Why Is An Aluminium Frame Important?

Added Structural Strength

Our highly-developed Aluminium frame provides extra strength and rigidity, minimising structural movement in the skylight once installed, which significantly reduces the chances of failure.

Extra Damage Protection

The aluminium frame acts as a protective layer, encapsulating the glass at its weakest points to prevent accidental damage that would otherwise shatter the glass.

Enhanced Home Security

Using tamper-proof fixings and not just silicone sealant helps keep your home secure. Our skylights are accredited by Secure by Design (police preferred specification).

Extra Glass Support

The frame is key in providing extra support to the glass, ensuring the glass stays in place in the event of damage or shattering.

Questions & Answers (1)

What is a U-value?

Thermal transmittance, also known as U-value, is a measure of heat loss through the structure. It is measured in W/m2K. The lower the value, the better the insulation.

The UK Building Regulations require a maximum of 2.2 W/m2K in existing dwellings and an average of 1.2 - 1.7 W/m2K for new dwellings on rooflights.
