EPS Application

EPS external wall insulation
EPS external wall insulation is an accepted way of adding thermal value to the outer face of most external walls of buildings.
Its versatility enables it is to be used with a variety of finishes including plastic weatherboarding, cladding, tile hanging and reinforced-render systems.
EPS external wall insulation when used on the external face of masonry wall maximizes the natural thermal capacity of the wall and assists in the reduction of thermal fluctuations.
Given that heating and air- conditioning interior rooms consume vast amounts energy and accounts for approximately 80% of total energy consumption with 30% being lost through un-insulated walls, external wall insulation offers a highly cost effective way of reducing this loss.
Exterior insulating and finishing systems
For 30 years, the stucco- like appearance of exterior insulating and finish system (EIFS) (fig 6-23) has given commercial buildings high curb appeal, broad design and color flexibility, low maintenance and durability, and high energy efficiency. In more recent years, the residential marketplace has begun enjoying the benefits of EIFT, as well. But inn some residential applications, there had been a problem.
Moisture that had passed through windows and door openings was trapped behind the EIFS exterior; in some cases the moisture caused rotting o the wall studs and sheathing. The problem was summarized in the New York Times article, “some users of artificial stucco find headaches are real”, ; “the trouble is that EIFS are too waterproof. Water that gets trapped behind the EIFS exterior has nowhere to go and begins soaking into studs or plywood sheathing.”
For this reason many EIFS manufactures have innovated moisture – mitigation systems that effectively prevent moisture buildup on the rare occasions that makes its way behind the EIFS exterior. .
