External Wall Insulation.
An insulation wrap to keep your house warm.
EWI consists of tested materials for insulating the exterior of buildings. Insulating boards are applied to the exterior of a building and covered with several layers of protective and decorative render, also known as a Wrap or Tea-cosy. We work with SEAI grants too, so get in touch to discuss your requirements.
The benefits of installing EWI.
External Wall Insulation (EWI) offers numerous benefits for your home. Here’s how EWI can enhance your living experience:
1. Enhanced Thermal Comfort
EWI significantly reduces heat loss, maintaining a warm home in winter and a cool home in summer.
2. Energy Efficiency and Cost Savings
Lower your energy bills and reduce your carbon footprint with improved energy efficiency.
3. Improved Home Appearance
Choose from a variety of finishes to update and beautify your home’s exterior.
4. Increased Property Value
Homes with EWI are more attractive to buyers, enhancing market value.
5. Damp and Condensation Reduction
EWI keeps walls warm, preventing dampness and condensation, and improving indoor air quality.
6. Noise Reduction
EWI acts as a sound barrier, reducing external noise for a quieter home environment.
7. Grant Eligibility
Take advantage of SEAI grants to offset installation costs, making EWI more affordable.
8. Enhanced Durability and Protection
EWI provides an extra protective layer against weather, extending the life of your home’s exterior.

That really depends on the construction of your building. The general guidelines are a thickness of between 100mm to 200 mm depending on target U-Value. The u-value target required for NEW-Build NZEB walls = 0.18 W/m²K.
-
U-value is measured in W/m²K (Watts per Metres Squared Kelvin). Basically U-Value represents the heat loss within a building or through materials (doors, windows, blockwork, roof, flooring etc.). Lower U-Value is always better, better heat retention, better energy efficiency and most importantly…. lower heating costs.
-
A simple box shape is always easier to cover then a building with lots of corners and angles. It also depends on the thickness/ target U-Value. Usually, the price for a NSAI approved EWI system will come in at around £160.00 - £250.00 SQM.
-
Well that’s easy… EWI is Top Dog for many reasons. Better U- Values, space saving, easier access and good looking! Although we do need some good weather for installation! They both have their advantages and disadvantages, both serve a purpose. For example, you cannot use EWI on stone buildings, therefore IWI would be the correct choice.
