The soundproofing quality in a building depends on the suitability of the treatment of several elements that are providing the users with a comfort level resulting from the building protection against internal and external noise.
Since over a decade ago ChovA has been developing highly reliable quality products for the building acoustic insulation and is a leading company in the field of the soundproof od residential buildings, health and educational centers and commercial premises.
AIR SOUND PROOFING
HIGH DENSITY VISCOELASTIC MEMBRANES
MULTILAYER COMPOSITE PRODUCTS
The VISCOLAM is a high density viscoelastic membrane designed to improve acoustic insulation.
Recommended use:Reinforcement of the insulation of Dry walls (gypsum boards). - Improves the total mass with minimum increase of the thickness. - Improves vibrations attenuation between gypsum boards. - Improves low-frequency sound insulation.
The VISCOLAM AUTO-ADHESIVO: The self-adhesive VISCOLAM is easy applied and has two main advantages: Easy handling size of 1,2 x 1m that fits perfectly the standard size of gypsum boards resulting thus in minimum loss of product.
The ChovACUSTIC FIELTEX composite product is a textile felt of 16 mm thermally adhered to a high density viscoelastic membrane. This combination of absorbent and insulation characteristics result in a product highly efficient that reduces airborne noise in a wide range of frequencies. Recommended use: - Soundproof of traditional building elements in new buildings or refurbishment. - Acoustic insulation drainpipes or air pipes.
The ChovACUSTIC PLUS FIELTEX is a multilayer composite product consisting in two layers of polyester open fibers being asymmetric in density and thickness and that are thermally adhered to a 4 mm high density viscoelastic membrane. Recommended use: - Insulation of double leaf partition walls. - Acoustic insulation of Dry lining sysyems. - Soundproof insulation of ceilings.
ChovACUSTIC LR 70/4 board is multilayer composite product consisting in a 40 mm rockwool board of 70 Kg/m3 density, thermally adhered to a high density viscoelastic membrane. Improves the airborne noise insulation. Recommended use: - Soundproof insulation of ceilings. - Improves the insulation of modular systems (screens, laminated plasterboards...) - Can be installed directly onto the wall or adjusted to walls studs.
