Stock, sell and specify decking with confidence

August remains a key time for outdoor projects, making it the perfect opportunity to refresh your knowledge of timber decking products and help your customers choose the right solution.

As summer continues, many homeowners are still investing in their outdoor spaces, especially considering the ongoing heatwave. Whether they’re creating a new entertaining area, replacing ageing decking or completing landscaping projects before autumn arrives, demand for decking products remains strong throughout August.

For builders’ and timber merchants, that makes decking an important product category to understand. Having the right stock, backed by knowledgeable advice, helps customers select the most suitable materials while reducing the risk of specification issues later in the project.

Timber decking remains one of the most popular ways to transform an outdoor space. It offers an attractive, cost-effective solution for everything from garden seating areas and pathways to terraces, patios and commercial applications.

A well-designed and properly maintained timber deck can provide many years of service. Like any construction product, though, correct specification is essential. Different applications demand different products, and merchants should be familiar with factors such as timber treatments, Use Classes and structural requirements. For example, timber used within a decking substructure should be treated to Use Class 4, while some decking boards require reduced joist centres to provide adequate support under load.

Resources to support your customers

TDUK provides a wide range of practical guidance to help members build their knowledge of timber decking. The Merchant Guide to Selling Timber includes merchant-focused advice on decking board options, timber treatments and Use Classes.

The online Product Database also contains an introduction to timber decking, covering common board sizes, accessories, finishes and the relevant standards and certifications.

For those looking for more detailed technical guidance, the Timber Decking Handbook, produced with the Timber Decking & Cladding Association and the Wood Protection Association, is widely regarded as the industry’s definitive reference for timber decking design, specification and installation.
