NBT Clay Board

NBT Clay board is a composite board consisting of clay, reed and hessian. The reeds from managed reed beds run along and across the board length and the board is faced on both sides with hessian. This acts as reinforcement and a plaster key. The constituents are mixed wet and formed into panels then cut to length and width.

Consistency of the product is monitored by quality tests carried out by the manufacturer:

• Tests of physical properties to ensure suitability of clay.
• Visual inspection of reeds and hessian before manufacture.
• Visual checks for damage & flaws before shipping.

Clay board is suitable for internal use in drywall construction on walls and ceilings. It is a practical alternative to using gypsum plasterboard and lath-and-plaster and is compatible with clay or lime -based plasters.

The application of clay products in general influences the internal building environment by regulating temperature, absorbing moisture and odours and insulating against sound transfer.
