Airtight Block Walls
Impossible? Difficult? No - Very easy!
Concrete block walls can leak air into and out of a building at up to 80 cubic metres an hour per square metre of surface. Concrete block walls treated with Elite Airtight are completely airtight.
Imagine the Savings!
Elite Airtight provides a cure for the airtightness problems associated with blockwork and allows architects to design cost effective warehouses, distribution centres, schools, sports halls and other large buildings incorporating inexpensive blockwork (where appropriate), while still meeting Part L of the Building Regulations.
This unique, specialist coating reduces airflow through the walls to a rate "too low to detect" and offers benefits which can normally only be attained by expensive and time-consuming plastering procedures.
Elite Airtight can be applied quickly and economically, making it the prefered choice of painters and decorators who have been struggling with the time and expense involved in applying numerous coats of non specialist paints in an attempt to achieve a reasonable finish.
Applying Elite Airtight over large expanses of concrete block ensures considerable savings in the heating and cooling of industrial and commercial interiors.
Specifying Elite Airtight at the planning stage allows standard economical blockwork to be used in the construction of a building but with the added benefit of an airtight, hard wearing, washable and decorative finish.
Also ideal for use in existing properties on brick and block, providing an economical yet significant improvement in the airtightness of the building.
