Each of our uPVC windows and doors are hand finished using the Liniar profile system. This is a remarkable uPVC profile that offers a wide range of features no other profile available offers. These include unique flipper gaskets to reduce cold transfer, multiple-chambers that break up mini convection currents and positive drainage that is specifically designed to make the most of natural drainage solutions. In addition you will benefit from superior gaskets to maintain very tight weather seals, integrated structures meaning steel reinforcements aren't needed, as well as a thermal dam to reduce any heat transfer.
