ISOPRO - What is it for? ISOPRO is the answer to thermal bridging problems in concrete constructions. ISOPRO is the thermal break!
What does the problem look like?
What does the problem look like?
Thermal bridges are local component areas in building envelope with increased heat loss. Because of increased heat loss there is a lowering of internal surface temperature. If these fall below the minimum surface temperature θsi of 12,6°C , it promotes mould growth. Definition of thermal bridges
ISOPRO - positive effects Reduces loss of heat Saves heating energy Creates higher surface temperature inside Adds to a more comfortable residential climate Reduces building deficiencies Reduces CO2 emission
Theoretical with 100 % insulation Isopro
There is no such thing as a thermal break! The best you can hope for is the minimal disruption of the insulation All structural systems compromise the insulation to some extent
Balcony connected by continuous concrete construction – no thermal provision
Temp < 12.6 deg = risk of mould
Balcony connected to slab with 100% thermal break
Balcony connected to slab with ISOPRO – with insulation
