We at Garden Products Online understand that shopping online is not always as easy as it could be and we always consider and appreciate all feedback, please find below some of the most frequently asked questions which will help you through the process alternatively please feel free to phone us for advice and guidance.

What is Tanalisation - A process where the timber is pressure treated (normally in green but some suppliers can offer brown) the timber is then guaranteed against rot and wood eating insects for ten years.

Why choose Tanalisation? - Having your building Tanalised from UK garden buildings is a worthwhile consideration, it will guarantee the timber against rot and wood eating insects for 10 years, the UK garden buildings range is dip treated in a red cedar colour and as with all timber products should be treated annually with a recognised brand of wood protection.

Why choose Bearers? - Bearers are pressure treated so guaranteed against rot and wood eating insects for 10 years they are used beneath the standard floor joists to raise the shed from the ground improving ventilation which in turn helps prevent damp at the most vulnerable part of the shed.

Why choose Toughened Glass? - generally unless specified the buildings will be delivered with 2mm horticultural glass, toughened glass is a safer option if in the event it is broken it breaks into many tiny pieces as opposed to shards which can be dangerous

Why choose 3/4 inch floor? - The upgrade to heavy duty floor is a must if the shed or workshop is going to be used for dragging machinery around it is a thicker floor than what is supplier as standard and naturally will last longer.

Why choose heavy duty felt? - The standard shed felt supplier is a good quality felt which will see an average shed through 5 years of normal use the heavy duty felt upgrade is a thicker grade mineral felt which should give a longer life for your roof covering.

What is FSC? - FSC is an independent, non-governmental, not-for-profit organization established to promote the responsible management of the worlds forests. FSC certification provides a credible link between responsible production and consumption of forest products, enabling consumers and businesses to make purchasing decisions that benefit people and the environment as well as providing ongoing business value.

Will I need planning permission - There are variations on planning for garden buildings, sheds, summerhouses and log cabins across the country, from our experience generally if there is going to be a problem it starts with the neighbours. as a rule of thumb the building should not be closer than 5m from the back of your house or taller than 2.5m within 1m from your boundary the building should not be bigger than 70 internal cubic metre these are what customers have informed us about and we advise if you have any doubt then please contact your local planning representative

Garden Building Directory of Terminology

The idea of this garden building index of keywords and terms is to explain some of the words and phrases used to describe our Sheds, Summerhouses and Log Cabins. I would like to think that purchasing a Shed or Garden Building from Garden Products whether using it for garden storage, a home office or a workshop is as easy as ordering a pair of shoes from next or weekly shop from Tesco once you have established the size and purpose then the glossary here will help you understand why we have various priced and quality garden buildings

Garden Products Online try to offer the best quality garden product from proven manufacturers and we have to rely on communication and feedback from our customers some of the more popular size garden buildings we have sold are the standard 6ft x 4ft Wooden Shed, 7ft x 5ft Potting Sheds, 8ft x 6ft Apex Sheds upto 24ft x12ft Workshops with a range of sizes in between especially when looking at the the Log Cabins or the Metal Sheds and intermediate sizes by request on the bespoke buildings or made to measure.

Aluminium Frame

The Aluminium frame Greenhouses are available in natural grey finish or green with many size and style options

Anchor Kit

For a shed or garden building the anchor kit are brackets that secure the building to the wall or floor, an anchor kit on play equipment would be a metal dowel rod with a plate at the bottom that allows the legs of the play system or swing frame to be secured to the ground.

Apex Roof Style

The Apex is the high point on a building where the roof shape from the Gable end suggests an A shape roof style.

Balustrades / Balustrading

Similar to what you see on a staircase they are usually found around a Log Cabin veranda or the veranda on a Summerhouse or Playhouse or a decking kit. They have many shapes and can be wooden or metal depending on product and manufacturer.

Barge Boards

See Fascia Boards fitted to the end of the roof

Barrel board

See Log Lap an alternative finish for Cladding on Garden Buildings


The Base would generally be the word used where you Log cabin Shed or Summerhouse is to be erected, we prefer to build Cabins and Sheds on flat level concrete or slabbed area sufficiently large enough to fit the cabin centrally and allowing 10-15cm extra on the external measure both width and depth. If your base is not level it can affect the settlement of the Cabin, Shed / Summerhouse even to the point of door and window fitting.

