The substrate under floor heating - species and laying technology

heat warms the floor in the recently de facto standard construction of heating systems in apartment buildings and private houses.The use of the heated floor system allows you to create the most comfortable indoor environment.

heating systems warm floors can have different characteristics and operate on different principles.When designing a heated warm floors can use any type of finishing flooring thus Heated Heated floor can be installed in any purpose: a sleeping infant or in a kitchen or bathroom.

very important element in the design of the floor heating is its substrate.With it extremely increases the efficiency of the heating circuit, whether it is an electric heating cable, infrared film or pipe with liquid coolant.

Key Features

1. In order to understand exactly what type of support you need - you need to know why you need a substrate in the heated floor systems.
2. So podolzhka must first possess excellent properties of thermal insulation and waterproofing.It should increase the efficiency of the heating system.
3. important property of the substrate is its ability to reflect heat rays.
4. substrate to withstand temperature changes, working in close contact with the heating elements.
5. substrate should also not miss the water vapor formed during heating.
6. excellent additional properties of the substrate will be isolation sound.

quality substrate is easy to install, has a high resistance to deformation and is environmentally safe.

This photograph shows a roll substrate under floor heating, which is equipped with an additional reflective layer with a characteristic metallic luster.

Features substrate mounting a laminate plank on floor heating

One of the most sensitive materials finishing flooring is a laminated board.It is made of wood, and therefore it has all the characteristics of a wooden board, which has both its advantages and disadvantages.When laying laminate flooring on floor heating - use of the substrate is indispensable.

addition to preventing damage due to heat laminate board - under the laminate substrate also serves as a sound insulator, preventing the floor finish to be too "loud."Minimum substrate thickness of the laminate floor board on the heated floor should be at least 3 millimeters.In the operation of such substrate is compressed more, without losing its insulating properties.

stepwise algorithm for placing the substrate under a laminate floor board on the heated substrate

Consider stacking procedure of polyethylene foam under laminate plank on the heated floor.

First of all, you need to remove the workspace.To do this, you can use an ordinary broom or vacuum cleaner.

laid spread out then roll substrate on the cleaned surface.

spread out to fix the substrate can be a two-way tape, and then proceed directly to the laying of laminate boards.

substrate on heated floors with liquid coolant

If any structure is heated flooring substrate is to perform the functions of increasing the heat transfer of the heating elements.In that case, if you are using a heat transfer fluid - ie construct a warm water floor - your substrate may additionally serve as the surface for waterproofing.

When installing water heated floor you can use such a substrate, which further will be the basis for the coolant system piping installation.This substrate has a special projections, between which is installed pipeline system.

Typically, this substrate is made of foam.One type of substrate and a warm water floor shown in photos.

We must remember that a good substrate will be based on the foil.In case the substrate is not your foil layer, it makes sense to put on the floor separate thin foil material, and then the insulating substrate.

In addition, when installing the water warm sex and you may need additional installation wiring reinforcing mesh, which will serve as a basis for fixing the pipe system.

In this case the substrate under a warm water floor will look like a kind of "sandwich" consisting of a foil layer, a layer of thermal insulation and a layer of reinforced mounting grid.

variant of such a substrate is shown in Fig.

substrate under a warm electric floor

substrate under a warm electric floor in its design resembles a substrate under floor heating with heat transfer fluid.However, in this case, you may not need additional surface waterproofing.

In this case, on the leveled and pre-cleaned surface of the base substrate layer stacks, which may consist of a composite material including a foil layer.Next, on the substrate mounting surface of the tape is attached, to which is attached a heating cable clamps.

substrate Laying a heated infrared film floor

when installing heated infrared film floor is also necessaryuse a substrate with insulating and reflective properties.In this case, the substrate film is placed directly under the infrared heated floor.In addition to the roll substrate can be used as heat insulation fiber board and magnesite plate.

If your substrate is not foil layer, you can also design a "sandwich" of heat insulation and foil.

good choice as a substrate under a warm film floor can be an insulator penofol.

It has a reinforced structure with air sinuses, have excellent insulating properties and a layer of foil, which significantly reduces heat loss in the room.

substrate with foiled layer holds up to 97 percent of heat rays, which greatly improves the efficiency of your heating system.

Important nuances

When installing floor heating on the substrate for any type of topcoat, you need to remember a few important nuances.

1. First of all, note that the reflective foil substrate side should be facing up.
2. substrate must be laid butt.To prevent heat loss at the joints, the substrate strip is best to combine metallic tape.It will also serve as an additional barrier to moisture and steam.
3. heating elements, whether it is electric cable, infrared film or tubing with a liquid coolant must be mounted on top of the coating that reflects heat rays.
