The professional insulation for noise absorption.
ArmaSound is a versatile acoustic absorber designed for use in a variety of different acoustic applications. A high performance sound absorber which also offers additional transmission loss performance and both vibration damping and isolation properties, ArmaSound is the result of 4 years of research. The acoustic properties of ArmaSound vary depending on formulation, density and thickness. The best results will be observed by selecting the most appropriate product grade for the type of noise in question. ArmaSound can also be engineered to meet specific requirements by optimising its absorption behaviour to match particular problem frequencies.
Sound Absorption
Open cell structure with complex pore geometry allows for effective absorption of air-borne sound across a broad frequency range
Unique combination of physical properties allows absorption to be maximised at key nuisance frequencies.
Sound Transmission Loss
Relatively high density and high flow resistance offers benifi cial sound tranmsission loss properties.
May be suitable for use as an alternative to complex "foam-barrier" multilayers.
Vibration Damping and Isolation
Visco-elastic properties help dampen or deaden resonance effects in metal panelwork (e.g. enclosures or ducting) which helps to reduce "re-raditaion" effects.
Reduces structure-borne noise transmission when used as isolation pads.

Elastomers have two major properties:
- they are practically incompressible;
- when subject to shear, they have a very low modulus which means that show small reactions for high amplitudes
The shear and compression properties of elastomers enable laminated assemblies to be used as conventional bearings:
- immobilization and load bearing capacity in certains directions;
- capacity to move in directions perpendicular to the previous one.

High level of acoustical and thermal insulation. The foam has high working temperature. The low thermal conductivity and the high sound absorption
coefficient make the material specially suitable for the insulation of all types of hull and when lightweight is required. The final product is easy to cut in the right dimensions and can be easily fixed with glue or pins. The foam can be hydrophobic (H version) and covered with different foils aluminium, hydrophobic & oleophobic vlies, adhesive...). The grey colour variation has no effect on the product performances.

For over fifty years the Klegecell name has been synonymous with high performance foams for structural and insulation applications. Throughout this time Klegecell has been steadily enhanced.
Today Klegecell R is typified by its extremely high strength to weight ratio, excellent thermal and acoustic insulation properties, low water absorption and good chemical resistance.
Klegecell R can be supplied in flat sheets, in grid-scored form and as kits and is approved by all major classification societies. To access the Klegecell brochure (250k Acrobat pdf file), please click on the title above. Please click here for the Klegecell R data sheet.

High level of acoustical and thermal insulation, Willnotec AB H is built up out of the highest quality of materials and is CE qualified (hydrophobic and oleophobic foam). Due to its combination of heavy layer and opencell foam, we created a lightweight product that performs both sound absorption and insulation. Thickness of foam as well as heavy layer can be tuned in order to achieve the defined target . The reinforced aluminium covering is water and oil resistant, and easy to clean. Other coverings like nonwoven vlies are also available that improves acoustic absorption at medium and high frequencies. Final product is easy to cut and the standard version is delivered with an adhesive layer (+ A2) but can also be easily fixed with glue or pins.
