ROCKINSUL Building Rolls is used mainly in pre-engineered buildings for roofs and walls to achieve excellent thermal and acoustic insulation. It can be used for both under purlin and over purlin application on the roof.
Stone wool fibers in ROCKINSUL Building Rolls are fine and uniformly distributed that ensures excellent & uniform thermal resistance. The stable stone wool fibers bonded with thermosetting resins are light in weight, strong and resilient.

Facing Types
ROCKINSUL Building Rolls are available with ALG and FSK facings, which provide an efficient vapour barrier. The product is also available with kraft paper facing.
Working Temperature
Fiber : Up to 750 °C
Facing : 100 °C
At temperatures in excess of 230 °C a limited migration of binder may occur in the insulation in contact with the hot face. This does not impair the insulation performance.
Acoustic Performance
ROCKINSUL RB Slabs achieve excellent acoustic performances (sound absorption coefficients, sound insulation, and impact sound isolation) when tested in accordance to various relevant ASTM standards. RB Slabs achieve Noise Reduction Coefficient (NRC) values up to 1, when tested in accordance to ASTM C423.
Fire Safety Performance
Unfaced ROCKINSUL Building Rolls are non-combustible when tested in accordance with IS 3144, BS 476 (part 4), ISO 1182 and ASTM E136 and are classified as Class A1, in accordance with European norms. Unfaced, FSK and ALG-faced ROCKINSUL Building Rolls have the following fire safety rating achievements:
- Class 1 surface spread of flame in accordance to BS 476 (part 7)
- Class 0 in accordance to the BS 476 (part 6 & 7) and to British Building Regulations.
- Surface burning characteristics in accordance to ASTM E84 / UL 723
a: Fire Spread Index: Less than 25
b: Smoke Developed Index: Less than 50 Smoke Developed Index : Less than 50
Applications
ROCKINSUL Building Rolls are commonly used on the walls and roofs (under and over purlins) of pre-engineered buildings, pre-fabricated houses, poultry farms and HVAC ducting.
