Warm-edge window spacers are critical to improving insulated glass units' insulation performance and energy savings. Our ultra-high barrier window spacer laminates are designed to ensure effective warm-edge window spacer performance by ensuring that moisture won't permeate in and insulating gas won't permeate out. They provide negligible thermal bridges compared to aluminum or stainless steel foil laminates and have very high corrosion resistance.

We offer films in thicknesses of 20 to 48 microns, with barrier levels ranging from medium to ultra-high. Our films are available with proprietary surface treatments that ensure compatibility with industry sealants and spacers used for insulated glass unit production.
