REHAU TOTAL70 UPVC WINDOWS

REHAU Total70 profiles feature an advanced multi-chamber internal design that acts as a thermal barrier, trapping pockets of warm air to drastically cut conductive heat loss. When paired with high-specification double glazing or 44mm triple glazing, U-values as low as 0.8 W/m²K can be achieved—easily exceeding the requirements of UK Building Regulations Part L and helping you substantially reduce household heating bills.

Yes, the REHAU Total70 system is engineered with a 70mm profile depth specifically designed to accommodate high-performance 44mm triple glazing units. This offers exceptional acoustic insulation (up to 45dB noise reduction) and unmatched thermal efficiency, making it the ideal choice for exposed Northumberland locations or properties near busy roads.

Absolutely. All REHAU Total70 windows installed by Northumbrian Windows are internally glazed so the glass cannot be removed from the outside. They are equipped with multi-point shootbolt locking mechanisms, heavy-duty security hinges, and steel reinforcement where required, fully compliant with British Standard PAS 24 and Secured by Design specifications.

Beyond traditional gloss white, REHAU Total70 comes in over 20 durable laminate foil finishes, including popular architectural shades such as Anthracite Grey, Pebble Grey, Slate Grey, and Chartwell Green, as well as authentic timber woodgrains like Irish Oak and Golden Oak. Dual-colour options allow you to choose a distinctive colour for the outside while keeping a clean, neutral white inside.
