How much insulation do I need for a garden room in Scotland ?

The amount of insulation you need for a garden room in Scotland depends on a few factors, such as the size of the room, the type of insulation, and the intended use of the room. In general, a 100mm insulation thickness in the roof and floor is a good starting point for a garden room in Scotland, 50mm insulation in the walls is sufficient for a low occupancy use room under permitted development garden room regulations, but you may need more or less insulation depending on your specific situation.

If you plan to use your garden room as a year-round living space, you will need more insulation than if you plan to use it only during the summer months. The walls, floor, and roof should all be insulated to prevent heat loss, and the type of insulation you choose can also affect the required thickness. For example, if you choose a lower-density insulation material, you may need to use a thicker layer to achieve the same level of insulation as a higher-density material.

It’s important to consult with a professional garden room builder or insulation specialist to determine the appropriate amount of insulation for your garden room based on your specific needs and circumstances. They can also provide advice on the best insulation materials and installation techniques to ensure that your garden room is properly insulated and comfortable throughout the year.
