A well-insulated garden house not only ensures more well-being, garden tools and stored objects are also protected from the weather. An additionally insulated floor keeps frost out of the subsoil. At the same time, the interior of the cottage does not overheat on hot days. Insulation that you can easily do yourself is a sensible investment for almost every garden shed.

Optimal insulation of the walls
The following applies here: The thicker the insulating layer, the better the effect. Solid materials with a thickness between half and five centimeters are suitable for cladding the outer walls. The following are almost always used here:
- styrofoam
- Styrodur
which are attached to the walls using wooden formwork. It is important that the layer is well sealed so that no moisture can penetrate into the wood. You can seal any remaining grooves and joints with silicone.
The interior walls are additionally insulated with materials such as wood wool, hemp fibers or mineral wool. When buying, make sure that the insulating materials used are fireproof, only then are they suitable in connection with wood.
Floor and roof insulation
Cold always comes from below, which is why this insulation measure is particularly important for a pleasant climate.
Let's start with the ground:
- First cover the floor area with profiled wooden boards. In any case, these should be treated in advance with wood protection paint.
- Insert insulating foil, insulating material filling made of Styrofoam or Styrodur and another layer of foil.
- Floor boards are then laid over the insulating layer.
The second step is the roof:
Depending on the construction, insulation mats or loose insulation materials that are injected through a hole drilled in the ceiling are well suited for this. A roof covering with bitumen shingles, which is available in many beautiful colours, or laying roofing felt also has an insulating effect and make the house weatherproof at the same time.
Don't forget windows and doors
The best insulation is useless if it pulls through gaps in doors and windows. Not only does heat escape here, moisture can also penetrate; a musty room climate instead of the desired homely atmosphere would be the result.
Silicone, which is simply injected, is very suitable for closing joints. Window and door frames can also be sealed with a sealing tape, as is also known for household use. More luxurious, but especially in a garden house (€24.90) that you also want to use in the cold season, is double glazing of the windows.
tips
When insulating the garden house, make sure that no cold bridges form. Moisture could condense here, leading to mold growth.
