PolyTech windows and doors offer you a European design that has proven iteself for over forty years. We have been making windows with quality PVC - the first in Europe with vinyl - since 1966, and we have been manufacturing windows at our Baddeck, Nova Scotia factory since 1988. The Tilt-and-Turn style of windows open in at the top for ventilation (tilt), and also open at the side like a door (turn), for maximum cleaning, ventilation, or in case of fire, quick and easy escape exit (egress). All these operations are performed by one handle for your complete convenience. The sash and frame are double weather-stripped, with compression seals and a multi-point locking system all around the sash opening for maximum protection against the outside elements. The sash and frame are also steel reinforced, according to size. This means PolyTech windows are among the strongest on the market, with the highest test results for air infiltration, water leakage, and wind load pressure. Because the entire sash opens in, a smaller window will pass egress codes for bedroom windows for fire escape purposes.
