PatioMaster patio doors are fabricated using a 3 chamber profile for maximum thermal
efficiency and strength.
Our in-house technical team has carried out a series of tests and have confirmed
that the PatioMaster in-line sliding door system is able to comply with the requirements
of Document L of the Building Regulations and the Scottish Building Standards Technical
Handbook Section 6.
These regulations require doors to achieve a U-value of 1.8W/m2K or less in England
and Wales and 1.68W/m2K in Scotland. To find out how the PatioMaster inline sliding
door meets the requirements of Building Regulations please download our guide here.
