No compromises are made with our construction methods.
Suitable timber is selected and grain matched for appearance. Frame and sash profiles are custom machined to the required specifications. Individual frame components are then joined using a three way mortice and tenon joint that is adhered using waterproof D4, PVA glue.
No mitres, no screws, no rivets and no dowels. Just joinery. The frames are then hydraulically pressed and left to cure. Outside profiling of the sashes then takes place before the windows are machine and hand sanded.
