Proven Performance and Design:

A revolutionary process that laminates six components of specialized functions to create a composite structure. The Dura Platform is comprised of both Duraseal and Duralite offering window manufacturers two options of warm-edge technology each with its own unique performance attributes. Duraseal can often be more cost effective while still offering superior thermal efficiency. Duralite is the most thermally efficient spacer because it contains NO METAL making it the best warm edge system on the market today.
