Our uPVC couplers are necessary when two frames need to be neatly joined together. It is important to remember that if you are ordering a uPVC coupler, you should reduce the width of the shortest window by 5mm to allow for it, as we will not make this allowance.
uPVC extensions are used to thicken the frame. Available in 15mm, 25mm and 40mm thicknesses, you must ensure that you make appropriate reductions when ordering your window/door, as again, we will not make this allowance.
We pride ourselves on the quality of our products, which are designed, manufactured and sold directly with us.
