Frequently Asked Questions.

Here are answers to some Frequently Asked Questions.

What colours are your products available in?

Our standard colours are Black, White and Anthracite grey however, we can offer any colour which has a RAL code, a range of textured colours which are harder wearing as well as dual colour options allowing you to have a different colour on the inside of your door to the outside of the door.

By having such a large colour range, it really makes it possible for our clients to fully customise the door to exactly what they would like for their home.

  • Roof lights take 4 weeks

  • All other products are 5-7 weeks.

What is a U-Value

Thermal transmittance, also known as U-value, is the rate of transfer of heat through a structure (such as a glazed unit or a full door system), divided by the difference in temperature across that structure.

The units of measurement are W/m²K. The better-insulated a structure is, the lower the U-value will be. U-value of our products depends on the glass we use so if you have a certain U-Value you need to meet in your home let us know and we will discuss your glass options.
