General Physical Data
|Flammability:||BS 476 Part 4 (1970) Non-combustible|
|Building Regulations:||Class O|
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

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.

The joint surfaces must be clean, dry and free from all contamination. The surfaces should be degreased using a suitable cleaner.
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).
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
Maximum 20mm (single application)
Minimum 10mm on porous substrates
Minimum 10mm on non-porous substrates
Contact Technical Services. In general, joints should be as narrow as possible to prevent passage of fire.
12 months in original unopened package stored in a cool, dry place out of direct sunlight.
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.
*Test incorporates seals and backing material on both faces of the construction.
Packaging: Polyethylene nozzles are included with each tube. Important: The information in this leaflet is given in good faith and based on results gained from experience and tests. However, all recommendations or suggestions are made without guarantee since the conditions of use are beyond our control. Goods are supplied subject to the Company’s terms and conditions of sales.
1. Composition/Information on ingredients
Plasterboard and cove comprise in general of a core of calcium sulphate dihydrate encased in paper liners. Minor additives include starch, foaming agents and dispersants. Moisture resistant boards and core board contain a silicone additive.
Fire resistant boards and core board include small quantities of glass fibre and vermiculite.
Foil-Backed boards are backed with a metalised polyester film.
2. Hazards Identification
Cutting and sanding of plasterboard or cove may generate excessive dust.
Gypsum dust may irritate eyes or sensitive skin, it may irritate the respiratory system.
It is better for the operator to wear non-restrictive clothing, especially avoiding constrictions at neck and wrist etc. It is recommended that work clothing should be washed and company separately from other family clothing.
3. First Aid Measures
Inhalation: Remove the person to fresh air.
Skin contact: Rinse skin with running water, then wash with water and soap.
Eye contact: Irrigate with plenty of water and obtain medical advice.
Ingestion: Wash mouth out and drink plenty of water.
Please note: should any symptoms persist obtain medical assistance.
4. Fire-fighting Measures
Plasterboard and cove have a limited combustibility.
5. Accidental release measures
The formation of dust should be controlled and suppressed, collect released dust and put into bags.
Prevent these products from contaminating drains and watercourses.
(refer to section 8, Exposure/Protection and section 13.
6. Handling and Storage
Plasterboards are supplied shrink wrapped on timber bearers. Packs should be lifted with a fork lift truck, the forks being set so there is an even weight distribution and no deformation of the pack. Ensure
handling equipment is of adequate capacity and that the personnel are advised of handling procedures and safety clothing. Care should be taken at all times to avoid strain to the handlers. Boards should not be lifted at the short edges or carried horizontally. Carry the boards on the edge, two persons per board by supporting one long edge and gripping upper edge to avoid breaking due to flexing.
Plasterboards must be stored flat in a clean dry environment on a flat surface. If timber bearers are used to
store boards on site, they should be a minimum 40mm wide and placed at a maximum 450mm centres.
Note: If handling manually, consider risks as required by manual handling operations regulations 1992.
Plasterboard are not designed to support body weight; fixers must work from an independent support
7. Exposure controls/personal protection
Occupational exposure limits
|Substance||Total inhalable||Total respirable|
Note: 8 hour TWA reference period
The man made mineral fibres (MMMF) used in our Acoustic Plasterboard.
Respiratory: The area of work requires appropriate ventilation and dust formation should be minimised and controlled. If dust formation can not be controlled wear a half face mask to EN 149 Class FFP1S.
Hand: Protective gloves can be worn, a barrier of cream can be applied to the hands to reduce the effect of hand contact.
Eye: If the formation of dust is likely to occur, safety goggles to BS EN 166 2A5 are recommended.
Skin: To avoid skin contact wear overalls and footwear.
8. Physical and chemical properties
Appearance: Plasterboard is a sold flat sheet in a paper envelope.
Colour: Varies depending on type.
pH: 7 (Neutral)
(Refer to section 1 Composition/Information on ingredients)
9. Stability and reactivity
Stable and unreactive.
10. Toxicological information
Inhalation: Dust can cause short term irritation to the respiratory system, no known long term effects.
Skin contact: Prolonged or repeated contact may cause dry skin leading to irritation.
Eye contact: Short term irritation can be experienced due to dust formation.
Ingestion: Wash mouth out and drink plenty of water.
11. Ecological information
12. Disposal Considerations
