The New Zealand Building Code E2/AS1 acceptable solution requires window and door frames to be positioned on the exterior of the cladding.
While a proven solution for weathertightness, this construction method, when combined with conductive joinery materials such as aluminium, can lead to thermal bridging to the inside of the building envelope resulting in a significant decrease in thermal performance of the overall wall system.
The system is comprised of a set of aluminium flashings that link together with moulded connection parts to form a deep window recess. The Eurotect system enables aluminium, timber and uPVC windows to be recessed into the framing line from the outer façade, providing a natural deep window recess.
This clever solution achieves a clean and contemporary look for buildings and improves thermal and weather-tightness performance – particularly relevant in colder environments.
