Air Leakage Rating, Internal Structures:

R P Compliance Testing Ltd provides pressure testing for air leakage rating on a range of internal structures including pressure testing raised floor systems. 

Where access/plenum floor voids are designed to be conditioned spaces or with acoustic properties, they should have a high level of airtightness to ensure leakage does not occur into cavities, risers, stairwells and other adjacent zones or into occupied spaces. Floor systems are designed to ensure that air supply is only discharged through diffuses or grilles and not between tiles. This is necessary so that the air is only supplied to where it is needed and maintains energy efficiency. A poorly sealed floor system could create serious inefficiencies in terms of costs and energy use, or sound insulation performance. BSRIA guidance ‘Floor Void Airtightness’ recommends upper limits of airtightness be included within design specifications, and that floor systems are measured on site to demonstrate compliance.
We provide testing on:
  • Ventilation/air conditioning ducting
  • Platform floors (access/plenum)
  • Plenum ceilings designed to extract smoke
  • Smoke/Fire shafts, escape routes
  • Room integrity for Clean Room, Fire Resistant, etc
Included in the service is:
  • Testing at any time of day 24/7 to minimise disruption on site
  • Trained and qualified engineers
  • A wide range of testing equipment to handle all floor & void types/sizes
  • Personal service working with our Clients to attain the desired results
  • Leak identification using high powered, oil based smoke machines
  • K41 specification testing for air tightness of raised access flooring and under floor void leakage
  • Prompt turnaround of tests certificates/reports
