Is safe and sound the same as Comfortbatt?
S&S are the same as the "comfort batt" they look identical but according to Roxul are not even that close but are made of similar material.
What is the difference between Roxul and ROCKWOOL insulation?
Fairly recently, Roxul Insulation in North America took on the same name as its worldwide parent company - Rockwool Insulation. The same mineral wool is still offered here in Canada, which many homeowners continue to use to insulate and upgrade their homes.
Does Roxul safe and sound have an R-value?
33) What are the R-values of AFB® and SAFE'n'SOUND®? Interior insulation products do not require an R-value and as such, we do not brand our interior insulation with this information. 34) Where can I find your Safety Data Sheets?
What is the R rating of ROCKWOOL safe and sound?
Rockwool has excellent heat retention. While fiberglass insulation is capable of offering an R-value of about 2.2 to 2.7 per inch of insulation, Rockwool has an R-value between 3.0 to 3.3 per inch of insulation.
What is the best soundproof insulation?
Fiberglass is undoubtedly the most effective, versatile insulation for soundproofing. Between fiberglass, mineral wool, and cellulose insulation, fiberglass consistently has the highest STL, Sound Transmission Class rating.
How thick should Rockwool be for soundproofing?
The thickness of Rockwool slab acoustic insulation vary. Our customers can choose from 25mm, 50mm, 75mm, 100mm, and 140mm thicknesses. The government recommends using 250mm thick rock wool insulation in loft spaces to cut your energy bill by up to 20%.
Does higher R-value mean better sound proofing?
Higher R-values indicate more effective insulation. Any type of insulation you add to save energy will help somewhat to soundproof the walls, but you need additional improvements for significant noise-dampening.
What are the disadvantages of Rockwool?
The only disadvantages of Rockwool are that it is not biodegradable and can be slightly more expensive than similar insulating materials like fiberglass and cellulose.
Is a higher R-value better for soundproofing?
Is a Higher R-Value Better for Soundproofing? A higher R-value isn't better for soundproofing. Instead, a higher R-value indicates a material's ability to insulate or retain heat during the cold months. However, you can augment your existing insulation with materials that work better for soundproofing.
Can Rockwool damage your lungs?
Prolonged Exposure Risk of developing chronic diseases of the lungs such as pulmonary fibrosis, lung cancer and pleural mesothelioma also have shown to increase with long-term rockwool exposure according to the Center for Disease Control.
What R-value insulation do I need for soundproofing?
While soundproofing your room, you might want to include R-13 insulation in the walls and R-19 in the ceilings. You can use cut-to-size batts which match the standard joist and drywall measurements.
Which R-value should I use?
Depending on where you live and the part of your home you're insulating (walls, crawlspace, attic, etc.), you'll need a different R-Value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces.
What are the disadvantages of Rockwool?
The only disadvantages of Rockwool are that it is not biodegradable and can be slightly more expensive than similar insulating materials like fiberglass and cellulose.
Does roxul need a vapor barrier?
roxul Comfortbatt is an unfaced semi-rigid batt insulation and a vapor retarder may be required by building code depending on the geographic location of the building. The use of a vapor retarder will limit the amount of water vapor that will move to the outside wall – reducing condensation in the wall assembly.
Is mineral wool insulation the same as Rockwool insulation?
Both 'Rockwool' and 'mineral fibre' are terms that are often used interchangeably, but essentially, they share the same material make-up – stone wool – where melted natural rock is spun into long fibre strands, captured and condensed into a high-density mat.
Is Rockwool worth the extra money?
In many ways, mineral wool is a superior insulation product. It has a higher R-value per inch compared to fiberglass, about a 22-37% higher R-value. It contains 70% recycled material, making it a greener product than fiberglass at 20-30% recycled material..
How thick is Rockwool safe and sound?
From Rockwool/Roxul tech support: "ROCKWOOL SAFE’n’SOUND® is available in a 3” thick batt for both wood and steel stud sizing.
Why is Safe and Sound a bit htinner?
The reason Safe n' Sound is a bit htinner is so that it leaves an air gap at once side and doesn't contact both sides of the wall. That air gap helps with sound isolation. If you maintain the air gap, then you're probably close with your math in terms of sound attenuation, but I'd test it first before doing a large scale build with an untested assembly.
How much R/inch is rock wool?
At comparable density it's R value will have about the same R/inch. For rock wool that is about R4.3/inch, so at 3" you'd get ~R13 or maybe a bit less compared to R15 @ 3.5". But if there is an air gap the potential convective bypass around the batt can cut into thermal performance, which is why you DO want the cavity completely filled if it's for insulation rather than sound abatement.
Why is fiber in direct contact with wallboard?
That is because when the fiber is in direct contact with the wallboard on both sides it increases the mechanical coupling between the sides, transferring the sound vibration picked up by one sheet of wallboard and transferring some of that energy to the other wallboard.
Is Rockwool Comfortbatt faced?
Rockwool Comfortbatt isn't faced either. There's lots of (better) ways to get a vapor retarder into the wall assembly that doesn't rely on the batts being faced.
Does Rockwool insulation have an R value?
According to Rockwool's website "Interior insulation products do not require an R-value and as such, we do not brand our interior insulation with this information. " If it's strictly being used for sound control, it makes sense to use the product designed specifically for that application.
Is Roxul glass good for exterior?
"It's not appropriate for exterior applications because it's not faced (no moisture barrier.)".
