PRESSURE TREATED TIMBER: Pressure treatment is a lifetime preservative treatment. The preservative is forced deep into the timber under pressure in a vacuum and penetrates below the surface. All other treatments apply a coat of stain to the surface of the timber only. With pressure impregnated timber, the chemicals are permanently bonded to the cell structure of the wood at a molecular level. Tanalith E is a widely used water based version so pressure treated wood is often described as tanalised. Pressure treated wood is almost colourless except for a slight green tint caused by the copper content in the preservative. No further preservative treatment is ever needed. However, if you want a coloured finish you can paint over pressure treated or tanalised wood with normal wood preservative in any colour.

DECORATIVE FELT TILES: Mineral coated bitumen felt tiles are an attractive and durable roofing material which is far more hardwearing than standard roofing felt. Traditionally used for small buildings only in the UK, felt tiles are used much more in Scandinavia and North America where they are used widely in general housebuilding. The sophisticated design features a strip of almost dry bitumen adhesive. Over time each tile sticks to the tile below for improved waterproofing and windproofing. All fixings are covered by the next row of felt tiles, partly to ensure a neat appearance with concealed fixings but mainly to protect the fixing holes from any possible moisture. Mineral felt tiles are made using asphalt with a bitumen binder and an external covering of durable and attractive natural stone chips. Mineral felt tiles are often described as felt shingles because the design resembles traditional cedar shingles.

TOUGHENED SAFETY GLASS: Toughened safety glass is around 6 times stronger than normal glass so it is less likely to break. When it does break, toughened glass breaks into harmless small pieces. This makes toughened glass the best option for all the family including children, pets and the elderly.

OCTAGONAL BUILDING SIZES: For ease of reference these octagonal summerhouses are measured as a rectangle. The first dimension listed is the overall width from side to side and the second dimension is the depth from front to back. The external wall sizes are listed alongside the price. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger.
