EIFS cladding systems
EIFS cladding systems
(OP)
To save googling for those who don't know, EIFS means Exterior Insulation and Finish System. It is a relatively new facade material in Australia. I know there have been lots of leakage problems in the US and some other countries with these systems. Apparently, common practice has been to directly apply the system to the structural wall, so the waterproofing is a barrier approach. Anyone have experience with making this into a drained wall by creating a cavity by battening over the sarking before the polystyrene sheets are installed?






RE: EIFS cladding systems
A typical drainage layer consists of a polypropylene mesh attached to sheathing/backing substrate and air barrier. The insulation is applied over the drainage mat.

I've run into contractors who won't touch the stuff. It's not a bad product, although it has its quirks. If they're not familiar with it in your area, do you want to be the one experimenting?
RE: EIFS cladding systems
I have experience with DryVit and Sto systems. The Sto liquid applied barrier seems to be pretty good, but depends on proper application (as always).
I would not specify either (or any other EIFS for that matter). I'm just not a fan and have done too many water intrusion failure investigations to have any level of comfort that they will work for the long term.
RE: EIFS cladding systems
This is one of the companies who are marketing the system here. A lot of it is being used, so maybe a lot of work for water intrusion investigators in years to come.

RE: EIFS cladding systems
You're right...lots of business in the future for the failures.
Do I need to open an office in Oz?<g>

I agree that "the Devil's in the details". Flashing, sealants, sealant joints, floor line joints, control joints...all can be problematic.
RE: EIFS cladding systems
I'm paying $14 per square foot which includes the mouldings and all materials. House has 2000 square feet of wall spacr. EIFS is adhered to brick with cement, then fiber glass mest, base coat and mouldings for windows. Finally finish coat. Can anyone advise where I can get this work done for $8 per square foot. Thanks.
