Description

The Warmalog® is a unique and revolutionary type of Log Cabin. A built-in 62mm sandwich of timber and polyurethane insulation helps to insulate the building, and is far easier to construct than a traditional insulated cabin. This Rhine is extended and connected with a unique metal connector to give you two separate rooms to decorate however you please. The price includes our 60mm roof50mm insulated floor and the pressure treated floor bearers, which are guaranteed to stay free from fungus or insect infestation for up to ten years after installation. We believe in your security: the doors carry a secure 4-point locking system, unlike our competitors, and the windows have multi-point espagnolette locking.


Forget seasonal garden buldings. With our Warmalog® insulated cabin, you can sit in comfort throughout the year. Not only does the Warmalog® have far better heat retention than an uninsulated cabin, the Warmalog® even has advantages over other insulated cabins. Our all-new combination of insulation materials in the walls, floor and roof make the Warmalog® much quicker and easier to construct than a traditional insulated cabin where the insulation material is a whole separate element.

You must have a solid concrete base that is square and level to successfully build this insulated log cabin.  For the Rhine Warmalog® this base should measure 4.0m x 6.0m. 

The only extra items needed are a superior quality light coloured 'Barn' paint to seal the outside, and a silicone sealant for the joints after decorating. These are available from your local decorator supply store. After you have sealed these, your decoration choices are unlimited! 

This extended Warmalog® is presented in a very simple way so that you can turn it into whatever you need it to be. It has two rooms, separated by a solid door. Perhaps a room for you and a room for the kids! Harmonise the decoration between the rooms, or let your partner indulge their strange tastes with a room to themselves. Home office, music room, a gym or even a bar ... .  The possibilities never end. With a Warmalog® you can be sure that the passing of the seasons is not going to restrict your use of your special space.

Not only the walls of the Warmalog® Cabins are insulated. The floor has a 50mm insulated structure and the roof has 60mm. The Double-Glazed windows are 24mm thick including 2 panes of 4mm toughened glass. These and other carefully designed thermal features produce a U value of 0.59 for the Warmalog® cabin. Now you can be sure that your cabin will retain its temperature in the cooler months as well as the warmer months.

Warmalog® cabins are sturdy and secure. They feature a Multi-Point Espagnolette locking system and domestic standard hinges on the extra wide-opening French Doors. Pressure treated bearers keep the damp from the base of the cabin, and up above, long hefty Purlins support the roof.

The Warmalog® is easy for you to assemble. Enjoy it year-round!

Product Features
 
Insulated Log Cabin Fully Insulated Log
Insulated Log Cabin Fully Insulated Roof And Floor
 
Fully insulated
 
The Warmalog is fully insulated, promoting heat retention and saving you money on your heating bills. We always supply Polyurethane insulation, a superior insulator than Rockwool or Polystyrene. We use 30mm thick Polyurethane insulation, sealing off the building from elements to help save energy. The Warmalog achieves a low 'U' value of 0.59, which shows it has great insulation efficiency.
 
Insulated Log Cabin Toughened Glass
Insulated Log Cabin Styrene
 
Toughened glass
 
We use 4mm toughened glass in our windows and doors for increased safety and security. 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 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 shards.
 
Insulated Log Cabin 24 mm Double Glazing
 
24mm double glazing
 
The Warmalog comes complete with 24mm sealed window units for increased insulation. This is a single, ready-to-install unit comprising of two sheets of 4mm toughened glass with a 16mm 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. Properly Insulated windows help to make you make the most of your building throughout the year, and also offer better sound dampening than single glazing.
 
Insulated Log Cabin Slow-Grown Spruce Wall
Insulated Log Cabin Slow-Grown Spruce Timber
 
Slow-grown spruce
 
We use slow grown spruce timber, which is far superior to the commonly used Pine. Spruce is less porous and so less likely to shrink, warp or split and is less susceptible to blue mould. It has fewer knots than pine and is also less resinous, which makes the possibility of sap ruining your clothes or furnishings much less likely. Slowly grown Spruce from colder climates have more densely-packed growth rings and therefore have far greater strength and durability than Pine or “mixed softwoods”, which age and weather more noticeably, leading to a striped effect on your cabin.
 
Insulated Log Cabin 4-Point Locking System
 
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?
 
Insulated Log Cabin Storm Braces
 
Storm braces
 
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. 
 
Rhine Insulated Log Cabin Separate Rooms
 
Separate rooms
 
The Warmalog Grande provides you with two rooms, separated by a single solid timber door. You must cut the hole for this door yourself, as the wall is not sent to you precut. This multi-room feature gives you many more options for how you can use the log cabin. The 62mm thick insulated walls and solid door means there is some privacy between the two rooms if you want to play loud games or make a telephone call.
