‘Plasterboard offers almost no insulation so
the sloping ceilings lose a lot of heat,’ says
Mukti. ‘We decided that the best insulating
technique for Clovelly was to screw 75mm
PIR board onto the room side of the sloping
ceilings, followed by plasterboard, and then
re-plaster and paint.’
Around 30 per cent of heat loss in old
properties is through draughts, so draught
proofing is essential but old buildings need
ventilation to avoid damp. The traditional
Clovelly window design is unusual in having
a removable bead that the hinged casements
close against, just like a door stop. In
properties with normal window frames and
no stop bead, casements were removed and
routed in a plastic pile-carrier on all four sides
of the casement, into which an appropriately-
sized concealed brush can be inserted.
To reach E rating (39 points), some
properties also require measures such as
floor insulation above cellars, tank lagging
where not already installed, blocking up
unused fireplaces and a small amount of
external wall insulation.
‘The programme to insulate Clovelly is still
in progress,’ says Mukti, ‘and we’ve had very
positive reports from residents so far. One
tenant, who lives in a four-bedroom house,
had all four types of insulation installed over
a year ago and reported that her fuel bills had
dropped by 50 per cent, from £2,400 per
year to £1,200.’
Our awa rd winning secondary glazing
and insulation systems, created and
installed by skilled craftsmen, mean
you keep the period windows but
lose the huge heating bills.
