SCANDINAVIAN REDWOOD OR WHITEWOOD: The most widely used timber in the UK for years, Scandinavian Redwood and Whitewood grow in the well managed forests of Scandinavia and the coldest parts of Northern Europe. The cold climate ensures slow growth. The growth rings are much closer together than faster growing trees from warmer climates. As a result the timber is heavy and durable with a close grain pattern. The wood is seasoned and kiln dried to achieve the correct moisture content before it is machined. Redwood and Whitewood are so similar in appearance and performance that it is difficult to tell the difference. Both are classified as slightly durable and treatment is required for outside use. The forests of Scandinavia and Northern Europe have been responsibly managed on a sustainable basis for centuries so Scandinavian Redwood or Whitewood is an enviromentally friendly choice.

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.

FAST DELIVERY FROM STOCK: The revolutionary design of these summerhouses allows fast delivery from stock of standard summerhouses using the same modular wall panels, while at the same time allowing a wide range of door and window layouts to suit many different uses. Traditionally summerhouses have been individually made to order to suit your individual design but this process takes a month or more. Until now the only summerhouses which are available with fast delivery are made to one design only and often to a very basic specification. These summerhouses include a more flexible design and a number of quality features.

MULTIPLE DOOR AND WINDOW POSITIONS: The clever modular design includes many wall panels of the same width which are interchangeable. As a result the door and window design can be customised to suit your requirements. The door can be positioned almost anywhere in any wall to provide the best access from within your garden. The windows can also be sited to provide the most light. The door and window positions can be decided on site during installation - this does not need to be specified when ordering.

HEAVY DUTY FLOOR & ROOF - NO MAN MADE BOARDS: The roof features 12mm thick interlocking tongued and grooved boards with 2" thick framing. The floor boards are substantial 18mm thick boards. This is stronger and longer lasting than the flimsy man made boards which are normally included with other summerhouses at around these prices. Man made boards do not last as long in damp conditions. The man made boards commonly used in cheaper summerhouses include chipboard and OSB or oriented strand board. These are often described vaguely as a "sheet floor" or "solid sheet" or a "solid board floor".

PLANED SHIPLAP CLADDING: These summerhouses feature smooth planed fully interlocking tongued and grooved shiplap wall cladding. This design ensures that rainwater drains faster and the timber dries quicker, which ensures a longer life for your summerhouse. Our shiplap is fully tongued and grooved which is stronger than the half lap shiplap or rebated shiplap used by some others.

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.

LOW LEVEL GLAZING: Low level glazing provides a panoramic view from inside your garden room so you can appreciate your garden fully. With low level glazing you can enjoy a better view of the garden, especially at sites where the garden slopes away.

SIZES - DEPTH AND WIDTH: Sizes are sometimes rounded to the nearest nominal size for ease of reading but the correct external wall sizes are listed alongside the price. The first dimension listed is the depth and the second dimension is the width. The depth refers to the sloping wall. The sizes listed are the external wall sizes. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger. All sizes are approximate.
