Solid Block Construction

These sills are designed to work with solid masonry construction with 200 mm external insulation and are installed in the same way as a traditional concrete sill.

Our passive window sills have an excellent insulation value, this improves the value by reducing the cold bridging at this point. It also improves the overall performance of your window.

Our passive window sills are approximately 10% of the weight of a traditional concrete or stone sill and reduces the risk of manual handling injuries on site.

Our window sills are available in our hybrid finish, which has a white paint primer coat and is ready to be painted any colour you choose.
