Abstract
An insulative construction product includes a polyurethane foam core and a mixture of Aerogel and carbon black that is disposed within the polyurethane foam core. The mixture of Aerogel and carbon black includes between 90 and 99 weight percent Aerogel and between 1 and 10 weight percent carbon black. The polyurethane foam core includes between 10 and 90 percent by volume of the of Aerogel and carbon black mixture and the construction product has an R-value of at least 8.0 R/inch.
Claims24
A polyurethane foam based construction product having improved insulative properties, the construction product comprising:
- a foam core comprising polyurethane foam;
- and
- a mixture of Aerogel and carbon black disposed within the foam core;
- wherein:
- the mixture of Aerogel and carbon black is enclosed within a barrier material such that the polyurethane foam does not directly contact the Aerogel and carbon black;
- and
- the barrier material is entirely surrounded by the polyurethane foam so that the barrier material is fully enclosed within the foam core.
An insulative construction product comprising:
- a foam core comprising a foam material;
- and
- an Aerogel mixture disposed within the foam core;
- wherein:
- the insulative construction product includes between 10 and 90 percent by volume of the Aerogel mixture;
- the Aerogel mixture is contained within a barrier material that is entirely surrounded by the foam material so that the barrier material is fully enclosed within the foam core;
- and
- the barrier material prevents direct contact between the foam material and the Aerogel mixture.
A method of forming a construction product with improved insulative properties, the method comprising:
- providing a foam core comprising foam material;
- positioning an Aerogel mixture within the foam core;
- separating the Aerogel mixture from the foam material via a barrier material so that the foam material does not directly contact the Aerogel mixture and so that the barrier material is fully enclosed within the foam core;
- wherein the foam core includes between 10 and 90 percent by volume of the Aerogel mixture.
