FLOORMATE™ 700-AP closed-cell polystyrene foam thermal insulation, with its excellent thermal insulation capability, high compressive strength and resistance to moisture, can be safely used in locations where good thermal insulation capability is only one of many complex requirements. It is suitable for load-bearing industrial floors, base slabs or high-load rooftop car parks.
FLOORMATE™ extruded polystyrene thermal insulation can be used in a wide range of applications, thanks to its beneficial properties as a result of its closed-cell material structure:
- permanently high thermal insulation level
- negligible moisture uptake
- high strength and rigidity
- dimensional stability
- resistance to rot and deterioration
- simple and quick installation with only a small amount of waste.
FLOORMATE™ 700-AP thermal insulation is manufactured by extrusion production procedure, resulting in a homogeneous, closed-cell material structure, a smooth surface skin (extrusion skin) and many favourable material properties:
- permanently high thermal insulation performance
- water and frost resistance
- high compressive strength
- high flexible rigidity
- high vapor diffusion resistance
FLOORMATE™ 700-AP thermal insulation can be applied either above or below the reinforced concrete slab, even if laid down directly onto a compacted gravel bed. In this case the framework of the reinforced concrete floor structure can be assembled on top of the thermal insulation. The insulation of the building against soil moisture can also be prepared here. Using this method can save a layer of blind concrete, reducing costs.
- built-in insulation-protection
- resistance to rot and deterioration
- high insulation performance over decades
- high moisture resistance
- low compression
- high E-modulus
- simple structural design and workability
- resistance to freeze-thaw cycles
To determine the load-bearing capacity of domestic floor structures that incorporate a thermal insulation layer for permanent loads, compressive strength values for permanent load must be used.
To plan the reinforcement steel requirements of floor slab used as a load-distribution structure over the thermal insulation layer, please consult a structural engineer.
INSTALLATION OF FLOORMATE™ 700-AP
Onto a concrete surface
The lightweight, easy-to-handle FLOORMATE™ boards can be laid down simply and quickly without adhesives, using the ship lapped boards.
The placement of a PE film separating and sliding layer between the thermal insulation and the concrete screed layers is recommended.
In slabs between levels, impact sound insulation must be resolved separately.
Onto a compacted gravel layer
FLOORMATE™ thermal insulation boards are to be laid down in an offset bond, directly onto the compacted gravel layer of a thin blinding layer of concrete, with screed levelling if necessary. The thermal insulation boards can be laid down simply and quickly in any weather conditions. The boards can be cut to size by a handsaw or hot wire cutter. The cut surfaces can be accurately fitted together.
Thanks to their high strength, the thermal insulation boards will not be penetrated by metal reinforcement spacers, so the homogeneity of the concrete layer will be ensured everywhere. During the fitting work, it is possible to walk on the thermal insulation or use load-distribution planks or flooring boards on the area that has been already fitted.
Where the thermal insulation boards are installed above the waterproofing layer, they will also act as a mechanical protective layer during construction, which is particularly useful during rebar installation.
The permanent application temperature of FLOORMATE™ products is. 75°C maximum. At higher temperatures, the boards will start to soften and suffer permanent deformation.
FLOORMATE™ products contain an ecologically safe flame-retardant additive, as a result of which they will be self-extinguishing under their ignition temperature. They will, however, burn if exposed to an intensive ignition source.
FLOORMATE™ products are resistant to commonly used construction materials which don’t contain solvents or softeners (bituminous components without solvents, water-based wall protecting materials, lime, cement, masonry mortars and plasters, anhydrous gypsum etc.).
Certain organic materials, such as solvent-based wood preservatives, paint additives, solvents (acetone, ethyl acetate, kerosene, gasoline etc.) will cause softening, shrinking and damage to the material.
For gluing, solvent-free adhesives must be used. Follow the supplier’s guidance.
FLOORMATE™ products should not be exposed to permanent intensive direct sunlight.
