ASTEX is a highly absorbent, fabric covered, composite panel.  It is not only decorative but also adds acoustic absorption whilst improving transmission loss and thermal characteristics.  It is constructed from high density fiberglass and enclosed by fire retardant fabric.  ASTEX is easy to install, is virtually maintenance free and may be hoovered or lightly sponged.  It can be used as lining for studio, office, auditoria where high acoustic absorption combined with level of aesthetically pleasing appearance is required.

Thickness: 25 and 50 mm
Standard Size: 2.5 x 1.2 m
Weight: 3.25 kg/m² and 5.00kg/m²
Panel Fire Class: BS476, Part 6 & 7 – Class 0

Spray-on acoustic lining is a glass fibre based spray-on thermal and acoustic insulation lining.  It comprises of pure white, inorganic, non-combustible glass fibres that contains at least 25% recycled raw material and a non-hazardous, water-based synthetic emulsion adhesive.  This is a general-purpose acoustic lining designed to meet a variety of thermal and acoustic needs in different areas.  When sprayed into place, a monolithic, resilient and flexible blanket is formed that bonds easily to most sound, grease and oil-free substrates as concrete, clean steel, aluminium, wood, gypsum board, rigid fiberglass and plastic insulation materials.  It is a perfect choice when noise reduction within a building is required.  When use in conjunction with other acoustic materials, it offers excellent sound transmission control. 

The single-step, spray-applied process allows the most complex surface configurations to be covered easily and efficiently with no seams or voids.  The maximum thickness on overhead surface without mechanical support is 5” while on vertical surface is 7”.

Acoustic Door Seals can be mounted to door frame or door to effectively prevent sound from transmitting from one side of the door to another through aperture.  It is one of the essential elements for an acoustically insulated room.  Some of the models are made of silicon treated soft polypropylene with water repellent, anti-static or fire retarding treatment and sealing distance can be adjusted by turning the adjuster screw at the end of the fitting.  Various sizes are available to fit different types of door.
 

Acoustics panels compose of 65% of deal and 35% of cement.  Mineralization process makes deal more durable and stable but at the same time maintains its excellent mechanical properties.  The millions of tiny space in-between the deal offer outstanding acoustic properties.  Other features include thermal insulation, elasticity, light-weight, anti-shock, fire retardant, etc.  Its versatility makes it the perfect choice for wall, ceiling or flooring for theatre, school, office, studio, stadium, exhibition centre, etc.  A wide range of colour selection surely matches your aesthetics and functionality.  It complies with DIN 1101 which represents the highest and finest quality acoustics panel you can rely on.

Acoustic wood perforated panel was developed based on the need of sound absorption and sound reflection requirement.  The range of finishing materials from fabric, perforated wood veneer to perforated metal can work in harmony with variety of design and enhance the beauty and comfort of your room.  The system utilizes aluminium frame hook-on suspension concept and steel wall brackets for the panel, providing economical and quick assembly on site.  The air cavity space can be adjusted to suit lower sound frequency absorption and at the same time makes installation of power supply outlets, signage, cables, etc. an easy job.

There are two types of acoustic wall panel namely FD and FW.

Type FD panels are made from customized aluminium frames in any required shapes and sizes.  The panels are infill with 50 mm thick high density resin bonded rock wool slabs (density 80 to 100 kg/ m³).  The panels are faced with selected fabric which is acoustically transparent.

Standard Size: 1200 x 1500 mm, 1200 x 1000 mm, 1000 x 1500 mm
Sound Absorption Coefficient: 0.94 (500 Hz), 0.89 (1000 Hz), 0.98 (2000 Hz)

Type FW panels are made from 12 to 18 mm thick perforated MDF board in any required shapes and sizes.  The panels are infill with 50 mm thick high density resin bonded rock wool slabs (density 40 to 60 kg/ m³).  The panels are laminated with wood veneer with matt finishing.  The standard perforation shall be 10 mm diameter holes with different perforation pattern.  Black acoustic Soundtex Tissue is laminated at the back.

Standard Size: 1200 x 1500 mm, 1200 x 1000 mm, 1000 x 1500 mm
