Energy saving

Our external wall insulation systems can help to lower U-Values and our brick slips require less energy to produce compared to traditional bricks.

Saving Energy

X-Clad and V-Clad are our external wall insulation (EWI) systems and are suitable for both new build and retrofit projects. The backer panels used for X-Clad and V-Clad are excellent insulators and will save energy and reduce heating bills.

The extruded polystyrene, PolyFoam XPS panel used in X-Clad can be supplied in a range of thicknesses up to 100mm to help meet the U-Value targets of a project. It is free from CFCs, HCFCs and any other material with ozone depletion potential.

The expanded polystyrene (EPS) panel used in V-Clad is available in 20mm thick panels, although thicknesses up to 100mm may be supplied for larger projects. It is free from CFCs, HCFCs and any other material with ozone depletion potential.

U-Values

The U-Value is a measure of how well a component of a building retains heat. The lower the U-Value, the more effective the insulant. The Building Regulations set the required U-Values for new build and refurbishment of existing buildings. Many take the opportunity of a building or refurbishment project to install or improve the insulation. The long-term benefits include improved comfort conditions for the occupiers, reduced energy consumption, lower energy bills, and greater sustainability.

We can provide project specific U-Value calculations to determine whether your proposed build up reaches the desired U-Value target. Please contact us with your project details.

This 1930’s solid wall house in Nottingham was cold in the winter and suffered from damp and condensation. Eurobrick’s 75mm X-Clad system and Britannia range brick slips were retrofitted to most of the house, with 50mm thick X-Clad used in areas where space was restricted. The U-Value of the walls improved from around 1.94W/m²K (typical for solid wall construction) to 0.36W/m²K (where 75mm thick X-Clad was installed). The before and after thermal images show the improvement to the thermal performance of the property following installation of X-Clad. Read more about this project or view video.

Environmental Impact

X-Clad polyfoam panel is free from CFCs, HCFCs and is free of any other material with ozone depletion potential.

V-Clad EPS panel is CFC, HFC and HCFC free and is free of any other material with ozone depletion or global warming potential.

A Greener Alternative

In terms of the amount of energy and raw materials used during production, and the associated carbon emissions, standard sized bricks are much more costly to the environment than manufactured (extruded) brick slips, and also have low insulation properties.

Eurobrick’s extruded brick slips from the Britannia range require only 30-40% of the energy used to produce traditional bricks, which means they are much better for the environment. Brick slips used with our cladding systems are considerably lighter than standard bricks and traditionally constructed masonry walls; permitting savings in transportation, foundations, and other structural elements whilst improving sustainability.
