(001) This invention relates to insulated roof panels for conservatory roofs and similar roofing structures.

(002) It is common that conservatory roof structures are provided with polycarbonate sheeting which is twin wall multi chamber construction and provides little insulation.

(003) Such structures lead to typical conservatory buildings becoming hot in summer and cold in winter.

(004) It is known that conservatory type buildings may be provided with a

lightweight tile supported by an aluminium roofing system and that these

improvements are very costly .

(005) It is known that vacuum panels are available and provide a very efficient form of insulation which can be around five times more efficient than other insulation such as rock wool.

(006) Vacuum panels consist of a panel of rigid highly porous material such as fumed silica/aerogel, perlite or glass fibre, to support the membrane walls against

atmospheric pressure once the air is evacuated

(007) Said insulated vacuum panels or VIPs can not be cut to size and therefore have restricted uses within the housing market.

(008) According to the present invention there is provided a plurality of roofing panels and each panel comprising of two flat sheets of plastics,glass or other sheet material laminated to a either side of one or more Vacuum Insulation Panel(s) and said sheet material may be wider and or longer than the encapsulated VIP (s) and that the encapsulation forming a roofing panel may be provided with an enclosed internal perimeter formed of aero gel composite insulation blanket or other insulation material and that the encapsulation may be provided with a seal or outer boarder of dense material around the outer perimeter thereby protecting the VIP(s) and also to prevent deterioration of the aero gel and that the compete roofing panel may encapsulate one or more predetermined size, mass produced VIP(s) yet allowing for the roofing panel(s) to be produced to varying width and length or that the roofing panel(s) may be produced to stock sizes and trimmed to made to measure size on request and the encapsulation forming a panel containing one encapsulated VIP may be produced in the form of a roof tile and a plurality of said roof tiles may be inserted within and or attached to a grid which may be positioned between roof spars of a typical conservatory roof or supported by a plurality of rigid members attached to a roofing structure and said roof tile may be produced from one or more vacuum formed, press formed or moulded sections which encapsulate a VIP which may be provided with a border of composite aero gel blanket and or other insulation material to allow for said roof tile to be cut or trimmed or the encapsulation forming said roof tile may contain a single thermally efficient material allowing for said tile to be cut or trimmed to shape when necessary.

(009) It is preferred that the VIP(s) fig 1 members 1, 2 and 3 be mass produced in two sizes 400mm x 600mm and 400mm x 800mm surrounded by a perimeter of aero gel composite insulation blanket which is surrounded by a outer framework of rigid styrene or other dense material to protect the aero gel from deterioration and that the boarder of insulation allows for roofing panels to made to measure and be produced to fit to varying size roof structures.

(010) It is preferred that the panels be produced at 32mm in thickness to match the dimension of existing polycarbonate sheet and so as to fit to most conservatory roofing spars however they may be produced at other industry standard sizes of 25mm and 35mm.

(011) It is preferred that the VIPs have a rigid core of Fumed Silica Aero gel, allowing for a roofing panel at 32mm thickness to achieve a U value of 0.25, the building regulation standard for a domestic new build insulated exterior cavity wall.

(012) The insulated roofing panels may be supplied to be fitted to new conservatory's or retro fit to existing by replacing the original polycarbonate. A quick and easy procedure.

(013) It is preferred that the internal perimeter material be aero gel composite insulation blanket , fig 1 member 4.

(014) It is preferred that the outer perimeter be of a rigid styrene or other dense material, fig 1 member 5.

(015) The encapsulation forming a panel which encapsulates one VIP may be produced from moulded sections which form of a roof tile and a plurality of said roof tiles may be inserted within and or attached to a grid which may be positioned between roof spars of a typical conservatory roof or supported by a plurality of rigid members attached to a roofing structure.

(016) It is preferred that the sheet material used to encapsulate the VIPs has a flat surface to enable lamination to the VIP(s) however the sheet material may be embossed or recessed to form boarded or tile effect designs.

(017) The insulation panels may be fitted to industry standard conservatory roofs but may also be installed within the glazing recess of windows and doors and

conservatory walling. (018) The sheet material which is laminated to the VIP(s) may be digitally printed and may resemble roof tiles, brickwork or other external or internal designs.

(019) It is preferred that the insulation panel be non combustible.

(020) In order that the invention may be more readily understood embodiments thereof will now be described by way of example only, reference being made to the accompanying drawing wherein :-

Figure 1 shows a plan view of the internal arrangement of a insulated roofing panel whereby members 1 , 2 and 3 are VIPs. Member 4 is internal perimeter of aero gel composite insulation blanket. Member 5 is outer perimeter of rigid styrene.
