Lightweight steel frames, reinforced concrete, specially-formulated
rigid polyurethane foam and ferro-cement are the key components
of this innovative building method. 'Compu'
stands for 'combined PU' (rigid polyurethane
foam), the core of every Compu-Home™.
Rigid polyurethane foam (PU)
provides exceptional energy-efficiency:
- PU foam protects aircraft passengers against outside
temperatures of -60ºC (-70ºF) at 10,670m (35,000ft);
- PU insulation results in a comfortable, healthy living
environment irrespective of widely fluctuating outside
temperatures;
- Compu-Homes™ owners have testified
to body heat and existing incandescent light bulbs supplying
sufficient heat energy, even on the coldest nights.
The 'k' value, or Thermal
Conductivity of PU Foam
Rigid PU foam has exceptional thermal properties and boasts
a 'k' value of between 0.018-0.023
W/mK. The lower the 'k' value
the better the insulating ability. In comparison: Concrete
= 1.250; Brick = 1.150; Glass = 1.050; Wood = 0.144 and
Expanded Polystyrene = 0.039.
Computer-designed lightweight steel
frames form the structural framework of this alternative
building method. Tight tolerances are maintained and the
design of multi-storey buildings is possible. Skilled labour
is only required to assemble the framework and apply the
PU foam
and elastomer
roof coating. Lightweight cladding and roofing materials
result in reduced steel requirements and costs, without
compromising strength and durability.
The patented Compu-Homes™ building
method ingeniously incorporates polyurethane foam into the
wall's structure. Our completed walls are essentially the
same as the exceptionally strong hulls of ocean-going ferro-cement
yachts. They have been classified burglar-proof.
Polyurethane foam is also integrated
into the roof structure, thereby eliminating the need for
further ceiling insulation. The result is an attic free
of drafts or extreme temperature fluctuations, an ideal
additional room.
The polyurethane thickness can be
increased on-site to suit extreme climate conditions without
re-calculating or adding to the cost of the building's structural
framework.
Key Compu-Homes™ Features:
- Possible to complete a 76m² dwelling (post foundation)
in under one week;
- Insulated roof, walls and insulated floating foundation;
- Durability, low maintenance and excellent energy-efficiency;
- No moist, streaming walls or unpleasant cold drafts;
- Water and weatherproof;
- Excellent sound-absorbing properties;
- Suitable for earthquake zones;
- Homes can
be containerized and shipped globally;
- Materials
exhibit fire-retardent properties;
- Polyurethane
foam/elastomer is sprayed on-site.
Compu-Homes™ offer a viable alternative
to conventional construction methods at a time where skilled
labour and conventional building materials are costly and
in short supply.
Transport Savings
Our specially-formulated
polyurethane foam consists of two components. These are
sprayed on site where they expand almost 30 times
within seconds. Two 220kg drums of unmixed material
effectively represent 60 drums of expanded material. This
dramatically reduces transport costs and construction time
when compared to conventional building and cladding materials.
We do not transport 'air', i.e. insulating panels/blocks,
to the building site.
The Compu-Homes™ building system
is incredibly versatile: In its basic form it is ideal for
emergency housing. By incorporating the latest technical
improvements it can be adapted for multi-level villas in
affluent residential areas. Both structures display unbeatable
insulating properties.
Initial structures have a 22-year track record in South
Africa and over 60 years internationally.
The Compu-Homes™ building system
is protected by valid patent and Trade Mark rights (South
African Patent No. 2008/08546). It was also extensively
tested by Agrément South Africa and the Council for
Scientific and Industrial Research in South Africa (CSIR).
