How to insulate a cold garage

In order for a garage to serve its owner for a long time, like the car that sits in it, its structure needs to be strengthened.Internal and external insulation will not only protect the car and walls from condensation and its destructive effects, but will also allow you to maintain the desired temperature inside the room. This requires materials that can withstand temperature changes and bad weather. The LOGICPIR thermal plate from TECHNONICOL will cope with the task. You can even install thermal insulation materials yourself, without resorting to the services of a specialist.

Why insulate a garage

A garage is a non-residential premises intended for storing a car, tools and carrying out repairs (if necessary). It is built from bricks, cinder blocks (sometimes metal). The thickness of the walls is usually in the range of 120-250 mm. They can protect from wind and precipitation, but not from exposure to low temperatures.Therefore, the garage must be insulated.

What temperature should the garage be?

Car owners mistakenly believe that the temperature in the garage should be comfortable for a person. But the optimal parameters are different:

• in winter the temperature should not fall below +5 °C;
• at any time of the year, the room temperature should not exceed +20 °C.

The smaller the difference in internal and external temperatures, the lower the likelihood that condensation will form on the car and other surfaces, which causes corrosion.

Why does condensation form in the garage?

If the garage space is not properly insulated and sufficient ventilation is not provided, drops of condensation will inevitably appear. For example, a person drives a car into a garage, closes it and leaves. The engine and exhaust pipe are still very hot, and little by little they begin to warm up the icy air in the room. But the engine cools down quickly, and condensation forms on its cooled surface. Which will lead to corrosion.

But condensation can also form on the ceiling, walls and gates. If the garage is metal, it will begin to rust along with the car. If it is built of brick or cinder blocks, mold and mildew will develop on their surface.

To avoid all these problems, you need to take care of high-quality insulation. And the best option for this is the LOGICPIR thermal plate from TECHNONICOL.

Types of insulation

You can insulate a garage from the outside and inside. Each method has its own advantages and disadvantages that need to be taken into account before purchasing materials and starting work.

Internal insulation

This option is suitable if it is not possible to insulate the outside of the structure (for example, when the building is located between 2 others), or it is impossible to remove shelves inside the room. For internal insulation, materials with a small thickness are ideal, which will not “eat up” the already small area. For example, the LOGICPIR thermal plate from TECHNONICOL.

The only negative that may appear if you choose low-quality materials for thermal insulation or violate the technology is a shift in the freezing point inside the garage, to the place of maximum contact of the insulation and the wall. As a result, this may cause destruction of the materials from which the walls are built.

External insulation

An option that is often preferred by craftsmen, based on personal experience. It has its advantages:

• the likelihood of walls freezing is reduced;
• no need to dismantle shelves for insulation;
• there will be no favorable environment for the development of pathogenic microbes and fungi;
• fumes from insulation materials will not adversely affect humans.

Where is it better to insulate - outside or inside?

Internal insulation of the garage is a priority option. This method has more advantages. It is especially worth considering the fact that the internal thermal insulation will not be affected by the external environment, which means it will retain its original characteristics longer.

But do not forget that some types of insulation can emit harmful substances during operation. But not LOGICPIR from TECHNONICOL. The plates are completely safe for human health, which has been proven at the Institute of Solution Chemistry of the Russian Academy of Sciences.

Requirements for garage insulation

Before using LOGICPIR slabs from TECHNONICOL for insulation, you should take into account a number of important nuances regarding the work:

• the plates must be placed in such a way that they do not block the ventilation openings;
• thermal insulation boards or other thermal protection should cover not only the walls, but also the gates, garage floor, ceiling;
• Before carrying out insulation work, you should read section 6 of SNiPa-89. It describes in detail the requirements for premises intended for storing vehicles of any category. If this is a personal garage, then there is no need to strictly adhere to them, but the standards can help in resolving some issues.

Design features of the garage that are taken into account when laying thermal insulation

The first feature is that the garage has thin walls and a roof. This is a non-residential building, therefore the maximum thickness of a wall made of cinder blocks or bricks is up to 25 cm. If the garage is metal, then this figure can reach only a few centimeters. Such walls are not able to provide the necessary thermal insulation, therefore they require high-quality insulation not with outdated, but with modern materials, such as LOGICPIR from TECHNONICOL.

When choosing a material for insulation, you need to strive to ensure that after its installation inside the garage in the cold season, the temperature does not drop below 0. If the installation work is carried out correctly, the thermal insulation will provide the desired effect: in winter it will not let heat out, and in summer it will prevent overheating premises.

