Jolly Board Limited

Marine Drive, Mumbai, Maharashtra

Jolly bitulex softboard is processed from cane fibre, the raw material tested and proven to provide the best resilience. Impregnated with bitumen in various percentages, it is a perfect base material for expansion joint fillers. The board's compression and recovery characteristics confirm to the u.k., u.s.a. And indian standards much above the required averages. jolly board expansion joint filler : jolly board expansion joint filler is manufactured from water resistant, bitumen impregnated, cane fibre. It is available in a wide range of sizes, both as boards & strips in thicknesses of 10 mm, 12 mm, 18 mm, 19 mm, 25 mm. Jolly expansion joint filler displays excellent resistance to compression, with outstanding recovery characteristics. The fillers are environment friendly as opposed to the environment destroying thermocoleplastic expansion joint filler.

Sound Insulation: Against impact, sound transmission to the standards of building regulations is obtained when a resilient soft board layer is incorporated in the construction.

Indian Standard 3348: Fibre Insulation Boards and BS 1142 Part 3: 1972 Insulating Board-Softboard include all available International Standards and give the procedure for sampling. They also define six tests levels which insulating board must satisfy. These are density, bending strength, water absorption, thermal conductivity, sound absorption and surface spread of flame.

Description: Composition and Manufacture: Bagasse is reduced to fibres which are then felted to form a continuous sheet. After cutting to approximate size, the sheets are passed through a drying oven. These sheets are trimmed to board sizes.

Improved acoustic properties are obtained by grooving insulating boards to part of their depth in various patterns.

Sizes generally available are:Sheets: 1220mm x 2440mm (4 x 8) and 1220mm x 1220mm (4 x 4) Thickness available are 9mm, 12mm, 15mm, 18mm, 20mm and 25mm upto 100mm.

Production tolerances: Permissible deviations in length, width and thickness from manufacturers stated size are as per those given in Table 1 in IS 3348 and Table 1 in BS 1142: Part 3, Smaller tolerances than those specified can be obtained by agreement.

Weight: Weight of boards varies according to brand. Typical weights (kg/m2) are 2.5-2.7 for 9mm thickness, 3.2-3.7 for 12mm, 4.4-5.4 for 18mm, and 6-7.5 for 25mm.

Density: Generally within the range of 230 to 330 kg/ml IS 3348 maximum is 400 kg/m3. BS 1142 maximum is 350 kg/m3.

APPEARANCES: Surface texture: Varies from smooth to dimpled.

Colour of most boards is various shades of cream and brown. Some boards are coated with a white primer for painting.

Special boards available: Painted, paper plastic or textile faced. Flame-retardant treated types are available on request.

CLIMATIC EFFECT:Jolly Softboards are hygroscopic in nature. Their dimensions change in response to changes in humidity. If these dimensional changes take place after the boards have been fixed they may cause bowing or gaps at joints. To avoid this the moisture content of board may first need to be adjusted to that of the surrounding air by conditioning. Conditioning is done by placing the boards in the room where they are to be fitted for 24 to 48 hours to attain the same moisture content.

BEHAVIOUR IN USE:The data presented in the following table gives general round values from laboratory test results.

These are normally used in Ceiling or on Pinboards or for packaging delicate material like glassware. A suitable pattern is chosen to puncture the holes in Ceiling Slabs normally 1 ft. x 1 ft. These Ceiling Tiles are fitted between the steel grid shown.
