3 x 16" Expansion Strip
Polyethylene Foam Strips
Our expansion strips are white Polyethylene Foam pieces that are 3 inches wide and 16 inches in length. They are used in commercial applications along the jambs to allow for expansion and contraction in extreme heat or cold weather conditions. They also help soften the blow as a building naturally settles or shifts. At Quality Glass Block and Window Company, we offer multiple options for glass block designs, styles, shapes and sizes. We offer glass block products that vary by light transmission and levels of transparency so that you can choose the perfect level of privacy. Our experts can help you select the product that is right for you.
