Abstract
An insulating panel for use in construction has a central layer, a first water-resistant coating and a second water-resistant coating on opposite sides of the central layer. The first coating and the second coating are joined to the central layer with a glue layer or a thermo-adhesive material. Each of first coating and the second coating is a plastic sheet that is scratched or abraded.
Claims18
An insulating panel for use in construction, the insulating panel comprising:
- a central layer formed of an insulating foam and water-resistant material having a low specific weight and high dimensional stability, said central layer having a front side and a back side;
- a first water-resistant coating joined to the front side of said central layer;
- and
- a second water-resistant coating joined to the back side of said central layer, each of said first water-resistant coating and said second water-resistant coating being adhered by a glue layer or a thermo-adhesive material to the respective front side and the back side of said central layer, wherein each of said first water-resistant coating and said second water-resistant coating is a plastic sheet having a thickness of 0.2 millimeters with a tolerance of 0.1 millimeters and a density of 1.1 kilograms per cubic decimeter with a tolerance of 0.2 kilograms per cubic decimeter and a hardness of D75 with a tolerance of 20, wherein said first water-resistant coating has an exterior surface that is scratched such that the insulating panel has a tear resistance of no less than 0.5 Newtons per square millimeter.

A process for forming an insulating panel, the process comprising:
- making a foamed sheet as a central layer of the insulating panel;
- curing the foamed sheet into a plurality of thinner sheets;
- preparing a coating;
- abrading the coating by mechanically cutting an outer surface of the coating so as to scratch the coating with uniformly distributed non-through incisions;
- joining the abraded coating onto the foamed sheet with a glue layer interposed between the abraded coating and the foamed sheet or with a thermal adhesive, the coating being symmetrically applied to opposite sides of the foamed sheet;
- cutting the foamed sheet with the coating to a desired size into finished panels;
- and
- packing and moving the finished panels for transport, wherein the step of abrading is carried out by sanding or brushing.
