Thermalcrete Show Home
Our "Thermalcrete" show home at 14 Bracken Mews, The Lakes is open Friday to Sunday from 1-4 pm and demonstrates "The Future of Building"
Having spent over thirty years in the residential construction industry and experienced the warmth and durability of homes in far more extreme climates than New Zealand I question the merits of always building quick and cheap to the minimum code requirements. Cold and dampness in our older housing stock is common and state of repair often poor.
Our "Thermalcrete" show home utilises some of the best methods and technologies in the world, it has performed superbly during the summer and winter months easily maintaining a comfortable temperature and is very economical to run thanks to solar energy, mechanical ventilation and heat recovery, extremely efficient LED fittings and superior insulation.
The floor plan of 238m2 provides comfortable space for a family of toddlers, teens or adults, ample storage and a refreshing spacious feel for a similar cost to a well build conventional home.
The expressions of delight and visitor comments make this a must see and will open your eyes to how warm and quiet a home can be.
Why Insulated Concrete is Superior
Walls of 136 mm thick 30MPA concrete reinforced at 600mm centres vertically and horizontally with D12 steel bars plus steel studs at 140mm centres. Interior walls concrete without the insulation or normal 90×45 timbers. Reinforced concrete structures are often the only ones remaining after severe natural disasters, the Japanese Tsunami for example. Earthquake resistance is considerable and engineered specific to each build and location.
Having the huge thermal mass of concrete on the warm side of the wall is the secret to a cool summer home and retaining winter warmth, boosted by substantial ceiling insulation and double glazing. Careful design and orientation can mean no artificial heating may be required at all. Our standard exterior wall contains nearly three time the code required insulation value.
Other than aesthetic maintenance of plaster and paint coatings your concrete home will serve many generations. The concrete is behind four moisture resistant layers, is water proof itself and the steel galvanised or embedded. The 50 year New Zealand building code structural durability requirement is easily and confidently exceeded.
Accredited Australian tests of a standard 150mm wall panel complete with electrical conduits and plugs showed no failure at the completion of a 240 minute fire test of a structurally loaded panel. No steel, timber, concrete block or brick structure comes close to "Thermalcrete"
Virtually sound proof to airborne sound and very resistant to structural borne sound. The standard AFS 150 wall panel tested at CSIRO Australia gave a result of Rw 52 normally sufficient in use to comply with Au code inter-tenancy provisions. The whole structure has a bearing on performance
No voids or cavities to support insects, vermin or pests. Voids containing air at equilibrium moisture content EMC can cause moisture build up in materials or condensation leading to corrosion in steel framing and mould growth in many materials. The climate in many areas of New Zealand supports high EMC and instaticial moisture in our homes has proven a problem. Solid, insulated, dry "Thermalcrete" totally eliminates these problems.
No plaster board linings to damage means longer life with less maintenance. "Thermalwall" by AFS brings the durability of tilt slab commercial walls affordable to quality housing.
Computer designed and prefabricated with every wall also a beam it allows flexibility in uses and architectural design. The inherent strength widening design scope.
Speed of Construction
Prefabricated and labelled panels from shop drawings ensure fast on site erection without the cost of cranes. Framing, cladding, insulation, bracing and lining form the lightweight panel with services, reinforcing and concrete placed on site. Fewer sub trades reduces cost and errors while increasing productivity.
