How to Choose the Wall Thickness for Your Log Cabin

Wall thickness decides how warm, quiet and solid a log building feels — and how much it costs. The simplest way to choose is to start from one question: how many months a year will the building be heated?

The options

• 28 mm solid log — tool sheds, storage and small summer shelters; offered on our smallest models.
• 44 mm solid log — the standard for summer houses, hobby rooms, garages and carports.
• 58 mm solid log — garden offices and guest cabins used from spring to autumn.
• 70 mm solid log — larger cabins and houses, and colder or windier sites.
• 44+44 mm double wall — two log walls with an insulated cavity, for buildings heated through winter.
• 70+70 mm double wall — for permanent homes in cold climates; quoted on request.

The wall options available for each model are listed on its product page and in the quote form.

Choose by use

Unheated or summer only: 28–44 mm

Storage, a summer house or a hobby room used in the warm months does not need more. A 44 mm wall is stiff enough for most garden buildings and keeps the price down.

Occasional heating in spring and autumn: 58–70 mm

A garden office or guest cabin heated now and then is noticeably more comfortable with a thicker solid wall: it holds heat longer, feels more solid and blocks more sound. A single 70 mm wall is the heaviest solid profile — but it is still not a winter wall on its own.

Heated through winter: a double wall

For year-round use in most of Europe, choose a 44+44 mm or 70+70 mm double wall with insulation in the cavity, together with roof and floor insulation. This keeps the look of solid timber inside and out while reaching the insulation a heated home needs. A single 44 mm wall is not enough for comfortable winter living.

What else keeps a cabin warm

• Roof and floor insulation — most heat escapes upwards, so insulate the roof first, then the floor.
• Windows and doors — our windows are double glazed; the premium range adds tilt-and-turn opening and better seals.
• Floor boards — 28 mm boards feel more solid underfoot than the standard 19 mm.
