The Demsun Multi-Purpose Building Neutral Silicone N27 is a trade-essential sealant designed for a vast array of construction and glazing applications. Unlike acetoxy silicones, N27 releases an alcohol-based vapour during curing, making it virtually odourless and safe for use in confined spaces. At ECO Heat Shop, we provide the robust hardware and sealing solutions required to maintain a weather-tight building envelope in the demanding UK climate.
Demsun N27 is particularly favoured for window and door installations due to its superior primerless adhesion to PVCu, treated timber, and powder-coated aluminium. Its chemically neutral formulation also makes it a “problem-solver” for expansion joints in concrete and brickwork where a non-staining, flexible seal is required. Whether you are working on a new-build project or performing essential home maintenance, N27 delivers a professional, shrink-proof finish every time.
ECO Heat Shop Tip: For a sustainable and energy-efficient home, use N27 to seal the external perimeter of your window frames. This prevents heat loss and moisture ingress, significantly improving the thermal performance of your property. For the best aesthetic result, use a joint finishing tool to press the silicone into the gap, ensuring 100% contact with the edges.
The professional’s choice for a non-corrosive finish. Order Demsun Multi-Purpose Building Neutral Silicone N27 online today for high-grade construction hardware delivered across the UK.
