The past decade has witnessed a growing demand for improved energy efficiency in new build and refurbished properties. To meet the challenge lightweight insulation systems are often used to reduce the energy loss in buildings and to meet the current Building Regulation Standards for a building’s overall performance.

Concrete Repairs Limited (CRL) has responded to the demand and is currently providing a range of insulated render systems for both new build and existing structures.

In order to meet the Building Regulation standards, CRL is able to assist with advice on how to measure Thermal Transmittance (commonly known as the U-Value) to demonstrate compliance. Alternatively, Target U-Value or Carbon Index Method may be used to demonstrate compliance, but these are more complex procedures. In addition to thermal performance, the insulation system also requires a condensation Risk Analysis to ensure that `dew-point` does not occurs within the fabric of the structure.

CRL is an approved contractor for several material suppliers and is therefore in the unique position of being able to provide a range of solutions with which to satisfy the client’s requirements. EWI normally involves the installation of either expanded polystyrene, or mineral fibre in varying thicknesses. It is fixed either directly to the substrate, or on a lightweight metal frame. A render finishe can be applied directly to the board insulation, or in conjunction with an expanded metal lath, or meshcloth, to provide a more physically durable system. The rendered finishes come in a whole range of colours, textures and raised features. Raised bands, string courses and keystones, etc. can be created.

For a masonry finish, brickslips can be bonded to the render finish and pointed. Alternatively, insulated panels, or mesh panels with pre-fixed brickslips can be supplied, ready for installation on site and final pointing.

With 50 years of experience CRL has the necessary in-house skills to be able to design, manage and install insulated render systems across the UK, using the latest material technologies.
