Tack/Noppen
Vloerverwarming met tackernieten of noppenplaten bovenop de draagvloer
Tacking underfloor heating pipes is done with plastic tacker staples that fix the pipe to insulation boards. This method is applied when a sand-cement screed still needs to be poured and there is no or insufficient possibility to insulate from below.
Pouring the screed is carried out by a third party. The screed sits 5–7 cm above the insulation boards. Per centimetre, a drying time of one week applies — so expect 5 to 7 weeks during which the underfloor heating must remain switched off.
Stud plates offer an alternative solution for insulating on top of the concrete floor. Above the underfloor heating pipe, at the height of the studs, a sand-cement screed of at least 3 cm still needs to be poured. The thickness of stud plates varies from 28 to 53 mm, bringing the minimum build-up height to 58 mm. The drying time for that is 3 weeks.
As with the steel mesh method, the pipes end up deep within the screed. As a result it takes longer for the heating to reach temperature, but the mass of the screed acts as a heat battery — it also stays warm longer. The heat source needs to cycle less often, which is favourable for energy consumption.
