Let in more natural light

Achieve a brighter room, without the need to add more windows, with FAKRO. Placing the handle at the bottom of our windows has allowed us to achieve up to 10% more glazing area within the same dimensions as a standard window.

Increase energy-efficiency

Save on heating costs and reduce your carbon footprint, by installing a FAKRO roof window. Our range includes the FTT U8 Thermo, the most energy-efficient roof window in the world, and our special packages of insulation flashings and ‘warm’ Thermo flashings mean you’re guaranteed to make energy savings all year round.

Create a sustainable energy balance

Continue to let the fresh air in, even when your windows are closed, with our energy saving V40P automatic air inlet. With space to place the air inlet in the upper part of the frame rather than in the sash, FAKRO windows allow for automatic control of fresh air inflow, limiting heat loss in the winter and saving you money on energy.

Install easily with our versatile installation system

Ensure your roof window’s long-term performance with proper installation. Using mounting brackets, our windows can be fitted to either battens or rafters and can be installed at three distinct depths.

Keep safe and secure

Keep your home protected with topSafe, FAKRO’s unique system of window reinforcement. Used in conjunction with toughened external glass, the system significantly improves resistance to break-in attempts and protects against the sash opening if inadvertently stepped on.

Get more out of our windows

Choose from unique products and innovative solutions, developed in our modern Research and Development Centre. We put more investment into our windows, so that you can get more out of them. Innovation is at the heart of every new product we create, which is why FAKRO holds more than 100 patents and patent applications.

Bring your design ideas to life

The roof windows you choose will become an intrinsic element of your home’s interior design. The highest standard of manufacturing coupled with attention to styling mean that all FAKRO roof windows offer the critical combination of quality, functionality and stunning visual appeal. From the exterior, profiles are modern and compatible with any roof structure or pitch.

Choose endurance

When you buy a FAKRO roof window, you can be sure it’s built to last. FAKRO roof windows have been designed to function effectively in the harshest environments, so that they meet the highest standards of durability.

Be Green

FAKRO products are designed to provide the highest standards of thermal efficiency while being manufactured using replenishable natural resources. Low profile solar panels can also be used in modular form with FAKRO roof windows to enable free energy to be harvested.
