Black Armaflex Pipe Insulation lagging Wrapping Tape 50mm x 3mm x 15m Class 0

CLASS O ARMAFLEX -
The professional insulation that prevents condensation and energy losses

Armaflex is a highly flexible elastomeric material which is quick and easy to install and available in both tube and sheet form. It has a closed cell structure which has a built in vapour barrier with a high resistance to water vapour transmission enabling the insulation material to maintain a higher level of energy conservation efficiency.
In tube form, installation of Class O Armaflex can be carried out as the job progresses by sleeving onto pipes or if insulating an existing installation pre slit material is available, which can be snapped on and sealed using an Armaflex adhesive. Class O Armaflex tube is available in 2 metre lengths and as continuous coil in a box, meaning less cutting, less waste. In sheet form, Class O Armaflex is the ideal choice for insulating tanks, ductwork, large pipes or irregular shapes.
Flat sheets are 2 metres long x 0.5 metre wide or alternatively 1metre wide continuous rolls are available for economic material usage. All sheet material is available with or without a self adhesive backing.
Class O Armaflex has an excellent fire safety performance achieving BS476 part 6 1989 for low fire propagation, producing minimal contribution to the overall heat release, and BS476 part 7 1987 for zero surface spread of flame. Class O Armafix pipe supports are recommended for use where thermal bridging may occur. This is particularly important on refrigeration and chilled water pipes where there is a possibility of condensation taking place, particularly between the pipe and it's fixing. In heating installations the use of pipe supports will generally improve energy conservation.

The Competitive Advantage of Specifying Class O Armaflex

Lightweight and flexible means easy and speedy installation with low maintenance, resulting in time and cost savings 
Wide range of tube and sheet sizes available 
The low thermal conductivity, 0.034 W/(m.k) at 0C, and good acoustic performance provide double benefits with one insulation system 
Closed cell structure provides a built in vapour barrier 
A high, 7000, resistance to water vapour transmission and water ingress, gives long term insulation efficiency for condensation control 
Low Toxicity Index for added safety assurance
Class O fire category means low fire propagation index, producing minimal contribution to overall heat release, and a zero surface spread of flame for a high degree of fire protection and safety
Excellent resistance to the effects of ozone, oil, chemicals, extreme weather conditions and wear & tear 
Dust, fibre and CFC free with an Ozone Depletion Potential of zero  
BS EN ISO 9002 and 14001 approval confirms continuity of quality
