FAQs

Insulated Garden Rooms questions answered

What insulation specification do you use?
Standard insulated garden rooms use 100mm PIR (polyisocyanurate) in walls and roof, plus 75-100mm PIR in floors β€” giving U-values around 0.22 W/mΒ²K. Premium spec uses 140-150mm PIR for U-values approaching 0.15. We avoid mineral wool in walls due to moisture concerns in compact builds.
How much more does an insulated garden room cost?
Insulated garden rooms typically cost Β£2,000-Β£5,000 more than uninsulated equivalents β€” a worthwhile investment given the change in usability. A Β£15,000 uninsulated room becomes Β£17-20,000 insulated.
Can I heat an insulated garden room cheaply?
Yes β€” well-insulated rooms need very little heating. A small electric radiator or underfloor heating uses Β£15-40/month in winter, even with all-day use. Air-source mini-split heat pumps are even cheaper to run for larger rooms.
Will it be cool enough in summer?
Yes β€” proper insulation works both ways. Combined with good shading (deep eaves, awnings, or solar-control glass), insulated rooms stay 5-10Β°C cooler than uninsulated ones in heatwaves. A small air-conditioning unit handles extreme heat if needed.
Is condensation a problem in insulated buildings?
Only if poorly built. Proper construction includes breather membranes, vapour-control layers, ventilated cavities and trickle vents β€” all standard in our builds. Done right, condensation isn't an issue.
