5 Reasons to Make Your Building as Airtight as Possible

Before you can complete your build, every new property must be tested for air tightness. A measure of the air permeability of your building, the smallest gaps in fittings, seals and infrastructure can make the difference between passing and failing this assessment. However, it’s only in the past decade that people have started to care about air tightness. Why? Let’s take a look at the reasons why air leakage is so problematic.

  1. Improved Comfort

Draughts can enter a property through even the smallest of gaps in the walls, doors and seals that surround vents and service pipes. By sealing all joints and fittings securely, you can ensure that the only air entering and leaving the property is controlled, such as air flow via ventilation pipes. In doing so, you can achieve a home or commercial property that offers comfort to those within, year round.

  1. Reduced CO2 Emissions

Air leakage can significantly reduce the energy efficiency of a property, making your heating systems work harder to heat the building. As a result, air tightness can have a big impact on the CO2 emissions of a household or business, which is one of the reasons why it’s received so much attention over the past decade. With environmental concerns becoming ever more important, every little helps in reducing carbon emissions.

  1. Lower Heating Bills

Energy efficiency relates directly to energy consumption; if the energy rating of your property is low, it will cost more to heat. That’s why air tightness is in the best interests of any homeowner or business. By preventing air leakage, you can heat your home, office or retail space for less, to reduce running costs without compromising on comfort.

  1. Fight Against Allergens

However, it’s just not hot and cold air that can cause problems where air permeability is concerned. Gaps in your walls and flooring can also let unwanted – potentially even harmful – irritants into the property. These can range from dust and pollen to unpleasant odours and insulation fibres.

  1. Legal Compliance

Compelling as the reasons above may be, one of the most pressing reasons to ensure air tightness during your build is to comply with legal regulations. Since 2006, buildings must meet air permeability standards in line with Part 1 and Part 2 of the Building Regulations. If your newbuild fails to pass the air tightness test, you could face a lengthy process to address air leakage before you can complete construction.

Although every new building must meet air tightness standards by law, this isn’t the only reason why you should take steps to prevent air leakage. Create an airtight environment with controlled ventilation, and you can reduce running costs, improve comfort, and ensure that only fresh air flows throughout your property.
