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.

How do I choose the correct size Glass skylight?

mardome glass measure guide

To suit your own Builders upstand

When Purchasing a Glass unit without un upstand  please ensure the outside edge of your ouw timber upstands are positioned at the same distance as you chosen skylight size. For example if you have a rooflight which measures 900mm x 900mm, you need to ensure the the measurement from the out side edge of your upstand is the same. Please see image for further clarification. A 75mm wide upstand is recommended 

Skylight with UPVc Upstand

When purchasing a  Glass unit with a UPVc upstand the stated sizes represent the opening in the roof. Please ensure the opening in the roof is the same size as the purchased skylight. FOr example if your skylight is 750mm x 750mm the opening in the roof also needs to be 750mm x 750mm.

What is Low-e Solar Glass?

Low e-solar glass has a special coating which reflects heat back to the source. This means your room will stay warm in the winter and cool in the summer

Do I really need Triple Glazing?

On Paper Triple Glazed roof lights are the ideal choice for modern homes and can offer u-values as low as 0.6 W/m²K. However, opinion is divided on whether triple glazing has any real thermal impact in the home. Quite often they do very little to reduce your utility bills and the initial costs far outweigh any savings.

What is a Thermal Break?

A thermal break is a layer of low conductive material placed in the Aluminium frame of a skylight. This stop the internal side of the frame becoming cold and in turn eliminates condensation occurring internally on the frame.

What is the recommended pitch far a Flat Glass skylights?

We recommend a minimum 5 degrees pitch to allow water to run off and prevent pooling on your new skylight. For self cleaning glass to work effectively a minimum 10 degree pitch is recommended. 

This can be achieved by creating a height difference in the installed upstand. Alternatively an Atlas composite upstand can be bought with the pitch already built in. 

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.
