Window + Doors account for more heat transfer in an insulated building than any other building component. Up to 60% reduction in heat loss can be designed into thermal windows. Designed in New Zealand and inspired by European technology, this thermal break technology is unique to Alumax. Thermal break technology is applied to the outside of your joinery so the cold has no chance of making its way near the warmth inside. Thermal break technology works better as a ‘barrier’ which results in advanced thermal performance.
