At Greenleafjoinery we offer ‘Seamless door’ solutions where new technologies are applied in manufacturing traditional and contemporary internal and external doors. Our ‘Seamless door’ technology means traditional seams between stiles and rails are avoided during manufacture thus making the doors much more durable against cracking, swelling or bowing.
‘Seamless door’ inner frame is made of engineered Karelian pine or hardwood as an option. We apply high standard quality requirements to the timber. It has to be free of knots, resin pockets, splits or cracks. The timber is dried at modern kiln drying systems up to 8% (±2%) moisture content. Several layers of timber are then glued together in vertical or semi-vertical grain, with the middle parts in random grain with micro-porous adhesives. This type of triple layer wood engineering prevents swelling or distortion of the woodwork in the future. Raised, flat or moulded panels can be made using solid wood, plywood, chipboard or mdf core. The finishing layer allows for smooth seamless surface which can be painted or veneered.
Most common and not only glass types such as safety, obscured, tinted, etc. can be used in accordance to a client’s needs. Our external doors can be fitted with double glazed 24mm (4-16-4) argon gas filled K-glass units providing thermal properties of 1.1W/m2K.
All external doors are fitted with weather seals for ensuring maximum weather tightness. Internal doors can be fitted with 10mm or 20mm intumescent strips upon request.
Thermal transmittance of our external doors is 1.5 W/(m2-K) test method ref. nr. EN ISO 12567-1.
We can offer you a wide variety of top class ironmongery from an extensive range of the best UK suppliers we work with.
All new doors can be factory spray finished with two primers and two topcoats in RAL 9010 color. Veneered surfaces can be factory varnished, painted or oil finished.
