How WarmCore improves your home
Saves you moneyDue to a unique thermal core, WarmCore retains heat better than aluminium and wooden alternatives which can reduce your energy bills
Retains heatCompared to standard double glazing expect a better hear retention of 25-75% - a real bonus in those cold Winter months!
Improves SecurityLaminated glass is available as an upgrade, making the glass in your WarmCore doors and windows virtually unbreakable.
25% more thermally efficient
than the competition
outperforms the rest
WarmCore is more efficient at keeping heat in your home than traditional aluminium doors. Yet, it doesn’t compromise strength as the outer faces of the profile are high grade aluminium, positioned to add the greatest structural rigidity.
Increase the efficiency of your WarmCore
What is a u-value? U-values measure how effective a material is as an insulator. The lower the U-value is, the better the material is as a heat insulator. Current Part L Building Regulations require a U-Value of 1.8 W/m2k for replacement doors.
Double Glazed units
High thermal performance as standard
We offer a range of glass upgrades to further enhance your Warmcore product, but even our standard double
glazed units are thermally efficient. Our glass units are optimised for heat retention by using a warm edge spacer
bar and argon gas inside the unit.
U Value of 1.5 on standard glazing
We offer a range of glass upgrades to further enhance your Warmcore product, but even our standard double glazed units are thermally efficient. Our glass units are optimised for heat retention by using a warm edge spacer bar and argon gas inside the unit.
Thermally efficient glazing
To improve the thermal efficiency of our products, all glass units have a warm edge spacer bar and argon gas injected into the cavity of the unit to assist with heat retention.
Triple Glazing Upgrade
Increase your thermal performance
Upgrade your standard 28mm double glazed units to our 44mm triple glazed option and crush your energy
bills! Triple glazing performs 75% better than standard double glazing, and reduces the whole door U-value
from 1.4 to 1.0.
a thicker glass unit with an integral pane of glass is a great way to increase the energy performance of your door or window - upgrade to triple glazing and improve the U Value to an impressive 1.0.
A glazing option to
suit your needs
Triple glazing is a perfect upgrade for; larger houses that take longer to heat, older properties prone to cold draughts, homes next to busy/noisy roads, customers looking to reduce their energy bills.
