Tilt & Turn Windows

Aluminium Tilt & Turn Windows for Trade Supply

Evaframe supplies the Cortizo COR 70 Hidden Sash aluminium tilt & turn windows to installers and builders in South Wales and South West England. This innovative system combines slim sightlines with the practicality of a tilt and turn opening, giving your customers a stylish, secure, and highly functional choice.

Versatile Design and Easy Operation

The tilt and turn function lets the sash open in two ways. In tilt mode, it provides safe and secure ventilation without fully opening. In turn mode, it swings inward for easy cleaning and maximum airflow. As a result, this design works well for both homes and commercial spaces. It is especially useful where access and maintenance need to be simple.

High Performance and Thermal Efficiency

The COR 70 Hidden Sash system features a 70 mm frame depth, advanced thermal break technology, and a triple EPDM gasket. This combination achieves U-values from 1.0 W/m²K. In addition, it supports glazing up to 40 mm and provides acoustic insulation of up to 46 dB.

It has been tested to Class 4 air permeability, Class E1650 water tightness, and Class C5 wind resistance. The window also passes strict security tests. Therefore, you can offer your customers a safe, energy-efficient, and durable solution.
