Lyn Poole, Development Officer for Secured by Design, comments: “Masterframe Windows Ltd has been a valued SBD member since 2009. I am so pleased that even in these challenging times they have renewed their SBD licensed membership, it’s good to know that they feel and understand the benefits for a company such as theirs and reap rewards from the SBD brand”.

Carol Slade, Managing Director for Masterframe Windows, said: “We are committed to supplying the best quality sash windows possible, and so it is very important for us to include this accreditation with our products because the principles of Secured by Design have been proven to reduce crime.

We care about the safety of customers and their possessions and added security  is achieved by fully reinforcing our sashes with steel, using robust furniture and reinforced finger latches and then having them independently tested by SBD, ensuring that our windows are as secure as we claim them to be.  SBD is the only way for companies to obtain police recognition for security-related products in the UK.”

Carol continues “If you or your customer is investing in sash windows from Masterframe Windows, you can rest assured that as specialists, we will have looked at every minute detail that can improve not only the security of our windows but also the longevity and performance.
