Take the stress and expense out of extending your living space with our Avon Insulated Log Cabin. The W3.0m x D3.0m Avon Insulated Log Cabin consists of pre-manufactured logs which have polyisocyanurate insulation sandwiched between the timber. These help to keep your Log Cabin as warm as a cabin with 140mm thick walls, meaning the party doesn’t have to stop when the nighttime chill sets in. Just close the French double doors and double glazed windows and enjoy your toasty cabin. Our four-point locking system ensures your fully stocked bar or cinema-sized screen are safe when you lock up. We pressure treat the floor bearers to protect them against rot and insect infestation, something many of our competitors don’t, but the rest of your cabin is delivered untreated. This is to allow you to treat it in a colour that suits your own style.

Get your money’s worth and make full use of your Log Cabin all year round! With our revolutionary new combination of wall, floor and roof insulation, it’s easy to maintain your cabin at a comfortable temperature for use whenever you need it! Our insulated Warmalog® cabin has a Triple Tongue and Groove 62mm sandwich of timber and polyisocyanurate insulation. As a result, it has a specification better than any comparable solid wall log competitor, and is keenly priced for all your needs. Another exciting and innovative product from Dunster House!
You will need to prepare a solid base that is square and level to allow you to build this insulated log cabin successfully on your property. You can use concrete or our RapidGrid Foundation system. We recommend a base of 3.0m x 3.2m for the Avon Warmalog®. The only extras needed are a superior quality light coloured 'Barn' paint for the exterior, as well as a clear silicone sealer for the joints. These are available from your local decorator supplies.
Of course, it's not just the walls. Warmalog® Cabins are insulated in all directions. The floor has a 50mm thick insulated structure, the roof is 60mm (also insulated) and the windows are made of 4mm toughened glass in a 24mm-thick Double Glazed unit. Thanks to these and other heat-conscious design details, these Warmalog® cabins achieve a U value of 0.69. This means that you can feel confident your cabin will remain cool in the warm months and warm in the cool months.
This quality garden timber building is suitable for a variety of purposes, such as a home office, a music room, gym or even a bar. Whether it's extra space to work in, or for working out, or for any other special purpose, it's good to know that the seasons will not limit the use of your great new garden building! Strong and sturdy, the Warmalog® has secure Espagnolette Multi-Point locking systems on its large windows and wide-opening French Doors. The roof is strengthened by larger Purlins, and pressure treated floor bearers are included.
The Warmalog® is easy for home owners to assemble. Log Cabins will never be the same again!
Fully Insulated
We never compromise on quality which is why the insulation that we use in our Warmalog cabins is of the highest specification. It’s called polyisocyanurate and it is one of the best insulators available, it’s so effective that even NASA has used it to insulate the external fuel tanks of their space shuttles!
Polyisocyanurate is a great material because not only is it lightweight and versatile, its high thermal conductivity makes it sought after. Competitors insulation might be cheaper, but they may use Rockwool or polystyrene, which are inferior materials. Polyisocyanurate is said to be 50% more efficient than Polystyrene and up to 100% more efficient that Rockwool.
It’s not just the walls that are insulated in a Warmalog cabin! We also provide the same kind of insulation for the roof (60mm thick) and for the floor (50mm thick). As well as this coverage, the Warmalog cabin comes with 24mm thick double glazing as standard.
All of this heat-retaining technology ensures that any Warmalog cabin can achieve a U-value of 0.69. The U-value assesses the rate of heat loss / gain through all the thicknesses of the combined elements that make up a building component such as a wall, floor or roof. Simply put the higher the U-Value the worse the product performs. Our Warmalogs U-Value of 0.69 is considered to be very low, meaning you’ll save a fortune on heating bills compared to Polystyrene or Rockwool insulated cabins!

