Garden Pods
Foil insulation is included as standard. Pods are the entry point to our insulated ranges, with their own options and size limits.
Insulation
Garden room insulation that fits your plans
An occasional garden retreat and a room you use throughout the working week place different demands on a building. Insulation is one of the important differences to consider when choosing your Noah range.
We offer different specifications across the collection, from foil insulation in Garden Pods to the SIPS construction used for Signature. Compare the options alongside how often you will use the room and what you need it to do.
Specification & options
What does insulation do?
Insulation slows heat transfer through the building fabric. It helps reduce heat loss when you are heating the room, but it does not produce heat itself.
Comfort also depends on the wider design: glazing, ventilation, heating, the room’s position and how you use it. Consider these together rather than choosing on one material alone.
Choosing your range
Insulation across the Noah range
Garden Rooms
PIR insulation is included as standard in the walls, roof and floor. It helps reduce heat loss for a room used regularly through the year. SIPS are reserved for Signature and Granny Annexes.
Signature Garden Rooms
SIPS are included as standard in Signature, combining structure and insulation within the panels. The foundation is included too, subject to site checks.
Granny Annexes
The annexe range includes SIPS as standard. Discuss the full specification and requirements for the proposed living space with us.
Garden Buildings
Garden Buildings are our non-insulated range. If regular use in colder weather is central to your plans, compare the insulated ranges before choosing a building.

Insulated garden rooms compared by range
The U-value shows how much heat passes through a wall, roof or floor. Lower is better. Our standard Signature wall, a 100mm structural insulated panel, is rated at 0.27 W/m²K by our panel supplier, comparable to the walls of a modern new-build home.

Structure and insulation in one panel
A structural insulated panel combines an insulating core with strong outer faces. It provides support and helps reduce heat transfer through the building fabric.
SIPS come as standard on Signature and Granny Annexes. They are part of the range specification, not a separate upgrade.
Insulation and ventilation work together
Every insulated Noah building has a breather membrane outside the insulation to shed rain and let the frame breathe. Signature walls add a vented cavity behind the cladding and a foil vapour control layer on the warm side.
Ventilation helps remove moisture from everyday use. Follow the ventilation guidance for the room, particularly when heating it or using it for exercise.
Keep more of the heat you put in
Insulation slows heat loss, helping the room retain warmth from a suitable heater. Choose a panel heater or heating-and-cooling system around the room size, glazing and use.

Common questions
Garden room insulation FAQs
Are all Noah buildings insulated?
No. Our Garden Buildings range is uninsulated by design. If you need insulated garden buildings, choose a Garden Pod, Garden Room, Signature or Granny Annexe, all insulated in the walls, roof and floor.
What U-value should a garden room have?
There is no legal minimum for most garden rooms. A detached garden room with no sleeping accommodation is exempt from Building Regulations if its floor area is 15m² or less, or up to 30m² if it sits at least 1m from the boundary. Lower is better, so compare wall with wall. Our Signature wall, a 100mm structural insulated panel, is rated at 0.27 W/m²K by our panel supplier. Garden Rooms and Pods figures to confirm
Is SIPs or PIR insulation better for a garden room?
Both work well. PIR boards in a timber frame are standard on our Garden Rooms. SIPs combine the structure and insulation in one panel, with fewer joints for heat to escape through, and come as standard on Signature and Granny Annexes.
Is multi-foil insulation enough for a garden room?
For a compact pod used regularly with a small heater, yes. For a room you will work in every day through winter, PIR or SIPs hold heat better, which is why our Garden Rooms and Signature ranges use them.
Can I use an insulated garden office all year round?
Yes. Garden Rooms, Signature and Granny Annexes are insulated in the walls, roof and floor, so a small heater keeps them comfortable through winter. Garden Pods suit regular use too.
Will an insulated garden room get condensation?
Condensation can occur when moisture meets a cold surface. Insulation, appropriate heating and regular ventilation work together to reduce the risk; no room is guaranteed condensation-free.
Will insulation keep the room warm without heating?
It slows heat loss but does not create heat. With good insulation, a small heater warms the room quickly and keeps it warm for less.
Can I insulate a Garden Building myself?
You can, but speak to us before ordering so we can advise on the membrane and insulation that suit it.
