LOG CABINS - THE BENEFITS: Log cabins are popular for many reasons, especially as a comfortable garden room to sit and relax in but also as a workshop or heavy duty storage shed. On the outside cabins have a chunky look and feel. On the inside, with no internal framework, the clean lines look smarter than the inside of a traditional shed or summerhouse. In addition, the wall logs are thicker than the shiplap cladding used in traditional sheds and summerhouses, which provides better insulation. If you want the option of winter use we recommend floor and roof insulation, which is difficult to fit retrospectively so it needs to be fitted with the cabin. We offer low price insulation packs complete with fixings and instructions. Where available, double glazing also improves the insulation especially if the cabin has a large glazed area. Another significant benefit of log cabins is that you get more wood for your money when compared with a traditional shed or summerhouse or garden office. With no prefabricated wall panels a log cabin requires less production time.

NORDIC SPRUCE: This building is manufactured from 100% Nordic Spruce, the best quality timber used in log cabin construction. Nordic Spruce is grown primarily in the well managed forests of Scandinavia, Siberia and the coldest parts of Northern Europe. The cold climate ensures slow growth. The growth rings are much closer together than trees grown in warmer climates. As a result the timber is heavy and durable with a dense grain pattern. These forests are expertly managed on a sustainable basis so Nordic Spruce is an enviromentally friendly choice.

NATURAL WOOD: First, high grade timber is dried in kilns until it reaches the optimum moisture content, then it is planed smooth and machined into tongued and grooved logs and boards. Next the logs are precisely machined at the ends to ensure a precise fit. Finally, each cabin is carefully packed and wrapped. When you unwrap it the wood is untreated. We recommend treating it only after the cabin has been successfully installed and ideally within a week or two. Treating the logs before fitting may cause the wood to swell up and the logs may not fit together correctly. If you are fitting your cabin in a restricted space where future access will be difficult you can stain the logs during installation by reaching down a few logs at a time as you fit them.

FULLY INTERLOCKING LOG CORNERS: These traditionally made log cabins feature interlocking corner logs. Each wall log is precisely machined and notched out to ensure a strong and weatherproof joint. The first log is laid at the bottom and the rest slot into each other, working upwards one log at a time. No screws or nails are required which makes installation easier and also allows for timber movement. The finished corner assembly is not only immensely strong but also weatherproof and draughtproof. If possible cabins with interlocking logs should be treated after assembly. Treating the logs on site before fitting requires considerable care. If swollen the precision milled joints may not slot together.

WEATHERPROOF DOUBLE GROOVED LOGS: Thinner wall logs feature a single tongue and groove but thicker logs feature a double tongue and groove. The double tongue and groove provides a stronger and more weatherproof joint. Thicker logs also provide improved insulation.

CHAMFERRED TOP WALL LOGS: This high specification building features a subtle quality feature. The top log in each side wall is chamferred to the same angle as the roof slope. This little detail provides much improved insulation and draughtproofing. It also provides a much neater internal appearance and the roof boards are easier to fix. This simple design feature eliminates an obvious cold spot. The benefits of this feature are magnified if roof insulation is specified.

HEAVY DUTY TONGUED AND GROOVED FLOOR: This cabin includes a heavy duty timber floor with tongued and grooved floor boards and substantial floor joists. Skirting boards are also included to ensure a neat internal finish. The floor joists and tongued and grooved boards are supplied loose for fast assembly on site. Unlike many log cabin floor kits, all timber is cut to size which saves time during installation. It also ensures that there are no visible joins in the finished floor. The floor is assembled quickly with no visible joints. With some cheaper cabins the boards must be cut to fit on site. This takes much longer and many of the joins are visible afterwards.

PRESSURE TREATED FLOOR JOISTS: The floor joists are the only timber in direct contact with the ground and they are pressure treated for durability. The joists are laid down on the base first and then the first wall logs are placed on top of the joists. The floor boards are often fitted at the end, after the cabin has been completed. This design ensures that the wall logs and the floor boards are not in contact with the ground. It also allows for ventilation and drainage below the floor and the walls. Pressure treatment is a lifetime preservative treatment. The preservative is forced 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 fixed in the wood. Tanalith E is the most popular preservative used so pressure treated wood is often described as tanalised.

