Windows STRONGLINE<\/strong> is an innovative line of products that harmoniously combine the natural values of wood with modern technological solutions. Thanks to this, these windows are not only aesthetic, but also extremely functional.<\/p>\n

 <\/p>\n

Unique Design for Ultimate Stability<\/h4>\n

 <\/p>\n

The frame and sash depth of 92 mm makes STRONGLINE the most stable and durable profile available on the market. The heat transfer coefficient guarantees excellent thermal insulation, so your home will be warm even in the harshest winters.<\/p>\n

The porous structure of the wood and the system of structural notches provide not only protection against rain, wind and noise, but also an effective barrier against pollution. At the same time, these windows allow for maintaining optimal ventilation, which translates into a healthy microclimate inside the rooms.<\/p>\n

 <\/p>\n

Solidity and Elegance in One<\/h4>\n

 <\/p>\n

The characteristic, massive appearance of the windows has been subtly softened by rounded edges and decorative millings. Thanks to this, the windows look elegant and harmonious in any interior. Natural wood gives them warmth and a unique character, ideal for both classic and modern arrangements.<\/p>\n

 <\/p>\n

Possibility of personalization<\/h4>\n

 <\/p>\n

Windows can be equipped with additional solutions that increase their heat absorption, sound insulation and resistance to burglary. There are also personalization options that allow you to adjust the appearance of windows to individual needs.<\/p>\n

<\/h4>\n

Bet on STRONGLINE<\/h4>\n

 <\/p>\n

STRONGLINE are windows for people who are looking for reliable, durable and aesthetic solutions. By investing in this line, you choose quality, energy efficiency and style. It is a perfect combination of wood tradition with modern technology.<\/p>\n

 <\/p>\n

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.<\/em><\/p>\n

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.\u00a0<\/em><\/p>\n

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.<\/em><\/p>\n

Bertrand wooden windows are perfect for hot climates thanks to the use of varnish with cold pigments.<\/em><\/p>\n
