Why is garden room insulation essential?

Garden room insulation is crucial for several reasons, primarily for increasing functionality, energy efficiency and overall comfort of the building. It helps to prevent damp concentration and avoid lingering moisture, which could damage the structural integrity of the wooden building.

Even though these compact structures are not used as primary residences, insulation for a garden room is a must to ensure a pleasant indoor temperature and overall comfort whenever you spend time in it.

Year-round living and structural longevity of an insulated garden room

Temperature fluctuations in an uninsulated garden room might affect the structural and finishing materials, furniture or other components of the building. The proper temperature maintained by reliable insulation, on the other hand, will enhance the structure's lifespan and provide year-round comfort.

Moreover, with proper garden room insulation, you can rest assured that the building’s longevity is ensured. Our insulation package options several insulation levels: uninsulated, insulated (basic level) and insulated+. The latter features 50 mm insulation material for the floors, 100 mm for the walls and 150 mm for the roof. The latter allows you to stay comfortably in your garden leisure oasis during all months of the year.

Which type of garden room insulation should you choose?

Most of our garden rooms are available in basic or PLUS (residential grade) insulation levels.

A basic insulation level ensures optimal thermal comfort for extended stays throughout the year. This version features 25 mm thickness insulation material, which is used for the floors, walls and roof, providing warmth and cosiness during any month of the year.

Thermal insulation PLUS features 50 mm of insulation material used for the floors, 100 mm for the walls and 150 mm for the roof so that the utmost level of comfort is ensured. PVC windows and doors are also included in the price when choosing this type of insulation for a garden room.

How to insulate a wooden garden room: everything you need to know

Regarding wooden garden room insulation, several key areas need to be considered. First, it’s essential to ensure the building is well assembled and does not feature any gaps and holes that could lead to excess moisture accumulation. After you check all the areas, the first step would be installing the floor insulation.

For reference, let’s talk about one of our construction types: twin-skin and a step-by-step process of winterproofing this structure.

The insulation should be fitter between the floor joists, fixing the gaps with foil tape and covering it with the floorboards.

How to insulate the garden room walls? Walls must be insulated by inserting the insulation material in between the walls (or in between the wall and external cladding), precisely fitting it together and leaving the air gap for ventilation next to the outer wall. A breathable membrane should be fixed to the inner side of the external cladding.

Roof insulation material is installed in between the roof boards and the roof coverings (bitumen shingles, metal roofing, etc) – additional vapour barriers can be included if needed.

Last but not least, the building's efficient insulation is accompanied by high-quality PVC windows and doors for additional thermal efficiency.

Insulated Garden Room Cost: What You Can Expect

Insulated garden room cost can vary based on numerous characteristics and specifications. Depending on your selected model, a reliably thermally insulated structure might cost somewhere between £5000 and £10 000 for a basic insulation level, excluding assembly costs.

The cost of an insulated garden room could be a bit higher. Yet, it provides the most exquisite experience, allowing you to fully immerse into the benefits of your new garden room and enjoy it year-round.
