Abstract
A vacuum insulation panel has a non-porous insulating core with an upper surface and a lower surface and sides. An envelope is arranged about the core to envelop the core, and to maintain an applied vacuum within the envelope. A non-foam polyurethane coating layer is applied to the envelope. The coating layer is formed over the entire surface area of the envelope.
Claims14
A vacuum insulation panel comprising:
- (a) a non-porous insulating core having an upper surface and a lower surface and sides;
- (b) an envelope about the core arranged to envelop the core, and to maintain an applied vacuum within the envelope;
- and
- (c) a non-foam polyurethane coating layer applied to the envelope, wherein the coating layer is formed over the entire surface area of the envelope.

A process for manufacturing a vacuum insulation panel, comprising the steps of:
- (i) providing a non-porous insulating core having an upper surface and a lower surface and sides;
- (ii) providing at least one metal foil having a thickness of at least 4 microns which extends across substantially the entire upper surface or entire lower surface of the core so that the foil does not form a thermal bridge between the upper surface and lower surface of the core;
- (iii) providing an envelope having an inside surface and an outside surface, wherein the envelope is arranged to:
- (i) envelop the core and the metal foil, with the metal foil between the envelope and the core, and (ii) to maintain an applied vacuum within the envelope;
- (iv) applying a vacuum to the envelope;
- (v) attaching the metal foil to an inside surface of the envelope after the vacuum has been applied;
- and
- (vi) coating the entire external surface of the vacuum insulation panel with a non-foam polyurethane layer.
