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.

PEFC CERTIFIED TIMBER: By choosing this product, you are supporting responsible management of the world's forests. This product is PEFC certified. Our PEFC licence number is PEFC/16-37-2190. Our PEFC chain of custody certificate code is INT-PEFC-COC-1119. To verify our PEFC membership visit the PEFC Member Search and search for Summer Garden (full name "Summer Garden and Leisure Buildings Ltd"). Please note if you want a genuine PEFC certified product it must include a valid PEFC claim, which must include a valid licence number and/or certificate code from a genuine PEFC member. It must also be described as PEFC Certified or PEFC Pure. Claims that "we use PEFC timber" or "our suppliers are PEFC certified" are dishonest, because the PEFC certifies products and not suppliers. If the claim is invalid the timber is not PEFC certified.

ABOUT THE PEFC: PEFC, the Programme for the Endorsement of Forest Certification, is a leading global alliance of national forest certification systems dedicated to promoting sustainable forest management through independent third-party certification. Since 1999 the PEFC has certified over 280 million acres of forest in 56 countries. PEFC promotes the stewardship and use of forests in a way, and at a rate, that maintains their biodiversity, productivity, regeneration capacity, vitality and their potential to fulfil, now and in the future, relevant ecological, economic and social functions, at local, national, and global levels, and that does not cause damage to other ecosystems. PEFC certification ensures that forest-based products reaching the marketplace have been sourced from sustainably managed forests.

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.

ONE PIECE EPDM ROOF: A tough EPDM rubber membrane is made in one piece to the size of your roof with no joins. It is easily fitted within a few minutes at normal temperatures with no heat required. EPDM rubber is completely inert, UV stable and not affected by extreme temperatures. It never perishes and it will not rot, split, crack or degrade. EPDM rubber lasts for years with little or no maintenance. It has been widely used in flat roofing for over 40 years from Alaska to the Middle East. It is increasingly popular in the UK where it is widely used for re-roofing flat roof garages and extensions. Even in extreme weather conditions EPDM rubber remains flexible and it will stretch to absorb any movement as a timber roof expands and contracts with the seasons.

UNTEARABLE ROOF FELT: This untearable mineral coated bitumen roofing felt is more durable than standard roofing felt. Standard felt is paper backed or fibreglass backed, both of which are very easy to tear or puncture. This weakness makes standard felt vulnerable to wind damage. Although our untearable roofing felt looks and feels the same it includes a concealed plastic membrane which makes it far stronger. The most common cause of damage to a standard felt roof is a gust of wind getting under the felt and tearing it. Once the felt is torn it is quickly ruined. Standard felt can be torn very easily but our untearable felt cannot be torn by hand without a cutting edge. Even aggressive attempts to tear the felt by hand will only wrinkle the edges as the hidden membrane is stretched.

RECYCLED PLASTIC BASE KITS: Our durable eco-grid and eco-paving base kits are a practical and affordable alternative to slabs or concrete. Lightweight and easy to install within a few minutes, these recycled polypropylene pavers simply click together with no fixings needed. The interlocking design helps to spread weight and ensures greater rigidity. Weed membranes are not needed below a timber floor. The self draining design prolongs the life of a timber floor. Unlike paving or concrete our plastic bases are fully relocatable. The base is normally at least 2" or 50mm larger than your building. Where space permits the base is normally laid full size but if required in a tight location our plastic pavers can be cut. Fast delivery within 3-5 days ensures that you can start work quickly.

ECO-GRID BASE KITS: Eco-grids are recommended if the sub-base is soil, sand or pea shingle but not on hard surfaces such as concrete, because the underside is not flat. Integral pegs on the underside help to level the base grids more easily in soil or sand or shingle. Our eco-grid plastic bases can support up to 200 tonnes per square metre. We offer exactly the same eco-grids as driveways and carparks. Gravel or shingle infill is not required below a timber floor. Whatever you store in your building, our eco-grids will support the weight easily. Each eco-grid is 472mm x 472mm and 40mm thick with an immensely strong 60x60mm hexagonal cell structure. Extensive preparation is not normally required - just level the soil and lay the pavers directly on soil or on a thin layer of sand or pea shingle. Any exposed edges around the base can be left unfilled or filled with gravel or shingle.

