Frequently Asked Questions

What types of insulation do you use?
  • EPS (Expanded Polystyrene)
  • Mineral wool
  • Phenolic insulation
  • XPS (extruded Polystyrene)
  • Wood Fibre Insulation
What finishes are available?

We off over over 1,000 colours and texture to choose from. We can also cater for brick slip finish and dry dash.

What Uvalue is achieved?

Uvalue for retrofit the SEAI requirements is 0.27 W/m²k

Uvalue for new build requirements is 0.18 W/m²k

We have supplied several ‘passive house’ systems with Uvalue as low as 0.10 W/m²k

We can calculate this for you – Contact us

How long does the job take and is there much disruption?

Depending on the size of the house, work will typically be completed in two to three weeks. All work is done outside, and our Approved Installers take great care to ensure there is minimum disruption and that everything is left neat and tidy.

How do you deal with existing pipes and services?

All pipework is extended and returned back into the existing outlets. All other connections (electricity, gas, TV) are dealt with in accordance with the guidelines issued by the utility companies.

I have little or no eaves overhang to work with, can my home be externally insulated?

Yes, it can. An aluminium profile is used to protect the top of the External Wall Insulation System (EWI) where there is not enough eaves overhang to cover the system at that point. The roof may also be extended to allow for the EWI system.

What thickness of insulation used?

It can vary depending on what Uvalue type of insulation you are using. We have supplied projects using 20MM board to 300MM.

The most common insulation thickness is 100MM EPS for retrofit.

The most common insulation thickness is 160MM EPS for new build.

Is the system NSAI approved?

Yes, the Baumit system is approved under NSAI Agrément Certificate 09/0336.

There is a certified excess design life expectancy of 30 years for retrofit.

There is a certified excess design life expectancy of 60 years for new build.

What will it cost?

There are too many variables to give an estimation without visiting the property. Everyone’s home is different, i.e. size of property, insulation type, thickness, and finish option, to name a few.

We can recommend an approved installer who would be pleased to carry out a survey and provide a quote specific to your property.

Are there grants available?

Yes, grants are available for External Insulation through SEAI and Better Energy Home Schemes.

  • Apartment/mid Terrace – €2,750
  • House Semi-Detached/end Terrace – €4,500
  • Detached House – €6,000

We recommend you check if you are eligible for these grants before starting any works.

What happens around my window?

It is essential that window reveals and sills are dealt with correctly to ensure that cold bridging is avoided. Window reveals are cut back where necessary and covered with an insulation layer. Existing window sills are cut back, covered with insulation and a powder coated aluminium oversill is fitted.

The colour can be selected to meet your requirements.

We can also do resin coated cills.

What happens at plinth level?

As part of our External Wall Insulation System range, we offer a specifically designed Plinth System which uses a high-density insulation board.

What is External Wall Insulation (EWI)?

External Wall Insulation (EWI) is the placement of insulating boards on the external surface of all the vertical walls of a building. This protects the building from fluctuating weather conditions, reduces heat losses from inside the building and will prevent external temperature changes from affecting the interior climate. EWI keeps homes warm in winter and cool in summer, ensuring a home with a pleasant atmosphere by eliminating sharp and high changes in indoor temperature. EWI will also reduce energy consumption in terms of energy consumed for heating and cooling.

It is a common method used in Europe and throughout the world of insulating homes and commercial building.

Why use External Insulation?

Initially, the main reason for choosing an External Wall Insulation solution is that EWI will achieve higher thermally insulating results by protecting the walls from changes in outdoor temperature, taking advantage of the thermal capacity of the existing walls and more effectively avoiding thermal bridges.

Therefore, with EWI, the maximum possible reduction in heating or air-conditioning costs can be achieved. Another reason for opting for EWI is to enhance renovations. If renovating the exterior of a building, opting for an EWI solution provides great flexibility for architectural and design choices.

The disadvantage of indoor thermal insulation is the reduction of floor space in the house from the installation of the thermal insulation. In addition, the decommissioning of any objects found on the walls such as built in storage, wardrobes and radiators for example, and their subsequent reinstallation is time consuming and costly.

Can External Insulation be used on a new build or retrofit?

Yes, it can be used on retrofit or new build. It can also be used on commercial building.

Can External Wall Insulation be fixed onto any common substrate?

External insulation can be fixed onto most substrate, for example:

  • Block wall
  • Masonry wall
  • Brick wall
  • Carrier board
  • Dash finish surfaces
  • Painted surfaces
  • Mass concrete
  • And more
