Acoustic Insulation

We live in a noisy world. We are exposed to sounds that affect the quality of our life. There are three types of noise, airbourne noise (TV), impact noise (footsteps) and appliance noise (washing machine). The level of soundproofing which directly impacts comfort levels of an area depends directly on its insulation against direct and indirect transmissions. Acoustic insulation should be considered at the design stage as effective sound insulation fitted at the time of construction can reduce noise levels in all types of residential, industrial and commercial buildings. Sound insulation has the advantage of creating a quiet comfortable home environment and at the same time possessing thermal properties.

Fire Proofing

Passive fire protection is an important part of a buildings construction. These products afford the occupants of buildings a barrier in terms of time before the spread of fire and smoke and thereby saving lives. We offer certified industry products that comply with current building regulations.


We understand that one of the major challenges for designers, engineers and construction companies alike is to protect buildings from the damaging effects of water. Our philosophy recognises that while waterproofing can be a relatively minor component of overall construction costs, it is a vital ingredient to successful project completion and determines the buildings longevity. We also understand that our clients are looking for ?tried & true? systems, and that one of the critical ingredients of any system is the installation. We strive to offer the most technically advanced systems to waterproof your structures externally.

Radon Barrier 

Radon gas is considered the silent menace. It contributes over 50% of the radiation dose received by the Irish public every year. The average Irish person receives at least 1,500 times more radiation from radon that he/she receives from Sellafield. It is therefore, easily, the single biggest source of exposure to radiation encountered by the public. To counteract radon gas continuous thick plastic sheeting is laid down to prevent radon from getting into the house. The barrier is sealed by a hot welder which offers a greater resistance to tears along the joints. The barrier is then transported to site and fitted by our trained staff.

Do not block vents with insulation, and keep insulation at least 3 inches away from recessed lighting fixtures
