Abstract

A light transmitting, insulating panel comprises one or more layers 2 of cellulose acetate sheeting disposed between outer layers 1 of rigid polyvinyl chloride.The cellulose acetate sheeting may be corrugated, crimped, folded or otherwise profiled to enclose pockets of air. <IMAGE>

Description

SPECIFICATION Light transmitting insulating panel This invention relates to a light transmitting, insulating panel. Such a panel may find application in construction of rooflights for buildings, light transmitting panels for suspended ceilings orforvertical- ly disposed window panels.
According to the present invention a light transmitting, insulating panel comprises one or more layers of cellulose acetate sheeting disposed between outer layers of rigid polyvinyl chloride.
The cellulose acetate sheeting may be corrugated, crimped, folded or otherwise profiled to enclose pockets of air. Two or more layers of sheeting may be disposed in contact or adjacent one another. In a preferred embodiment of the invention consecutive layers are located with the corrugations disposed in an opposed arrangement. The corrugations may be most conveniently disposed perpendicularly allowing minimal wastage during manufacture. A particularly preferred embodiment comprises four layers of cellulose acetate sheet.
The outer layers of rigid polyvinyl chloride may be bonded together to enclose the cellulose acetate.
One or more of the layers may be corrugated or provided with ribs or other members to enhance the mechanical strength and rigidity of the panel. A first layer of polyvinyl chloride may take the form of a tray adapted to receive the cellulose acetate during manufacture. The tray may be provided with strengthening members. This layer may be disposed facing towards the exterior of the building, the second layer facing towards the interior. The second layer may be provided with a decorative surface.
Use of a panel in accordance with this invention affords the advantage of providing heat insulation while admitting either natural or artificial light. The panel finds application in rooflights for example in factories, workshops, schools and hospitals. Alternative uses include North lights, suspended ceilings or vertical window panels. The polyvinyl chloride surfaces may be easily cleaned.
The invention is further described by means of example with reference to the accompanying drawing which shows a perspective cross sectional view of a panel in accordance with the invention.
The drawing illustrates a panel constructed in accordance with the invention. Four layers of corrugated cellulose acetate sheeting 2,4 are disposed with the corrugations of adjacent layers 2,4 generally perpendicular so as to provide layers of air pockets. An outer layer of rigid polyvinyl chloride 1 is provided with corrugations 6 to enhance the mechanical strength of the panel. The layer 1 has the form of a tray so that the cellulose acetate may be located therein during manufacture. A second, noncorrugagted layer of rigid polyvinyl chloride 3 is seam moulded to the layer 1 at 5 to completely enclose the cellulose acetate. The layer 3 may be provided with a decorative surface. The panel may have a U value of 1.45 Wm-2 C.
Cellulose acetate sheeting preferred for use in accordance with this invention is manufactured by Courtaulds.
1. Alighttransmitting, insulating panel comprising one or more layers of cellulose acetate sheeting disposed between outer layers of rigid polyvinyl chloride.
2. A panel as claimed in claim 1, wherein the cellulose acetate sheeting is profiled to enclose pockets of air.
3. A panel as claimed in claim 2, wherein consecutive layers of cellulose acetate sheeting are located with corrugations disposed in an opposed arrangement.
4. A panel as claimed in any preceding claim, comprising four layers of cellulose acetate sheeting.
5. A panel as claimed in any preceding claim, wherein outer layers of rigid polyvinyl chloride are bonded together to enclose the cellulose acetate.
6. A panel as claimed in any preceding claim, wherein one or more of the layers of rigid polyvinyl chloride are corrugated or provided with ribs or other members to enhance the mechanical strength and rigidity of the panel.
7. A panel as claimed in any preceding claim, wherein a first sheet of rigid polyvinyl chloride comprises a tray adapted to receive the cellulose acetate.
8. A panel substantially as hereinbefore described with reference to the accompanying drawing.
