NSS provide you with a wide range of airtight services and products – to ensure the right design and specification as well as construction quality – to the Irish construction industry.

Airtight, windtight, or airtightness – whichever way you say it, is basically the elimination of draughts and is a crucial component in combating wasted energy, a critical factor in any low energy build and all too often overlooked in comparison to insulation and energy sources.

Imagine wearing a thick wool jumper on a cold windy day – it might sound like a good idea until you step out into the cold and feel the wind blow right through. But if over the wool jumper you put on a jacket and zip it up, then you'll begin to warm up as the wool insulation can now do its job properly.

It's the same with buildings – even though you have insulation in your house, without a zipped up jacket, the warmth will be blown away by penetrating wind. It stands to reason that if you can keep the warm air in and the cold air out you will decrease draughts, enjoy a cosier environment and smile at smaller heating bills.

The expensive heat that you have built up in your home or office can leak out through door and window seals, up the chimney, through the attic and poorly installed or compromised vents.

Whether you call it air infiltration or air permeability, NSS can help you with the right testing, and then find for you the specified products – be they seals for walls, doors windows or whatever you might need to make that building warm and energy efficient.

Experience shows that the key to successfully making your structure air tight is to firstly get the design and specifications right, followed by the installation of the best quality products.

Two Simple Steps

1. Decide how airtight you want your building to be. Depending on your target energy consumption, you might reach for passive standards or build something that meets existing building regulations.

2. Call us to arrange how to go about designing and specifying the right products for you 01 456 5170.
