Abstract
A method includes obtaining a first membrane; obtaining a second membrane; wherein the first and/or second membrane include an uncured silicone edge portion; installing the first membrane above a roofing substrate; installing the second membrane above the roofing substrate; overlapping the first membrane and the second membrane; curing the uncured silicone edge portion; and providing a lap seal between the first membrane and the second membrane.
Claims20
A system comprising:
- a pre-fabricated first membrane,
- wherein the pre-fabricated first membrane comprises:
- a first layer,
- wherein the first layer comprises a mesh material;
- a second layer,
- wherein the second layer comprises:
- a first portion comprising a cured silicone;
- an edge portion comprising an uncured silicone,
- wherein the edge portion contacts the first layer;
- a pre-fabricated second membrane,
- wherein the pre-fabricated second membrane comprises:
- a cured silicone layer;
- a first layer,
- wherein the first layer comprises a mesh material;
- and
- an uncured silicone layer,
- wherein the first layer is located between the cured silicone layer and the uncured silicone layer;
- wherein the uncured silicone layer is located on an edge portion of the first layer;
- wherein, when installed on a roofing substrate, the pre-fabricated second membrane overlaps the pre-fabricated first membrane such that the uncured silicone layer of the pre-fabricated second membrane contacts the uncured silicone of the pre-fabricated first membrane to form an overlapping portion that cures to form a lap seam.
