Slim Sightlines vs. Thermal Performance

You don’t have to compromise narrow sightlines for thermal performanceIQ are the leading specialists in narrow framed and thin profiled window and doors.

These products have an obvious aesthetic draw for architectural design due to their thin framing, allowing maximum glass sizes for even the smallest openings.   


In the past it may have been the case that in order to achieve these slim aesthetics thermal performance would have to be compromised by removing sections of thermally insulating framework.


With advances in thermal break technology and engineering, this is no longer the case.

"Even with this slender sightline Minimal Windows can achieve a standard overall Uw factor of 1.2 W/m2K"


IQ’s Minimal Windows has a narrow vertical junction of only 21mm and is thought of as the first choice of slim framed sliding doors systems for architects and designers. Even with this slender sightline Minimal Windows can achieve a standard overall Uw factor of 1.2 W/m2K, reducing to less than 1.0 when using a higher thermal performance glass panel such as Super Insulating Glass, becoming the best thermally performing minimal framed sliding door available in the UK.

Mondrian Windows are designed to replace old fashioned engineering such as Crittel and have a small steel framing of 50mm on the opening panel. But with advances in thermal break design and Ug glass factors this windows system can now achieve a Uw value of 1.6 W/m2K, in line with all building regulations and most thermal targets.


Even IQ’s newest aluminium framing sections for opening casement doors and windows can achieve slim sightlines of as little as 40mm whilst still achieving the requisite 1.6 W/m2K for thermal performance.


IQ are constantly trying to enhance the thermal performance of all its framing and glass options to up keep our ethos of slim, minimal framing whilst keeping up with the energy  necessities of today and tomorrow.
