Air Pressure & Permeability Testing

At Dartmoor Energy, we offer professional air pressure and permeability testing services for properties across Devon, Cornwall, and the South West. Whether you’re looking to improve your home’s energy efficiency, comply with building regulations, or meet PAS2035 ventilation standards, our expert team provides the solutions you need. We offer both Pulse Tests and Blower Door Tests to assess your property’s air permeability and identify ways to reduce heat loss and improve overall performance.

What is Air Pressure/Permeability Testing?

Air pressure or air permeability testing measures how much air leaks in or out of your property. High levels of air leakage can lead to heat loss, making your home less energy-efficient and increasing your energy bills. By conducting an air pressure test, you can:

Identify where air leaks occur in your home.
Improve heat loss calculations for better insulation and heating efficiency.
Ensure compliance with Building Regulations and PAS2035 standards.
Create a more comfortable living environment by reducing drafts and maintaining consistent indoor temperatures.

Our Testing Methods

At Dartmoor Energy, we use two main testing methods to assess air permeability:

1. Blower Door Test

The Blower Door Test is a widely used method for determining air tightness in a property. It involves installing a large fan in the main door of your home to create a pressure difference. This pressure reveals where air is leaking from the property, helping us identify problem areas such as gaps around windows, doors, or poorly sealed lofts.

This test is ideal for:

Building Regulation Compliance: The Blower Door Test is essential for new builds, extensions, and renovations to ensure they meet Part L of the UK Building Regulations.
Improving Energy Efficiency: By detecting leaks, we can provide targeted advice to improve insulation, reduce heat loss, and lower energy bills.

2. Pulse Test

The Pulse Test is a cutting-edge alternative to the traditional blower door test. This method involves a brief pulse of air pressure inside the property, offering a more natural way to test for air leaks. The Pulse Test can be conducted quickly, making it a convenient option for occupied properties.

This test is ideal for:

Quick Turnaround: Pulse testing is faster and less intrusive, making it a perfect option for homeowners who want minimal disruption.
Ventilation Checks: This test can also help ensure proper ventilation levels are maintained within your home, aligning with PAS2035 ventilation requirements.

Benefits of Air Pressure & Permeability Testing

Accurate Heat Loss Calculations By identifying air leaks and improving your home’s airtightness, you can make more accurate heat loss calculations. This helps determine the most effective insulation and heating solutions, ensuring that energy efficiency improvements are fully optimised.
Compliance with PAS2035 If your property is undergoing an energy retrofit under PAS2035, air permeability testing is crucial for verifying that ventilation requirements are met. Our tests ensure that your home’s ventilation is properly balanced, preventing dampness, poor air quality, and heat loss.
Meeting Building Regulations For new builds, renovations, and extensions, air pressure testing is required to comply with Part L of the Building Regulations. Our services ensure that your property meets these essential standards, and we provide all the necessary documentation to support your compliance.
Improved Comfort & Lower Energy Bills By sealing air leaks and improving airtightness, you can create a more comfortable home environment. This reduces drafts, maintains stable indoor temperatures, and lowers the need for excessive heating, leading to lower energy bills over time.
Sustainability & Environmental Impact Reducing air leakage not only makes your home more energy efficient but also lowers its carbon footprint. A tighter, more energy-efficient home means using less energy, which is better for the environment and aligns with long-term sustainability goals.
