GE UltraSpan UST-USM Weatherseal

UST2200 transition sheet and USM corners are low modulus pre-cured silicone rubber accessories for flashing and transition applications in the 100% silicone air & water-resistive barrier system by GE.

Silicone Durability - Pre-cured silicone rubber exhibits excellent long-term resistance to natural weathering, including: ultraviolet radiation, high and low temperatures, rain and snow, with negligible change in elasticity.

UV Resistant - May be left exposed indefinitely to UV.

Thermal Stability - Remains elastic over a wide temperature range. Does not harden or become brittle under very cold or wintery conditions and does not soften or melt during high summer heat.

Flexible - Low modulus elastic ruer imparts low strain to movingt substrate surfaces and maintains flexibility at transition areas and board joints.
