  • Ideal for Cellars / Crawl Spaces

 

Mfoil™ Design Points

  • MFoil Single /Double sided is an insulating foil membrane designed for under floor insulation applications. The low emissivity foil surface provides highly effective reflective insulation while the structure fibre glass reinforcing grid provides superb tear resistance during the application process.
  • Single sided foil for laying directly over a solid floor.
  • Double sided foil for joisted floor applications.

 

 

 

Timber Floor Application
MFoil Double is a corrosion resistant coated highly reflective double faced foil and offers increased insulation levels and reduces draughts from below the floor.

Performance
MFoil can enhance ‘U’ values in new build or refurbished building projects to meet or surpass Building Regulations / Standards, in a quick clean and easy application.
Concrete Floor Application

Concrete Floor Application
MFoil Single is a corrosion resistant coated highly reflective single faced foil and offers increased insulation levels aims to reduce draughts from the floor. MFoil Single is designed as insulation for solid floor areas with a battening system.

Performance
MFoil Single can enhance ‘U’ values in new build or refurbished building projects to meet or surpass Building Regulations, in a fast, clean and easy application.
