The flow of vapours such as Water Vapour and CO2, through the fabric of a building is critical in meeting Building Regulations, but it has been difficult to test accurately.  Often measurements on material and structures have taken days, and even weeks, and even then have been both expensive and of questionable accuracy.

Versaperm has now introduced a new version of its highly sensitive instrument to measure the permeability of building materials, barriers and even complete building structures.  Not only can it measure this for water vapour but it can measure it against most other common gases.
The flow of moisture effects both thermal insulation and “health” of the structure.  Not only that but it additionally affects the thermal insulation.  Getting it wrong can be disastrous causing mould, rot and decay.
Versaperm’s new permeability equipment is fast, sometimes taking just 30 minutes to give accurate and repeatable results. The equipment is highly sensitive, simple to use and provides automated computerised control. 
Versaperm equipment is unusual in that it can measure anything from thin films to complete wall structures, including laminates, timber, felts, adhesives, mastics and other sealing or structural materials.

Additionally, the company offers a sample testing service and technical consultancy to the building industry.
