Concrete Ground Floor Insulation

Ground floors are usually constructed as either solid ground floors or suspended ground floors.

Concrete ground floor insulation.

However i think by far the best option is one that offers complete insulation from the ground. In a solid or ground bearing because it is continuously supported by the ground across its whole area concrete floor the choice of insulation position relative to the concrete slab is commonly linked to the building s heating system. The panels can be applied to every surface from floors to walls to ceilings. The insulation is installed on the concrete which is directly on top of the ground.

Typically the insulation would be situated below the slab and below the damp proof membrane for heavy duty use whilst normal domestic buildings would have a. Ecotherm insulation has excellent compressive strength which is advantageous when insulating a floor. Insofast is a diyers dream a simple way to install insulation needing only a hand saw utility knife and caulking gun. How to insulate a concrete floor using ecotec floorfoam.

This approach avoids the heat sink of having concrete directly under the floor as described in ground bearing floors under slab. Whilst heat rises it is also very important to insulate the floors as part of the total building envelope. Insofast s insulation panels provide an easy way to insulate a cold concrete floor. Where concrete floor slabs have replaced earlier floors they may include a damp proof membrane dpm but unless laid comparatively recently they might not be well insulated.

Design considerations such as existing ground conditions the presence of radon gas or methane gas and the intended use of the building are among the factors that will dictate the choice of ground floor and also the insulation used within them. This building method works well with underfloor heating. Where floors do include a dpm and show no evidence of moisture laying a floating wooden floor or thermal underlay with a carpet on top is often the easiest means of. Floorfoam is a 4mm dense foam foil membrane to be used under carpets laminate.

Then screed is installed above the insulation. Ecotec floorfoam has a high reflective foil either side of the foam membrane. If your concrete floor is for industrial or heavy duty applications then any insulation you use needs to have a high compressive strength to take the weight of whatever is above. These foils will help retain the heat and stop the cold rising into your home.

Ground bearing concrete floors. Bulletin number 552 edge insulation of concrete floor slabs from branz outlines the accepted solutions for installing edge insulation or a thermal break between the slab and the perimeter wall. Kooltherm k3 floorboard is a super high performance fibre free rigid thermoset closed cell phenolic insulation for solid concrete ground based floors.