Thermal insulation characteristics for garage

The first task facing the garage owner is to select the material for the thermal insulation layer. It must have the following characteristics:

• minimal thermal conductivity;
• ease of installation;
• resistance to moisture, mold and mildew;
• high fire protection characteristics;
• light weight and thin thickness.

Types of insulation

A garage is a non-residential space, and you can save a little on thermal insulation, but not at the expense of quality. It is also worth evaluating all the advantages and disadvantages of different insulation materials in order to choose the best one.

Mineral wool

Its basis is basalt fibers. The material is produced in accordance with the regulatory document GOST 4640-2011. For thermal insulation in Russia it is used more often than other options, since its price is quite low.

Mineral wool is sold in the form of rolls or hard mats. For insulation of residential and non-residential buildings, the latter option is more preferable, since with its help you can carry out the installation yourself, without the help of professionals.

Glass wool

The material is made from woven threads of inorganic glass, taking into account the requirements of the regulatory and technical document GOST 19170-2001. Glass wool goes on sale in 2 forms - slabs and rolls.

Styrofoam

Polystyrene foam is often used for insulation, as it has high sound insulation properties. It is produced in two forms - foamed and extruded. The latter is more rigid and dense, so it can be used to insulate not only walls, but also floors, ceilings, and garage doors.

Expanded polystyrene

This is a subtype of polystyrene foam, but with higher thermal insulation characteristics. Produced in accordance with GOST 15588-2014. The main component of the insulation is styrene. Foaming agents are also added.

The structure of expanded polystyrene is dense, so it is not only convenient to work with, but it also provides a reliable connecting system, which reduces the likelihood of the formation of cold bridges.

Polyurethane foams and their relatives

A material that garage owners value more than others, as it is resistant to the external environment and pathogenic microorganisms. They produce liquid and rigid polyurethane foam. The first option expands when applied, covering all voids and cracks. It also adheres well to the walls, which reduces the possibility of condensation to zero.

Today, rigid modified polyurethane foam with PIR foil lining, which is produced in accordance with GOST R 56590-2015 (EN 13165-2012), is more popular. The foil layer protects the enclosing structure from steam penetration and overheating. It also reflects heat into the room.

LOGICPIR thermal plate is one of the best materials for insulating residential and non-residential premises built from any materials. PIR is an improved modification of polyurethane. It has high technical and operational characteristics, which allows it to effectively reflect heat and not allow moisture to pass through to prevent the formation of condensation. In a room insulated with LOGICPIR, an optimal microclimate is maintained for a long time.

Warm plaster

Warm plaster is a new product on the building materials market.The material consists of components with a low thermal conductivity coefficient (pumice, expanded clay, expanded polystyrene and others). Cement or gypsum acts as a binding element.

Warm plaster can be installed on any surface - aerated concrete, brick, drywall.

Warming paint

The basis of the material is synthetic polymers and acrylic elements. This tandem provides the insulating paint with high thermal insulation properties. Externally, the material is similar to ordinary paint. But only 1 mm of layer will be equal to 5 cm of other insulation.

Comparative table of popular insulation materials by thermal conductivity

To choose a material for insulating a garage, it is better to study the thermal insulation properties of each.

Garage insulation LOGICPIR from TECHNONICOL

The best option for reliable thermal insulation of a garage is LOGICPIR from TECHNONICOL. PIR is a new generation material based on a polymer related to polyurethanes. In terms of its technical and operational characteristics, it surpasses all other insulation materials on the market.

Over 95% of PIR are closed rigid cells. They are formed as a result of the reaction of a polyol and isocyanate. The process occurs at high temperatures, which allows the excess isocyanate to react with itself, thereby promoting the formation of stronger bonds.

Installation of LOGICPIR from TECHNONICOL can be carried out at any time of the year. The plates have a foil lining, which provides them with shielding properties.

Characteristics

Due to their characteristics, LOGICPIR slabs from TECHNONICOL are suitable for installation in wet and dry rooms. And the shape of the edge reduces the likelihood of gaps appearing during installation. The service life of the insulation is more than 50 years.

Installation instructions for LOGICPIR from TECHNONICOL

To ensure thermal insulation of the garage, LOGICPIR from TECHNONICOL is used to insulate all surfaces - floors, ceilings, walls and even gates. But here it is important to strictly follow the technology so as not to miss anything important.

Necessary tools and materials

At each stage of thermal insulation of a garage, a different set of tools is used. Therefore, they all need to be assembled before installation work.

Set of tools for surface preparation:

• a stiff brush for cleaning (a hand brush or wire brush may also be required);
• grinder - necessary if you need to remove protruding parts of the reinforcement or large protrusions;
• spatulas for filling cracks on the wall surface.

