Roxul

Applications:
This product is designed for commercial, industrial, and residential buildings as a fire stopping insulation. Ideal for filling:

• Perimeter gaps between concrete floor slabs and exterior wall systems
• Around conduit pipe and duct openings through walls and floor slabs
• Between fire walls and ceiling slabs

Roxul SAFE® is used in conjunction with a fire sealant to prevent passage of fire and smoke.

Properties:

• Non-combustible Roxul stone wool insulation with melting point of approx. 1177°C (2150°F)
• Does not promote smoke or flame spread when exposed to flame
• Minimal shrinkage to maintain critical line of defense against fire
• Low thermal conductivity
• Water and moisture resistant; does not absorb moisture to maintain insulating value
• Does not rot, promote mildew, fungi, or bacteria, or sustain vermin
• Can be faced with reinforced foil facings
• Earns LEED® points – talk to Roxul’s LEED® Accredited Professional

Roxul Sound-Absorbent

The unique non-directional structure of Roxul Insulation stone wool content is denser than traditional insulations. This effectively reduces airflow and essentially, sound transmissions. Higher air flow resistivity means better sound attenuation. Excellent overall sound control is further achieved with several Roxul insulation products as the density of the stone wool content is increased – such as in our rigid and semi-rigid board products.

What is a good sound environment?

Noise should be dampened to such an extent that it no longer interferes with the activity you were set out to do. Just 30 dB(A) is disturbing to sleep. Noise with sound levels of 35 dB(A) or more interferes with the intelligibility of speech in smaller rooms.

Even lower background levels are needed for adequate speech intelligibility for vulnerable groups - such as the hearing impaired, the elderly, children in the process of language and reading development, and individuals who are not familiar with the spoken language

Rooms with many hard surfaces may result in disturbing ‘echo’ which must be avoided. A reverberation time below 0.6 seconds is desirable, even in a quiet environment.

A 10 dB difference is perceived by the human ear as a doubling (or halving) of the audible sound.
