continuous exterior insulation over stucco retrofit
A homeowner with a 1993 stucco house in Utah is asking a building-science forum about a wall upgrade: adding two layers of 1.5-inch rockwool insulation (a mineral-wool board that lets moisture pass through) over the existing stucco, then furring strips, then new cement-board siding. The idea is to wrap the house in a continuous layer of insulation on the outside, which cuts down on the heat loss that happens through wall studs and framing. The questions raised are technical ones that matter for anyone considering this kind of retrofit. One is whether the old stucco itself can serve as the water-resistive barrier (the layer that keeps rain out of the wall), since no new barrier is planned. The other is about moisture: the house already has plastic sheeting behind the drywall on the inside, so adding a vapor-blocking rigid foam on the outside too could trap moisture inside the wall with nowhere to dry out. Using a permeable product like rockwool instead is meant to let the wall dry toward the outside. For homeowners with older stucco homes, this is a reminder that re-insulating the outside of a wall is not just a matter of picking a thicker board. The existing barriers already in the wall — vapor sheeting, old stucco, tar paper — all affect whether moisture can escape once new layers go on. Anyone looking at a similar project on a stucco house would want to look closely at what is already inside their own walls before choosing materials.
Roofing Polyiso for Continuous Exterior Wall Insulation
A homeowner in Utah is planning to insulate the outside of a 2x6 wall (cellulose insulation inside, taped Zip sheathing, rigid foam board, then a rain screen gap and siding). They asked whether rigid foam board made for roofs, specifically polyiso sold for roofing use, could work on walls instead of foam labeled for walls. The roofing version costs roughly half as much. Two brands came up: Elevate Isoguard GL and Carlisle InsulBase. Both have a fiber facing rather than foil, which lets some moisture pass through, something the homeowner likes because it lets the wall dry out if it gets damp. One reply pointed out that this swap has come up before in building circles. The facing on these fiber-faced boards is usually fiberglass-reinforced paper, and it does not hold up well once it gets wet, even when it sits behind a rain screen (the gap and furring strips that let air and water drain behind siding). People have used roofing polyiso on walls anyway. Workarounds mentioned include coating and taping the facing with primer to turn it into an air barrier, or adding a separate weather-resistant barrier over the foam to protect the facing from moisture. For a homeowner, the takeaway is that cheaper roofing-grade foam board might work on a wall, but the facing's durability against moisture is the open question, and no firm verdict was reached in the discussion.
