Garden Annexe Insulation
Effective insulation is essential for a comfortable, energy-efficient garden annexe.
A Garden Annexes enjoys high-performance materials and construction techniques to keep heat in during winter and out in summer, reduce noise transmission and lower running costs.
Our standard specification includes insulated floors, walls and roofs with vapour control layers and detailing.
Every annexe is designed for long-term durability and low maintenance. The result: a cosy, year-round living space that remains economical to heat and delivers better sound privacy and environmental performance.
Therefore, Garden Annexes are insulated with 100mm PIR foil faced insulation in each aspect of each elevation. All walls, floors and ceilings benefit from this high performance insulation to maintain comfortable temperature in the annexe no matter the weather outside.
Importantly, each insulation component is machine-cut in our factory to 0.1mm tolerence to ensure no loss of thermal integrity.
