First-ever A++ tag for a VS
12th April 2016

Trade fabricator DUNGANNON WINDOW COMPANY LTD has been awarded the UK’s first-ever BFRC A++ Rating for a PVC-U Vertical Slider and also achieved the lowest ever U-Value for the style, at 1.0 W/m²K.

The achievement, for its Eurosash Superior Triple 1.0 window, also means the low U-Value even brings it within reach of Passivhaus standard in some buildings.

Developed in association with Spectus, the window uses 28mm Krypton-filled triple glazing with twin Thermobar spacers and mixed thermal and steel reinforcing, along with Eurosash’s own 12-part sealing system for reduced air leakage.

Dungannon Director Gary Givans said the company could still have gained the A++ label with a window U-Value of 1.1 W/m²K but, he said: “We believe both U-Value and Passivhaus are becoming more significant so we decided to go the extra mile. It took a lot of hard work to get there, and with a lot of support from Spectus, but the early feedback from the trade tells us the Eurosash Superior Triple 1.0 will open up whole new markets in both domestic and commercial.”

He explained that a building may be able to achieve Passivhaus status with a window U Value of 1.0 W/m²K, given that the glazing has a centre pane U Value of 0.7 W/m²K as well as the exceptional airtightness, along with other additional measures to meet the standard.

W hile the BFRC Rating scale applies specifically to the UK, it is also widely recognised in the Republic of Ireland, where Dungannon also has many customers, he added.
