Flame Spread Rated Fiberglass Batts

Product Description

Lightweight flame-resistant thermal and acoustical fiber glass insulation made of long, resilient glass fibers bonded with an acrylic thermosetting binder. The batts are laminated with an FSK (foil-scrim-Kraft) facing, which enables the insulation to carry a fire hazard classification rating of 25/50 or less per ASTM E 84 and also serves as an excellent vapor retarder. FSK-25 may be left exposed where codes permit.

Applications

New Construction

• Wood frame construction – residential homes and light commercial buildings
• Metal frame construction – commercial buildings

Retrofit

• Masonry walls
• Under roof decks

Performance Advantages

• Formaldehyde-free – will not off-gas formaldehyde in the indoor environment.
• Fire-resistant and Noncombustible – (see Specification Compliance). FSK-25 faced insulation can be left exposed where codes permit.
• Moisture Control – the FSK-25 facing resists water vapor transmission.
• Light-reflective – when exposed, the FSK-25 reflective surface helps maximize lighting efficiency and may reduce lighting requirements.
• Thermal Efficiency – provides effective resistance to heat transfer with R-values up to R-30 (RSI-5.3).
• Sound Control – reduces transmission of sound through exterior walls and floor/ceiling assemblies.
• Noncorrosive – does not accelerate corrosion of pipes, wiring or metal studs.
• Durable – unaffected by moisture, oil, grease and most acids. It will not rot, mildew or otherwise deteriorate.
• Resilient – bonded glass fibers will not pull apart during normal applications and resist settling, breakdown and sagging from vibration.
• Flexible – forms readily around corners and curved surfaces.
