US 12,644,330 B2 · Thermal barrier

Abstract

The present disclosure describes methods of forming thermal barriers or breaks in tubular structures configured for inclusion in a variety of construction products and building features, such as doors and windows. Methods involve using one or more connector members to couple complementary extrusion profiles, which may comprise aluminum or other conductive materials. A low-conductivity material may then be deposited directly over the connector members coupling the extrusion profiles to form thermal barriers therebetween. At least a portion of the extrusion profiles may be knurled to improve the bond strength between the low-conductivity material, which may comprise polyurethane, and the extrusion profiles. Specialized components may be unnecessary to form the thermal barriers, such that the same connector members used to couple the extrusion profiles may be used to form the thermal barriers.

Dependent claims

A thermal barrier structure, comprising:

two extrusion profiles coupled via at least one connector member, the two extrusion profiles comprising terminal protrusions and opposing hammer portions that, together with the at least one connector member, form a longitudinal channel between the extrusion profiles, wherein the two extrusion profiles and the at least one connector member together define a tubular structure defining a hollow interior, and wherein the at least one connector member lacks serrations, teeth, hollow interiors, and flexible protrusions;
and
a pourable elastomeric material cured within the longitudinal channel, opposite the hollow interior,
wherein the terminal protrusions define exterior surfaces of the extrusion profiles, and wherein terminal tips of the terminal protrusions define a maximum cross-sectional width of the longitudinal channel.