ECO-PAVING BASE KITS: Eco-paving is recommended if the sub-base is a hard surface such as concrete or paving slabs, because the pavers feature a flat and level underside. Our eco-paving is less brittle than concrete paving slabs, with a strong supporting structure. The surface looks and feels similar to pressed concrete slabs, with a slightly textured finish. Each eco-paver is 385mm x 385mm and 40mm thick. The pavers are quickly and easily easily laid over an existing hard surface.

WPC COMPOSITE DECKING KITS: This superb quality WPC wood plastic composite decking closely resembles real wood, with the same look and feel. However, it is virtually maintenance free and it will never rot. At a glance it is difficult to tell the difference between this composite material and real timber decking with a stained finish. Furthermore, the similarities are not skin deep like a thin veneer. The realistic finish has a fibrous surface which looks similar to the grain of real wood. This synthetic composite is also heavier and stronger than real wood. The strength, durability and lack of maintenance make this superb decking a popular choice with pensioners and discerning commercial buyers such as care homes. Occasional cleaning with soapy water normally restores the original appearance. If any dirt or stains become ingrained after prolonged neglect even the most stubborn marks can be cleaned with a pressure washer.

Our WPC composite decking is a revolutionary material which provides all the benefits of real wood without the maintenance. It can be left outside uncovered all year round. Unlike real wood this synthetic wood is a weatherproof material with no knots, splinters, machining marks or other imperfections. It will never develop splits or shakes and no sap will ever ooze out of it. Our wood plastic composite is an equal mixture of real wood and recycled plastic. Even the wood is a mixture of sawdust and unusable offcuts, so it is the ultimate environmentally friendly alternative to wood. The colour pigments are mixed in before the powdered composite is moulded into shape, so the colour runs all the way through the finished product. The boards are completely impervious to water. The boards can be sawn, drilled and screwed, just like real wood. You can fix it with standard woodscrews. Being heavier and denser than real wood, screw fixings are actually stronger in composite boards.

SEMI OPAQUE WOOD STAIN TREATMENT - FACTORY FINISHED: This high quality preservative finish is professionally applied in the factory. A semi opaque paint treatment is applied to the outside of the wall logs and to the doors and windows. The cabin walls are treated in a choice of colours. The doors and windows are treated inside and out in a complimentary light colour. This treatment is impervious to water but not to water vapour, which allows the wood to breathe and offers superior protection plus greater durability. The appearance of colours and shades may vary between different screens or devices. As the name suggests, the semi-opaque preservative treatment includes a mixture of opaque pigments to provide a coloured finish combined with a translucency which allows the grain and other natural features of the wood to remain clearly visible.

MICROPOROUS PRESERVATIVE - DELIVERED TO YOUR DOOR: Our quality microporous preservatives are impervious to water but not to water vapour. This allows the wood to breathe. You can order up to 3 separate colours if required. At least two coats are normally required with a further coat at periodic intervals.

Our 3 star preservative is practical and affordable with a choice of 4 colours. It covers around 10 square metres per litre and normally lasts 1-2 years before a further coat is required.

Our 4 star preservative is a high quality preservative which covers around 9 square metres per litre and normally lasts 2-5 years before a further coat is required. It is available with a choice of 12 colours.

Our 5 star preservative is a deluxe high build preservative which can be used to achieve a stunning finish. Each extra coat increases the colour and sheen. It covers around 8 square metres per litre and normally lasts 2-5 years before a further coat is required. It is available with a choice of 12 colours.

Based on average coverage five litres of our 4 star preservative is enough for two coats on an 8'x10' shed or an 8'x8' log cabin. Ten litres is enough for three coats on a 10'x16' shed or a 12'x10' log cabin. Coverage varies according to the smoothness of the surface and the porosity of the timber. We recommend that you order more than you need to be sure that you have easily enough. All of these preservatives are safe for use with children and pets. These microporous preservatives are only available when you purchase a Summer garden building or if you purchased a Summer building in the past. Prices include free mainland delivery to England, Wales and southern Scotland. Colours are only as accurate as reproductive techniques allow.

