Glazing & Roofing Silicon

About Our Glazing & Roofing Silicone

Our glazing silicone and roof silicone range has been carefully selected to deliver superior sealing and durability in demanding environments. Whether you’re fitting glass panels, repairing roof tiles, or sealing gutters, every product provides strong adhesion, weather resistance, and flexibility for long-term results.

For glazing projects, we stock silicone for glazing that remains permanently flexible while providing an airtight, watertight bond between glass and frame. These sealants are non-corrosive, making them ideal for aluminium, uPVC, and timber window systems. They’re also resistant to UV, moisture, and temperature changes — ensuring that your windows stay sealed and condensation-free.

When it comes to roofing, our roof silicone sealant options are designed to tackle leaks and weather damage. Perfect for flashings, joints, vents, and skylights, they form a durable, waterproof barrier that expands and contracts with your roof. Whether you’re sealing a conservatory roof or patching up small cracks, you’ll find a solution that’s easy to apply and built to last.

Choosing the Right Silicone for Your Job

Picking the correct glazing silicone sealant or silicone roof sealant depends on the materials you’re working with and the level of exposure to moisture and temperature. For window and door applications, opt for a neutral-cure silicone for glazing – this prevents corrosion on metal frames and provides a strong, flexible seal on glass and uPVC. For bathrooms or kitchens, an acetoxy-cure variant may be preferred for its fast setting and mildew resistance.

If your project involves roof repairs, look for roof sealing silicone that’s specifically rated for outdoor use. These sealants are UV-resistant, waterproof, and capable of withstanding extreme weather conditions. They adhere to a range of materials, including lead, asphalt, slate, and felt, making them a versatile solution for general roof maintenance.

Our collection also includes multipurpose roof silicone suitable for sealing joints, fixing leaks, and bonding roof components. These high-performance sealants are easy to apply using a standard caulking gun, allowing for a clean, professional finish whether you’re tackling a large job or a quick repair.
