Solid Wall Insulation Eco-Versal
Solid wall insulation is designed for buildings with no cavity walls, helping to prevent heat loss through solid brick, stone, or concrete.
What is wall insulation for solid wall?
Wall insulation for solid walls creates a continuous insulating layer across the wall surface. It can be used on either the inside or outside of a wall.
Unlike cavity walls, which have a space to hold insulation, solid walls have no such gap. The insulation is applied directly to the wall surface.
What is solid wall insulation used for?
Solid wall insulation is used on the internal or external walls of properties built with solid brick, stone or concrete. It is applied in either of the following methods.
Both methods help properties meet UK Building Regulations (Part L) for thermal performance.
External solid wall insulation
This is where you fit the insulation to the outside wall surface to form a continuous protective thermal shell. It is ideal when you do not want to lose indoor space or disturb interior finishes. It also gives exterior walls a fresh, rendered finish.
In some conservation or listed buildings, planning permission may be required.
Internal insulation for solid walls
Internal solid wall insulation involves fitting insulated plasterboards or rigid insulation boards inside the building.
It is the ideal solution for buildings where exterior changes are not possible or permitted, such as listed properties. A vapour control layer is often recommended to prevent condensation within the wall.
Types of solid wall insulation in UK
At Insulation Wholesale, we stock a wide range of solid wall insulation materials from trusted UK brands. Some of our popular offerings include:
- EPS (Expanded Polystyrene) Boards: Lightweight, affordable, and moisture-resistant. Ideal for external wall systems.
- XPS (Extruded Polystyrene) Boards: Dense, durable, and perfect for areas exposed to damp or heavy wear.
- Mineral Wool Insulants: Offer superb fire resistance, sound control, and thermal performance.
- Phenolic Boards: Thin yet highly efficient. Great for tight spaces. Offers one of the lowest thermal conductivity values among rigid insulants.
- PIR Boards: Deliver excellent heat retention and easy installation. A popular choice for internal wall systems.
Each type brings unique advantages, and you can choose based on your project’s specific requirements.
Benefits of solid wall insulation
A properly fitted solid wall insulant offers many benefits, including:
- Retain more heat and reduce heating demand.
- Lowers energy bills: Better efficiency means real savings year after year.
- Improves comfort: Eliminates cold spots and creates even, cosy temperatures throughout your home.
- fewer cold spots, and more even temperatures.
- Upgrades property value: Boosts your home’s Energy Performance Certificate (EPC) rating.
- Reduces condensation and damp when correctly installed and ventilated: Creates a warmer wall surface that helps prevent moisture build-up.

FAQ
What is solid wall insulation UK?
In the UK, solid wall insulation is used for properties built without wall cavities. These are often older brick or stone homes. It adds an insulating layer to either the interior or exterior surface of your walls and is an effective solution to enhance warmth and minimise heat loss.
What is solid wall insulation made of?
It can be made from a variety of materials, including EPS, XPS, PIR, phenolic foam, or mineral wool. Each type offers its own benefits, often combining fire resistance, acoustic insulation, and exceptional thermal performance. Some materials, such as phenolic foam, offer high thermal insulation in thin profiles and are a good choice when indoor space is limited.
What is external solid wall insulation?
External insulants for solid walls are available as insulating boards and are fixed to the outer wall surface. The insulation is then covered with a waterproof render or decorative finish. It keeps the home interior warm without affecting interior space, and can give your property a fresh new look.
How to install solid wall insulation?
Installation depends on whether you’re insulating internally or externally.
- For external systems, attach insulation boards to the outer walls, add mesh reinforcement, and finish with render.
- For internal systems, fix insulated plasterboards or battens to interior walls, skim and apply finishing coats to the surface.
Ensure airtightness and vapour control details are correctly integrated to prevent moisture issues.
Always follow the manufacturer's guidance or consult a professional installer for the best results.
How much does solid wall insulation cost?
The cost of solid wall insulation depends on factors such as the material used, wall area, and method of installation. On average, external wall insulation is pricier than internal systems but offers better long-term performance and savings.
