Structural Insulated Panel System – panels, made of rigid insulation between structural facings. Our panels are factory-made in New Zealand and provide a high level of structural strength, rigidity and insulation. They can be used for floors, walls and roofs, replacing the timber framing, batts and rigid air barriers. Panels are load-bearing, capable of spanning distances on their own, and providing bracing all in one.

A stronger building. Stronger in a cyclone, stronger in an earthquake, and better impact resistance. You won’t need to find a stud in a wall – you can attach anywhere. Better insulation. Anywhere from 2x to 6x as much. Read the section about ‘R-Value myths’ Less air leakage. About 20x less. More fresh air. We’ll make sure you get a suitable MHRV so that you get fresh supplied air, dispose of stale or damp air, and don’t lose the heat you have. With MHVR, there will be no condensation. Full stop

Because we make a premium quality product which is sold with less markup. Our quotes break down the panel cost as well as the accessories needed to finish the structure. We work with community groups to get them bulk product at discounted rates.

Standard houses will ‘sweat’ on the inside, especially if you sleep with the windows closed. Most of us release about 2 litres each per night, and it has to go somewhere. Some goes out under the door, some through little gaps around the windows, some through the plasterboard, and some just condenses on the walls/curtains. Most people know HRV/DVS. They are basic fans that pulls air from your attic, down into your house. This brings the most heat on a summers day, and no heat when there’s no sun. Aside from poor thermal performance, your SIPS build probably won’t have an attic, and your building will be too airtight for a positive-pressure system. A MHVR has two fans, one to suck waste air from your house, and another to blow fresh air in. The two airflows pass through filters, and a high-efficiency heat exchanger. The ones we recommend achieve ~94% heat recovery. If it’s warm inside in winter and cold outside, you get fresh air, but at indoor temperatures. Most units have variable speed fans (from zero up to a light breeze) and can be controlled by moisture level, timers, CO2 sensors or manually.
