Contractor built our chimney chase for the metal chimney vent to be installed whenever the installers decide to install the rest of our fireplace, hopefully within the next year. Anyway, our empty chase basically a hollow wooden structure developed a major problem with the warm temperatures (above freezing) yesterday. There was a thick layer of frost and ice on the inside walls of the chase and it melted, thus sending streams of water into attic, soaking thru 16" of insulation, and dripping into the house.
Numerous buckets later and hoisting a heater up into attic to melt the frost and dry the wood we sealed the hole to the chase at the roof boards with insulation and visqueen.
We have never had a frost problem on trusses or roof boards at any time in the attic prior to this, why now?
Does the chase need to be insulated, if so can it be done on the inside, and with what? The chimney vent pipe is 8" diameter and the chase is 24" sq. Insulation can not be added to outside as allowances were not made to allow for this plus the siding to be installed.
Builder says the chase does not need insulating and the problem of frost will not occur with the chimney vent inside. My parents have a sheet metal brick chase and it is not insulated and they have not had frosty chases.
This project is a TRUE test of patience and we are nearly ready to rip the thing out and demand our money back from dealer!:angry2:
Here are 2 photos of the chase, 1st during build (2 months ago)
2nd waiting waiting & waiting for the chimney.
