Technical details of our Slimline uPVC Casement Windows

Did you know…

  • Windows account for up to 30% of your home’s total heat loss, contributing to increasing energy fuel costs. Which is why it is important for you to choose an energy-efficient double glazed window.
  • The minimum “Window Energy Rating” (WER) required of all windows, in accordance with current legislation, at this time is a ‘C’. Each WER rating (A, B & C) has varying degrees of standards.
  • These variances are highlighted by testing authorities providing tested windows with an Energy Index. The higher the Energy Index number, the more efficient the window is at retaining generated heat.

Our exclusive Slimline Window

  • The Sheerwater Glass Slimline Window has undergone vigorous testing by ‘BFRC’. Awarding our window with an Energy Index of +11. This proves how energy efficient the Sheerwater Glass Slimline Window is in comparison to other leading brands.

Security

  • Security is of great importance to you, your home and your family. So rest assured in the knowledge that Sheerwater Glass Slimline Windows are fitted with Trojan multi-point, shootbolt locking mechanisms. We are very proud to announce that this locking mechanism has achieved a BS7950 status.
  • Our Slimline Windows are also fitted with security glazing to prevent the intact removal of glass units, along with hinge protection, as standard features of the product. Nothing is impregnable but our Slimline Window has foiled all attempts of forced entry (excluding the breakage of glass) that we are aware of to date.
