Non Face Brick

What you need to know about Clay Plaster Brick Walling

Clay brick cuts down on noise
Heavy weight clay brick walling is an ideal means of insulating buildings against noise. Even a single wall of clay brick is able to reduce noise dramatically. A double wall is capable of reducing noise by half as much again to produce a relaxed and peaceful environment, relatively free from outside distractions.

Clay brick keeps interiors comfortable
Heavyweight clay brick walls have an inbuilt to keep buildings cool in summer and warm in winter. During the day, clay brick slowly absorbs and stores heat thus helping to keep buildings cool. During the night, the stored heat is slowly released and this assists in maintaining the inside temperature at a consistent level thereby minimizing the need for heating and cooling and associated energy costs.

Clay brick is fire resistant Clay brick is fired at high temperatures during manufacture and therefore, is incombustible - it cannot burn anymore. So a brick wall does not help to spread the flames. In fact, it is highly resistant to collapse in the event of fire.

Strength and stability
Walls built with quality clay face bricks which are properly constructed will produce strong, stable and durable buildings.

Thermal insulation
Clay bricks built in the form of solid or cavity walls offer excellent protection against heat and cold.

Clay bricks are impervious
Clay brickwork correctly laid is devoid of cavities and crevices and therefore impervious to vermin infestation.

Classification

Non face bricks, known variously as plaster, common or stock bricks, are supplied in two categories:

NFP - Non Facing Plastered
Clay bricks that are suitable for general building work which must be plastered or rendered.

NFX - Non Facing Extra
Bricks suitable for use, plastered or unplastered for general building work below damp proof course or under damp conditions or below ground level where durability rather than aesthetics is the criteria for selection.
