Public-Facing – Extra security measures might be more of a concern if you’re placing your building in an area that is more public-facing than a garden.

We found at least 3 sheds that have options that you might find a better fit if this is a concern you have.

More Child Friendly – If you have children and you are looking for something that has that little extra in terms of durability then tougher glazing options might be a better option. Here we have at least 3 other options that will fill those needs.

1. Pressure Treated: Considered the most durable wood treatment, this is where the wood undergoes a process called tanalisation. This is where the timber is submerged in specialist wood preservatives (such as Tanalith E, this is actually the origin of the word ‘tanalisation’), this is a unique combination of copper and organic biocide ingredients (it is the copper that gives the finished wood the slightly green colour). The wood then goes into a high pressure vacuum tank (the Wood Protection Association has a good article/video on this) to draw out excess moisture and air and force in the preservatives.

This deep penetration of the exterior wood protects it from the elements and all forms of insect attack. Wood treated this way can last many years without being re-treated. The BS 8417 code of practice (this advises on the choice of timber species and the use and application of wood preservatives) says “ penetration to either 6 mm (15 years) or 12mm (for 30 years) has to be achieved in any exposed surface in sawn material.”

It is also worth noting that if cross cutting, notching or boring treated timber during or after installation, ALWAYS apply an end grain solvent-based (or oil-based) wood preservative treatment to the freshly exposed areas, this will maintain the integrity of the protection. NEVER put cut ends in the ground, even if end grain coated.
