How long will it take to install?

External Wall Insulation on average takes about 2-3 weeks from assembly to dismantle of the scaffolding. As with most building works the installation is weather dependent and may create some delays.

Will there be any disruption to me? Will it be messy and noisy?

Whilst work is ongoing on the property, disruption 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 installer will continue throughout the programme.

Will my garden be affected / damaged?

The best care and attention will always be paid to the property by the installing contractor during the works. In certain circumstances, where existing plants/ trees directly interfere with the installation of the EWI system, they may need to be removed. You will be informed of this by the installing contractor/ main contractor prior to removal.

What would I need to do before work starts?

There is no need to vacate the house or even move the furniture, as all the work takes place outside, the installer will organise everything required including:

  • Climbing plants and shrubs will be removed from wall surface
  • Attached gates and sheds will be dismantled
  • Satellite dish will be removed from wall and fixed to scaffolding
  • Flues and overflow pipe will be extended to accommodate the insulation
  • Down / soil pipes will also be adjusted to suit
  • Walls will be brushed down to remove any loose debris
  • Any algae or lichen will be removed and fungicidal wash applied

Do I need to be present whilst work takes place?

You will not need to be present during the application of the EWI system, as all of the works are carried out to the external façade of the building and access to the inside of your property is not required.

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 will be applied with 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 durable is it?

All systems are designed to have sufficient resistance for areas where general wear & tear and 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?

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

What warranties are offered for the system?

The system is covered by a manufacturer’s 10 year warranty relating to labour and materials, however extensions may be applied for which may carry an associated cost.

After my walls have been insulated can I fix anything to them?

Items such as satellite dishes, gate posts, hanging baskets, etc. that are identified at survey stage will have timber fitted to support the fixings. If you decide to fix such items at a later stage you should ensure that the correct fixings are applied and are long enough to pass through to the original wall.

  • Care should be taken so as not to compress the system as this could be detrimental to the performance and the security of the item being fixed. Fixtures must be anchored back to the original wall and not the EWI system.
  • Percussion drilling must not be used as there is a risk of snagging the mesh layer but this can be minimised by the use of diamond tipped drill bit.

Is External Wall Insulation environmentally friendly?

All Weber EWI systems are manufactured and independently audited in accordance with ISO14001 Environmental Management Standard. External Wall Insulation systems incorporate insulation materials that are CFC and HCFC-free. By nature of the thermal upgrade EWI significantly reduces pollution and improves the environment locally, as well as globally. Weber EWI Systems offer zero Ozone Depletion Potential (ODP). Most importantly, the use of a Weber External Wall Insulation system is probably the most effective home improvement measure for reducing energy consumption and therefore carbon emissions.

How is the system maintained?

General building checks and maintenance is advised to ensure the longevity and performance of the system.

What quality checks are undertaken?

All Weber EWI installers pride themselves on quality installations. Checks on site are vital for a successful project and all installers implement rigorous and regular on-site quality assurance procedures in conjunction with the system manufacturer to ensure successful handover to the client is achieved.

What decorative finishes are available?

A wide choice styles are available including a vast choice of colours, textures, pebble dash and real and simulated brick effect finishes. Colour cards and samples are available on request from your local Weber recommended installer.

How much will I save on my heating bill?

Adding insulation to your home can reduce your annual heating bills by up to £460 (€550) according to research by the Energy Saving Trust.

How much will it cost?

The cost of having External Wall Insulation professionally installed onto your home is dependant upon the size and complexity of the property and type of insulation and finish required. A guide price for a typical three-bedroom semi-detached house will be in the region of £6,000 to £7,500 (€7,200 - €9,000), although cashback schemes are available, rewarding householders with substantial sums when making energy saving improvements.

Will it add value to my property?

Yes, EWI does not reduce the floor area of your home; it will renew and improve the appearance of outer walls, improves weatherproofing and sound resistance and increases the life of your walls by protecting the brickwork. The lower heating bills and increased comfort of an insulated property should also be appreciated by potential home buyers.

What happens when the work is completed?

Upon completion of the works, a supervisor from the installer will inspect the work to ensure that the installation has been carried out to a high standard and that the property has been left in a clean and tidy state.

What do I do if I have any questions?
