Isomat KE Fiber

What is mass loaded vinyl
Isomat KE Fiber is a mass loaded sound barrier sheet to soundproof airborne noise in buildings. Isomat KE Fiber has a jute fiber backing, which makes it easier to bond the mat with our glue. Isomat increases the mass of a wooden timber floor, light and thin walls, which drastically increases the soundproofing and sound insulation. In most cases, at least 8 dB(A) attenuation is already achieved with these sheets without additional measures. This is often experienced as halving the noise level. Isomat is a hard and heavy sheet, but still flexable, Isomat does not compress.

Applications
Isomat KE Fiber has been developed for soundproofing light materials such as plywood/underlayment of floors and walls. These sheets can be used, among other things, as a soundproofing doors, plasterboard party walls or directly on the wooden timber floor. More applications:

• Soundproofing a roof
  Isomat KE Fiber (14 kg/m²) is also suitable as an acoustic soundproofing to install to the roof boarding reducing outdoor noise such as traffic noise. The guide to soundproof a roof boarding can be found our tips page "How to soundproof a roof indoors".
• Dormer loft, dormer window
  Isomat KE Fiber is, in common with use on roof decking, also used as sound insulation in dormers. These constructions also consists of lightweight materials, plywood or plasterboard, that doesn't insulate much noise. More information about insulating the dormer window can be found on the tips page "insulating the dormer room".
• Wooden subfloor
  Wooden subfloor is also a very light structure that does not insulate noise that well. Isomat KE is ideal to soundproof floors in older houses. By providing a wooden floor with Isomat KE14, the floor becomes heavier and the insulation value increases. The complete guide on soundproofing a wooden floor can be found on our tips page "how to insulate a wooden subfloor".

Properties
Isomat KE Fiber is a recycled product made from a polymer supplemented with various fillers. It's a heavy, but also thin sheet that takes up little space. Isomat can also be used as a soundproofing core between two layers of plyewood  or plasterboard. This makes simple party walls and ceilings well soundproofing constructions. The greatest reductions are obtained if the surface on which Isomat is applied is not heavier than the sheet itself. The greater the mass of the construction, the better the soundproofing.

Assembly Tips
Isomat sound barrier sheets are easy to cut to size with a box cutter. Cut into the sheets several times and snap the sheet along the cut. Gluing Isomat to wood or plasterboard is done with Stauf Extreme Tack adhesive. The consumption is approximately 3.5 kg per 6 m². Gluing on a moisture-proof surface such as plastic, aluminium or steel is done with a contact adhesive. Provide adequate ventilation when using contact adhesives. Due to the weight of the sheets, vertical panels must be secured with, for example screws and washers or felt nails. If you are making a sandwich construction of plasterboard Isomat plasterboard (or plywood), you screw all parts to a wooden frame.
