ST70 HI Tilt & Turn Window

The ST70 HI inward opening tilt & turn window system has recently been updated with enhanced thermal performances. Our design team have improved this system by including new eco-friendly polyamides and new foam cores producing a whole window Uw value as low as 0.98W/m²K.

The tilt and turn system is a great solution to areas of a facade that require ease of access for cleaning or maintenance. The windows durability and performance characteristics, with regard to acoustics and weather tightness, meet with the highest BS/EN standards and are all independently tested by a UKAS approved and certified facility.

With a glazing variant of 28-42 mm, the ST70 HI high-performance window range is an eco-friendly, cost-efficient option suitable for all types of construction from commercial to residential. It would be perfectly suited for student accommodation developments.
