Durometer (Hardness approx.): 80
Manufactured from high-quality silicone, this setting block provides durable, long-term support in commercial and residential glazing applications. With an approximate 80 durometer hardness, it offers the ideal balance of firmness and resilience to evenly distribute glass weight while resisting compression set over time.
Sealed unit window warranties may be voided by the use of rubber setting blocks. To help protect your sealed unit warranty, install silicone setting blocks, which will not react with silicone or urethane sealants commonly used in glazing systems. Silicone material remains stable under UV exposure, temperature fluctuations, and prolonged environmental conditions.
These setting blocks are suitable for storefront systems, curtain walls, punched window openings, and other high-performance glazing assemblies where proper edge clearance and compatibility with sealants are essential.
