WarmCore aluminium and PVC windows compliant beyond Part L

3rd September, 2021

Solar Windows’ WarmCore range of hybrid aluminium and PVC windows is 25% more thermally efficient than traditional aluminium systems, its critical ingredient being the unique full width thermal core which helps prevent precious energy being conducted outside the home.

And with an uplift in Part L Building Regulations coming this December and legislation becoming a reality in June 2022, WarmCore is one of very few aluminium window products on the market, which not only complies with, but goes above and beyond, the new requirements.

WarmCore is a well-established product in the marketplace and, under the stewardship of the Solar Group, will play a major role in delivering an effective solution in line with the pending changes to Part L of the Building Regulations.

Solar will be exhibiting WarmCore tilt and turn and casement windows at Housing 2021, all of which feature strong, high grade aluminium outer faces, internal beading and multi-point locking, plus the casement versions offer a flush sash option. All include a ten-year product guarantee. The tilt and turn models tilt inwards for easy natural ventilation and a greater flow of fresh air as well as swinging inwards for easy cleaning.

With a U-value of 1.3, WarmCore is 25% more thermally efficient than traditional aluminium systems, rising to 75%, when triple glazing is chosen. Hence, using 44mm triple glazing rather than 28mm ‘standard’ double glazing reduces the U-value rating from 1.3 to 0.8, making this option ideal for exposed locations. Weather tightness is improved even further with Q-Lon polyurethane foam seals, to keep draughts out, with rubber gasketed beads providing a second weather seal, exceeding the BS6375-1 classification.

Carl Lewis, managing director of Solar Windows Ltd, said: “With the built environment contributing around 40% of the UK’s total carbon footprint, the emphasis rightly must be on urgently reducing CO2 emissions, so products like WarmCore will only grow in importance in the coming months and years.
“Specifying sophisticated products like this is one way in which Local Authorities and housing associations, as well as the wider house building sector, can help ensure their building projects contribute towards Net Zero.”
