high performance sliding/folding doors.
CAN YOU EXPLAIN WHAT THERMAL VALUES ARE? A U-value measures heat loss, so the low- er the U-value, the less heat lost.

The G-value, is also important, which is the measure of how much solar heat and
Always ask your supplier for weather testing reports. High quality doors will always have extensive weather testing and will be of a superior quality. How much your house is exposed to weather can be a real factor here in determining your choice. If you’re in a very exposed area then it’s advisable to go for a low maintenance material with good Pascal (air permeability) ratings. With regards to the outside it’s always best to have a small gap between the paving or decking to allow for water to
drain away from the doors into a drain under the eternal oor. ts also est practice to have the eternal oor ust slightly lower than the internal, to negate any risk of water ingress. A reputable company should be able to provide details of this and show you exactly how to achieve the desired effect.
