Hytherm,
in conjunction with the Building Research Establishment (BRE)
have conducted a number of computer model tests by the TRISCO
method to determine ‘Best Practice’ procedures for areas in
construction that are normally prone to problems resultant
from Thermal Bridging.
Thermal
bridging occurs when there is a break in the continuity of
the insulation layer, this results in heat loss. The inside
surface of the thermal bridge is colder, and the outside surface
warmer than the surrounding insulated surface area, attracting
any moisture within the construction which will condense at
that point. This thermal bridge, if exposed to persistent
moisture within the building, will result in mould growth,
which is one of the major sources of respiratory allergies
such as asthma. It can also cause deterioration of the building
fabric at that point, and effect materials within the construction
such as roof timbers.
