thermal shield does not have a transverse portion 19, but instead comprises a structural element 13 with a C shaped section which extends substantially from the inner surface of the glazing unit 10 to the face 26 of the ceiling board 5 which is in contact with the rafters 9. A thermally insulating element 14 is supported by the recess 22 of the structural element 13, and a seal 16 is disposed on the surface of the structural element 13 which is in proximity to the glazing unit ilk The seal 16 cooperates with the glazing unit 10 when the window is closed to substantially prevent contact between the frame of the rooflight and the interior air.
In this embodiment the C section of the structural element 13 is modified at the inner edge to accommodate the facing element 15, which extends beyond the structural element 13 to the inner surface of the ceiling 5. The facing element 15 is attached to the insulating element 14. Alternatively or in addition, the facing element 15 may be fixed to the rafters 4 for instance by nails or screws The embodiments described above are given by way of examples only, and various other modifications will be apparent to persons skilled in the art without departing from the scope of the invention, as defined by the appended claims.
It will be appreciated that with an arrangement as described hereinbefore, the thermal insulation provided by the rooflight becomes substantially independent of the frame, being almost entirely dependent on the levels of thermal insulation provided by the thermal shield 11 and the glazing unit 10. This allows the same structural frame to be used for a range of applications with differing thermal insulation requirements, and mitigates the need to make changes to the design of the structural frame of the casement 9 and fixed base 7, for example in response to more stringent building regulations relating to thermal insulation The thermal insulation provided by the thermal shield may readily be altered as required by varying the material and/or thickness of the insulating element 14, as noted above.
Arrangements have been further disclosed wherein a continuous lining face is provided from the interior edge of the opening to the glazing *unit of the rooflight. Such arrangements may provide a window or rooflight in which the frame may thereby be excluded from interior view, and gaps or discontinuities between the thermal shield and separate lining boards may be avoided. This results in a seamless window lining, giving the appearance of a frameless window or rooflight It will be appreciated that although the embodiments described herein relate to a rooflight, the invention may equally be applied to any form of window, including those F attached to openings in wall, and to windows with fixed glazing that are not openabFe.
The embodiments described herein relate to windows with metal frames, but the application of the invention is not so limited, and it may also be applied to improve the performance of windows with frames comprising plastics material andlor wood. I:
