Faqs
How much does it cost?
A 20mm (2x10mm) Neuchatel roofing system generally costs only slightly more
than a two layer bituminous membrane system.
How long does it take to lay?
Despite being labour intensive, installing Neuchatel is surprisingly quick work.
A skilled spreading team can complete around 200sqm of open deck area every day.
You can walk on your Neuchatel roof or car park as soon as the Neuchatel has
cooled enough to turn into solidified form, which is generally around an hour.
It is best to leave Neuchatel system of average thickness about three hours to
properly cure.
Does it smell?
The mastic asphalt that Neuchatel sources from Permanite is of a very high
quality. It melts very cleanly and does not give off much odor at all.
What about the fumes of the molten mastic asphalt, is it
dangerous?
What looks like fumes is in fact steam rising, environmental health officers
would not allow us to install a dangerous product. We strictly adhere to health
and safety regulations and international codes of best practice.

pre-cast concrete deck units, timber boarding, metal decking and other
proprietary decking units.
Thermal insulation materials can easily be laid as part of a mastic asphalt
specification to give any required U-value.
What surface finishes are available?
A sand finish can be provided to produce a surface suitable for traffic.
Alternatively a coating system must be applied for solar reflectivity and to
provide a decorative finish.
How much does it weigh?
The weight of Neuchatel varies because of differing compositions. The precise
coverage obtained will depend upon a number of factors such as the nature of
the added coarse aggregate. For the purpose of calculating loading use 2.4
kg./m2 per mm. of thickness for the laid material.
