Roxul Insulation better acoustically and fire resistance than glasswool


When we talk about Roxul insulation, let us first summarize what Roxul insulation means and what it is made of. Roxul insulation is mineral fiber insulation which finds its foundation in a rock base; it is basically made of Basalt rock and Recycled Slag. Further clarifying the constituents of roxul insulation, Basalt is a volcanic rock, found in abundance in the Earth while slagging a by-product of the steel and copper industry. Together these minerals go through a process of melting and then they are spun to form fibres.

Roxul insulation has many benefits this type of solution offers in homes as well as industrial use. First of all, roxul insulation is moisture resistant however it is still vapor permeable. When the insulation by any chance gets wet or becomes damp, on the event of becoming completely dry, it regains its original performance features. Secondly, roxul products are totally inorganic in nature; this means that there is zero chance of molds growing on the surface since there is an absence of food source for the mold to grow. When roxul insulation was tested to pass a test-ASTM C1338 which is a standard test for the determination of fungi resistance, the material cleared the test with absolutely no fungal growth.

Roxul is the best for installation when taking into consideration wall insulation as well as roof insulation. The reason for this is that Roxul insulation can aid in the lessening airborne sound with the home, commercial or industrial environment. And the reducing effect on noise is much amplified when Roxul is used for both wall insulation and roof insulation as opposed to its use in only one of the surfaces.

Likely causes of sound transmission can take place between connecting floors, ceilings, walls and through electrical receptacles as well as furnace vents. Most of the sound inside the house are sound travelling in the air because of voices, music, ambient noise and other such sources. Impact sound, on the other hand, occurs as a consequence of falling objects and foot traffic. When the aim of insulation procedure is to reduce the impact sounds, additional insulation measures such as a sound absorbing layer of Roxul in between the joists and sub floors is a suitable step to take. If you are looking for a specific STC (Sound Transmission Class) rating you can confirm the specifications with the Roxul team and they will be glad to guide you in the direction of the most appropriate home insulation.

A STC (Sound Transmission Class) rating is a number rating of an assembly’s capability to resist airborne sound transfer at diverse frequencies. Commonly, a higher STC rating will block more sound from diffusing through a partition wall or ceiling. You can gain more information on the STC features from Roxul. A commonly asked question in this regard is, whether the doubling of Roxul insulation will lead to doubling of the STC value; this is not the case since the value of STC as an STC-rated assembly incorporates all components of the structure with the insulation being one component of that system.  Doubling the insulation will enhance the STC rating to some extent however it will not double it and to define by how much the value will raise, you can get in touch with Roxul for a more detailed view pertaining to acoustic insulation.

Another major benefit of using Roxul insulation instead of glass wool is the fact that it is a non-combustible material; it has a very high melting point of upto 2150 degrees Fahrenheit. This means when looking for home insulation mainly with the purpose of keeping safe from fire, this is the right choice and also can be put to use in the industrial scenario where machinery or equipment is prone to cause high temperatures and thus there is a chance of fire.

Considering if there is any “off-gassing” caused from the Roxul material, the answer is a straight no. “Off-gassing” is a word that came into being when blowing agents were used in insulation materials and Roxul does not include any kinds of blowing agents in its insulation provision. There are also certain different varieties available in the Roxul insulation; the main difference is that of density and the batt size. One type is chiefly used for acoustical and added fire resistance in interior wall insulation and the other variety which offers lesser density is used in applications requiring a thermal value. The latter is well suited for use as exterior wall insulation and also attic insulation.

As many companies and organizations are required for their buildings to pass the building code inspections, it's one aspect gaining significance with regard to the use of insulation materials. With the use of Roxul insulation, any building can pass building code inspections as Roxul meets the standard for Mineral Fibre Thermal Insulation for Buildings and also the standard specification for Mineral-Fiber Blanket Thermal Insulation for Light Frame Construction and Manufactured Housing. Thus Roxul insulation meets all criteria needed for buildings in the Canadian and United States residential codes.

Roxul insulation is quite beneficial for industrial use as well; surface temperatures which have a raised temperature of 60 degrees and above may lead to burning of the skin when contact occurs. Roxul however, is quite safe as an insulation material in the situation of high temperature or in the occurrence of fire. It does not promote flame speed and there is no release of harmful gases or fumes. It is suitable to meet all the significant factors for insulation such as protection of personnel, heat loss, process control, frost protection, reducing carbon dioxide emissions as well as acoustical performance.
