PLS Polythene Encapsulated Pads and Rolls

PLS polythene encapsulated rolls and pads are manufactured using Isover Space Saver glass mineral fibre roll. A1 fire rating insulation, made of recycled products.
The insulation is then totally encapsulated in 200g polythene (Vapour Checked to BS 2972 / 1989) and heat sealed. This method of encapsulation provides a completely safe and environmentally friendly product, and does not detract from any of the raw materials properties, thermal or acoustic.
If the finished product needs to be cut etc on site then the normal precautions for handling the glassfibres must be adhered to.
Individual COSH sheets are available.
Normal pad sizes are 600mm x 600mm x 1200mm variations are available on request.
Normal roll sizes are 600mm or 1200mm wide up to a maximum length dictated by the glass or fibre manufacturers roll length, information on request.

Fire performance, insulation: Classified as none-combustible when tested in accordance with BS 476: part 4: 1970 (1984)
PLS Orange flame retardant pads are also available, as has recently been specified in a large supermarket chain refurbishment.

Acoustic Performance:
Rock Mineral Fibre insulation pads when used in conjunction with mineral fibre suspended ceilings can dramatically reduce sound breakout.
Typically a 50mm 45 kg/m3 pad correctly installed can achieve a upto 45db rating and a 50mm 60 kg/m3 pad can achieve upto a 48db overall rating, with a 100mm pad being able to offer upto 70db overall, in conjunction with a mineral tile ceiling.

Obviously different combinations and thicknesses can achieve different overall performances.

*Please note that these pads are compressed for delivery and should be allowed between 48 - 72 hours to re-inflate to maximum size and should be shaken when installed to allow the insulation to breathe. If kept compressed the pads may not re inflate to full size.*
