Elite Airtight Coating for Blockwalls

Concrete block walls can leak the air in a building at up to 80 cubic metres of air every hour through each square metre of surface, at that rate it won't take long for the warm air inside to escape from the building, resulting in increased heating costs & carbon emissions.

We have developed Elite Airtight Coating to provide a fast and economical solution to the problem of air leakage through blockwork. Not only does Elite Airtight offer an airtight finish, it is also fully washable for easy maintenance, it can be left as an finished surface in any public or private areas.

The alternatives:

Plastering - expensive, time consuming, messy, requires painting
Plaster-board - expensive, time consuming, not airtight. (see Airstop Pro-Parge)
Blockfiller - more expensive, higher water content/less solids, not tested for airtightness
Paint - similar price, not airtight unless many coats are applied, unattractive finish
Bare block - no additional cost, not airtight, poor quality surface, unattractive finish, poor light reflectance

Elite Airtight has been tested for airtightness by an independent laboratory in accordance with BS EN 12114:2000 Thermal performance of buildings and has received a 100% pass when applied to standard cellular blocks, which were leaking 80m3/hour/M2 at 50pa. before application of the Elite Airtight coating and leakage "too low to detect" after application of Elite Airtight. The test was carried out on standard cellular blocks - applying Elite Airtight to blocks with smaller holes & fissures or onto paint quality blocks will result in less paint being required to complete the job. See HRS Services Appendix for results showing air permeability below 0.36m3/h/m2 in our News page.

Architects, specifiers and builders now have the option of specifying standard concrete blocks (where appropriate) for quick and economical construction projects and for the resultant walls to have a washable, airtight and decorative finish.

Elite Airtight is also ideal for use in refurbishment projects, as the coating can be applied directly onto previously painted block - making significant improvements to the airtightness of the building.
