plain soft board

Jolly Softboard is soft, resilient, light coloured sheet material 9 to 25 mm thick, manufactured from bagasse (sugar-cane) fibres. Jolly Softboards are grooved or drilled to improve their sound absorbing capabilities and then used as acoustic boards. They are used for ceilings and wall linings particularly where reflected sound is to be reduced. Jollyboard is a premier manufacturer of different types of Insulation Boards including soft board. The soft boards of our company are in great demand and suitable for every requirement of soft board as well as various types of insulation boards.

Related Documents: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 9, 12, 18 and 25mm.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.
