  • Eliminate moulds, mildew and condensation.
  • In todays climate the importance of a correctly insulatated home cannot be overstated – in the winters of 2010 and 2011 record low temperatures were reached for a sustained period and home heat costs continue to rise.
  • Correctly installed installation will reduce heat loss through the fabric of the building thus increasing the level of comfort for the home owner in addition to reducing heat bills.
  • External wall insulation is the most effective way to insulate your home to eliminate all thermal bridging (cold bridging- gaps with no insulation) and achieve a uniform level of insulation through your home.
  • By insulating externally there is no disruption to the household or re-decorating the interior of the house as is the case after insulation.

How does it work?

By insulating externally a layer of insulation wraps around your walls and slows down the heat transfer
from inside to outside, thus allowing a heat reserve to build up in existing walls, much like a storage heater, as the temperature drops the stored heat is released back slowly into the house so during a cold winter all you need to do is rotate your heat for a few hours a day.
It acts like a blanket around your house.


Depending on your current U-Value usually 100ml of grey insulation is required to achieve a U Value of 0.27.
Window and door reveals are installed.
Window sills are partially removed and insulated window sills are installed.
Glass fibre mesh is then installed imbedded in a layer of base coat, when cured the building will be primed and finished in an accrylic texture and colour of your choice.
The insulation system comes with a 10 year warranty and your home will have a maintenance free finish.
