Domestic Airtightness Testing
Aldas can help home owners with air testing leakage investigations and thermographic inspections, to advise how to reduce your heating and energy bills.
Aldas undertake bespoke and complex testing. leakage investigation and thermographic inspections for challenging homes and major projects requiring exceptional airtightness targets.
Non-Domestic Airtightness Testing
Minimising air-leakage risks is a key part of delivering large low energy non-domestic buildings. Aldas assist with early design reviews and the development of robust air barrier strategies.
Aldas have been involved with some of the largest and most complex testing in the UK to date, including the St Sidwell’s Passivhaus swimming pool. We carry out various air tightness tests with full reporting.
Aldas undertake direct inspections, air velocity measurements, non-toxic smoke application and infra-red thermography to diagnose and find air leaks to help you achieve minimal air leakage.
Aldas can assist you no matter what size your project or what kind of building it is. All Passivhaus and low energy non-domestic buildings are catered for, schools, health care facilities, student housing etc.
Designing for Airtightness
Prevention of airtightness problems starts with the earliest design phases. Aldas reviews the airtightness design, working with your team to minimise air leakage risks and ensure that’s sealing strategies are robust and resilient.
Air Barrier Strategy
A robust air barrier strategy underpins the design of your airtight project. It informs the essential specifications for airtightness and is a valuable training tool for the whole site team delivering your low-energy building.
Proving success in low energy projects requires evidence. Hence record keeping, quality control and planning the airtightness testing is essential. Aldas’s experience will assist your team in overcoming these challenges.
Airtightness design must be practical. Considering the order of works, identifying hold points and interim leakage testing needs during the design phase is essential. A buildability workshop ensures successful delivery.
