At Warmseal, your security is our main priority. That’s why all of our doors and windows are subject to vigorous safety standards, and we’re always innovating new ways to keep our customers as safe as possible.

If you’re looking to keep your family protected once you lock your doors and windows at night then you won’t find better installations than the ones provided by Warmseal!

The Highest Security StandardsKitemark

We want you to feel confident in your decision to choose Warmseal for all of your installation needs. All of our windows are Kitemarked to BS 7412, BS 7950 and all of our doors are Kitemarked to BS P.A.S. 24. These standards will provide you with enhanced security, as will the British Standards Institution 7950 logo which is carried by all of our windows.

To give you even more peace of mind, once we’ve installed your new windows, doors or conservatory we will write to you so that you have a record confirming that all of our vigorous safety standards have been met within your installation.

Finally, all of our Warmseal windows are installed in accordance with the Glass and Glazing Federation (GGF) code of practice for the installation of PVCu windows. We choose to follow the guidelines laid out by the GGF because we want you to feel confident in the quality of the installation we offer.

Police Force RecommendedSBD

House burglaries are on the decline in the North East, with recent figures showing that house burglaries have decreased by 6%: that puts them at their lowest rate since 1981. The Police forces in Northumberland are determined to build on these results by urging homeowners who are thinking of adding double-glazed windows or doors to their properties to choose products that carry the Secured by Design logo and are Kitemarked or BBA certified.

You’ll find both of these high safety standards within the Warmseal product range.

Warmseal are proud to provide to be one of only a very few companies that have achieved Secured by Design accreditation. That means that you can pick any door or window from our wide and varied range with confidence, knowing that you’ll never have to sacrifice style for security.

If you have any further questions or queries about the security standards of any of our high quality products then why not contact a member of our expert sales team? They’ll be happy to discuss the security accreditations of all of our products with you, because the satisfaction of our customers is vital to us.
