Floor Insulation
It has been well documented that heat loss through a ground
floor consists of two components:
heat loss through the floor perimeter, which is proportional
to the length of perimeter and the temperature difference
between inside and outside heat loss through the ground which depends on the
temperature difference between inside and outside and the
overall floor area.
The greatest heat loss through an uninsulated floor is from the
edges. Insulating the floor perimeter in a 1 metre
band, will not only provide good insulating results
but will also prevent the risk of cold bridging at the junction of
the floor and external wall.
The thermal performance of an uninsulated domestic floor
slab, however is relatively poor. To enhance the thermal
performance, complete rather than perimeter insulation may
need to be adopted.
Complete Floor Insulation offers significant advantages over
perimeter insulation when considering the floor dimensions of
typical dwellings, e.g. it provides quick response to heating.
Description of K3 Floor Insulation
The Kingspan Kooltherm K3 Insulating Floorboard is faced on both sides with a plain (coated) glass tissue autohesively bonded to the insulation core during manufacture. The core of Kingspan Kooltherm K3 Floorboard is a premium performance CFC/HCFCfree rigid phenolic insulant of typical density 35 kg/m3. Kingspan Kooltherm K3 Floorboard is manufactured without the use of CFCs/HCFCs and has zero Ozone Depletion Potential (ODP).
Application of Floor Insulation
The main applications of the Kingspan K3 Cooltherm Floor Insulation system are;
