Cavity Wall Construction

Passive Sills window sills are designed to work with cavity wall construction and are installed in the same way as a traditional concrete sill.

For the majority of cavity wall construction projects our P1 window sill – 250mm deep with a 50mm upstand – is ideal.

Our sills have excellent insulation value, this improves the overall insulation value of a building by reducing the cold bridging at the point where the sill and window meet

The Passive sills P1 sill is 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.
