  • The Perfect uPVC Profile

    The Perfect Profile

    Liniar have designed the perfect uPVC profile which is why we are confident you will love your new installation by Altex. It offers superior design features and a technically advanced uPVC window system that is unrivalled by any competitor.

    What Makes Our uPVC So Special?

    There are six key features that make a Liniar profile stand out from the crowd. Flipper gaskets are in place to effectively reduce the amount of cold and damp entering your property. Each profile has six-chambers in order to lock in additional pockets of warm air. Double action ‘bubble’ gaskets make sure each window and door in Essex is tightly weather sealed. The uPVC material used is particularly rigid in order to cut out the use of steel reinforcements.

    Hand Finished uPVC Products

    All our Liniar products are lovingly crafted and finished by hand to ensure complete perfection in every order. There are four steps to the hand finishing process.

    1. Using precision chisels for a completely smooth finish, all the corner contours are meticulously checked for appearance and detail.
    2. Using engineered contour blocks the outside edges can be levelled at the corners which create a beautifully square silhouette when hung.
    3. For exactitude and uniformity every corner groove is looked over to ensure an even depth is in place which can be manually deepened if found too shallow.
    4. All apertures are examined for weld build-up in the corners and carefully removed to guarantee a tight weather seal.
