STRONGLINE window. An innovative line of windows that combines the natural qualities of wood and functional properties coming from the use of modern solutions. The depth of the casing and sash is 3 5/8 in (metric – 92 mm) , which makes Strongline the most stable and durable profile on the market. The heat transfer coefficient of the casing and sash amounts to 0.1762 – 0,2115 U Factor (summer) IP from: 0.1762 – 0,2115 Btu/hft2F U Factor (metric) IP from: 1,0 – 1,2 W/m2K. This means absolutely superior thermal protection. The porous structure of the wood and the system of structural grooves in the profile ensure that the interior of your home is perfectly protected against rain, wind, pollution and noise, while maintaining optimal ventilation of the rooms. The massive appearance of a Strongline window we have softened by rounding the window’s edges and introducing the decorative cutters, thanks to which the window looks very solid, yet elegant.
We offer the possibility to equip the windows with additional accessories which will improve its heat-absorption, sound-proof properties and the burglary resistance, as well as its beauty.
The Strongline system windows are available in two versions:
Master and Retro
on the outer edge of the sash we placed an additional aluminium cover, which protects this part of the window from the solar radiation and rainwater.
