Airtightness

Airtightness is the control of airflow in a building
When a building is properly fitted for Airtightness leaks DO NOT occur at ceiling or wall junctions or plaster board joints
These leaks create discomfort & heat loss which means that the heating has to operate at a greater capacity to compensate
A building that solves for Airtightness also protects the structure over its' life time because there is no moisture condensation which causes rot, damp, condensation or mould growth which has an extremly high allergic potential which is harmful to health

Airtightness is absolutely essential in maximising the effectiveness of thermal insulation, ensuring vast savings over a lifetime.
It is environmentally friendly & reduces CO² emissions
Owners & tenants want to save on heating costs with a cost-effective thermal insulation system
Fossil fuel can be damaging to the atmosphere & reserves are limited
Only a reduction in CO² emissions can mitigate the green-house effect & protect the environment
An airtight building envelope represents the state of the art. All indications lead to the inclusion of airtightness requirements in future revisions to the Building Regulations
In order to maximise effectiveness, every new or refurbished thermal insulation system requires a functioning airtight seal.

The insulation is sealed on the outside by the breather membrane & on the inside by the airtight seal e.g. vapour check
The insulation is doubly protected against outside air by the breather membrane & against penetration of indoor air by the airtight seal e.g. vapour check
