There will be a damp proof membrane under the insulation and possibly a second membrane on top depending on the type of screed.
Ground floor insulation boards.
Eps can be a cost effective alternative to pir for floor insulation and the same thermal performance can be achieved with increased thickness.
Where damp is evident ensure external ground levels are lower than the floor and drains and gullies are not.
R 3 2 polyisocyanurate rigid foam insulation board r matte plus 3 thermasheath 3 is rigid foam r matte plus 3 thermasheath 3 is rigid foam plastic thermal insulation board.
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.
We also have insulation boards suitable for more specialist flooring applications for example heavy duty floor insulation and insulation for cellar and basement floors.
Foam board insulation is easy to use and is a great diy way to add some insulation.
Insulation is laid on the concrete and covered with a screed.
Most modern homes have a solid floor for example.
Rockwool rigid stone wool boards used as a continuous layer of insulation under a concrete slab can provide the thermal efficiency and mechanical properties required as an alternative to rigid foam.
We have a wide range of floor insulation boards including solid ground floor insulation suspended floor insulation and soffit insulation.
Alternatively foil faced foam or woodfibre insulation boards can be fitted between the joists supported on timber battens.
Solid ground floor insulation solutions kooltherm k3 floorboard kooltherm k3 is a premium performance rigid thermoset phenolic insulation board for use with solid concrete suspended ground floors.
It s made of environmentally sound closed cell polyisocyanurate foam bonded to a durable white matte non glare aluminum facer and a reflective reinforced aluminum facer.
Ground floors are usually constructed as either solid ground floors or suspended ground floors.
Insulating a solid floor.
Insulating a solid ground floor below the ground bearing concrete slab can be done using either pir insulation boards or eps insulation boards.
It comes in standard size 4 8 sheets and smaller sizes in many different thicknesses from 1 4 inch to 2 inches.
