No1 in External Wall Insulation

FAQs

Q?What decorative finishes are available?
A.

A number of finishes and colours are available, designed to blend in with the existing structure. These include a range of traditional aggregate finishes and a brick effect finish. The installers can discuss this with you before work begins.

Q?How long does it take to install?
A.

Insulating an average size home will require around 9 – 10 days of work, spread over 3 – 4 weeks (to allow for drying time etc.) To minimise disruption, most people have their home insulated at the same time as having other work done.

Q?How is EWI installed?
A.

The system is installed in a number of steps. First, all external fittings will be removed. The insulation slabs are then attached to the wall — either with an adhesive or mechanically. Next, a render is applied to cover and protect the insulation, along with a decorative finish of your choice. Finally, all external fittings are replaced.

Q?Does it come with a warranty?
A.

All EWI systems are covered by a 10-year manufacturer’s warranty relating to labour and materials. An extended warranty is available for additional cost.

Q?How long does it last?
A.

All systems are tested by the BBA for life-expectancy and achieve a rating in excess of 30 years.

Q?How durable is the insulation?
A.

EWI systems are designed to withstand normal wear & tear and impacts. If part of the systems gets damaged, repair is quite straightforward.

Q?Can I have external wall insulation for a timber framed property?
A.

Unfortunately not. Timber framed properties require a ventilated and drained cavity so external insulation would provide no benefit at all.

Q?Will I need to apply for planning permission to have the insulation installed?
A.

In most cases no. However, if you live in a listed building or a conservation area you do become responsible for obtaining planning permission. Contact your local council for more information.

Q?Can damage to my external wall insulation be repaired?
A.

Yes it can. The insulation is quite sturdy by nature, however there is always the possibility that damage may occur. This can be fixed if it happens.

Q?What happens to my fixtures, such as hanging baskets, after the installation?
A.

In the vast majority of cases fixtures will be removed pre-install and then placed back after the work is complete. There is the possibility that some fixtures may not be refitted and a surveyor will provide more information is this is the case.

Q?What is EWI?
A.

External wall insulation (EWI) is a solid insulation material attached to the outside of a building and covered with a protective render. It is suitable for old or unconventional buildings that don’t have cavity walls.
