Market leading products

Window Supply Company is the largest manufacturer of the most technically advanced Liniar uPVC profile in Scotland. The Liniar profile has been completely designed from scratch to take advantage of the very latest developments in window engineering technology and was the first brand new profile of its kind in the UK in nearly two decades. Liniar’s patented designs were built with the installer in mind, so are simple to fit, saving precious time on the job. View our range of windows and doors here.
