What silicone should I use for frameless rooflight installation?

When it comes to fitting frameless rooflights, it is essential to use high-quality sealants that provide reliable weatherproofing and structural integrity. That's why we recommend using Dowsil 791 Low Modulus Weather Proofing Silicone and Dowsil 895 Structural Sealant.

Dowsil 791 Low Modulus Weather Proofing Silicone is specifically designed to create a durable and flexible seal that can withstand extreme weather conditions. It offers excellent adhesion to a wide range of substrates, including glass, aluminum, and PVCu. This silicone sealant provides long-lasting protection against water ingress, ensuring that your frameless rooflight remains watertight and leak-free.

Dowsil 791 and Dowsil 895 Silicone is compatible with Dowsil 3363, the silicone used in the production of our frameless rooflights. This compatibility is crucial to prevent any chemical reactions between the two silicone materials during installation, ensuring the integrity of the seal and avoiding any potential damage or compromise to the rooflight.

For structural bonding and enhanced strength, we recommend using Dowsil 895 Structural Sealant. This high-performance sealant is specifically formulated to provide exceptional adhesion and structural stability. It is ideal for bonding glass and other construction materials, making it perfect for securing frameless rooflights in place.

By using Dowsil 895 Structural Sealant, you can have peace of mind knowing that your frameless rooflight is securely installed and can withstand the test of time. Its excellent resistance to UV radiation, weathering, and temperature variations ensures long-term durability and performance.

When fitting frameless rooflights, it is crucial to prioritize the quality and compatibility of the sealants used. By choosing Dowsil 791 Low Modulus Weather Proofing Silicone and Dowsil 895 Structural Sealant, you can ensure a reliable and long-lasting installation that will enhance the aesthetic appeal of your space while providing ample natural light.