Internally Beaded Windows
62mm Interlocking Logs
We only use full lengths of engineered precision cut and routed tongue and groove timber in our log cabins. These logs go through a process of being planed, leaving you with a smooth finish. We believe that using full lengths of planed timber gives you a more aesthetically pleasing and stronger product.
Other companies are happy to provide you with rough offcuts, glued and finger jointed together, creating a weakened cabin and off-putting appearance.

4mm Toughened Glass
The 4mm toughened glass that’s used to make up the double glazing in our windows and doors of our Warmalog cabins for increased security and resilience. It's much better than the 3mm ‘Shed-Spec’ horticultural glass which is commonly found in our competitors garden buildings. It is much more difficult to scratch or bend than the plastic alternatives, such as Styrene, Acrylic and Perspex, so it'll preserve the clear view of your garden.
The tempering process makes our toughened glass far stronger than the alternatives, and harder to break than normal glass. In addition, if it does happen to break, it will shatter into many small pieces, rather than scattering dangerous, razor-sharp shards. So confident on the superior quality we tested it against the other types of glass commonly found on the market and, of course, it came out on top!
24mm Double Glazing
This Warmalog cabin comes complete with 24mm sealed window units for increased insulation and noise-reduction. This is a single, ready-to-install unit comprising of two sheets of 4mm toughened glass with a 16mm aluminium spacer, which allows for optimum convection current between the glass, ensuring condensation-free windows.
They are made in our own factory and fully conform to European Standard EN1279, unlike most of our competitors.
Slow-Grown Spruce
Unlike our competitors, we only use high-quality spruce timber in our garden log cabins rather than cheap pine or mixed timber. Why do we use slow grown spruce rather than the much cheaper knotty pine alternatives?
Spruce is considered more stable as it expands and contracts less than pine. This stability means that the spruce walls of our garden buildings minimise gaps appearing as the timber changes along with the weather. We responsibly source all our timber, where it grows slowly in the cold northern regions. We all know the old adage of counting the rings to see how old a tree is, well our timber grows slower, and takes longer to get to size meaning it has more rings in it. This means it has a tighter grain, and each ring helps prevent cracks and shakes appearing in the densely packed timber.
Our garden buildings really are built to last therefore we use only the highest quality, slow-grown spruce. Spruce is much more resilient to warps and splits compared to its cheaper alternative pine. Being a whitewood, it doesn’t discolour anywhere near as much as pine so it is also much more aesthetically pleasing for a log cabin. Considered more stable, less knotty and resinous than pine, spruce will also produce a lot less sap. It is also less dense meaning it is not as susceptible to mould and rot.
Many manufacturers use a mix of timber saving them money. They will buy the lowest cost timber and then mix these up during production, often using finger joints. Ending up with a cabin, where the walls are a mix of pine (redwood) and spruce (whitewood). Not only does the log cabin then look comical, with stripy walls of different timbers, but this just shows a lack of pride about the finished product.

Adjustable Hinges and Friction Stays - Avon
Our expertly joined windows come with stainless steel friction stays, typically found on the uPVC windows in your home. This eliminates the needs for the typically found stay arm openers, commonly used on log cabins.
We’ve all, at some point in our lives, left the window open and it suddenly starts to rain. Usually, this would be an issue for normal window hinges. However, there’s no need to panic about rusty hinges with our domestic stainless-steel hinges.
We also include heavy duty easy-adjust hinges for our doors which allow you to make minor changes if ever required.

Ventilation and comfort
Ventilation and circulation of fresh air is also important for the wellbeing of you and your garden building and helps to maintain a relaxed and comfortable environment inside. Flyscreens for windows give effective protection so you don’t have the annoyance of flies and other creepy crawlies.
Durable materials
The fly mesh is made of strong and water-resistant materials to last.
Easy to fit
It is provided as a simple ready to install screen to fit the size of your garden room or log cabin window and fixes to the window frame. Easy to follow instructions will be provided alongside your order.
Easy to use
The roller flyscreen is easy to operate, with a handle to pull it down when the window is open, and a small clip will keep the screen in place. When not in use, the retractable flyscreen design allows it to be discreetly hidden away.
