For apartment dwellers living above carparks, effective insulation is critical to maintaining thermal comfort. Without adequate separation, uninsulated structures can amplify temperature extremes for both upstairs and downstairs neighbours.
To ensure a comfortable and safe environment, the New Zealand Building Code requires apartments or commercial spaces with carparks below have a layer of thermal underfloor insulation. This takes the form of a carpark soffit liner installed in the carpark space below the apartment, to insulate the floor of the space above.
Fortunately, there’s a single, integrated solution: GreenStuf® Car Park and Acoustic Soffit Liner (ASL), a high-performance acoustic insulation installed to the carpark soffit, that ensures a snug fit across uneven surfaces typical of a concrete subfloor. It’s engineered to be thermally compliant, as well as absorbing sound energy rather than reflecting it—no more echoey phone conversations as you walk from your car to your apartment.
Carpark panel insulation is usually left exposed in the carpark, but to create a space that performs well and looks great, GreenStuf’s ASL offers the widest range of finishes on the market, available in either black, grey, or silver foil finish.
Made from recycled plastic bottles in New Zealand, ASL is both the environmental choice and the most cost-effective option; an average of 40% cheaper than equivalent rigid foam board alternatives. A Group 1-S rating for fire means ASL can be installed in any area without limitations.
It’s a high-performance acoustic and thermal insulation that you can rely on for the lifetime of your building. Plus, ASL offcuts can be recycled through the GreenStuf Takeback Programme, helping you keep your site clean and organised.
Good design aims to create spaces that work for everyone. By installing thermal and acoustic insulation, you can create a comfortable, inclusive environment for all building dwellers.
