Koos and his team from
PFC-Sprayfoam
were back on site the last couple of days, applying their expanding
closed cell spray foam insulation to the exterior of the brickwork.
The insulation was sprayed inbetween the timber battens, directly
onto the brickwork, to a minimum thickness of 25mm. This means that
the walls can now act as an internal thermal mass, isolated from the
external extremes of temperature. The house is now effectively
watertight, draught proof, and very well insulated. We believe this
to be the only house in Cape Town [perhaps in all of South Africa]
which is insulated in this way and to this standard. The same
sprayfoam insulates the roof, we have 50mm polystyrene insulation
below the ground floor slab, and all windows are double glazed. We
expect this home to be super comfortable in both hot and cold
weather, no more need for air conditioning or heating!
