How robust is it?
It is the most robust system available on the market. One of the great attributes of the system is that once installed it can be used for storage and walked on without a problem. Sharp objects could penetrate the membrane but this is easily repaired.
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 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 are 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.
What substrates are required?
Neuchatel can be laid on most types of rigid sub-structure such as concrete, 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. Therefore a 20 mm job weighs 48 kg.
Can You Collect Drinking Water from Neuchatel?
Neuchatel is non-toxic and is suitable for use in contact with potable water.
