Air Tightness

The phrase 'Airtightness' often conjures up the image of an uncomfortable, stuffy, sealed space with no circulation of air! The reality is that airtightness refers to the minimisation of draughts into the house and warm air leakages out of a house. Effective ventilation is an essential part of a healthy living space; however air leakage or a constant draught is most certainly not. The key is to 'build tight and ventilate right'.

Save Energy

Save Energy: Even when houses are well insulated, up to 60% of energy is lost due to leaks in the building's external envelope. Cold air penetrates through these joints and seams in the form of drafts. This unwanted air movement is heated by your heating system as it struggles to maintain a constant level of warmth. As a result the average house built in Ireland ends up having to heat 4 to 5 times more air then is actually needed in order to maintain a comfortable temperature. 
A well-installed airtight layer reduces these unwanted drafts and air leakages, reducing the amount of air you need to heat in order to maintain your comfortable temperature. This saves energy and results in an environment in which you can control the temperature, ventilation rate and air humidity.