Base Rail

A Base rail is the continuous rail that forms the lowest part of your metal Shed and on some building is the part that anchors you shed to the base. A metal rail is mainly used in greenhouses or metal sheds sometimes it can be a timber base rail for a Shed or Log Cabin and even concrete base rail on a Greenhouse


See Veranda for Log Cabins and Summerhouse, garden furniture would be referring to the roof section on a hammock or top of a built up BBQ possibly even the reflective lid on a gas patio heater.

Cedar Frame

Cedar frame greenhouses a low maintenance wooden alternative to the more common aluminiumgreenhouse.

Cedar Shingles

Cedar shingles are available on some of our range Summerhouses they give a natural finish with wooden tile effect, as an upgrade why not ask us to quote for a Cedar Clad Garden Building.


When we talk of Cladding it is the wall material used to clad the frame of the building. Cladding ranges from 28mm to 120mm Log Tongue and Groove, Shiplap Cladding and Overlap.


Softwood and usually pressure treated to protect against rot and wood eating insects on some Garden Buildings decking is supplied as part of the veranda kit, with various thicknesses, widths and profiles all available in optional lengths.

Diagonal Bracing

Is used to add strength and rigidity on Shed and Garage doors. On the Supreme Sheds and Workshops also on some of the Heavy Duty Garden Buildings diagonal bracing is also used in the framework on the walls

Damp Proof Course - DPC

A thick plastic membrane used to prevent damp at the bottom of the cabin

Double Glazing

Double Glazed windows are standard on the larger Log Cabins 50mm Log + from Tuin. It is not difficult to replace the glass with double glazed panels on the smaller windows and doors if required.


The eaves height is the lowest point in the roof on a garden building where it meets the side walls on the majority of sheds and Log Cabins the roof may continue to extend past the wall.

Fascia Board

See Barge Boards fitted to the end of the roof at the front and back of the Shed or Log Cabin, Normally Straight but can be waved sculpted or engraved for decorative effect.

Feather edge

Feather edge refers to the shape of the timber board usually overlapped horizontally onto a fixed frame for she or summerhouse construction with the thicker end of the wedge shape at the bottom, sometimes known as vertical board when used in fencing

Felt Shingles

Felt shingles are an optional upgrade on most Garden Buildings and Summerhouses when used on Log Cabins they can really change the appearance as well as offering a thicker roof covering than the standard Shed Felt, effectively they are mineral felt sheets when overlapped and staggered from bottom to the top of the roof gives a quality tiled roof effect available in Sparkling Black, Green and Red with the Sparkling Black Shingle being our most chosen colour

Fixing pack

Most of the self assembly products we sell will require fixings from Brackets and screws to handles hinges and nails, generally these are obvious when you unpack the product and should contain instructions.

Floor Bearers

When we refer to the floor bearers it is the part of the Cabin floor kit usually pressure treated because they are in contact with the base, the floorboards are secured to floor bearers that run at 90 degrees to the floorboards

Floor joists

Timber joists can be used to create a Shed or Cabin base some people like to have them between the concrete base and the bottom of the shed or summerhouse to help improve ventilation which in turn helps prevent damp, depending on the size of the joist keep in mind it will increase the overall height of the Cabin or Garden Building.


See base referring to area where Shed, Summerhouse, Logcabin or Garden Building is to be erected.


FSC is an independent, non-governmental, not for profit organisation established to promote the responsible management of the worlds forests. FSC certification provides a credible link between responsible production and consumption of forest products, enabling consumers and businesses to make purchasing decisions that benefit people and the environment as well as providing ongoing business value.


We refer to the framing as the timber frame on which the outer cladding is fixed. Many manufacturers use different size thickness frames, which is a way of making cheaper buildings and although in most cases not detrimental potentially thinner framing can affect strength and rigidity. It is worth asking the question, remember buy cheap buy twice

Fully framed Door

A stronger more rigid door with a full frame in addition to ledge and braced


The gable is the end of the building, usually the front or back of the A not the sides.


Galvenising is the most common way of protecting metal, Galvanised products are far less susceptible to rust and ultimately require less future maintenance.


