A self-adhering roofing membrane may include a polymeric membrane. The roofing membrane may include a first adhesive layer disposed on a major surface of the polymeric membrane. The first adhesive layer may include one or both of a hot melt adhesive and a butyl rubber-based adhesive. The roofing membrane may include a UV curable adhesive layer disposed on the first adhesive layer. The UV curable adhesive layer may have a thickness of less than about 4 mils.

Double pass process of making a self adhering roofing membrane with improved adhesion at lower installation temperature

A roofing membrane may include a main body, a first material, and a second material. The first material may be bonded to the main body and positioned toward a first edge thereof. The second material may be bonded to the main body and positioned toward a second edge thereof. The second edge may be positioned opposite the first edge such that the first and second materials are positioned toward opposite edges of the main body. At least one of the first material or the second material may include a first reactive material of a chemically reactive two-part cure system that is configured to chemically react upon contact of the first reactive material with a second reactive material of the chemically reactive two-part cure system.

Roofing membranes having multiple adhesive regions and method therefor

Thin film photovoltaic devices that include at least one lead bar extending through a connection aperture defined in the encapsulation substrate are provided. The photovoltaic device can include: a transparent substrate; a plurality of photovoltaic cells on the transparent substrate; a first conductive ribbon electrically connected to a first photovoltaic cell; an encapsulation substrate laminated to the transparent substrate such that the plurality of photovoltaic cells and the conductive ribbon are positioned between the transparent substrate and the encapsulation substrate; and, a first lead bar extending through a first connection aperture defined in the encapsulation substrate. The first lead bar is electrically connected to the first conductive ribbon. For example, a meltable conductive material can be connected to the first lead bar and to the first conductive ribbon to establish an electrical connection therebetween. Methods are also provided for electrically connecting a lead to a thin film photovoltaic device.
