TW70 TruEnergy Commercial Window

The TW70 TruEnergy Window offers true energy efficiency, easy fabrication and PAS 24 security. It’s ideal for use in commercial, light commercial and domestic applications.

The TW70 aluminium window system has been engineered so that thermal breaks are positioned in the most efficient way. Thermal infills are easily slid into the aluminium window profile to achieve U-Values of 1.4 W/m2K with a double-glazed unit. U-Values of 1.2 W/m2K can be achieved with triple-glazing.

To help fabricators and installers achieve security levels specified by architects and developers, the TW70 window has PAS 24 accreditation on all of its window variations: Top Hung, Side Hung, Tilt and Turn. Test reports are available upon request.

The system is fully compatible with PVCu hardware, so fabricators don’t need to hold double hardware stocks.

Dependent on your preference, the TW70 window system has been designed to be fabricated in two ways. It can be crimped or fabricated with mechanical Monticelli cleats. Machinery is also available to assist in window preparation and the window is fully compliant with Document L 2016.
