How to insulate the floor on the balcony

The balcony in the apartment can turn from the usual place for storing unnecessary things into a cozy and functional room. To do this, you just need to carry out redecoration on the balcony and warm it. In this article we will tell how to warm the floor on the balcony with your own hands, and also for clarity, we will demonstrate the video instruction.

Design features

When working on the balcony weatherization, you should familiarize yourself with the main features of the room design. Usually the base of the floor here is a concrete slab. If it is not covered with insulating material, all efforts to insulate the walls of the balcony will be in vain. The cold will be transmitted from the floor surface of the balcony. Therefore, the most important when working on the insulation of a balcony is floor insulation.

The technology of wall surface insulation on the balcony does not differ from the usual work on wall insulation inside rooms.

Note! For quality insulation of the balcony, it is recommended to use plastic windows, which will well protect this room from the penetration of cold air currents. Also, to preserve heat, you should take care of double-glazed windows.

If it is not possible to install plastic windows, it is necessary to completely close and seal all gaps.

At warming it is worth paying attention and to a balcony ceiling. This is especially true of balconies located on the top floor of the building. The ceiling of the balcony can also serve as a concrete slab. If its surface is damaged, not only moisture and dampness will get inside the room, but also cold air flows, which will reduce the level of heat in the room.

To insulate the floor on the balcony, you should study the process technology, choose the most suitable material and calculate its required amount.

Modern technology development allows the use of various types of materials for insulation. To choose the most appropriate, it is necessary to study the main characteristics and features of each of them.

Types of materials

Warming of the floor on the balcony can be done using the following materials for warming:

Penophole

Данный вид материала является последней разработкой производителей на сегодняшний день. Он представляет собой утеплитель, состоящий из нескольких слоев алюминиевой фольги и полиэтилена, подвергшегося технологии вспенивания. Использование данного материала позволяет получить максимально тонкий слой теплоизоляции, т.к. его толщина не превышает 1 см. Penophole производится в рулонах, что значительно облегчает процедуру его монтажа. Для скрепления частей материала используют алюминиевый скотч. Penophole является не только средством для сохранения тепла в помещении, но и обладает звукоизоляционными и влагонепроницаемыми свойствами.

Mineral wool

It is a glass wool, subjected to extrusion, melting, crushing and cooling. In appearance it resembles ordinary medical cotton, for which it received such a name. This type of material is able to keep and retain heat well. Mineral wool is not damaged by moisture. A distinctive feature is its versatility. Vata can be used for insulation on all types of surfaces. Material is produced in rolls and sheets.

Styrofoam

Достаточно распространенный тип утеплителя. Благодаря своей низкой стоимости является наиболее часто используемым материалом. Styrofoam выпускается в листах. Листы укладываются на поверхность пола. Для наилучшего их скрепления рекомендуется предварительно установить лаги. Между ними следует выложить листы пенопласта. Образующиеся в результате работ щели можно закрыть монтажной пеной.

Penoplex

Relatively new building material. It has high thermal insulation properties. It is made of expanded polystyrene, subjected to foaming. The material is quite simple to install. It has a fairly high cost. Release form - sheets up to 5 cm thick.

Керемзит

It is a porous material. It is made of clay or slate by roasting. Available in gravel, rubble or sand. Expanded clay has good thermal insulation properties. The installation process is quite simple - the material is poured on the floor surface, then the screed is performed. You can set the lags and in between them fill the clay.

Installation of floor heating system

For insulation of the floor on the balcony, you can use any known system "Warm floor". In essence, a warmed balcony is the same room as the whole apartment, so there are no restrictions for choosing a system.

Stages of work

The main stages of the work on floor warming:

1. The choice of material.
2. Surface preparation основания.
3. Laying waterproofing layer.
4. Installation of insulation materials.

The technology of the work may vary depending on the type of materials used. However, in any case, it is recommended to pre-prepare the base.

Surface preparation

Remove the floor covering from the floor surface, remove all items on the balcony. Surface cleaning - it should not be stained with paint, oil, residues of materials. To remove dust and dirt on the balcony, you can use a vacuum cleaner.

If the floor surface is chipped and cracked, it must be sanded and primed. To level the floor on the balcony, you can use the leveling mixture.

If there are large differences in height on the floor surface, they can be removed with the help of tiled glue.

Waterproofing surface

After drying the leveling mixture, you can proceed to waterproofing the floor. If penofol material is used as a heater, it will simultaneously serve as a protection against moisture and a heater.

As a material for waterproofing, you can use a special membrane, film or polyethylene. The prepared material is fixed along the entire perimeter of the balcony base. Bonding places must be glued with construction tape. Also, the resulting joints can be closed with foam.

We use heat-insulating material

To independently make the floor insulation on the balcony, you must follow the following recommendations:

• When insulating with thermal insulation materials, it is recommended to pre-install wooden logs on the surface. The spacing is about 50 cm. The distance from the wall is 5 cm. Laying method is transverse. To prevent the destruction of the material it is pre-treated with an antiseptic substance.
• Between the lags fit insulation material. The height of the laying of insulation materials must match the height of the lag. To achieve this, the material can be laid in several layers.
• The gaps formed as a result of work are closed with the help of polyurethane foam.
• Laying flooring.

System "warm floor" on the basis of the heating cable

After preparing the base surface and installing the waterproofing layer, you can proceed to the installation of the heating system. It is carried out in several stages:

1. Attaching insulating plates with special glue.
2. Fastening on the surface of the welded metal mesh. You can also use glue for this.
3. Cabling system. Step - 10 cm.
4. Fastening the tape on a metal grid with self-tapping screws.
5. Install a temperature sensor.
6. Filling the system with cement screed. Its thickness can reach 5 cm.

The heating system is ready to work after the complete drying of the screed.
