Advantages

Advantages of Airtight
Riser Doors

Engineered to seal riser shafts and support energy performance, pressure regimes and modern building strategies.

Reduced Uncontrolled Air Leakage

Seal riser shafts on every floor to prevent the stack effect and uncontrolled air movement that wastes energy and undermines comfort.

Building Regulations Part L

Stronger alignment with Part L energy performance requirements. Verified airtight data for SAP calculations and energy models.

Support Pressure Regimes

Critical for hospitals, offices and tall buildings where pressure controlled corridors and zones depend on sealed riser openings.

Fire + Airtight in One Product

Combine airtight and fire performance in a single doorset to simplify specification and reduce the number of products on site.

Fast UK Delivery

Manufactured and delivered in 3–5 working days from our Nuneaton facility. No import delays or extended lead times.

One Responsible Manufacturer

We design, test and manufacture the complete doorset. One product, one set of test data, one team accountable for performance.

Common Questions

Airtight Riser Door FAQ

Everything you need to know about specifying, ordering and installing airtight riser doors.

What is an airtight riser door?

An airtight riser door is a steel doorset engineered with compression gaskets and precision frame detailing to limit uncontrolled air leakage through vertical service shafts. They prevent the stack effect in tall buildings and support energy performance targets by sealing riser openings on every floor.

What standard are airtight riser doors tested to?

Our airtight riser doors are tested to BS EN 1026:2016, the European standard for air permeability of building components. Testing measures air leakage rates under controlled pressure differentials. Results are supplied as formal test reports for submission to energy consultants and Building Control.

Why are airtight riser doors important in tall buildings?

Tall buildings experience the stack effect, where warm air rises through vertical shafts and draws cold air in at lower levels. Leaky riser doors allow uncontrolled air movement that undermines heating, ventilation, and energy performance. Airtight riser doors seal these openings to support pressure regimes and reduce wasted energy.

Can airtight riser doors also be fire rated?

Yes. We offer combination doorsets that provide both airtight performance and fire ratings up to 120 minutes. This means one product addresses two requirements, simplifying your specification and reducing the number of items needed on site. Dual-rated doors are tested to BS EN 1026:2016.

How quickly can airtight riser doors be delivered?

Standard airtight riser doors are manufactured and delivered within 3 to 5 working days from our UK facility in Nuneaton. There are no import delays. For large volume or bespoke orders, contact us for a confirmed lead time based on your project specification.

Can airtight riser doors be manufactured to custom sizes?

Yes. We manufacture bespoke airtight riser doors to your exact opening dimensions in single, double, or multi-door configurations. All custom doors maintain the same airtight performance and are supplied with full test data and documentation. Compression gaskets are fitted as standard on every unit.
