Prefabricated dormer
Ready-made solutions for increasing space and natural light in attics.





More natural light in your attic
Prefabricated dormers increase daylighting in a way that cannot be achieved with standard single roof windows. You gain space where light is distributed evenly thanks to sets of windows arranged in two or three rows. Glazed surfaces create a bright, pleasant interior, and advanced glazing units reduce heat loss, maintaining stable conditions year-round.
More space thanks to modified roof geometry
The prefabricated dormer structure extends beyond the roofline, which effectively increases the usable space of the room. You gain space that may have previously been difficult to access or completely unusable. The stable, insulated base supports the partition's thermal insulation, ensuring the interior remains functional both in winter and summer. This extension allows for the creation of space for a desk, a relaxation area or full-size furniture – without the compromises involving a sloping roofline.
Designed to operate in demanding conditions
The dormer is constructed as a complete module, with each element – from the insulated base to the glazed segments – adapted to the specific roof pitch. The resulting structure is resistant to wind, rain, and temperature fluctuations, thanks to increased-strength glazing units and stable frames. Prefabrication eliminates the risk of installation errors, as each module is manufactured under controlled production conditions. This ensures that the entire unit will maintain its performance for years of intensive use.
Smooth installation process
The lightweight construction of the prefabricated element means that no crane is required for installation, but using one does reduce the time needed for the work. You gain a solution that is fully compatible with FAKRO accessories – both internal and external – allowing you to tailor the dormer to your aesthetic and functional needs. The entire system becomes an integral part of the attic, while maintaining high thermal insulation parameters and structural integrity.
