This insulation creates an air seal to your building or structure and offers many benefits. Screening spline reduces air flow that also stops cold to get through, provides great sound control, and deters the growth of mold and mildew. More importantly, it also has the ability to resist heat transfer in or out of a space, keeping it cool during summer and warm during winter. Unlike traditional insulation material, such as fiberglass or cellulose, polyethylene foam screening spline works like a windbreaker that’s much more effective in insulating a space or equipment. It also works great in residential buildings and significantly contributes to lower energy bills.
Screening spline comes in two types: open cell and closed cell foam structure. These two differs significantly when it comes to performance. On one hand, open cell foam is pliable and very light because of its construction. Since it has an open cell structure, when wet the gas trapped inside can escape through the opening of the cell’s wall as the foam dries. As a result, the insulation material can shift as it settles back to its original form. On the other hand, the closed cell foam is heavier and denser, making it more resistant to moisture, temperature change, and weathering.
