Wood-based panel products for formwork linings

TRADA image

Wood products have traditionally been used as lining materials for formwork to concrete. Although timber planks were originally used as formwork linings, wood-based panel products are now more common in modern concrete construction.

This Wood Information Sheet (WIS) outlines a number of the key points and considerations to be made when using wood-based sheet materials for formwork linings, including the effect of the moisture in concrete on the timber's service class, the benefits of using plywood for in-situ formwork and the steps which must be taken to achieve a smooth surface to the concrete.

Cross-laminated timber: structural principlesnavigation-arrow

Cross-laminated timber (CLT) offers opportunities to use timber in taller structures with wider spans where designers would traditionally have used materials such as steel, concrete and masonry by default. As with any new structural material, it is essential that designers understand how to achieve CLT's potential while respecting its limitations.

Timber I-joists: applications and designnavigation-arrow

Timber I-joists are engineered structural components for use in walls, roofs and floors. They are widely used in the UK, particularly as floor joists. Their high strength-to-weight ratio, low weight, ease of installation and economy in use of materials make them popular, especially for long spans and multi-storey structures.
