Insulation Material

We manufacture Fiberglass Wool Insulation using bonded glass fibers. Our product is Known for it’s thermal and acoustic insulation and is available in the markets with or without Al Foil.

Some of the application areas of our product are:

• Under deck Insulation

• Over the false ceiling

• For Ducting

• Available Thickness-25, 40, 50 mm

Rockwool Slab Insulation semi-rigid and rigid boards manufactured from stable rock fibers bonded with a minimum quantity of thermosetting resin binder. ROCKWOOL RB slabs are capable of withstanding extreme temperature up to 750 °C and are light weight, strong, resilient, easy to handle, and easy to cut to suit intricate shapes.

Facing Type- Rockwool Slab Insulation are available unfaced or with facing of ALG, glass reinforced Aluminium Foil/ Kraft paper laminate facing (FSK), Black Fiber Glass Tissue (BGT)

Acoustic Performance- Rockwool Slab Insulation 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 Saferty Performance

Unfaced ROCKWOOL  RB Slabs 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 RB Slabs 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)

• Resistance to vibration and jolting
• Durable / Long life.
• Vermin proof
• Non corrosive.

• Clean the surfaces wherein insulation to be applied.
• Apply a coat of cold setting adhesive CPRX compound or hot blown bitumen 85-25 grade and fix wooden battens or GI or Aluminium channels of height equal to the thickness of insulation to be used, 50mm for AHU and 100mm for D.G. Set rooms.
• Frame work to be spaced at 600 x 600mm C/C for the walls and ceiling.
• Twiga Fiberglass in specified density and thickness is placed in position within the framework and covered with white or black non woven Fiberglass Tissue (FGT).24G perforated aluminium sheet with approx. 20-25% perforations is placed in position over the insulation and FGT with help of self tapping screws onto the framework.
• Plain aluminium beading 25mm wide, 3mm thick is then placed at the joints of the perforated sheets and secured to the frame work by means of self tapping screws.
• Acoustic lining of walls shall be terminated 150mm above the finished floor to prevent damage to insulation due to accidental water logging in plant or AHU rooms.

• Fix 50 x 50 x 150mm wooden pegs at interval of 1m x 0.6m x 0.6m with the help of screws.
• Fix chicken wire mesh 12.5mm x 22 G of hexagonal construction over the pegs in order to create an air space of 50mm with the wall.
• Fabricate and fix 0.63mm thick ‘Z’ type GI channels at intervals of 1m x0.6m C/C.
• Fix Twiga Insul of required density and thickness over the pegs to the channel.
• Spread a layer of Black non woven Fiberglass Tissue.
• Fix aluminium or GI perforated sheet having at least 20-25% perforations with brass screws.
• Fix aluminium beading 25mm x 3mm thick over joints with self tapping screws for the walls and roof area.
