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 W5.0m x D4.0m for the Modetro Warmalog®.
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 polyurethane 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!
Polyurethane 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. Polyurethane 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 0.59. 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 0.59 is considered to be very low, meaning you’ll save a fortune on heating bills compared to Polystyrene or Rockwool insulated cabins!
Wide Opening Windows
Our garden log cabins feature key-lockable outward opening windows, so you don’t lose internal space, allowing you to accommodate furniture underneath the window. Our windows have been designed to include draft seals that prevent wind and rain from entering your garden retreat. You may think it’s over the top, we think it’s just standard.
Multipoint Locking Windows
Just like our doors, we use mushroom headed espagnolettes which pull the window tightly into the draft seals attached to the frame. We also supply a solid handle and key that allows you to lock the window whilst you’re away. We also supply Georgian Bars as standard. Most log cabin companies only supply a multi-purpose stay arm opener for both locking and keeping the window open.
Internally Beaded Windows
Both our doors and windows are fitted with internal beading used to secure the glazing in place. This beading style is typically found in uPVC windows and is a proven method of security. However, there are still some companies that externally bead their windows. Allowing intruders to remove the glazing from the outside of your garden house and gain access.
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.
AVOID PLANNING PERMISSION
Our Modetro Warmalog is less than 2.5m high
and therefore exempt from UK planning conditions and permitted development
, even if it is close to the boundary of the property. This frees you from legal restrictions and allows you more freedom to choose your ideal site. You can now consider more personal factors such as the amount of direct sunlight it’ll receive, how easy it is to access and its aesthetic appeal. If you want to find out more about permitted development rights see our planning guide
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, Not Cheap Pine
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.
PRESSURE TREATED BEARERS
All of our garden buildings have pressure treated bearers as standard. As they are exposed to the damp, cold ground. This treatment will prevent them from rot, decay and insect infestation for up to 10 years. Due to this costly but effective process, we can offer our customers a genuine 10-year guarantee against rot and insect infestation on the bearers. We only suggest that you apply a good quality water repellent to prolong the longevity of the timber.
10 year guarantee
All of our Pressure Treated Timber comes with a genuine 10-year Guarantee against rot and insect infestation. The process of pressure treatment forces the wood preservative into the timber rather than simply dip treating (essentially just covering the exterior) like many companies still do. If the timber is only dip treated then you would have to buy and apply treatment to your cabin every single year in order to maintain their worthless 'guarantee'.
Industry Leading Walkthrough Height
We were the first on the market to provide tall walkthrough height to the UK. There's no need to 'duck' on the way in through our quality French doors. With a tall walkthrough height of 6'2" (1.88m) you’re free to move in and out of your cabin concussion free. Others have tried to copy us but decided to include the doorframe as part of the walkthrough height.
AVOID SAGGING ROOF
The Modetro Warmalog features heavy duty 140mm or 210mm by 45 mm wide supporting roof beams prevent dangerous and unsightly sagging. Just like every other part of your cabin, this important part of the structure will never be glued or screwed together offcuts. We only use single pieces of timber for our purlins to provide you with a strong and stable roof.
4-point locking system
Windows and doors are at the heart of your Wamalog’s security, and we design ours to ensure that only welcome visitors can enter your building. We feature as standard, a secure four-point locking system, including: hook, locking latch and two roller cams. We combine this with a 6 pin Euro cylinder, the same type of lock cylinder you would find on the front door of a typical house. Why should your log cabin be any less secure than your home?
Adjustable hinges and friction stays
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.
To control natural expansion and contraction in the timber, the Warmalog features steel straps on the inside and outside of the cabin known as storm braces, Secured by screws and bolts, these braces are adjusted to spread the timber's natural movement equally across a much larger area, thus avoiding the worst effects of localised expansion and contraction within the wood.
