Pulse Testing

How Pulse air tightness testing works.

Pulse technology measures building air permeability with a controlled pressure pulse, giving a clean and convenient test process.

The Method

What happens during a Pulse test?

1. Equipment is positioned inside

The Pulse units are placed inside the property as part of a straightforward test setup.

2. A controlled pressure pulse is released

The equipment creates a short, controlled pressure change inside the building.

3. Sensors record the building response

The system measures how the internal pressure changes and decays, which allows the air permeability to be calculated.

4. Results are produced

The test result helps demonstrate how airtight the building envelope is and can support compliance requirements.

Benefits

Why choose Pulse testing?

Pulse testing is designed to be efficient and convenient, particularly for residential projects where a clean and professional test process is important.

Modern specialist testing equipment
Minimal disruption to the property
Occupants can normally remain inside
Useful for new builds and occupied homes

Before The Test

Simple preparation guidance.

Before attending, we will confirm the exact requirements for your property.

1

Close external openings

External windows and doors should be able to close fully.

2

Open internal doors

Internal doors are normally left open so the property is tested as one zone.

3

Avoid smoking beforehand

Occupants should not smoke shortly before the test.

4

Allow access

Clear access helps the equipment be positioned and the test completed smoothly.

FAQs

Pulse testing questions.

What is Pulse air tightness testing?

Pulse air tightness testing measures how air moves through the building envelope using a controlled pressure pulse and sensitive pressure measurement.

How long does the appointment take?

Allow around 30 minutes for a straightforward test visit, although this can vary depending on the property and access.

Can people remain in the property?

Usually yes. Pulse testing is designed to be convenient and less disruptive for occupants.

Do windows and external doors need to be closed?

Yes, all external windows and doors should be closed fully for the test.

Should internal doors be open?

Yes, internal doors are normally kept open so the test measures the property as a single internal space.

Can furniture stay in place?

Yes. Normal furniture can stay where it is, provided there is reasonable space to position the equipment safely.

What does air permeability mean?

Air permeability describes how much air leakage occurs through the building envelope for a given pressure difference.

What happens if the result is not as expected?

The result can help your project team understand the building's performance and decide what steps may be needed next.

Do you cover Southern England?

Yes, by arrangement. Please send the project location when requesting a quote.
