Why Choose Dakea?

"Dakea is the roof window choice for smart proffesionals" - Dakea

At Dakea, we pride ourselves on delivering high-quality, affordable roof windows that create stunning, quiet, energy-efficient and safe rooms in any home. Our roof windows are manufactured to the highest standards and backed by a 20-year guarantee which gives our partners peace of mind. But the real difference with Dakea is the long-lasting working partnerships we build with professional homebuilders, roof window installers and merchants.

Team building

We support our partners every step of the way; from choosing the right roof window through to installation support and aftercare. Dakea is part of the VELUX reward programme which allows you to earn rewards for every Dakea roof window you purchase.

Our heritage

Dakea is owned by Altaterra, a business that's been established in the UK since 2001 and, as part of the VKR Group, is built on more than 75 years of industry experience.Dakea was launched in 2012 to provide high-quality affordable roof windows for the professional market.

Always quality

Dakea windows are manufactured using top-quality raw materials to the highest production standards and independently tested to ensure they meet with our exacting standards. Our eco-credentials are also important to us and we only use wood sourced from sustainable forests that have been certified by the Forest Stewardship Council.

Production

With more than 75 years of experience in roof window manufacturing, we have reached the highest manufacturing standards possible. Learn more about our production processes and why we are so confident about the quality of the final outcome – the dakea roof window with its 20-year guarantee.

Quality pane

Toughened and laminated float glass, covered with special tear-resistant, sound-insulating foil, with a low-emissivity or easy to clean coating. The selection of Dakea glass panes has been specifically designed for safety, energy-efficiency and indoor comfort.

Easy clean pvc

Thanks to our milling tools, which have a speed rotation of up to 18000 per minute, the profiling of our windows are smooth and precise. The insulated and steel-reinforced PVC material is carefully welded together for maximum strength of the final product – the Dakea PVC roof window.

Masterwood

Carefully selected and sourced from renewable forests - FSC certified Nordic Pine is the main element of all wooden roof windows in the Dakea range. Our rigorous production process is designed to make the pine even better quality with: humidity-controlled storage, lamination, eco-friendly water-based varnish, drying and more.

Tested with a 50 kg impactor

We hit our Ultima roof window with a 50 kg impactor. It might sound extreme, but then so might be the weather. The result? Nothing happened. Proof that our windows resist even the most extreme weather conditions.

Tested with 600 litres of rainwater

Imagine 600 liters of rain falling in just one hour. That’s the equivalent of the amount of annual rainfall per square meter in London! And that’s the amount we dropped on our Ultima roof window to check its water tightness.

Tested against144 km/h speed winds

We checked the resistance of our Ultima roof window to hurricane winds. Even such extreme conditions didn’t damage it in any way. Windproof approved

Tested with 100db noise

We tortured our window with 100dB of noise which is equivalent to the noise made by an electric drill. The result? Our Ultima window reduced the amount of noise by 50% compared to a standard roof window.

Certifications

Highly accredited

We are so confident about the high quality of our windows, that we give them a 20 year guarantee - the longest guarantee on the market. We take quality very seriously and have a list of certificates to prove it.

Outstanding quality control

We accept only the best so our production is rigidly controlled to make sure it meets the highest possible standards. We have certificates to prove that too.
