Box Sash Windows

We produce top quality box sash windows (also known as sliding sash) with traditional weights and pulleys.

All of our timber windows and frames are hand crafted in our factory and are made to measure.

We understand that there is no ‘standard size’ when it comes to joinery so we offer a free measuring service, to ensure that we are providing an accurate fit every time. Our variety of window manufacture is vast, so if you are looking for a particular design, or just want to match your existing windows not a problem we will ensure you get the perfect result for your work place or home.

Casement Windows

All of our casement windows are hung on high quality butt hinges in a finish of your choosing. We draught proof the frames of our casement windows to ensure minimal heat loss. We also make flush casement windows with a huge variety of hinge, ironmongery and moulding options.

Madefern Joinery can make your casement windows to match original designs.

For modern buildings we usually recommend storm-proof windows. For older properties flush-casements can be more appropriate. We always pay attention to architectural details like thin wooden glazing-bars, mouldings and window ledges.

In addition to side opening casements, windows can have top-hung opening lights, or pivot openings. Our standard furniture for casement windows is steel/ brass with lockable catches, but we can supply alternatives.
