If you know about U-values (which show heat loss through walls or roofs), PSI values are similar, but they look at where parts of a building join together.

Boost Your Project’s Efficiency with Accurate PSI Values: Rely on Armeec for Compliance Done Right
When you’re building for low energy use, PSI values really matter. At Armeec, we provide accurate PSI value calculations that help your project meet building rules and perform better overall. Whether you’re in Manchester, London, Birmingham, or Liverpool, we’ll help make sure your design is energy-efficient and sustainable. Instead of using rough estimates, we give you reliable figures to avoid heat loss and meet the latest standards. With Armeec on your side, you can build smarter, save energy, and avoid delays. Let us take care of the details while you focus on creating great buildings.
What is a PSI Value?
So, what exactly are PSI values?
PSI values measure how much heat escapes through the joins between building parts, like where a floor meets a wall, or a window meets a wall. These areas are called thermal bridges and are often where most heat is lost.
Put simply, U-values cover heat loss across a surface, while PSI values show heat loss through the edges and corners. If you’re building in Liverpool, Birmingham, or London, getting these right means better energy performance and fewer problems later.
Why Do PSI Values Matter?
When it comes to energy efficiency in buildings, U-values aren’t the full picture. They measure heat loss through walls, roofs, and floors, but not through the joints where these parts meet.
That’s where PSI values help. They focus on the hidden heat loss at junctions, like where a wall meets the roof or floor. These are called thermal bridges and can let out more heat than you’d think.
Whether you’re working on a home in Manchester, London, or Birmingham, using accurate PSI values helps improve energy performance and ensures your design meets building regulations without guesswork.
The Hidden Culprit: Thermal Bridges
Thermal bridges appear where two building parts join, like where a wall meets the floor or a window joins a wall. These spots often have:
Geometric complexities:
Heat loss can be missed when measured from the inside or seem worse when measured from the outside.
Construction Issues:
Some materials used at these joints, such as concrete blocks, let more heat escape than the rest of the insulation. Whether you're in Liverpool, London, or Manchester, understanding these junctions is key to improving your building’s energy performance and meeting UK standards.
Where do PSI values come into play?
- Designing low-energy buildings
- Retrofitting existing structures for better performance.
- Meeting Part L building regulations in the UK.

The Impact of Ignoring PSI Values
Thermal bridges may look small, but they can cause big problems:
Increased Heat Loss
Heat escapes faster through these weak spots, meaning higher bills and less energy efficiency, especially in colder places like Manchester or Liverpool.
Condensation and Mould Growth
Cool areas can collect moisture, leading to damp and mould. This can damage your home and affect your health by making the air less safe to breathe.
Reduced Thermal Comfort
Cold patches near thermal bridges make rooms feel chilly and uneven, making it hard to keep your home warm and cosy, especially during a typical London winter.
The Solution: Optimizing PSI Values
By accurately calculating and addressing PSI values, you can:
- Minimize heat loss at critical junctions.
- Prevent condensation and mould, ensuring a healthier indoor environment.
- Enhance thermal comfort, creating spaces that feel consistently warm and inviting.
- Ensure compliance with energy regulations, avoiding penalties and delays.
How Are PSI Values Calculated?
Working out PSI values takes careful planning, smart tools, and expert knowledge. Here’s how we do it:
Analyze Material Properties
Every part of a junction, insulation, bricks, gaps, lets heat through differently. We check how thick they are and how they’re placed. In cities like London, this is key for energy savings.
Evaluate Junction Geometry
Some junctions are simple, like two walls meeting. Others are tricky, like corners in a Liverpool loft. The more complex the shape, the more chance for heat to escape.
Think about the Weather
The bigger the temperature difference between inside and outside, the more heat tries to leave. Wind and dampness in places like Manchester can also affect this.
Use Specialised Software
We use expert tools to simulate heat flow. These tools handle the maths and show us where the energy is being lost.
Identify and Address Thermal Bridges
The results show weak points. We then give advice on how to improve your design and make your building more energy-efficient, especially useful for colder cities like Birmingham.

Why Do We Succeed
Our PSI Value Assessment Process
01
We start by looking closely at your plans and design goals. Whether you're building in Manchester or Birmingham, we’ll find areas where heat might escape and help improve your building’s energy use.
02
In places like London, we use advanced software to check how heat moves through your building’s joints. This lets us understand how your materials and layout affect energy performance.
03
For projects in Liverpool and beyond, we carefully find spots where heat is escaping, these areas, known as thermal bridges, are often the cause of higher energy bills and discomfort.
04
We give you a clear report showing your PSI values and how well your building design meets UK rules. These insights help you avoid delays and get fast building approvals.
05
Depending on what we find, we suggest changes, like better insulation or design tweaks, to cut heat loss. Every solution is made to match your specific project and budget.
06
From start to finish, we’re with you. Whether it’s help with planning approval or solving a design issue later on, we’ll make sure your building stays warm and energy efficient.
