Hardwood/Accoya Window Manufacturing Process
- Avoiding Trapped Moisture
Water can penetrate weak points of the external glazing seals. Our products are designed to shed water quickly. This is achieved with a minimum 7 degree slop along side a ventilation and drainage bead to all bottom glazing rebates
- Controlling Timber Movement
All our end grains are coated with an impermeable "end grain sealant" to prevent any moisture absorption
- Complete Finishing process
All our timber products are factory finished using a 3 part water based paint system with a fourth preservative process to meet any class species durability requirement.
- Hardware and Handles
We offer a range of hardware to suit your requirements and our windows can be supplied with traditional monkey tail fasteners (handles) and stays or the latest shoot-bolt locking depending upon your choice. The Dempsy V Flush casement window is a popular choice for the older style of building. The storm-proof range for more modern buildings
