David Ellerby, a National House-Building Council (NHBC) registered housebuilder based in Cheshire, turned to Dakea when seeking a roof window for his four-bedroom detached properties in rural Wilmslow. Heat insulation and energy efficiency were influencing factors in his specification, as the high quality properties are surrounded by open, picturesque farmland.
David Ellerby said, “to gain a better understanding of the options available, I visited my local Jewson branch in Stockport. Its team introduced the Dakea brand and the company’s heritage as part of the roof window manufacturing, VKR Group.” David specified the Dakea Ultima for his properties after Jewson arranged a meeting with Dakea sales representative Christopher Phillips.
David continued, “the Ultima offers features
and quality that are easily comparable to
triple glazing – at a fraction of the weight
and a cost-competitive price. With a
U-value of 1.2 W/m2K resulting in superior
heat insulation, the Ultima will improve the
properties’ energy efficiency and ensure a
the comfortable indoor temperature all year
Containing Comfort Glass technology, the pane shields against ultraviolet (UV) light, reflecting 95% of harmful UV rays. This unique glazing construction also ensures properties are kept cool during the summer and warm during winter, to reduce household energy bills. Simple and easy to maintain, the Ultima also incorporates Titan Glass. This exterior titan dioxide coating breaks down organic materials, allowing it to be washed away by rainfall – significantly reducing the need for manual cleaning.
The Ultima is also supplied with a transferable market-leading 20-year warranty. David added, “the warranty provided with the Ultima gives real peace of mind to both housebuilders and customers - with its lifetime warranty against hail damage offering confidence and protection long after the property has been purchased.” With the first phase of the development complete, Mark Backhouse, a roofing contractor with more than 35 years’ experience, has currently installed 10 of the 20 Ultima windows specified for the project. Mark Backhouse said, “this is the first time I’ve installed Dakea Ultima roof windows – and it was a easy and quick process. By using the Ultima’s free Insulating Foam Collar and Underfelt Foil Collar (RUC) accessories, every installation is completed to a high quality and offers a great finish.”
These tools ensure the roof is protected with a secure and weather-tight installation, and significantly reduces the potential for cold draughts and water ingress. Christopher Phillips, Area Sales Manager at Dakea said, “The Ultima roof window is ideal for housebuilders looking to future proof their properties and add value for their customers”. “With a U-value lower than both European and UK requirements and a 20-year warranty, the Ultima is the smarter choice of roof window for both housebuilders and installers alike.“ Dakea incorporates more than 75 years’ experience in roof window design, manufacturing and innovation into all its products, including Ultima, as it is part of the world’s largest roof windows manufacturing company, VKR Group.
