Mineral wool retains its condition a lot better than fiberglass or cellulose. It won't settle within walls, leaving chilly gaps along the top plate. If there’s air infiltration, moisture will never compromise or degrade its thermal general performance; and the material supplies no foodstuff to assistance microorganisms.

Thanks Martin. I hope to hear from Mark or any person else acquiring experience with or feelings on applying this approach. Am I right that mineral wool also has the advantage of currently being less at risk of termites and ants than foam when exposed to soil?

They need to have similar R values for a similar thickness, at the very least that’s what I’ve normally noticed. Rockwool is a bit much less dusty than thermafiber to put in, but Other than that, There is certainly very little distinction between the two goods.

EIFS structures and PERSIST buildings conduct incredibly properly, so long as the designer and installer approach for rain, and don't put in interior polyethylene.

This venture happens to be challenging (at the very least to me). It started out for a venture to replace the cedar siding and become one of restoration for several parts of h2o damaged plywood with entrance points for numerous vermin to wipe out the present fiberglass insulation. A lot of the h2o-damaged areas make sense to me (about windows and areas of badly flashed roof/siding junctions) - nonetheless the drinking water injury in the midst of the home very likely transpired from rain/wind, I believe - and I would like to body the house in a method this is more unlikely to take place Later on - (Tyvak and asphalt/felt employed ahead of, I don't Believe a rainscreen was in place).

No matter price tag (not Substantially of distinction listed here in Upstate NY for very similar R-values), and all of The explanations expressed by Robert File. in favor of mineral wool, You can find 1 crucial part not a soul has mentioned. The sound deadening component mineral wool provides to the table wins hands down more than fiberglass. We're builders who have already been living in a zero Vitality more info residence for six several years that was insulated with Rockwool; R15 x 3 within the walls.

Like a dense, fireproof substance, mineral wool has normally played an essential position in improving the fire efficiency of structures. It's not only fireproof but also shields the setting up by reducing warmth transfer and the spread of fire within framing cavities.

We first regarded as working with rock wool batts, since they ordinarily have the exact same thermal worth for each inch since the denser board solutions, though becoming cheaper and even more readily available.

Which is solidly in the middle of Course-III vapor retardency, similar to that of ordinary interior latex paint. The housewrap also could well be delivering a minimum of some degree of capillary split to Restrict the amount of wicking of floor humidity in the fiber.

After i initially fulfilled Chris Gleba and Kris Erickson in December 2011 to discuss their ideas to get a deep energy retrofit, Chris told me that he were transforming his modest two-bedroom house in Lowell, Massachusetts, for more than 10 several years.

With all of these good attributes, we felt devoted to applying it for this project. Most rock wool board and batt items regular all over R-four.two for every inch, And so the challenge then became: How would we cost-efficiently wrap about 6 inches of rock wool insulation on the exterior of a wood construction even though anticipating some way to attach the siding?

I'm happy the Heco Topix Therm labored on this undertaking. I remember the mineral wool thickness was suitable at the sting on the operating array exactly where it would not compress the MW. It won't seem like you had far too much problems.

That makes sense for stability. I dislike to pull the 1999 double panes out as These are silicone caulked in place And that i'll must someway make area to get a deep window buck (want innies) to include two much more outer levels of insulation (old 2x4 partitions in NE WI are Chilly).
