Thermally efficient

Our slimline aluminium windows offer optimal thermal efficiency, achieving U-values as low as 1.2 W/m²K for a triple glazed aluminium window with a thermally broken frame.

High security

Slimline aluminium windows are highly secure, with toughened safety glass and multi-point locking systems. Additionally, they are PAS 24 certified and Secured by Design accredited.

Long-lasting

We exclusively use top-quality aluminium, which makes our windows strong and durable for decades. Aluminium can withstand pressure, harsh weather conditions and damage.
