Air Permeability - less than 0.36m3/h/m2 (Appendix to test result)

We are pleased to add an appendix by HRS Services to clarify the airtightness of our product, to assist you in specifying Elite Airtight on future projects. (Ideal for BREEAM, Passivhaus etc.)

APPENDIX TO 109848AT REPORT ON BLOCKWORK AIR PERMEABILITY FOR

PRISTINE ELITE AIRTIGHT COATING 21.03.11

 

Where we have stated the permeability is too low to detect we can qualify this comment with the

following statement:

 

Where the air permeability is less than 0.36m3/h/m2, no exact value can be obtained due to the

resolution of the instrument. This represents very low levels of air leakage and an Air Permeability no greater than 0.36m3/h/m2.

Environment and Sustainability Centre in Cornwall - built to BREEAM Outstanding standard

The University of Exeter's Environment and Sustainability Institute (ESI) is a £30 million interdisciplinary centre leading cutting-edge research into solutions to problems of environmental change.

Elite Airtight was chosen as the best option for achieving airtightness on the block walls throughout the building. Approximately half of the walls were going to be hidden by dry lining and other coverings, whilst the other half were in open public areas where the finished walls would be left on display. 

Read all about the project in Construction News 12 July 2012 

Upon completion and under the supervision of Trident Airtech the air leakage test results came in at an excellent 2.72 m3/hr/m2

 

St.George’s Primary School in Kidderminster - designed by Howl Associates, constructed by Thomas Vale.

Elite Airtight was chosen for application onto various walls throughout the school. Elite Airtight is touch dry within a few hours and is ready for dry lining or other surface work the next day, this is an important factor on construction sites where bad weather causes delays to the construction programme. The school achieved air leakage rates of less than 2.5m3/sq.m/hr.

 

Elite Airtight was specified by Mosaic Architecture for use on the Hamilton International Offices.
 
Craig Crombie of Mosaic Architecture comments: "We chose Elite Airtight to help achieve the required airtightness in the Hamilton International Offices, we decided that the interior surface of the block walls would be the preferred surface to achieve an air barrier and whilst we could have chosen a parge coat to achieve the airtightness, we realised that Elite Airtight had advantages over parging which included, less mess, less material, better finish, quicker application and similar cost. 
We have been happy with the product and the contractors applying the Elite Airtight - PFP Ltd - have also expressed their satisfaction with the application of the coating and the final finish."
 
Elite Airtight offers an extremely acceptable finish on block walls with a surface that is smooth to the touch and can be wiped clean. In this instance these features of the product were incidental as the primary objective was to achieve a good quality airtight barrier quickly, cost effectively and with the minimum disruption. 
 
Another additional benefit to placing the air barrier on the inside walls is that it reduces the amount of warm air (in the winter) or cool air (in thesummer) dissipating into and through the walls, thereby allowing the HVAC to reach optimum temperatures quickly and efficiently.
