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. Features such as security windows or even having no windows at all, and the ability to lock all opening doors are usually much more important when you have something that is more public-facing. We found at least 1 garden rooms 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. 

2. Polycarbonate: Is one of the toughest plastics available. The excellent toughness and thermal stability make Polycarbonate one of the most widely used thermoplastics. This durability makes this ideal for garden equipment and extremely durable plastic garden structure. Polycarbonate is also used for things such as riot shields, vandal proof glazing, safety helmets and headlamp lenses.

According to data from the British Plastics Fedaration the physical properties of Polycarbonate are that it is very good when exposed to high heat with a maximum continuous use temperature of 125 °C. This is coupled with the outstanding Notched Impact Strength data of 60 – 80 Kj/m². 

3. FSC Certified Timber: The Forest Stewardship Council (FSC) is an international organisation that is “dedicated to promoting responsible management of the world’s forests.” When you see the FSC certification it means the forest where this wood was sourced from is being managed in a way that preserves biological diversity, while ensuring it sustains economic viability. FSC-certified forests are managed to strict environmental, social and economic standards. FSC certified timber is comparable to Certified Timber
