Thermtek High R-Value Aluminium Doors

Product Description

H1 Compliant Entrance Door. The revolutionary new aluminium door utilising innovation and technology found nowhere else in the world. The New Thermtek FL door comes with an R rating of 0.56 for a door 1980 x 860mm which will exceed the new H1 building code requirements anywhere in New Zealand. This R rating will improve as the door gets larger. 

With Parkwood’s new Thermtek FL door, its outside face is able to withstand extreme temperatures and the accompanying movement caused when aluminium heats up. Due to the thermal construction, this movement is not passed onto the other side of the door. This means you can have a black aluminium door in full sun, with no resulting issues in longevity or door movement (very minimal bowing or twisting).