WATERPROOF COLOUR SEAL - DELIVERED TO YOUR DOOR: This advanced water-based microprous timber treatment uses the latest high-tech nanotechnology to create a long-lasting waterproof wood coating that is environmentally friendly. It is suitable for use on all softwood and hardwood products and is especially recommended for use on pressure treated timber, including sheds, summerhouses, gazebos, fencing and garden furniture. This timber treatment will colour, protect and enhance your exterior wood. It contains a mould inhibitor to protect the coating and can be used on all outside and inside timber. It gives a traditional matt wood stain finish in a range of natural colours. It can easily be applied by sprayer, brush or roller. It is recommended that the second coat is applied as soon as the first coat is touch dry. We advise for ultimate performance the timber has a wood preservative pre-treatment. For the first treatment, two coats are recommended and will give a traditional wood stain finish that is long lasting. A further coat is recommended every 2-5 years. One litre covers approximately 10-12 square metres. Coverage varies according to the smoothness of the surface and the porosity of the timber. On average five litres covers a 12x8 shed with two coats and ten litres covers a 10x20 with three coats. It is recommended that 2 coats be applied. We recommend that you order more than you need to be sure that you have easily enough. The appearance of colours and shades may vary between different screens or devices. Prices include free mainland delivery to England, Wales and southern Scotland.

WATERPROOF CLEAR SEAL - DELIVERED TO YOUR DOOR: Our hardwearing clear seal is ideal as a clear varnish for bare timber or as a waterproof top coat for painted wood and pressure treated timber. It is also ideal as a waterproof floor varnish, especially the polyurethane clear seal. The smooth and shiny finished surface is waterproof and easy to clean. Available in a choice of acrylic or polyurethane, these colourless water based coatings are almost odourless and recommended for smooth planed timber only. One coat is normally required as a sealing top coat on painted or treated timber. A minimum of two coats are normally required on untreated wood. Up to three coats may be required for floors. An unsealed timber floor quickly shows muddy boot marks and other dirt. For best results a floor should be treated at the earliest opportunity while the timber is new and clean. On average five litres of our 5 star clear seal is enough for three coats on a 12'x12' floor, two coats on the walls of an 8'x8' log cabin or one coat on the walls of a 12'x16' log cabin. We recommend that you order more than you need to be sure that you have easily enough. The price includes free mainland delivery to England, Wales and southern Scotland.

NATURAL WOOD OIL - DELIVERED TO YOUR DOOR: Our traditional wood oil preservative is linseed oil based and provides a natural ecologically friendly alternative to modern alkyd based preservatives. Wood oil combines the waterproofing qualities of a paint finish with the high absorption rate of woodstain. The natural oiliness provides a highly water repellent surface which protects the wood from moisture. The oil also penetrates deep into the wood and emphasizes the grain. The high elasticity of wood oil allows it to expand and contract with the wood as climatic conditions vary. Three coats are recommended with a further coat after 1-3 years. One litre covers approximately 12 to 16 square metres. Coverage varies according to the smoothness and porosity of the timber so you should order more than you need. On average five litres covers a 10x8 log cabin with three coats and ten litres covers a 20x13 log cabin with 3 coats. Colours are only as accurate as reproductive techniques allow. Prices include free mainland delivery to England, Wales and southern Scotland.

BURGLAR ALARM: This simple and effective battery operated burglar alarm kit is easy to install in any wooden garden building. The main panel features a digital keypad and a powerful built-in siren. Two pre-wired door contacts are also included complete with a length of cable which plugs into the main panel. A 9 volt PP3 alkaline battery is required, which is not supplied with the kit. The alarm is easy to set using the digital keypad. A delay allows plenty of time to enter or leave the building after setting the alarm. Once the alarm has been armed it will be triggered by opening the door or tampering with the wiring. When the alarm is activated the siren emits a powerful and unpleasant sound to deter intruders.
