Semi-rigid Polyurethane foam featuring open-cell structure which allows air and moisture to reach the silicone for optimum curing.   It also provides long-term resistance to loading and is resistant to environmental influences which enables the longevity of structural silicone glazed systems in the field.

Polyurethane Spacer Tapes can withstand environmental stressors and perform under pressure, making them the ideal solution for structural silicone glazing applications. This is due to excellence in load deformation performance and water vapour transmission rate (WVTR).
