Description
The Tremco Silicone Setting Block – 1/4″ Thick is a high-performance glazing support component engineered to provide proper glass positioning and long-term durability in commercial and residential window systems. Manufactured from premium silicone, this setting block is designed to maintain consistent spacing and load distribution while remaining fully compatible with modern glazing sealants.
Thickness: 1/4 in.
Width: 1-1/8″
Length: 4″
Durometer (Hardness approx.): 80
With an approximate 80 durometer hardness, this silicone setting block delivers the ideal balance of firmness and resilience. The 1/4″ thickness provides increased elevation and support where greater glass clearance or load distribution is required. It helps prevent glass-to-frame contact, maintains proper edge clearance, and resists compression set over time.
Sealed unit window warranties may be voided by the use of rubber setting blocks. Protect your sealed unit warranty by installing silicone setting blocks, which will not react with silicone or urethane sealants commonly used in glazing applications. Silicone remains stable under UV exposure, temperature changes, and long-term environmental conditions.
Suitable for storefront systems, curtain walls, and punched window openings, Tremco Silicone Setting Blocks support professional installation standards and contribute to long-term glazing system performance.
