EcoPro Summerhouse Insulation Kit – High Performance Garden Room Insulation

Insulate your summerhouse, garden room, garden office or timber shed with the EcoPro Summerhouse Insulation Kit. Designed for roofs, walls and floors, this is one of the highest performing summerhouse insulation solutions available in the UK — keeping timber buildings warmer in winter and cooler in summer.

Ideal for garden offices, workshops, therapy rooms, gyms and any timber building used throughout the year. If you’re searching for the best insulation for a garden room or summerhouse in the UK, EcoPro is built for exactly that.

High Performance Summerhouse and Garden Room Insulation

EcoPro combines 6 layers of reflective foil and insulating wadding to significantly reduce heat loss and improve thermal performance in garden buildings.

At just 15mm thick when open and approximately 6mm when installed, EcoPro provides excellent insulation without sacrificing valuable internal space — a key advantage over bulkier alternatives like rigid board or mineral wool.

Its thermal performance is comparable to around 50mm of rigid insulation board or 100mm of mineral wool, making it one of the most space-efficient summerhouse insulation options on the market.

Keeps Your Garden Room Comfortable All Year Round

The reflective foil retains warmth during colder months while reflecting excess heat in summer — creating a more consistent, comfortable temperature inside your garden building throughout the year. When fully taped and sealed using ThermaSeal Foil Tape, EcoPro also acts as a vapour control layer to help manage moisture and condensation.
