Isolair Roof Systems... |
|
NBT Pavatex Pavaroof
system uses rigid, waterproof and breathable insulation
boards called Isolair. The boards are
tongue and grooved on all edges, allowing for rapid
and simple installation.
This modern method of
construction is time proven, with Pavatex starting
production of boards in 1932. The system is ideal
for new build, refurbishment and use on historic buildings.
Made from waste FSC wood,
Pavatex Isolair boards lock up more carbon than they
cost to produce and are completely non-toxic.
Pavaroof (Isolair and
Pavatherm Plus+) is available for both
pitched roofs (above 10* pitch) and
flat roofs. We supply all fittings
and accessories for the system. |

Pavaroof Advantages... |
|
|
Pavaroof
offers good insulation from cold. By over-cladding the
roof structure, cold bridging is minimised, further
improving insulation performance.
By using a water proof layer (either from Isolair or
Pavatherm Plus+ boards) no membranes are needed, simplifying
the build. |

 |
| Pavatex
woodfibre boards have a balance of insulation and thermal
mass. This additional mass means that the increased
heat and solar radiation is stored within the roof structure
by day, and released at night. This 'Decrement Delay'
can be up to 12 hours, meaning that rooms under Pavaroof
are on average 4 degrees cooler than other insulation
systems. |
|
|
 |
The
density and structure of the boards also offer significant
sound-proofing. When combined with other insulations,
a Pavaroof can offer significant reduction in sound
transmission.
This is especially true when compared to very lightweight
foam or multilayer systems, and can be very useful in
high density housing or urban environments. |

Pavatex
woodfibre boards are F90 fire rated, and independently
tested by Warrington Fire.
In a fire situation, a layer of ash rapidly forms, inhibiting
oxygen and deep burning, reducing the spread of flame.
No toxic gases are produced by Pavatex.
Compared to mineral fibre insulation, ignition of other
layers is delayed. |
|
|
 |
Like
a roof membrane, Pavatex products are breathable (or
'vapour open'). In conjunction with other vapour open
and hygroscopic insulations, Pavaroof can help control
the relative humidity of a room. This has significant
health benefits, as well as reducing mould and mildew.
This breath-ability also helps protect the roof structure
from decay, drawing away moisture from timbers and actively
transporting it outwards, where it evaporates. |

 |
Pavatex
boards (like any insulation) can significantly reduce
carbon emissions in buildings.
Extremely resistant to ageing, Pavatex are proven to
last the lifespan of a building, unlike many other products.
The boards can be stored outside prior to construction,
for 3 months, with no ill effects.
Any waste Pavatex products can be re-cycled, composted
or used thermally for energy generation. |
|
|
 |
The
boards are made from natural waste wood, from sustainable
sources. In combination with efficient manufacturing
this means that Pavatex boards are carbon negative -
locking up more carbon than they cost to produce.
Pavatex boards have no toxins in them, reducing our
exposure to many chemicals found in foam insulations. |
