Now lets see how fiberglass and rockwool do as far as soundproofing goes: Also known as mineral wool, rockwool is literally what the word implies: Rock fibers (volcanic rock and slag) which are spun and then given a specific shape (batt, pipe and board forms). It has a higher R-value per inch compared to fiberglass, about a 22-37% higher R-value. Then, the molten glass is pushed through tiny holes to create thin filaments. It liquefies at a temperature of 3000 Fahrenheit. However, Rockwool insulation gains further points here thanks to its mineral-based construction, which gives it a much higher melting point than fiberglass. Rockwool can withstand temperatures of up to 1000 C (1800 F), while fiberglass melts around 600 C (1100 F). Resilient Channels 5.3 3. Meanwhile, a Rockwool batt of the same dimension and rating will cost $ 0.62 per square foot. Moreover, it has been established that R-value tends to decrease for Fiberglass over time while it does not deteriorate throughout the life of the Rockwool. Withstanding temperatures up to 2150F (1177C), Safe'n'Sound is non-combustible and will not produce toxic smoke or promote flame spreading, even when directly exposed to fire. Rockwool and fiberglass are both ecologically friendly compared to other building materials. It may add a little bit of sound resistance, but nothing major.

Fiberglass insulation, or properly named glass wool (fiberglass is actually the one used for boats, etc., which is rigid), is an insulation material made fromfibers of glassarranged into a texture similar towool. Fiberglass filaments are packaged into rolls, while others are packaged into denser materials. Rock wool is a high-performing soundproofing material. Once liquidized, air or steam is jetted into the liquid under high pressure and turned at high speed. This product is available in the same form as fiberglass. Higher R-value. Simple math will suggest that a job of insulating 625 square feet with Fiberglass will cost $312 in contrast to $388 for Rockwool. Shed Insulation: A Complete Breakdown of Options, Do You Need To Put Rigid Insulation Under Concrete Slab? Your email address will not be published. Now, I share all the tips I've learned on this blog. Fiberglass insulation is, like mineral wool, made from a similar process of melting down glass and spinning it at very high speeds as they cool. So that means, for standard 24 wall mineral wool comes in R-15 batts, while fiberglass comes in R-11 or R-13. Rockwool is better for soundproofing and thermal insulation because of higher density and weight. The lower the Flame Spread index the better, since this means that the flame wont travel and spread as rapidly. It depends on the purpose.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[250,250],'soundproofpeace_com-leader-3','ezslot_12',131,'0','0'])};__ez_fad_position('div-gpt-ad-soundproofpeace_com-leader-3-0'); It is a very good sound blocking qualities. In any case, its better to prepare yourself to pay at least $ 0.10 more for Rockwool. Of course, the lower the number, the better: Both rockwool and fiberglass have a very low flame spread rating and smoke development which makes them ideal insulation material and they should help slow down the spread of fire. As far as the effect of it, I believe it will enhance low frequency control even behind double sheetrock, and Green Glue. Rockwool and fiberglass are two of the most popular types of insulation for residential applications.
