Exploring your options
Fakro and Velux are two of the best and most reliable brands when it comes to roof windows. The roof windows are top quality with stylish finishes and manufactured from strong, energy-efficient glass.
What is a Fakro roof window?
Founded in 1991, Fakro is the fastest growing roof window manufacturer globally and dominates 15% of the market. Its UK office and warehouse is based near Derbyshire but the brand operates in over 60 countries. Fakro Roof Windows are available at reliable stockists like Eurocell.
What stands Fakro roof windows apart is the excellent quality and peace of mind you get by purchasing from a trusted brand.
The windows have a low U-value of 1.1, which means it’s hard for internal heat (from your central heating or heating appliances) to escape, while any cold air from outside is prevented from entering. The windows are also well insulated with thick frames and double-glazing. Fakro’s flat rooflights, for instance, are filled with argon gas to improve insulation, ensuring your rooms stay warm in the winter and cool in the summer.
This means it’s an energy-efficient and sustainable option for homeowners to cut down energy usage and heating/cooling bills.
Fakro windows are manufactured using Energy Star approved glass, which is actually proven to lower energy bills by up to 13% on average. The glass also has a special coating to protect against UV light.
Fakro flat rooflights are manufactured from double glazed, P2A glass – a version of laminated safety glass – which means it’s impact resistant and if it does shatter, it’s held together to reduce the risk of injury. It’s also compliant with European burglary resistance class RC 2 N.
The windows are the less expensive option out of the two but still high performing. With Fakro, you can make the most out of the glazed area because it’s around 16% bigger compared to its competitors.
Eurocell’s Non-opening Fakro flat rooflights are priced at just over £670, while the manually-operated opening ones are just over £850.
What is a Velux roof window?
Velux has been operating for decades longer than Fakro, since it launched in 1941. It was originally founded in Denmark and came to the UK in 1954. Today it operates in 35 countries serving a range of stylish and modern roof windows.
Velux has strong sustainability standards and was awarded a gold EcoVadis rating in 2023 for its carbon management system. The roof windows are built using sustainability sourced wood with partners accredited by the Forest Management Standards (FSC).
The roof windows are suitable for rooms including attics, kitchens and lounges, helping to bring in 18% more daylight on average and two times more daylight compared to facade windows. This helps to provide natural heating [link when live] in your home and cut down your use of electric heaters, fans and central heating. The windows are also very durable and designed to last for up to 30 years.
The window roof frames are completely airtight to prevent any cold air from coming in or heat from escaping. And they’re manufactured from ThermoTechnology glazing, which improves insulation and energy efficiency. Velux’ standard roof windows have a U-value as low as 1.2.
