Passive/Energy Efficient Windows

• Certified U-values of 1.1 W/m2K to 0.7 W/m2K for triple glazed windows, ideal for meeting Passivhaus standards.
• Security – Russell Timber Technology windows and doors are tested to the requirements of Secured by Design – PAS 24:2022.
• Acoustics – Russell Timber’s Premium Performance Acoustic range provides outstanding acoustic properties and can be configured to achieve noise reduction of up to 58db at a U-value of 1.2 W/m²K for timber or alu-clad. Includes a full range of top and side hung Fully Reversible windows and Tilt & Turn windows.
• Products have been tested for Air Permeability, Water Tightness and Wind Resistance, plus resistance to racking, static torsion, repeated opening and closing, and to load bearing capacity of safety devices and operating forces.
• All fully reversible windows use the Spilka hinge, which has undergone extreme testing by Spilka. It is a high quality, durable, and secure component with a smooth operating system.
• Warm Edge – The energy efficiency of our range of windows is boosted by Warm Edge Technology from Super Spacer and Swisspacer. Warm edge spacer bars improve the life span of the glazing unit by reducing the risk of cold bridging through the glass unit and thus condensation.
• Every door and window and every component in them is uniquely coded and logged on our Total Traceability Database – a detailed database showing exactly where every one of your doors and windows has been installed, even if you choose to install them yourself.
