General Design Criteria


Exposed and Windy Conditions
The data presented in this catalogue is a guide only. For normal wind loading conditions or for structures in high wind areas, an Architect or Engineer should be consulted for advice on specific fixing
recommendations. It is possible for water to be drawn upwards where walls or gables are exposed to a high degree of wind and rain. Walls exposed in this manner should be fully backed with a durable waterproofing membrane in sheet form which should be fixed between the Building Planks and the vertical studs.

Supporting Structure
To ensure a high standard of finish, it is essential that the supporting structure is accurate and straight.
Warped, twisted or poor quality timber will reflect in the final appearance of the Building Planks. Use only well seasoned graded structural timber.

Supporting timber structure used on masonry walls should not be less than 38 mm x 38 mm.

The distance between vertical supporting timber or metal studs should not exceed 600 mm. Nutec Building Planks should be lapped by a minimum of 25 mm.

When using Nutec Building Planks as cladding for timber framed housing or for cladding of masonry walls, the cavity formed should be ventilated.

In this type of construction various types of foil are usually used as a moisture barrier and as an insulator.

Ventilating the cavity will permit the evaporation of any condensate which may collect on the insulation material.
