Insulation – Underfloor Heating – Screed Retrofit

 

With most screeds being installed at 75mm, there is an opportunity to install insulation and underfloor heating in the same depth.

Underfloor heating has become very popular now resulting in them extremely cost-effective to install. When you consider the lower operating costs there are long-term savings to be gained.

Screed historically have always been installed at 75mm to give the required strength but liquid screed is far superior allowing you to reduce the depth.

Liquid screeds recommended depth is 35-50mm thus giving you up to 40mm insulation space.

 

Thin Underfloor Heating Systems

 

There are many thin underfloor heating products available including electric.

They are very expensive and do not allow for the right amount if floor insulation below.

Because there is no screed on top, there is no Thermal mass to heat, thus giving large fluctuations in temperature.

 

We recommend installing

 

  • Remove existing sand and cement screed 
  • Install 1000gu DPM 
  • Install 40mm Kingspan Kooltherm K103 to achieve Ground floor = 0.25W/m²
  • To achieve a lower U Value install a Vacuum Insulated Panel 
  • Thin gauge slip membrane
  • 16mm Wet Underfloor Heating system
  • 35mm Liquid screed Flow HTC

 

The benefits of Underfloor Heating

 

  • All year round Comfort
  • Heat is distributed evenly and consistently around each room
  • Underfloor heating is more hygienic

  • Less wastage and reduced heating costs
  • Radiators are not required leaving more design space
