Premier insulations have been installing attic insulation in both new build and retrofit for over 30 years . So what is the best type of attic insulation is best for my home, the answer is there is no best type, it is what is the most suitable type of attic insulation for the particular project in mind.
We must remember that when dealing with say domestic homes there are various build types which require a different approach in terms of insulation. Whilst the end objective is always the same of achieving the best thermal values the type of insulation fitted will very. Take for instance a dormer type property , the insulation here is extremely important as the upper living areas are very vulnerable to heat loss in the winter and overheating in the Summer. We would always recommend a Sprayfoam type insulation here preferable a certified product such as PurAcell and applying the Sprayfoam from the eaves or wall plate up to and across the collar ties and down to the wall plate on the opposite side providing a complete airtight seal to the full roof structure . Prior to spraying a ventilation card should be fitted to the underside of the roof membrane allowing a 50 mm gap for the provision of ventilation . Adequate vents should be fitted at soffit level to provide a continuous 250mm air flow up behind the vent card and migrating through vent tiles fitted above the collar ties at high level.
This system ensure that the habitable area of the house benefits from superior insulation and air tightness whilst the roof is breathing naturally ensuring no stagnant build up of air pockets and ensuring longevity of the roof structure.
Always ensure that Sprayfoam systems are not only nsai certified but installed by a registered and certified company. Premier Insulations are industry leaders in the supply and installation of all attic insulation systems. Avoid cold winters and overheating in the summer!
