Uipkes Wood Flooring can completely take care of the actions of removing the 'old' floor, installing the Fermacell / Estrich / Knauf / Gypsum fiber boards subfloor, installing the underfloor heating and installing the beautiful new wooden floor that you have bought with us. You can also have underfloor heating installed as a separate service from us.

We can take care of the organization of all work and therefore completely relieve you of your worries. From the removal of the existing floor until the moment that the furniture can be placed back on the new wooden floor.

Removal of the existing floor

The installation of the Fermacell / Estrich / Knauf or Gypsum Fiber Board subfloor is used if the underfloor heating cannot be milled into the existing screed floor. This usually concerns if a home has a wooden screed floor.

We will professionally remove and dispose of the existing finishing floor such as PVC, laminate or existing wooden floor. We will check the screed for broken or creaking parts and secure these before installing the Fermacell / Estrich / Knauf or Gypsum Fiber Board subfloor.

Existing radiators and convector ducts

When installing underfloor heating , existing radiators and convector ducts can be closed off and removed. Disconnecting and removing existing radiators and convector ducts must be carried out by a plumber. Uipkes can cover the old convector pits during the preparation of the floor, creating a flat, solid surface for installing the Fermacell/ Estrich/ Knauf/ Gypsum fiber boards subfloor.

If necessary, Uipkes wooden floors can supply a plumber who will take care of this work.

Installing the Fermacell / Estrich / Knauf / Plasterboard subfloor

After the existing finishing floor has been removed and checked for defects, we install the Fermacell/ Estrich/ Knauf/ Gypsum fiber boards subfloor. The plates measure approximately 500 mm wide and 1500 mm long and have an overlapping bottom and overhang on which the glue is applied.

Edge strips are placed along the walls to prevent sound transmission. The Fermacell/ Estrich/ Knauf/ Gypsum fiber boards are placed on top of each other for a tight fit and secured with screws to ensure a good bond of the glue. The plates are placed brick by block for correct stress distribution for the wooden floor. After the glue has hardened, the screws must be removed so that they do not damage the milling machine.

Milling the slots and installing the pipes

Based on a Fermacell/ Estrich/ Knauf/ Gypsum fiberboard subfloor, we mill the slots with a special floor milling machine to a depth of approximately 17 mm. The distance between the slots is milled 10-12.5 cm center to center. Milling is carried out as dust-free as possible thanks to the special dust extraction.

Plastic pipes with a width of approximately 14mm are placed in these slots. The pipes fit exactly into the slots and are therefore firmly secured. After the pipes have been installed, they are connected to the distribution station, which is placed in a central location. This is usually a stair cupboard or another central point.

If there is no supply and discharge from the boiler, a plumber must prepare this. There must also be a power point at this location. If necessary, Uipkes wooden floors can supply a plumber who will take care of this work. The distribution station can then be connected to the heating boiler supply.

Once the system has been tested, we ensure that the pipes are fixed in the bends, so that the pipes remain deep in the trench during filling. The slots are filled with an epoxy, diluted with the grinding dust or a special flexible filling mortar, which can expand and contract with the heat of the pipes. This is spread over the floor with a trowel, so that the filling is evenly distributed in the slots and the floor. gets a flat finish in preparation for the new wooden floor.

How many groups are needed for underfloor heating ?

For the number of groups, the rule of thumb of 1 group per 8-9 m2 (as main heating) can be used. The pipes are placed at a distance of approximately 10 cm from center to center.
