All the timber used in our units is FSC Certified, Pressure Treated, Swedish Redwood Timber treated with TANILITH-E. However, to get the best out of it, you will need to continue it 'scare over the years.

The Pressure Treated preservative is designed to protect the timber against rot and insect attack to give the softwood an extended and low maintenance service life. The treatment is not intended to perform as a waterproofing agent and so water may permeate through the product.

To help avoid this, a well maintained water repellent coating can be applied to the timber. We recommend Restol for this, following the manufaturers instructions. It is a clear, linseed wood oil treatment with protective UV agents especially for pressure treated timber.

Alternatively you can use a high-quality wood stain or paint to help seal the timber and create a water-repellent coating. A good micro-porous wood stain will allow any internal moisture to evaporate out of the timber.
