Thermally broken aluminium windows and doors
What is a thermal break?
Double glazed windows or door glass have long been trusted solutions for helping to regulate temperatures, keeping interiors cool during summer and warm during winter. The science behind double glazed windows is that by trapping a layer of argon gas between two glass panes, separated by non-conductive spacers, double glazed windows effectively block heat transfer through conduction. This innovative technique, known as a "thermal break", involves strategically positioning poor heat conductors between heat conductive materials, like glass, to minimise thermal bridging.

So why is using only double glazing not enough?
Ever touched your aluminium joinery on a cold day? It's cold! - so it's transferring cold from outside to inside and compromising the excellent job your double glazing is doing.
Double glazing is only part of the solution to temperature control - it was discovered that the same thermal break technology used with double glazing can be applied to aluminium window frames.

A thermal barrier is created by inserting a non-conductive polyamide strip between the inside and outside aluminium profiles. This strip, typically 10-20mm wide, breaks the thermal bridge, preventing the conductive aluminium from transferring heat.
Thermally broken aluminium joinery is designed to reduce heat transfer between the inside and outside of a building, making it a more energy-efficient option compared to non-thermally broken aluminium joinery, which can conduct heat and cold, leading to higher energy losses.
What are the benefits of thermally broken windows and doors?
Improved Thermal Performance: Thermally broken windows and doors significantly reduce heat transfer, keeping warmth in and cold out.
Reduced Condensation: Thermally broken aluminium window frames combat condensation by interrupting the thermal bridge, keeping the inside of the frame warmer and reducing the likelihood of condensation.
Energy Efficiency: Reducing energy consumption is essential in New Zealand buildings, and thermally broken windows and doors play a key role in achieving this goal. By minimising heat transfer, they help align with standards for energy efficiency.
Durability and Maintenance: Thermally broken windows and doors are designed to last, with reduced risk of frame corrosion and condensation-related damage.
In New Zealand's climate, thermally broken windows and doors offer a superior solution for homeowners seeking energy efficiency, comfort, and durability.
