NBT Launches New Coloured Earth
With a range of ecologically sound self-coloured clay plasters NBT has introduced two separate ranges of self-coloured, high performance, clay-based top-coat plasters.
The boards are manufactured from waste pine wood, are fully interlocking, airtight, breathable and completely eliminate the requirement for membranes or ventilation of the roof space.
The system not only provides very effective overheating control in summer but also high acoustic and thermal insulation (typical U value of 0.19 W/m2K) - and it also eliminates the risk of interstitial condensation or rot.
The construction has low embodied energy, low CO2 emissions (including during manufacture) and, as the products can be composted, no special provisions have to be taken on disposal.
NR1 is fast to build and offers robust detailing - with few skilled operations needed.
It offers excellent value for money and all of the materials are non-toxic, non-irritant and easy to handle.
The system is particularly suitable in situations where the loft is intended to be used as living space.
