We have a full range of ventilation units dependent upon specific requirements.

We've been doing this a long time and it can be a little confusing trying to decipher all the requirements. If you're unsure about what you need, then please give us a call for some friendly and free advice. Call us on (028) 9268 2768.

New build properties:

For a new build property if you wish to omit trikle vents in the windows, and extractor fans elsewhere, then you'll need our British Board of Agrément (BBA) approved loft mounted unit. Of course it's a little more costly, but then approvals are expensive. One unit will meet all of the Northern Ireland ventilation requirements listed in Technical Booklet K.

The cost savings in omitting trikle vents and extractor fans will more than cover the cost of the unit. Remember also that you only have one easy installation in the loft and don't have to bore through walls as you would with extractor fans! Time is money after all.



The loft mounted unit is a sophisticated whole home ventilation and condensation control unit for homes with a loft space. The unit gently ventilates the home from a central position on the landing in a house or the central hallway in a bungalow to transform a stagnant, stale atmosphere into a fresh, healthy, condensation free environment.
