Wall,
Roof and Floor Insulation
The more insulation a property has, the less power it requires for heating or cooling. Over the years the saving in energy becomes substantial.
The UK insulation standards have increase dramatically since April 2002.

Floor
insulation should be put above the slab to avoid the heat sink effect
from the edges of the floor and into the ground when using underfloor
heating systems.
IPPEC supplies all types of floor insulation and in various thicknesses.
See Pexatherm underfloor heating
section.
IPPEC stocks polystyrene in floor grade 30 50, 70 and 100 mm thick and
polyurethane in 20, 50 and 65 mm thick.
Heat loss is highest from the edges of the floor.
The highest heat loss from a building is through air changes. Warm air escapes through windows, doors, ventilation ducts, poor sealing of gaps etc. and is replaced by cool air that needs heating.
Heat is lost through window glazing is the second highest heat lost from buildings. Double glazed windows are a must and preferably with a large cavity between panes and low emissivity glass. Radiators under windows cause high heat loss.
High heat losses from windows with radiators.
The insulation in the floor must be 10 times higher than that of the floor finishs
Heat loss through the floor is higher with underfloor heating than radiator system. The more insulation there is above the pipe such as carpet the more insulation is required in the floor below the heating pipe. This is because hotter water is required in the floor heating plane. Therefore the higher is the loss through the floor. The edge insulation which is standard with IPPEC's screed systems improves floor insulation and response time markedly.
