US 2016/0237680 A1 · Hatch with Thermally Broken Frame

Abstract

A roof access hatch, which utilizes thermal breaks is disclosed. This roof access hatch has a cover with a first metallic exterior surface spaced from a first metallic interior surface by at least a first insulation layer, where the first metallic exterior surface is thermally isolated from the first metallic interior surface. A first thermal break spans the insulation layer and is in contact with both the metallic exterior surface and the metallic interior surface. A frame supports the cover. This frame has a second metallic exterior surface separated from a second metallic interior surface by at least a second insulation layer, where the second metallic exterior surface is thermally isolated from the second metallic interior surface by a thermal break component. A non-metallic, thermally insulating gasket is disposed between the cover and the frame.

Dependent claims

A compound thermal break component, comprising:

a first thermal break component having a first metallic heat conducting portion and a second metallic heat conducting portion separated by at least one thermally insulating portion wherein the first metallic heat conducting portion and the second metallic heat conducting portion are generally parallel to each other in the direction of a first length-wise axis;
and
a second thermal break component having a third metallic heat conducting portion and a fourth metallic heat conducting portion separated by at least one thermally insulating portion wherein the third metallic heat conducting portion and the fourth metallic heat conducting portion are generally parallel to each other in the direction of a second length-wise axis;
wherein the first length-wise axis is perpendicular to said second length-wise axis.
