Flatglass Skylights
How do I choose the correct size Skyseal Flat Glass Skylight?
To suit your own Builders Upstand
When purchasing a Glass unit without an upstand, please ensure the outside edge of your own 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 outside 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.
How do I measure and choose the right size for my Skyseal Frameless Flat Glass?
Measure the internal hole size in the roof and order the rooflight in that size (e.g. If the hole in the roof is 600 x 600, this is the size rooflight you will need to to order).
What is Low-E soft coat?
Low-E soft coat glass is a type of energy-efficient glazing. "Low-E" stands for "low emissivity," which means the glass has a microscopically thin, transparent coating that reflects heat.
This coating helps keep your home warm during the winter and cool during the summer, improving thermal insulation and reducing energy costs.
What is a Ceramic Border?
A ceramic border blocks UV rays, protecting the seals around the glass from damage and extending their lifespan. By preventing the UV rays from reaching the seals, the ceramic border helps keep them intact and functioning properly for a longer time.
What is an Argon filled cavity?
Argon gas is a better insulator than air. It has a lower thermal conductivity, which means it slows down the transfer of heat through the window. This helps keep heat inside during the winter and outside during the summer, leading to more stable indoor temperatures.
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.
What is a Thermal Break?
A thermal break is a layer of low conductive material placed in the Aluminium frame of a skylight. This stops the internal side of the frame becoming cold and in turn eliminates condensation occurring internally on the frame.
