Durability
Pipe Insulation is rot proof, does not sustain vermin and will
not encourage the growth of fungi, mould or bacteria. Pipe
Insulation is odourless and non-hygroscopic.
Thermal performance
Pipe Insulation has one of the lowest thermal conductivities of
any mineral wool pipe section and complies with the requirements of
the Building Regulations for pipe insulation. The thermal
conductivity varies with temperature in accordance with the table
to the right.

Acoustic performance
Where there is a need to reduce radiated noise levels from
pipework, Pipe Insulation provides effective control. The actual
performance varies with insulation thickness and surface
finish.
As an example, 50mm thickness of Pipe Insulation under 20 swg
mild steel gives an average reduction of over 28 dB. Particular
care is required to seal joints and avoid bridging to achieve the
best results.
Chloride content
Pipe Insulation contains inherently low levels of chlorides and
high levels of stress corrosion inhibitors in the form of sodium
ions and silicate ions.
Chlorides are common to most environments and can be deposited
on the surface of the insulation from the air or even from
operatives' hands. In the presence of water the chlorides can
migrate through the insulation and be concentrated on the insulated
surface thus increasing the risk of stress corrosion cracking of
austenitic stainless steels.
The water resistance of Pipe Insulation helps prevent this
migration whilst its natural inhibitors afford additional
protection.
Vapour and condensation
Pipe Insulation will help to prevent condensation and protect
pipework from freezing when applied in thicknesses as recommended
in BS 5422.
Environmental
Pipe Insulation is free from CFCs, HCFCs and any other material
with ozone depletion potential in its manufacture and content and
represent no known threat to the environment.
Pipe Insulation’s
manufacture has a low impact on the environment and is classified
as Zero ODP and Zero GWP.
Handling and Storage
Pipe Insulation is easy to handle and install, being lightweight
and easily cut to size.
Pipe Insulation is supplied in boxes which are designed for
short term protection only. For longer term protection on site, the
product should either be stored indoors, or under cover and off the
ground. Installation instructions are on every pack.
Pipe Insulation should not be left permanently exposed to the
elements.
