In some situations, there is a requirement for party/compartment floors to achieve a one-hour fire rating. If AMW100 is supported by 25mm chicken wire mesh stapled to joist sides, the insulation will then provide this one-hour fire rating.

Acoustic Performance AMW typically provides a reduction in reverberant noise levels of up to 10dB when fitted under roof constructions Sound Absorption coefficients.

The graph below shows typical sound reduction obtainable under test conditions

Equipment

Mastic gun or Click n Seal gun

Our Acoustic Sealant is a one-part Fire Retardant Water-based Acrylic Sealant. It exhibits good adhesion to a wide variety of common building substrates without the need for a primer. Paintable with emulsion paint three hours after application. Allow 12 hours before overpainting with gloss paints.

When subject to flame our sealant will intumesce (expand and char), thus blocking the passage of fire and smoke.

Application Instructions

Joint preparation

The joint surfaces must be clean, dry and free from all contamination. The surfaces should be degreased using a suitable cleaner.

Joint Backing

Where applicable, appropriate joint filler e.g. our AMW or closed cell polyethylene foam, should be used to provide the correct joint depth (see chart under Technical Data for fire integrity and insulation achieved).

Application

Our sealant is supplied in cartridges and can be applied into the joint using a Caulking Gun. All joint preparation, priming, and sealant application should be carried out in accordance with BS8000 Part 16, the British Standard for the sealing of joints in buildings using sealants.

Joint Size suitability

Joint width

Minimum 6mm
Maximum 20mm (single application)

Joint Depth

Minimum 10mm on porous substrates
Minimum 10mm on non-porous substrates
Maximum 20mm

Width :Depth ratio (within above min/max restrictions)

Contact Technical Services. In general, joints should be as narrow as possible to prevent passage of fire.

Storage Life

12 months in original unopened package stored in a cool, dry place out of direct sunlight.

Health & Safety for Acoustic sealant

Avoid prolonged contact with the skin. If sealant cones into contact the eyes, flush with copious volumes of cold water and obtain medical attention. For further information consult Product Safety Data Sheet.
