Nga Whakapiri Raima Maamaa | Nga Kaipupuhi Hukarere Mahinga Nui mo te Raima Pukoro
te tuanui raima pahuka is a type of insulated roof with the same characteristics as normal concrete but containing bubbles of air inside. He maha nga painga penei i te ngawari, easy installation and good insulating properties.
Kiato – Dry density of foamed concrete ranges from 400 ki 1800 kg/m3 but it depends on how much foam is used in the mix design.
Te Kaha Kōpeke – Foamed concrete has higher compression strength as compared to normal concrete and it can be used for structural purposes.
Weahanga wera – The insulation properties of foamed concrete are improved over normal concrete as it has lower thermal conductivity.
Maamaa – The weight of the finished foam concrete slab is low and it can be produced at a lower cost than conventional insulated concretes.
Slope negotiation – The slope of the foam concrete can be controlled easily by changing the water content and mixing ratio.
Sound Insulation – The soundproofing and anti-noise effects of foam concrete are enhanced by the use of different types of foam.
Bearing Capacity – The compression capacity of foam concrete can be increased by adding a pre-formed or pre-cast component.
Energy Efficiency – Cool roof roofing technology system combines a solar powered fan, moving air cavity (MAC) and lightweight te tuanui raima pahukaing to reduce the attic temperature in industrial buildings.
Wind Resistance – Foam concrete can be installed in the form of a single layer over existing roofs or as a two-layer composite system with EPS insulation boards for high wind resistance.
