Comments on the most important Recytex / Silentium products
RECYtherm is a very lightweight voluminous non-woven for thermal and acoustic insulation of ships hulls. For the surface we use a steam- diffusion- barrier with a heat- reflective base. RECYtherm is also suitable for the sound insulation of smaller engines, especially if you desire a low weight.
RECYvib is a very thin (7mm) vibration absorber, that can be installed highly effective in very small places. Due to its mass, RECYvib reduces structure- borne- sounds very effectively and prevents them from spreading.
RECYguard is our bestseller. The combination of a soft non- woven layer with a vibration absorber achieves a very effective sound dampening over the entire range of frequencies.
RECYcombi reflects particularly high requirements for sound insulation and the optics. The honeycombed- shaped surface creates a higher proportion of diffuse reflection of the impinging sound waves while the additional layer of non- woven provides a better insulation. At the same time, the honeycombed design brings out a high quality look, especially inside bigger engine rooms.
Our sound absorbing products (RECYtherm, RECYguard, RECYcombi) are standardly delivered in 3 different thicknesses and with two surfaces:
W 300: The middle layer of non- woven is about 1cm thick.
W 600: The middle layer of non- woven is about 2cm thick.
W1300: The middle layer of non- woven is about 4cm thick.
A: The surface consists of a plastic foil with a silver, washable surface.
GA: The surface is made of a highly robust glass- fabric, covered by an aluminized foil. We recommend the usage of this surface under high mechanical or thermal exposure (e.g. insulation close to the exhaust manifold).
The products that have been certified in accordance to CE- Standards carry the sign of our certifier ECB (European Certification Bureau) on their fact sheets. The certification also confirms passing the burning test according to DIN EN 4589-3.
During the Apamat- sound- measurement the sound level reduction is determined when passing through the insulation material (which is noted on all of our fact sheets). So this level confirms the sound level reduction outside the engine compartment. It can be stated approximately that a reduction by 3- 4 dB leads ti a halving of the subjectively felt noise.
