Frequently Asked Questions
What is a tilt and turn window?
A tilt and turn window is a window which provides multiple opening configurations by opening and tilting inwards. This feature allows for easy access to clean the window, excellent air circulation during hotter weather conditions and increased safety.
Do aluminium windows offer any advantages?
Aluminium windows typically have a longer lifespan, meaning you could save money on replacements. To save on energy costs, our Smart aluminium windows have thermal break technology to create a barrier between the cold outside climate and the warm air inside.