METAL STORM BARS: Storm bars are an important quality feature. One obvious benefit is that storm bars help to protect your log cabin from wind damage. In addition, by clamping the logs together storm bars make the joints more weatherproof and reduce any bowing or twisting of the logs. The storm bars are fitted at each corner to hold the individual logs together tight. This counters the impact of strong winds. This feature is especially useful if the cabin has a large roof overhang which is exposed to the wind. Many log cabins do not include any storm bars at all and those that do normally include timber storm battens. These metal storm bars are much stronger and neater, being almost completely invisible. Substantial full height threaded steel rods are passed through every log at each corner and bolted at the top and bottom. The bottom of the rods are easily accessible after installation so they can be tightened or loosened as required to allow for any timber movement. It is only possible to fit threaded rods in cabins with thicker logs, because drilling holes in thinner logs reduces their structural integrity.

JOINERY DOORS & WINDOWS: These log cabins feature joinery made door leaves and window sashes with morticed and tenoned joints throughout. This traditional jointing process is commonly used in the housebuilding industry when timber windows and doors are specified. A rebate or mortice is cut out in one piece of wood which precisely matches a tongue or tenon cut in the other piece of wood. Morticed and tenoned joints are the strongest type of joint used in the construction of wooden windows and doors. High quality handles, locks and hinges are also included.

HIGH PERFORMANCE DOORS AND WINDOWS WITH WEATHERSTRIPS: Our high performance premium window and door frames feature weatherstrips to reduce draughts. Weatherstrips are rubber gaskets which are fitted to the door and window frames. The weatherstrips are fitted in the rebates between the fixed outer frames and the hinged parts i.e. the window sashes and door leaves. As the doors and windows are closed the weatherstrips are compressed to form a seal. Heat loss is significantly lower through windows and doors which are fitted with weatherstrips.

DOUBLE GLAZING: Our double glazed doors and windows ensure that your log cabin is warmer and cheaper to heat. We recommend double glazing if you want to use your cabin all year round. Double glazing also provides additional sound insulation. If you expect to use your cabin frequently and often for prolonged periods we also recommend floor and roof insulation. Insulation ensures a more comfortable environment on the hottest days in the summer and the coldest days in winter.

ALUMINIUM WINDOW CILLS: Our high performance premium windows feature profiled aluminium external cills for durability. The modern profile design also allows rainwater to drain away from within the window which prolongs the life of the window and the double glazed units.

METAL DOOR THRESHOLD: A weatherproof metal threshold is included to provide sustained access for heavy items such as ride on mowers and motorbikes. Without a metal threshold the wooden frame is vulnerable to wear and the elements. Over time a metal threshold will extend the effective lifespan of the door.

LAMINATED DOORS AND WINDOWS: Laminated wood is an engineered structural timber. Precisely machined small sections of wood are glued together under high pressure with strong waterproof adhesive. After extensive machining the finished piece of timber is barely distinguishable from real wood - it is real wood, but it is stronger and less likely to warp or twist. Doors and windows made with laminated timber are less prone to distortion. This is because one piece of wood can move erratically while many pieces of wood counteract each other. It is rare to find laminated doors and windows specified in a log cabin due to the high production cost. This is an important quality feature because in a log cabin the doors and windows are a vital component which is particularly exposed to the elements. Laminated timber is also kind to the environment because it uses offcuts and creates less waste.

BUILDING REGULATIONS: This log cabin features an internal floor area of more than 30 square metres and less than 50 square metres. It therefore requires limited structural approval under Building Regulations in England and Wales. It is exempt from the insulation requirements if it is built as an additional room in the garden of a domestic dwelling. The structure of this log cabin is strong enough to obtain approval without modification. The specifications of our roofing options also comply with Building Regulations. The prices for mineral felt tiles include underfelt. The prices for granular steel tiles and cedar shingles include underfelt and battens. The prices for roof insulation include a layer of decking on top.

SIZES - DEPTH AND WIDTH: The sizes are listed alongside the price. The first dimension listed is the width and the second dimension is the depth. The width refers to the angled gable walls at the front and rear including the door wall. The depth refers to the side walls. 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.
