Description
TITLE OF THE INVENTION:
18
Roof Cladding Element Etc.
BACKGROUND OF THE INVENTION:
This invention relates to a roof cladding element and to a lining system for a roof of a building, particularly, although not-exclusively, for a pitched roof.
From EP 0206011 is known a building industry laminate board exhibiting thermal insulating properties comprising a layer of expanded polystyrene, to each opposite surface of which is bonded, using adhesive, a bubble film, whilst the standard roofing technique in the UK is to employ waterproof roofing felt, supplied in rolls, which is laid orthogonally across the conventionally spaced timber trusses, before the subsequent fitting of tiles, slates, etc., so that in effect there is little or no thermal insulation of the roof and consequently of the loft of a house for instance.

OBJECT OF THE INVENTION
JNL NO
A basic object of the invention is the provision of an improved roof cladding element having thermal insulation characteristics, and an improved roof lining system.
SUMMARY OF THE FIRST ASPECT OF THE INVENTION:
According to a first aspect of the present invention, there is provided a roof cladding element comprising a laminate made up of an oblong slab of polystyrene of such thickness as to be self-supporting and of such width(s) that it will fit between timber roof trusses at standard spacing(s) and thereby will in-fill the space that would otherwise exist between adjacent trusses, to one surface of which slab is bonded a bubble sheet, which sheet has projecting margins
-2extending beyond both the opposed longitudinal sides of the slab, and also beyond one end of the slab whereby, upon installation, adjacent cladding elements are capable of having the sheet margins overlapped.
Preferably, a cladding element in accordance with the first aspect is also provided with a fire resistant coating applied to the sheet, preferably by applying a fire resistant aluminium foil to the bubble sheet and preferably with a fire retardant additive in the polystyrene. The bubble sheet may be of polyethylene, whilst the polystyrene may be expanded or extruded.
SUMMARY OF THE SECOND ASPECT OF THE INVENTION:
According to a second aspect of the invention, of independent significance, there is provided a lining system for a roof of a building comprising a plurality of cladding elements in accordance with the first aspect adapted to be fitted externally or internally to the structure of a roof to provide both thermal insulation and a moisture barrier, with the polystyrene slab located as an in-fill between adjacent trusses with the longitudinal axis of the slab parallel to the trusses, and with adjacent sheet margins of adjacent cladding elements Overlapping one another to ensure a coherent moisture barrier, and with means to locate the cladding elements in position.
With the method in accordance with the second aspect, as the slab width approximates to the spacing between adjacent trusses the individual cladding elements are located between adjacent trusses with the bubble sheet margins extending over the trusses so that two margins pass over each truss to be secured in position, e.g. by nails passing through a counterlath, approximating in width to that of the truss, that secures the two overlapped margins together, into the truss.
Although the cladding elements could be supported with respect to the trusses by
-3securing (e.g. by nailing) timber support blocks to inside faces of the trusses, preferably support clips, e.g. of metal or plastics, are attached to the polystyrene slab. Such clips may be “T”shaped or “Z”-shaped to provide a flange for seating on a surface (e.g. an upper surface) of a truss, particularly in circumstances where the laminate is applied externally before tiles etc., are fitted. The clips may be factory fitted or may be fitted on site by adhesive and/or pins. The clips may be provided with integral pins so that they may be simply pushed into, or hammered into the longitudinal sides of the polystyrene slab at suitable locations with at least four, and typically six or more clips being provided for each cladding element. It follows that, for internal fitting, the laminates need to be nailed or otherwise secured to the trusses.
The cladding elements clearly need to be readily handleable, in which case they may be of 2 m length and, being self-supporting are readily stackable for storage and/or transport.
DETAILED DESCRIPTION OF THE DRAWINGS:
The invention is shown by way of example in the accompanying drawings, in which:
Figure 1 is an underneath plan view of a cladding element in accordance with the first aspect;
Figure 2 is a perspective view of a corner of the element of Figure 1, with the bubble sheet peeled back to reveal a clip;
Figures 3, 4 and 5 are sectional, diagrammatic views of alternative embodiments of external roof lining systems; and
Figure 6 corresponds to Figures 3,4 and 5 but exemplifies an internal roof lining system. In the drawings, a roof cladding clement 1 comprises a laminate made up of an oblong slab 2 of polystyrene of such thickness as to be self-supporting and of such width(s) W that it will fit
-4between timber roof trusses 3 at standard spacing(s) and thereby will in-fill the space that would otherwise exist between adjacent trusses 3, to one surface 4 of which slab 2 is bonded a bubble sheet 5, which sheet 5 has projecting margins 6, 7 and 8 extending respectively beyond both the opposed longitudinal sides 9 of the slab 2, and also beyond one end 10 of the slab 2 whereby, upon installation, adjacent cladding elements 1 are capable of having at least some of the sheet margins 6, 7, 8, overlapped. A fire resistant aluminium foil 11 is applied externally to the bubble sheet and preferably a fire retardant additive is incorporated in the polystyrene. As indicated in Figure 1, the overlap of the margins 6 and 7 may be asymmetrical whilst two “T”Section clips 12 are attached to opposite longitudinal edges. In effecting restoration work by applying the cladding elements internally (e.g. of a slate or tiled roof) non-standard, or irregular truss spacings may require clips 12 attached to one longitudinal edge only, as the other edge may require cutting to size. After cutting, clips may be attached on site, to the newly exposed longitudinal edge of the polystyrene.
The clips 12 are preferably of synthetic plastics with integral pins 13. Alternatively, or in addition to the pins 13, the clips may be secured to the polystyrene by adhesive.
In the lining system illustrated in Figure 3, two adjacent trusses are indicated at 3A, and
3B. At suitable spacings along their mutually facing sidewalls are attached a plurality of timber support blocks 14 on what a face 15 of the slab 2Aof a roof cladding element 1A is seated. The width W of the slab is selected then the slab will comfortably fit between faces 16 of adjacent trusses 3A, and 3B when the latter are located at industry-standard spacing. An end of an adjacent cladding element IB is illustrated to the right of Figure 3. On the truss 3B, margin 7A of element 1A is overlapped on margin 6B of element 2B, or vice versa. A timber counterlath 17 is then applied to the overlapped margins and and secured by nailing into the truss 3B.
-5The embodiment of Figure 4 corresponds to Figure 3 but instead of timber blocks 14 on which the slabs are seated “Z”-shaped clips 18 of synthetic plastics material are employed.
The embodiment of Figure 5 corresponds to Figure 4, details the “T”-Section clips 12 with integral pins 13. The clips 12 may be factory fitted, or fitted on site, by the pins 13 5 penetrating the side edges 9 of the slab 2. The side face of the stem of each clip 12 is located (possibly with slight clearance due to tolerances) against a side of the truss 3, 3A, 3B, with a galvanised nail 19 passing through one side of the “T”-head. After overlapping of edges 6/7 or 7/6 of adjacent roof cladding elements, the counter batten 17 is secured by galvanised nails 19, following which tile battens 20 are applied.
In the embodiment of Figure 6, the roof cladding elements 1 are being fitted internally,
e.g. inside an already tiled or slated pitched roof, so that a plurality of spaced apart, supporting laths 21 secured by galvanised nails are required to hold the elements 1 in place.
Thus, the lining system in accordance with the second aspect of the invention provides both thermal insulation and a moisture barrier, with the polystyrene slab located as an in-fill between adjacent trusses, and with adjacent sheet margins of adjacent cladding elements overlapping one another to ensure a coherent moisture barrier.
