PlastaBlock™ XRV & Block System

PlastaBlock™ is a polystryene block system that will provide an R-Value of 1.0 whereas 20 mm of insulating plaster will provide only 0.2 R-Value, yet the cost of both are very similar.
From 31st October 2007, tougher thermal performance standards apply to all new houses and buildings. The most difficult houses in insulate masonry homes which maximizes the benefits of the thermal mass. The insulation properties of the 40 mm EPS sheet will produce an R-Value of 1.0, which will exceed the building code changes.