Glass supplied with Sheds and Summerhouse is standard horticultural glass but in many cases can be upgraded to toughened glass a must to consider when there is a chance they could get broken especially when children are around, even a double glazing upgrade on the Log Cabins an important feature when using Log Cabins as offices or practical exntensions to the home.


Depending on what you are using your Garden Building or Log Cabin for it is worth considering insulation, on most buildings there is a small floor cavity that can be insulated using a thermal foam board with reflective foil front and back and you can even insulate the roof.

Ledge and Brace

Ledge and brace is the term referred to as a particular style of Shed door which is fixed together usually with three horizontal ledges and diagonal braces, most of our Shed and Summerhouse doors are ledge and braced with full frames, also on our range of Timber Garages

Log Lap

Log Lap or Barrel board is a considered upgrade from standard tongue and groove or shiplap cladding not available from all Shed manufacturers but a nice finish for a Shed or Summerhouse if not purchasing a Log Cabin.

Mineral felt

See Shed Felt Mineral felt is often the term used to describe a roll of bituminous membrane covered in mineral granules to help protect against the elements, Standard colour is grey/green.

OSB board

OSB or Oriented strand board (or Sterling board) is an engineered wood with wood flakes bonded together, available in many different thicknesses and generally used by Shed manufacturers as a cheaper option for flooring or roofing as opposed to tongue and groove planks.

Overlap cladding

See Featheredge Sometime know as rustic with the planks being rough sawn generally not as long lasting as tongued and grooved but can service a requirement when budgets are restricted.

Pent Roof

Pent refers to a flat roof with a sloping pitch. A pent shed will have a high side sloping down to a lower mostly these pent roof Garden Buildings slope from front to back but they can be built anyway round.


Playhouses and some of the cheaper Sheds are delivered with a clear plastic as an alternative to glass.


A versatile plastic type material normally transparent although not completely clear similar view as corrugated cardboard with the top and bottom skin and ribbed between, used on greenhouses and conservatories available in varying thicknesses

Pressure treating

Pressure treated timber or tantalised is timber that is introduced to a Vacuum and when up to the optimum pressure the wood expands allowing chemical to penetrate deep into the wood. Pressure treatment guarantees the timber for at least 10 years against rot and wood eating insects.


The Ridge is the point on a building where the 2 roof sections meet and is generally the highest point of the building. Generally the ridge runs along the length of the building. This can be a vital element with regards to planning

Roof Pitch

The roof pitch is the angle of the slope of the roof.

Roof beams

Roof Joists or beams support the roof planks.

Roof Truss

On the larger cabins it is sometimes necessary to reinforce the roof and integral roof joists will be used, you notice this on the hip roof or pyramid style roofs where there is a central peak.

Shed Base

See base referring to area where Shed, or Garden Building is to be erected similar to Log Cabin Base.

Shed Felt

See Mineral Felt roof covering applied to the roof of Sheds and garden buildings including Dog Kennels, Hutches and other Outhouses.

Slide Bolts

These are generally used to secure the second opening door


Also known as Shiplap Tongued and grooved cladding. This is a more premium fully interlocking cladding system. Each board interlocks with the next creating a weatherproof seal deflecting the rain.


See Felt Shingles


An open or covered aperture built into the roof panel to enable extra light to the inside of the garden building, not standard on Sheds and Summerhouses or Log Cabins but can be added if required, some roof strengthening maybe be required.

Sterling Board

See OSB Board


See Pressure Treating

Tongued and Grooved

This refers to the panels that are secured to the frame work of the building. The boards are notched on the sides to lock into each other. This type of shed would be classed as a premium finish as opposed to an overlap shed


A porch area on the front of a Garden Building normally a decked area with a balustrade surround quite a nice feature on certain Summerhouses or Log Cabins a space to relax in the shade on a hot summers day.


Sometimes when lengths of timber dry it is possible they may twist generally this is not a major concern and most logs in your Log Cabin Kit can be manipulated to fit.

Woodgrain or Wood grain is a finish applied to metal garden buildings that is set into the metal and pressed in. A wood effect paint is then added to the steel sheets and the appearance is of a wood effect metal sheds

Wooden Floor Kit
A timber floor kit is usually constructed from fully pressure treated timbers for long maintenance free life. The floor boards are constructed from thick timber usually 19mm thick half lapped timber, and then mounted onto 50mm x 25mm sawn bearers.
