Dualglaze uPVC Sliding Sash Windows

Dualglaze uPVC sash windows have been designed with authenticity in mind. Combining classic looks with modern engineering, our uPVC sash windows will definitely make your property stand out from the crowd.

High Security Features: The cutting - edge design offers strength and security to your sash windows, with an innovative anti jemmy aluminium security bar that prevents the bottom sash from being forced open. Whilst galvanised steel reinforcing creates a rigid, high-strength sash window that's built to last.

Low Maintenance and Stylish Looks: Dualglaze uPVC sash windows are designed for easy maintenance. With inward opening sashes  for safe and easy cleaning from within your home or place  of work and triple seals for exceptional

draft proofing. Decorative sash horns fitted as standard and sculpted internal ovolo bead, means your sash windows not only look great but gives maximum security at the same time.

Thermal and Acoustic Efficiency Guaranteed: An integral overhead vent provides a flow of fresh air all year round, without compromising the security of the sash window. The three chambered profile also offers excellent thermal and acoustic insulation, creating a comfortable environment all year round. As you would expect from Dualglaze products, the Dualglaze uPVC sash window complies with the thermal efficiency requirements of the Building Regulations when used with thermal efficient glass.
