STRONGLINE window An innovative line of windows that combine the natural qualities of wood and the functional properties resulting from the use of modern solutions. The depth of the frame and sash is 92mm, making Strongline the most stable and durable profile on the market. The heat transfer coefficient of the frame and sash is 1.0 – 1.2 W/m2K. This means excellent thermal protection. The porous structure of the wood and the system of structural notches in the profile structure make the interior of your house perfectly protected against rain, wind, pollution and noise, while maintaining optimal room ventilation. We softened the massive appearance of the Strongline window by giving the window edges rounded shapes and using decorative milling, thanks to which the window looks very solid and elegant.
We offer the option of equipping windows with additional solutions that increase their heat absorption, soundproofing and burglary resistance, as well as beautifying their appearance.
Bertrand uses the most advanced wood varnishes. Our AQUATOP varnish, which we use as standard, protects surfaces from weather conditions and provides them with smooth and long-lasting protection.
AQUATOP is characterized by excellent resistance to moisture. It protects surfaces from water, rain and moisture, preventing problems such as rot, mould and damage that occurs over time. It provides reliable resistance all year round, in any climate.
Thanks to advanced and innovative varnishes and a careful production process, which is a hybrid of automated sanding of flat surfaces and manual sanding of hard-to-reach surfaces such as the surface inside the frame, our wooden windows are characterized by a smooth and flawless finish.
Bertrand wooden windows are perfect for hot climates thanks to the use of varnish with cold pigments.
