Successful application dates back within the UK since the mid 1980s, with External Wall being one of the main forms of construction within mainland Europe.

How durable is it?

All systems are designed to have sufficient resistance for areas where general wear and tear, impact is expected. Additional security can be specified for areas requiring high impact resistance. However,
where, damage is sustained, through accident or vandalism, replacement and repair is easily achieved.

What is the life span of the system?

By nature of the thermal upgrade EWI significantly reduces pollution and improves environment locally, as well as globally.

Mark Group only offers External Systems which achieve zero Ozone Depletion Potential (ODP).

How will the system be installed?

The system will be installed in a number of key stages. All the external fittings will be removed or redirected,
the insulation slabs may have an adhesive and/or a mechanical fixing, followed by the applications of a render system to provide protection and a decorative finish. Upon completion, all external fittings are then repositioned.

How long will it take to install?

EWI is an extensive refurbishment programme of the property and often carried out in conjunction with other works on the property, i.e. facia and soffit, rainwater goods. Therefore the time spent on site can be significant compared to traditional insulation
measures. Based on an average sized dwelling a typical install time will be around 9 to 10 days on site over a period of 3 to 4 weeks to include for drying times, replacement of any attachments, etc.

What decorative finishes are available?

A wide choice of colour texture and styles are available including brick effect finishes.

Will there be any disruption to the tenant?

Whilst work is ongoing on the properties, disruption to the tenant will be minimal. However as part of the
installation process drilling and mixing machines will be in use whilst work progresses. Ongoing liaison with the tenant will continue throughout the programme.

What quality checks are undertaken?

Mark Group prides itself on quality installations and EWI is no exception. In fact the number of installation trades and complicated detailing on any one project means regular management and quality assurance. Checks on site is vital for a successful project.

Mark Group implements rigorous and regular on-site quality assurance procedures in conjunction with the system manufacturer to ensure successful handover to the client/tenant is achieved.

How is the system maintained?

All of the systems are designed to be virtually maintenance-free and self-cleaning. As with good normal building maintenance, checks are required on movement joints, rainwater pipes etc and general building maintenance is advised to ensure the longevity and performance of the system.

Can I get funding?

Yes, Grant Funding is available (subject to application conditions).
