External Combustion Air & Sealed Direct-Air Supply
Combustion air and direct air kits Dundee is our dedicated service for delivering a regulated external air supply to your wood or multi-fuel stove. By drawing air directly from outside — rather than from the room — a sealed or semi-sealed connection improves efficiency, reduces drafts, and helps maintain balanced room pressure in modern homes with tight fabric and high performance glazing.
We specify and install direct-air kits matched to your appliance, route and weatherproof the air duct, and integrate any required dampers or mesh. Every installation is aligned with manufacturer instructions and Building Regulations, and can be coordinated with Flexible Flue Liners or Twin-Wall Chimney Systems for a complete, compliant solution.
GET IN TOUCH
Breathe easy.
Our combustion air and direct-air kits Dundee service ensures every woodburning stove Dundee installation burns cleanly and efficiently. By drawing air directly from outside rather than from the room, we stabilise draft, prevent smoke spillage and keep modern Scottish homes comfortable and compliant.
100%
100 % Building Standards compliance on every direct-air system we install across wood burners Scotland. We coordinate with your stove make, flue route and airtightness requirements.
Why direct air matters
Modern airtight homes can starve a stove of oxygen, causing poor combustion and smoke. A dedicated external air supply feeds the fire exactly as designed, improving safety and efficiency.
System types & routing
We design sealed or semi-sealed air intakes using insulated or rigid ducting to external walls or voids, complete with grilles and dampers. All routes are tested for free-air area and weather sealing.
Survey & assessment
We evaluate airtightness, route length, bends, and manufacturer guidance to size the duct and prevent restriction. Results are recorded in your installation certificate.
0%
0 % room air loss—sealed direct-air connections prevent drafts and pressure imbalance, keeping warm air inside and your stove performing efficiently.
Sealed vs open air systems
We specify sealed direct-air kits where the appliance permits, maintaining balanced room pressure. Open systems remain available for traditional builds.

When it’s essential
New-builds, retrofits with MVHR or extractor fans, or any installation where the manufacturer mandates external air. We’ll confirm necessity during survey.
Coordination with flue systems
Our team integrates combustion air and flue design for seamless performance. We liaise on recess formation and hearth construction to ensure full compliance.
24 / 7
24 / 7 balanced performance—constant, regulated airflow keeps combustion stable in all Scottish climates, from coastal Fife to Highland frost.
Performance & comfort
Stable combustion improves flame control, reduces glass soot, and enhances heat output. Balanced air also stops cold drafts across floors.
Maintenance & inspection
Annual inspection keeps ducts clear and seals tight. Combine this with chimney sweeping and stove servicing for full care.

Combustion air and direct air kits Dundee
What we install.
Our combustion air and direct air kits Dundee service includes appliance-specific direct-air adaptors, insulated or rigid ducting to external wall/floor/void, weather-proof grilles, pest mesh, and where specified, back-draft dampers. We assess fabric airtightness, route length and bends to maintain free area, and ensure the final connection is sealed to the stove’s primary/secondary air control as designed by the manufacturer.
Why it matters.
Stoves need oxygen to burn cleanly. In modern, airtight homes, relying on incidental room leakage can starve combustion and create negative pressure, increasing smoke spillage risk. A dedicated external supply stabilises the fire, reduces cold drafts across the floor, and improves overall comfort. Paired with a correctly sized flue, direct air helps the appliance meet its stated efficiency and emissions performance.
When it’s essential.
New-builds and renovated properties with upgraded glazing and airtightness targets; homes with continuous mechanical extract (kitchens/bathrooms); rooms with intermittent extraction like cooker hoods; and any installation where the stove manufacturer mandates a direct-air connection. We’ll confirm requirements during survey and integrate them with your flue route and hearth design.
Compliance & coordination.
We follow appliance manuals and Building Regulations, verifying the effective free air area and the sealed path to the intake. Where a chimney exists, we coordinate with Flexible Flue Liners; where there is no chimney, we pair with Twin-Wall Chimney Systems. If you also need a new recess and hearth, see our dedicated service or discuss a combined programme to keep trades and timelines tight.
