Drafts and cold spots caused by recessed
When the heating in
your home is switched on the air heats up and expands. Heated air rises
and with the increase in pressure it will push towards the highest point
of your house. The heated air will force its way out through any
penetration in the fabric of your house including penetrations for
recessed lights. You now have a leakage of warm air and this leakage
will create suction. Cold air will be drawn in through fireplaces,
service penetrations, under doors and windows and anywhere that is
not completely air-tight. cold air will also drop from the roof space
causing a downward cold air channel. The
only effective way to treat this issue is to reduce warm air leakage as much
as possible as when less warm air leaks out, less cold air is drawn
and forced in.
Install Downlight Covers over all recessed light penetrations to cold
Insulation levels in the roof
space should be kept constant and un-broken but insulation
coverage alone will not prevent cold down-drafts. Downlight Covers,
when fitted as instructed, will create an air-tight seal around
recessed light penetrations and totally eliminate the cold draft
effect around the recessed light penetration. The sealed
Downlight Cover can then be insulated over allowing
for full and uncompromised levels of roof insulation.
Warning: Never use clay flower pots to cover
recessed light fittings. they do not allow the heat to dissipate away
from the fitting and can cause overheating.
