Dimensionally Stable
Mineral wool boards not being extruded, foamed, or expanded, have no stresses built into the product, and as fibrous materials are extremely stable. (Linear shrinkage 0.19% ASTM C 356)
Non-corrosive to Steel Decks
Being slightly basic, (pH 9) mineral wool boards pose no corrosion threat to metals.
Resists Mold, Fungi & Bacteria
As mineral wool is non-organic, there is no support for bacterial or fungal growth.
Stable R-Value
Having no gaseous blowing agents, the initial R-value is also the aged R-value. Mineral wool boards have an R-value of 4 per inch (RSI 0.70 per 25 mm).
Sound Absorbent
Mineral wool boards, being fibrous insulation material, absorb sound extremely well. As they are comparatively dense, (11/lbs per cubic ft) their resistance to sound transmission is excellent.
Environmentally Friendly
Mineral wool boards have approximately 40% recycled content (steel slag). They are chemically and dimensionally stable, are safely disposed of, and do not give off toxic gases or deadly fumes when subject to fire.
Moisture Resistant
Moisture has no adverse effects on mineral wool, moisture absorption is very low @ 1.1% by wt. (ASTM C 209). The binders in Protec products are waterproof.
Will Not burn
Mineral wool board is noncombustible, and with a melting point far above normal fire temperatures is virtually indestructible. It will not therefore add fuel to an existing fire, as most other insulation materials will.
