What role does a thermal break play in an aluminium window frame?

A thermal break is a structural insulating section placed between the inner and outer aluminium profiles. By interrupting the metal’s natural conductivity, it slows heat transfer, helps prevent interior condensation, and significantly boosts the overall energy efficiency of the window.

Q: Are aluminium windows more expensive than PVC options?

Aluminium typically has a higher initial purchase cost than PVC due to material and fabrication. However, its longer lifespan, minimal maintenance, and slimmer sightlines often provide better long-term value. Factoring in durability, the cost difference narrows over decades of use.

Veelgestelde vragen

How do aluminium windows compare to wooden windows in terms of thermal insulation?

Modern aluminium windows with thermal breaks perform comparably to wood. The thermal break, a reinforced polyamide barrier between the inner and outer frame, minimizes heat transfer, preventing cold spots and condensation. Together with double or triple glazing, they achieve excellent U-values for energy savings.

Can aluminium windows be custom-made to fit unique architectural designs?

Yes, aluminium is exceptionally versatile. It can be extruded into slim profiles that support large glass areas or bent to create arches and angles. Manufacturers routinely produce bespoke shapes, colour finishes, and hardware configurations to match historic renovations or contemporary new builds.
