Retrofit Sills Ltd. is a member of the Neustone group of companies.
Retrofit Sills Ltd. provide superior quality insulated window sills for the construction industry. We supply oversills for the EWI market and new build sills for both the UK and Ireland.
Our window sills are light-weight, durable and eliminate cold-bridging. They can be retrofitted to existing window sills making them the ideal choice for external insulation contractors, or can be used in new builds.
The sills are easily customised and very easy to install (see our Installation Guide for more details) and can be fitted to the most awkward windows.
Our products will shortly have full BBA certification for the UK and NSAI for Ireland.
