The Science of EuroFoam

Find all this confusing?

Here are a few short explanations on some of the terms we use on this site and an explanation of our product and services.

EuroFoam - The two types of EuroFoam available are Open Cell & Closed Cell

Open-Cell Insulation

Open Cell foam insulation is developed specifically for use in homes. It is made up of tiny cells of foam that are not completely closed. The broken cells fill with air, hence occupying all the ‘open’ space inside the material. Open-Cell expands 100 times its original volume, sealing all voids, gaps and crevices. It helps provide a sealed thermal and air tight building envelope, eliminating heat loss and creating a comfortable healthier indoor environment. The thermal conductivity of open cell EuroFoam is 0.037W/mK . 

• 96% Open Cell breathable soft foam insulation.
• Light Weight and low density.
• Low Thermal Conductivity 0.037W/mk
• Certified
• New and retrofit
• Domestic and residential applications

Open Cell 800 U-Value's

Pitched Roofs Ceiling Level New Construction

U-Values for tiled or slated pitched roof, ventilated roof space, insulation placed between and over joists at ceiling levels.

Note: These values are based on the following construction (external to internal)

• Conventional tiled or slated pitched roof 
• Ventilated roof space
• Timber ceiling joists at 400mm centers
  
• Foam insulation (92%) / timber rafters (8%) (insulation and timber depths as indicated above)
• Vapour check barrier
  
• Plasterboard 12.5mm
• 3mm gypsum skim coat finish 

• Conventional tiled or slated pitched roof 
• 50mm ventilated space over breathable roofing felt
  
• Timber ceiling joists at 400mm centers
  
• Foam insulation (92%) / timber rafters (8%) (insulation and timber depths as indicated above)
• Vapour check barrier
  
• Plasterboard 12.5mm
• 3mm gypsum skim coat finish 

• Concrete block outer leaf (100mm) with external render

• Foam Insulation (85%) and timber studs (15%) (Insulation and timber depths as indicated above)
• Vapour check barrier
• Plasterboard - 12.5mm
• 3mm Gypsum skim coat finish
  

• Foam Insulation (89% / Timber joists (11%) 150mm (insulation full depth of timber joist)
  
• Floorboards 19mm
  

Closed - Cell Insulation

Closed-Cell foam differs from its open-cell counterpart in that all of its tiny foam cells are closed and packed tightly together. They are filled with a gas that helps the foam rise and expand to become a greater insulator. It provides insulation to a structure, prevents condensation, and water penetration. Its rigidity provides added structural integrity to your building and it also acts as a secondary moisture vapour barrier reducing the risk of moisture intrusion.
