Manufacturers of uPVC Windows:

Master Plastics SW Ltd manufactures plastic uPVC double glazed windows and doors.


Energy bills are on the increase, environmental concerns are higher on the agenda than ever before and building regulations are becoming more demanding every year. Choosing a window system that offers higher Windows Energy Ratings for a lower cost therefore makes good sense..


With Liniar lead-free, multi-chambered profile, patented co-extruded bubble gasket, glazing flipper and thermal dam, you do not need expensive triple glazing to achieve the highest energy ratings, the Liniar system achieves a WER of A+ with ease and a U-value of 1.2 with cost effective double glazing.


The uPVC profile, or frame, in a Liniar window contains symmetrical chambers to minimise the transfer of heat from the inside of your property to the outside. This, together with other innovative design enhancements, helps to minimise energy costs on an ongoing basis. The Liniar EnergyPlus range contains 6 chambers and can achieve a U-value as low as 0.8 W/m2K.


Unlike other uPVC window systems, Liniar high thermal efficiency hasnt been achieved at the expense of strength or security. The range is accredited with both PAS 24 Enhanced Security and Secured By Design status, assuring you of the highest standards.
