The capillary tube mats are integrated into the screed. First of all, an insulation is laid on the unfinished floor. A system insulation with moisture barrier is recommended. The capillary tube mats are laid and fixed on the insulation. The screed is then applied. The desired floor covering, such as parquet, tiles or carpet, is applied to the finished screed. This flooring material should be suitable for floor heating systems.
The small distance between the capillaries (20 mm), ensures a homogeneous heat distribution across the floor. At low excess temperature, the heat is emitted to a large extent via radiation, partly also via convection.
Capillary tube mat
The Clina capillary tube mat OPTIMAT SB 20.00 is recommended for this design.
Length & Width
The capillary tube mats are custom-made in length and width for each room at Clina. On site, the mat distributor pipes are connected by means of heating element socket welding.
This is a secure, non-detachable connection.
Mat distributor pipes and supply lines are placed in the floor, i.e. in the screed or in the insulation (in recesses/ slots). The capillary tube mats, welded together to a hydraulic circuit, are connected to the supply and return lines and to a centrally located manifold.
The capillary tube mats are rolled out on the insulation and fixed with suitable fixing material, such as plastic nails or U-clips.
All customary screeds are suitable. They are applied using the pumping method, for example. The corresponding minimum layer thickness of the respective screed must be respected.
The system can be regulated room-by-room.
Fields of application
Suitable for all buildings, such as residential buildings, office buildings, hotels etc., whether new construction or renovation.

recommended capillary tube mat
The OPTIMAT SB 20.00 consists of 2 round mat distributor pipes (20 x 2,0 mm) and capillary tubes (4,3 x 0,8 mm).
The constant distance between the capillary tubes (centre-to-centre distance) is 20 mm and is guaranteed by the omega ribbons.
- high mechanical resilience
- low pressure loss
- good venting
High performance - high dynamics
Thanks to the small distance of the capillary tubes of 20 mm, the floor is heated homogeneously. As a result of this and due to the position of the capillary tube mats close to the surface a high heat output at low system temperatures can be achieved. This results in extremely short warm-up times. Compared to conventional underfloor heating systems (e.g. single-pipe systems), Clina underfloor heating only requires approx. 1/4 of the warm-up time.
Environmentally friendly and energy efficient
Very low system temperatures and extremely short warm-up times save money and protect the environment.
Ideal for renovations
If mat distributor pipes and supply lines can be accommodated in recesses or slots in the insulation layer, then the application of the screed minimum thickness is sufficient.
No bulky radiators, therefore more architectural design options, such as floor-to-ceiling windows. You also have more options when it comes to the interior design.
Ideal for people with asthma or dust allergies
Due to the low level of convection you have no stirring up of dust.
Smooth, energy-efficient temperature control
Due to the homogeneous heat distribution it is possible to work with a low system temperature. This has a positive impact on the feeling of comfort and reduces heating energy consumption. The perceived temperature is around approx. 2–3 °C higher than the actual room temperature.
