NEWTHERM^® P is a light weight non-combustible board specially designed to provide fire protection to wet risers, dry risers and fuel oil pipes of nominal sizes in the range 25mm to 250mm. Up to 240 minutes fire resistance can be achieved depending on the thickness of NEWTHERM^® P used, and the material type and dimensions of the pipe being protected. It is easy to work using normal woodworking tools. NEWTHERM^® P is fast and economical to install.

Effect of moisture

Excellent dimensional stability. Resistant to high humidity, moisture has no permanent effect on the performance of the board as it will not degrade the board or dissolve out any ingredients. It does not cause efflorescence. NEWTHERM^® P can be fixed at any time in the building programme even before external walls have been completed and the building made weatherproof.

Chemical

Unaffected by brine and chlorine, resistant to low concentrations of most acids and alkalis. Surface pH value 7-10.

Biological

Resistant to attack by insects or vermin. Rot resistant.

Thermal

Coefficient of linear expansion 4 x 10^-6 per°C.
Thermal conductivity 0.13 W/mK

NEWTHERM^® P is a low density calcium silicate board containing vermiculite and reinforced with selected fibres and fillers. It is formulated without any inorganic fibres. NEWTHERM^® P is off-white in colour with a sanded finish on both faces. It can be left undecorated or it can be easily painted. NEWTHERM^® P is rigid and robust but edges and corners should be protected where impact damage may occur.

Compatibility

Compatible with all common building materials; non-caustic and will not promote corrosion; will not affect bituminous compounds; when in contact with unanodised aluminium the latter should be protected.

Standard

Tested to British Standard 476: Part 20:1987 and non-combustible to BS 476: PART 4: 1970. Also tested to Singapore standard requirements FSB/PSB/001 dated 8th November 2000.
