Facts about our German Tilt and Turn Window


How does a standard vinyl (PVC) window compares to a

uPVC window?


PVC (Polyvinyl Chloride) and uPVC (unplasticized Polyvinyl Chloride) are two types of plastic and widely used in the construction industry.

PVC contains chemical compounds to plasticize vinyl including BPA and phthalates (these two chemicals cause harmful effects to the environment and our health, especially in the event of a fire) to give it its flexibility. Therefore, it is more porous and requires more maintenance. 

uPVC is unplasticized polyvinyl chloride and does not contain BPA or phthalates. uPVC is a robust material especially in the construction industry due to its thermal efficiency and durability. uPVC does not flex, has a higher impact resistance, is fire-resistant and is a recyclable material.

How does a Tilt & Turn window compares to a sliding or casement window?


A dual action window (tilt & turn window) swings and tilts to the inside of the room.

The turn position swings the operating sash to the inside of the room, depending on which side the hinges are located. The tilt position opens the window only at the top due to the hardware mechanism. This provides you with an increased air exchange and better air circulation while used and warm air is always traveling upwards and can escape through the open tilt position. A great advantage is that our tilt & turn windows make it easy and safe to clean then inside and outside. 

Why do you need a multipoint locking system even on your smallest window?


Even our standard basement egress tilt & turn windows (1000mm x 600mm) have multiple locking points in the frame plus two hinges, one at the top and one at the bottom. This well designed hardware mechanism will provide you with a tremendously increased level of security to protect your property at any time. 

How about adjustments on your new windows?


Every operating sash is 360 degrees adjustable to maintain a flawless operation at all times. This great feature would not be possible with a North American manufactured sliding or casement windows, but is often required in homes.

What is the difference when it comes to glass options?


The most common glass thickness for each individual glass pane in North America is typically 3mm. We are using a minimum of 4mm thick glass or even thicker for each pane. Adding a LowE or ClimaGuard coating to increase solar heat transmission and adding argon or krypton gas to your insulated glass unit slows down the heat exchange process as much as possible.

Thicker glass also decreases your level of acoustic transmission to block out unwanted noise from the outside.

Be sure

Our windows are tested and approved according to the NAFS - AAMA/WDMA/CSA

101/I. S. 2. / A440- 11/17 standards and CSA A440 S 1-17 Canadian Supplement.

Not only did we pass all required testing, but exceeded even our expectations. 

For example, in 1934 in Mount Washington, New Hampshire was the highest wind speed ever measured on earth at 231 miles per hour (mph), which translates to 371.758 kilometer per hour (km/h).

Our windows (depending on the configuration) withheld approximately 6000 pascal -  

360 km/h which is an outstanding result and proves superior performance.

To compare this, a catastrophic hurricane is rated at 157+ km/h wind speed.
