FAQs

Insulated Garden Rooms in Greater London

What insulation specification do you use?
Standard insulated garden rooms use 100mm PIR (polyisocyanurate) in walls and roof, plus 75-100mm PIR in floors — giving U-values around 0.22 W/m²K. 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 in Greater London?
Insulated garden rooms in Greater London typically cost £2,000-£5,000 more than uninsulated equivalents — a worthwhile investment given the change in usability. A £15,000 uninsulated room becomes £17-20,000 insulated.
Can I heat an insulated garden room cheaply?
Yes — well-insulated rooms need very little heating. A small electric radiator or underfloor heating uses £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 — proper insulation works both ways. Combined with good shading (deep eaves, awnings, or solar-control glass), insulated rooms stay 5-10°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 — all standard in our builds. Done right, condensation isn't an issue.
