Removal of the existing floor

The installation of the Fermacell / Estrich / Knauf or Gypsum fiberboard subfloor is used if the underfloor heating cannot be milled into the existing screed. this usually applies if a house 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 fix it before installing the Fermacell / Estrich / Knauf or Gypsum fiber board subfloor.

Existing radiators and convector wells

When installing underfloor heating, existing radiators and convector wells can be closed off and removed. The disconnection and removal of the existing radiators and convector wells must be carried out by a plumber. With the preparation of the floor, Uipkes can cover the old convector wells so that a flat, solid surface is created for the installation of the Fermacell / Estrich / Knauf / Gypsum fiber board subfloor.

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

Placing the Fermacell/ Estrich/ Knauf/ Gypsum fiberboard subfloor

Nadat de bestaande afwerkvloer verwijderd is, nagelopen op defecten, plaatsen we de Fermacell/ Estrich/ Knauf/ Gipsvezelplaten ondervloer. De platen hebben een afmeting van ca 500 mm breed en 1500 mm lang en hebben een overlappende onder en oversteek waar de lijm op aangebracht wordt.

Langs de wanden worden randstroken geplaatst om geluid doorgifte tegen te gaan. De Fermacell/ Estrich/ Knauf/ Gipsvezelplaten worden over elkaar geplaatst, voor een strakke aansluiting en vastgezet met schroeven om een goede verbinding van de lijm te realiseren. De platen worden steensgewijs geplaatst voor een juiste spanningsverdeling voor de houten vloer. Nadat de lijm uitgehard is, dienen de schroeven verwijderd te worden, zodat deze geen schade kunnen geven aan de freesmachine.

After the existing finishing floor has been removed and checked for defects, we place the Fermacell/ Estrich/ Knauf/ Gypsum fiberboard subfloor. The plates have a size of 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 connection and secured with screws to achieve a good bond of the adhesive. The plates are placed in bricks for a correct stress distribution for the wooden floor. After the glue has cured, the screws must be removed so that they cannot 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 10-12.5 cm, milled center to center. The milling is carried out as dust-free as possible due to the special dust extraction.

The plastic pipes with a width of approximately 14 mm are placed in these slots. The pipes fit exactly in the slots and therefore they are firmly fixed. After the pipes have been placed, they are connected to the distribution station, which is placed at a central location. Usually this is a stair cupboard or another central point.

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

When the system has been tested, we ensure that the pipes are fixed in the slots, so that the pipes remain deep in the trench when they are filled. 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 is given a flat finish, in preparation for the new wooden floor.

How many groups are needed for the underfloor heating?

To generate sufficient capacity, you must take into account about 8-10m2 per required group for installing the underfloor heating. With an area of approximately 50m2, this means that approximately 5 groups are needed.

Total Cost Indication

For the cost indication we assume an average surface of 50m2.

For the removal and disposal of the existing finishing floor, the costs are from €15,-/m2 including VAT. (depending on the type of floor).
For checking the screed, installing the Fermacell/ Estrich/ Knauf/ Gypsum fiber board subfloor and edge strips, an investment of approximately €60/m2 including VAT must be taken into account. Based on 50m2, this amounts to an investment of approximately €3000,- incl VAT
The investment for milling in the underfloor heating, installing the pipes, placing the distribution station, lubricating the trenches and connecting the pipes to the distribution station amounts to an investment of approximately €3150 for a space of 50m2. - incl. VAT.

Time needed for all activities

Despite the fact that the work is extensive, the lead time is not too bad. Based on our example of 50m2, a complete care of all activities from removal of the existing floor, up to and including the refitting of the furniture, would have a lead time of approximately 7-21 days. (provided all preparatory work has been carried out)

You can use the following distribution:

Removing and disposing of the existing floor, placing the Fermacell/ Estrich/ Knauf/ Gypsum fiber board subfloor and edge strips; approx. 1 day.
Routing the underfloor heating, placing the pipes, hanging the distribution station, connecting the pipes to the distribution station and lubricating the pipes, approx. 1 day. (when all other preparatory work has been carried out)
Installing a new wooden floor, including color finish: approx. 3 days.
Drying of the color treatment: approx. 2 days.

Points of Attention

Space should be free of stuff.
After removing the existing floor, check the screed for broken or creaky parts.
Existing radiators and convector ducts must be disconnected and removed by a plumber (preparatory work).
When installing the Fermacell/ Estrich/ Knauf/ Gypsum fiber board subfloor, screws are used to get a good bond for the adhesive. These screws must be removed before milling to avoid damage to the milling machine.
At the position of the distribution station, a supply and discharge of the heating boiler must be prepared. There should also be a power point at this location.
Before the wooden floor can be placed on underfloor heating, the underfloor heating must first be tested.
