With Spring steadily approaching, customers are gearing up to rejuvenating and revamping their garden, deciding how they can transform it into a stunning, useful, external space. Some might decide to build themselves an elaborate summerhouse, others may decide on a timber decking area, however, whichever you choose you will need to use Treated, Tanalised timber to aid you in the construction.

A question many customers ask us here at Davies Timber is “what is Tanalised treated timber, and why do I need to use it?”. Treated Tanalised timber is used primarily in external applications, but also for internal roof and floor joists. The preservative is forced deep into the timber protecting the wood from within. This treatment extends the life of the timber, and protects against rot, wood decay and insect attack, therefore we recommend using a treated Tanalised timber externally.

As well as being durable, the timber comes in different strength grades, sizes and lengths, so you will be able to source the right piece of timber for your project. If during your project your timber needs to be re-sized, you must re-seal the timber with a suitable product, as once the timber is cut the tanalising starts to break down. Other advantages of using Tanalised timber are, here at Davies Timber, our quality treated Tanlised timber comes regularised with the edges eased, making it ideal in applications such as children’s play areas. Other applications it can be used for are:
