Description

FIELD OF THE INVENTION

This invention relates generally to articles incorporating thermal insulation materials, and more specifically, to solar screen articles and methods thereof.

BACKGROUND OF THE INVENTION

In the past, solar screen materials have been used as thermal insulation materials in solar screen applications. For example, essentially rectangular shaped frames with screen material inserted into them were used for shading and as insect and dust barriers. Thermal solar screens were generally installed on the outside of windows or any other suitable opening in a building, such as a patio.

Current thermal solar screens are a great benefit to buildings because they greatly reduce the amount of heat and glare when installed on the outside of windows, thereby improving energy conservation. Thermal solar screens also provide more privacy inside a building, while allowing full visibility through windows. Thermal solar screens do not inhibit natural ventilation and are effective insulating barriers year round.

Solar screen materials typically comprise woven fiberglass available in various weave patterns and tightness of weave. The weave pattern and tightness of the weave account for the degree to which solar screen materials are able to act as insulators. Solar screen materials are also available in a variety of colors.

Typically, solar screen materials have not been used for making articles other than those discussed above. Instead, Simon, U.S. Pat. No. 6,497,444 disclosed a typical shielding material for a golf cart application using a woven vinyl-covered fabric made of polyester. Similarly, Randall, U.S. Pat. No. 5,839,462 disclosed a typical shielding material for an extensible and retractable canopy structure for vehicles using a woven vinyl-covered fabric made of polyester. More recently, Teahan, U.S. Pat. No. 6,595,017 and Carter, U.S. Pat. No. 6,158,175 both disclosed a shielding material for shading air conditioning units using a plurality of solar screen materials. However, none of these disclosures have suggested any further applications where solar screen materials may be used.

For the foregoing reasons, there is a need to provide novel articles that make use of solar screen materials and methods thereof.

SUMMARY OF THE INVENTION

Accordingly, it is an object of this invention to provide improved articles having thermal insulation properties that use solar screen materials.

It is a still further object of this invention to provide improved articles having substantially one-way visibility that use solar screen materials.

It is a still further object of this invention to provide methods for using solar screen materials for assembling improved articles having thermal insulation and one-way visibility.
