Brick Slip systems

Brick slip systems are an increasingly popular solution for finishing External Wall Insulation (EWI) projects in the UK. They combine the timeless appearance of traditional brickwork with the performance benefits of modern insulation technology. By applying thin brick slips to the external surface of an insulated wall, property owners can achieve the look and feel of genuine brick façades while dramatically improving energy efficiency and compliance with building regulations.

Brick slip cladding is particularly valuable in retrofit projects where maintaining the character of a building is important, as well as in new developments where speed, cost, and thermal performance are priorities. Unlike full brick construction, which is heavy, labour‑intensive, and expensive, brick slip systems deliver the same aesthetic at a fraction of the weight and installation time.

What Are Brick Slip Systems?

Brick slips are thin slices of real or manufactured brick, typically 15–25 mm thick, that are fixed to an insulated substrate. They replicate the appearance of full‑depth brickwork but are lightweight and easy to install. When combined with an EWI system, brick slips are applied over insulation boards and a reinforced base coat, creating a durable, weather‑resistant, and visually authentic façade.

Brick slip systems are available in a wide range of colours, textures, and finishes, from traditional red clay to contemporary grey and buff tones. This makes them suitable for heritage properties, modern housing developments, and commercial buildings alike.

Benefits of Brick Slip Systems

• Authentic appearance: Achieve the look of traditional brickwork without the cost and complexity of full masonry.

• Lightweight construction: Ideal for retrofit projects where structural load is a concern.

• Energy efficiency: When combined with EWI, brick slips significantly reduce heat loss and improve EPC ratings.

• Durability: Resistant to weather, frost, and impact, ensuring long‑lasting performance.

• Low maintenance: Brick slips require little upkeep compared to painted or rendered finishes.

• Design flexibility: Wide choice of colours, textures, and bond patterns to suit any architectural style.

• Compliance: Meets UK building regulations for thermal performance and fire safety when installed correctly.

Applications in the UK

Brick slip systems are widely used across the UK in:

• Residential retrofits: Upgrading older solid wall homes while preserving a traditional brick appearance.

• New builds: Providing a cost‑effective alternative to full brick construction.

• Commercial properties: Offices, schools, and retail units requiring durable, low‑maintenance façades.

• Heritage projects: Maintaining the character of period properties while improving insulation.

• Urban developments: Meeting planning requirements where brick façades are preferred.

Installation Process

The installation of brick slip systems follows a structured process:

1. Preparation – fixing insulation boards securely to the external wall.

2. Base coat application – embedding reinforcing mesh for strength and stability.

3. Adhesive application – applying a specialist adhesive to the prepared surface.

4. Brick slip fixing – placing slips in the chosen bond pattern, ensuring consistent spacing.

5. Pointing – filling joints with mortar to replicate traditional brickwork.

6. Finishing – cleaning and sealing where required to ensure durability.

This process creates a façade that is visually indistinguishable from full brickwork but lighter, faster to install, and more energy‑efficient.

Energy Efficiency and Compliance

When combined with external wall insulation, brick slip systems deliver significant energy savings. They reduce heat loss, lower heating bills, and improve comfort inside the property. They also help buildings comply with UK building regulations, particularly Part L, which focuses on energy efficiency. Improved EPC ratings increase property value and marketability, while supporting the UK’s Net Zero carbon reduction goals.

In addition, brick slip systems can be specified to meet fire safety requirements, with non‑combustible insulation and fire‑resistant adhesives ensuring compliance with current standards.

Maintenance and Longevity

Brick slip systems are designed to last for decades with minimal maintenance. Unlike painted finishes, they do not require regular re‑coating. Occasional cleaning with water is usually sufficient to maintain their appearance. Mortar joints are durable and weather‑resistant, ensuring that façades remain attractive and functional for many years.

Frequently Asked Questions

How long do brick slip systems last?
With proper installation, brick slip systems can last 30 years or more.

Are brick slips real bricks?
Yes. Brick slips are either cut from genuine clay bricks or manufactured to replicate their appearance.

Can brick slip systems be used on older houses?
Yes. They are widely used in retrofit projects to improve insulation while maintaining a traditional look.

Do brick slip systems require special maintenance?
No. They require minimal upkeep compared to painted or rendered finishes.

Are brick slip systems suitable for all climates?
Yes. They are resistant to frost, rain, and UV exposure, making them ideal for the UK climate.

Brick slip systems are a proven solution for finishing external wall insulation projects. They combine the authentic appearance of traditional brickwork with the performance benefits of modern insulation technology. By choosing a brick slip system, property owners can achieve a façade that is attractive, durable, and energy‑efficient, while meeting UK building regulations and planning requirements.

Whether you are upgrading a period property, constructing a new development, or seeking a low‑maintenance solution for a commercial building, brick slip systems deliver outstanding results.
