Abstract

Official abstract text for this publication.

A method for covering a roof, the method comprising (i) providing first and second silicone membranes, where the membranes are in the form of rolls; (ii) unrolling the first and second silicone membranes over a roof surface; (iii) positioning first and second membranes adjacent to one another and overlapping and edge of the second over an adjacent edge of the first membrane to thereby form a lap; (iv) securing the first and second membranes to the roof surface; and (v) seaming the first membrane to the second membrane in the lap.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for covering a roof, the method comprising: (i) providing first and second silicone membranes; where the first and second silicone membranes are prepared from curable compositions that include a gum-based silicone rubber, a hydroxyl-terminated or vinyl-terminated polysiloxane plasticizer, fumed silica, and a reflective pigment; and where the first and second silicone membranes are in the form of rolls; (ii) unrolling the first and second silicone membranes over a roof surface; (iii) positioning the first and second silicone membranes adjacent to one another and overlapping an edge of the second silicone membrane over an adjacent edge of the first silicone membrane to thereby form a lap; (iv) securing the first and second silicone membranes to the roof surface; and (v) seaming the first silicone membrane to the second silicone membrane in the lap. 2. The method of claim 1 , where said step of securing includes mechanically fastening the first and second silicone membranes to the roof surface. 3. The method of claim 1 , where said step of securing includes adhesively securing the first and second silicone membranes to the roof surface. 4. The method of claim 1 , where said step of seaming the first silicone membrane to the second silicone membrane includes adhesively seaming the first and second silicone membranes. 5. The method of claim 1 , where the first and second silicone membranes are characterized by tensile strength of 100 psi to 2,000 psi as measured according to ASTM D412. 6. The method of claim 5 , where the first and second silicone membranes are characterized by elongation at break of 50% to 400% as measured according to ASTM D412. 7. The method of claim 6 , where the first and second silicone membranes are characterized by a reflectivity of 13% or greater wherein the reflectivity is measured after 3 months of exterior exposure and where the reflectivity is measured using a spectrometer at 380 nanometers. 8. The method of claim 7 , where the first and second silicone membranes are characterized by a reflectivity of 20% or greater wherein the reflectivity is measured after 3 months of exterior exposure and where the reflectivity is measured using a spectrometer at 380 nanometers. 9. The method of claim 1 , where said step of unrolling includes unrolling the first and second silicone membranes over an insulation panel.
