1. Thermal insulation for floors with Isobet
The thermal insulation of the floors will consist of a monolithic insulating ‘Isobet’ mortar layer, composed from a mixture of pure recycled EPS granules of 1 to 4 mm, and vermiculite with cement as a binding agent. The additional additives improve the thermal insulating value, homogeneity and mechanical properties.
After having been cleaned, the support floor is moistened and brushed with cement. If there exists the danger of rising damp, a polyethylene foil, the joints of which generously overlap, is placed onto the supporting floor.
‘Isobet’ is supplied in bags (approx. 130 litres) clearly labelled ‘Isobet’ and provided with multi-lingual directions for use. 25 kg of cement and water is added to the bag of ‘Isobet’ on site. The mixture is intensively mixed by means of a screed machine or large concrete mixer. The insulating mortar is always mixed per entire bag. The insulating mortar can also be mixed, supplied and pumped by means of a Mega-MaxiMixer.
The insulating mortar is spread to a thickness of ... cm (4 to 10 cm) in order to obtain a U value of ... W/m²K (please refer to table). This layer fully covers all pipes of electricity, heating and water supply.
After drying during 3 to 4 days the top floor or tiling is placed in a sand-cement bed.
The described insulation system carries a valid technical BUtgb (ATG 01/2450) approval.
Properties of Isobet :
- thermal conductivity : 0.075 W/mK (dry) – 0.085 W/mK (calculation value)
- compression strength: > 0.3 N/mm²
- weight by volume: + 240 kg/m³ (dry)
- fire resistance: A1 (NBN S 21-203) - MO (NF P 92-507)
- point load Ø 80 mm: > 550 kPa (NBN AND 12430)
- fatigue (15000 cycles up to 6 kN/m²) < 0.04 mm (WTCB TV 189 §8.2.3.)
Thermal performance of an average floor construction with Isobet:
Thickness Isobet | ± U-value floor |
4 cm | 1,18 W/m²K |
2. Thermal insulation for floors with Styrobet
The thermal insulation of the floors will consist of a monolithic insulating ‘Isobet’ mortar layer, composed from a mixture of pure recycled EPS granules of 1 to 4 mm, and vermiculite with cement as a binding agent. The additional additives improve the thermal insulating value, homogeneity and mechanical properties.
After having been cleaned, the support floor is moistened and brushed with cement. If there exists the danger of rising damp, a polyethylene foil, the joints of which generously overlap, is placed onto the supporting floor.
‘Styrobet’ is supplied in bags (approx. 62 litres) clearly labelled ‘Styrobet’ and provided with multi-lingual directions for use. Only water is added to the bag of ‘Styrobet’ on site. The mixture is intensively mixed by means of a screed machine, a concrete mixer or a hand mixer. The insulating mortar is always mixed per entire bag. The insulating mortar can also be mixed, supplied and pumped by means of a Mega-MaxiMixer.
The insulating mortar is spread to a thickness of ... cm (4 to 10 cm) in order to obtain a U value of ... W/m²K (please refer to table). This layer fully covers all pipes of electricity, heating and water supply.
After drying during 3 to 4 days the top floor or tiling is placed in a sand-cement bed.
The described insulation system carries a valid technical BUtgb (ATG 01/2450) approval.
Properties of Styrobet :
- thermal conductivity : 0.093 W/mK (dry) – 0.10 W/mK (calculation value)
- compression strength: > 0.5 N/mm²
- weight by volume: + 240 kg/m³ (dry)
- fire resistance: A1 (NBN S 21-203) - MO (NF P 92-507)
- point load Ø 80 mm: > 550 kPa (NBN AND 12430)
- fatigue (15000 cycles up to 6 kN/m²) < 0.04 mm (WTCB TV 189 §8.2.3.)
Thermal performance of an average floor construction with Styrobet:
Thickness Styrobet | ± U-value floor |
