Aluminium casement windows and doors with in swing panes as certificates window sub frame top head

Tilt Turn window is a European-style window with two distinct functions: swing it in like a door or tilt the top of the sash into your room for ventilation. Tilt-turn windows are three windows in one handle control. Depending on the handle position, they can be operated as a fixed window (handle in 6 o'clock position), inward casement window (handle in 9 o'clock position) or hopper window (handle in 12 o'clock position).

Here is Doorwin’s latest Tilt Turn Window. Which is Interior Solid wood and Exterior Aluminum Cladding. Timber is the preferred choice to be window frame because of its perfect heat transfer efficient. Our aluminum- clad frame is the upgraded ones. While timber performs better on energy efficient and cost less, but exterior timber side may rot, warp, peel or rust when they are installed in adverse weather condition, in normal weather condition , exterior timber side will last 10-15 year’s without any damage based on our timber treat technique. I’d like to show our aluminum- clad wood frame, timber part thickness options we offer 68mm(2.67in) 78mm(3.07in) , with aluminum cladding thickness is 20mm(0.79in) , this type frame brings elegant wood type looking interior and strong structure exterior. This window system caters for the whole market with enhanced security options by design and many optional accessories for safety and comfort. Good weather proofing can be achieved as it is fitted with a continuous seal around the internal side of the sash or frame. 4 Layers Sealing rubber strip could guarantee that Air-Tightness is perfect. The Whole Window Applied Equal Pressure Cavity Drainage Design, and make sure No Water Penetration During the Strong Wind and Heavy Rain.
