What is a Twinskin?INSULATION – WHY THE TWINSKIN LOG CABIN IS THE BEST SOLUTION
In our opinion, there is only one economic way to ensure that a log cabin can be used throughout the year, regardless of the season.
The key lies in the insulation of the log cabin. A Twinskin construction has insulation in the walls as well as in the roof and floor, which is achieved by building a cavity into the wall that can then be filled with various types of insulation.
The insulated walls can perform at the equivalent thermal value of a solid wall which is 5 times thicker, thus saving both space, materials and most importantly, cost.
It is worth reviewing how a log cabin is constructed before looking at the various options:
- Log cabins are built without the use of a vertical framework which would hold the walls at a set height. They are composed of horizontal logs which lie on top of each other and are taller during the Autumn/Winter.
- The walls are usually 17 logs high and each log can absorb enough atmospheric moisture during the Autumn/ Winter that they can each swell by 1mm, so the log cabin could be 17mm higher during the Autumn/Winter.
Log cabins are normally insulated in one of 3 ways:
1. Dry lined over studwork - a standard log cabin with a single thickness of log wall is lined out with framing and plasterboard or similar material.
3. The "Twinskin" - a log cabin method is to build a second, fully interlocking cabin inside.
The photo above show how a typical 45mm Twinskin cabin is constructed. Log cabins constructed with 35mm or less walls do not have corner bolts as the timber is too thin to drill large enough bolt holes into without compromising the log strength, therefore conventional timber wind braces are used.
Twinskins of 60mm or thicker logs have a 90mm insulation cavity for an even better thermal value.
We offer the following Twinskin options:
1. 28mm inner and outer log with 50mm insulation cavity
2. 35mm inner and outer log with 50mm insulation cavity
3. 45mm inner and outer log with 50mm insulation cavity
4. 45mm inner and outer log with 90mm insulation cavity (complies with Part L Building Regulations for habitation)
5. 60mm inner and outer log with 90mm insulation cavity (complies with Part L Building Regulations for habitation)
6. 70mm inner and outer log with 90mm insulation cavity (complies with Part L Building Regulations for habitation)