Set for fastening LOGICPIR thermal plates from TECHNONICOL:

• screwdriver or drill;
• TECHNONICOL LOGICPIR adhesive foam;
• construction stapler;
• self-tapping screws;
• dowels;
• aluminum self-adhesive tape LOGICPIR;
• mounting gun, etc.

If the insulation will be laid in the sheathing, then you also need to prepare a tool for the wooden frame. This could be a jigsaw, hacksaw, scissors or angle grinder.

Stage of preparation for laying thermal insulation

Before installation, you need to measure the area of ​​the room to be insulated and calculate the number of slabs that will be required for work.

LOGICPIR thermal plates are produced with the following dimensions (length x width, mm):

• 1190x590;
• 1200x600;
• 2360x580.

To find out the required number of LOGICPIR thermal plates that will be required to insulate a garage, you need to use the following formula:

S total (total area of ​​the insulated room) / S slab (area of ​​one slab)

The result is divided by the number of slabs in the package and then rounded up. The resulting number will indicate how many packages of insulation you need to purchase to cover the room.

The walls, floor and ceiling are cleaned of debris, remnants of plaster, paint, etc. To do this, use a brush, broom and dustpan. If possible, you can take a construction vacuum cleaner. It will simplify the task and improve the quality of cleaning.

LOGICPIR floor insulation from TECHNONICOL

The TN-POL Standard PIR system can be taken as a basis for drawing up an action plan. Its advantages:

• manufacturability;
• strength;
• high installation speed;
• a vapor barrier layer is not needed.

Installation steps:

1. Make a rough screed or pour a cushion of sand and concrete. Ideally, the garage will have a reinforced concrete slab as its base.
2. LOGICPIR thermal boards are laid (using foam adhesive) with seams spaced apart.
3. The joints between the plates are covered with aluminized tape.
4. The beacons are placed and the screed is poured (a layer of at least 4 cm). For a garage, reinforced cement-sand is suitable.
5. The installed beacons are removed from the solution, the recesses left behind are concreted.

LOGICPIR wall insulation from TECHNONICOL

To effectively insulate garage walls, you can rely on the TH-WALL Thermo PIR system. LOGICPIR thermal plates will help create an impenetrable thermal insulation layer without taking up a lot of free space. The insulation is secured using both dowel nails and polyurethane foam. At the final stage, lining or plasterboard sheets are fixed to the sheathing.

Installation steps:

1. Using adhesive foam, LOGICPIR slabs are fixed to the prepared garage wall. It is important to install them with seams spaced apart. The technology does not allow the 4 corners of adjacent slabs to converge at one point.
2. The seams between the plates are securely closed with aluminized tape. This will create a solid and sealed layer of thermal insulation.
3. A sheathing made of wood or metal is installed on top.
4. Attaching to panel sheathing or drywall. Decorative plastering can also be done on top of the structure.

Ceiling insulation LOGICPIR from TECHNONICOL

A lot of heat escapes through an uninsulated ceiling. Therefore, if you worry about thermal insulation only of the walls, it will be difficult to achieve the desired microclimate inside the garage.

Installation steps:

1. LOGICPIR thermal plates are fixed onto the cleaned and prepared surface with the seams spaced apart. This can be done using adhesive foam or dowels at the rate of 2 pcs. for 1 plate.
2. To create a continuous vapor barrier layer, the joints are covered with aluminum tape. After this, there is no need to apply additional vapor barrier materials.
3. To close the structure, guides are mounted directly along the insulation. Since LOGICPIR thermal plates are very durable, this will not harm them. Then the wall panels and drywall are attached.Finally, the ceiling can be plastered.

Insulation of LOGICPIR gates from TECHNONICOL

Garage doors are the main source of heat loss from the premises. Therefore, for insulation you can use 2 methods:

• create a curtain inside the garage. To do this, you can take a tarpaulin or thick film. It is fixed to a metal profile or wooden strip under the ceiling. The option is unreliable and impractical. It won't last long;
• create a heat-insulating layer. And here LOGICPIR slabs are ideal.

Installation steps:

1. Remove the gate leaves and thoroughly clean them of dust, debris and paint.
2. Since the gates have a rigid frame, thermal plates can be laid in its cells using adhesive foam or “liquid nails.”
3. The joints between the plates are hermetically sealed with aluminum tape.
4. The thermal insulation layer is covered with OSB sheets, fiberboard or clapboard.

Advice from professionals - installing seals around the perimeter of the sashes will help to further reduce heat loss.

Insulating a garage is a job that you can do yourself if you stock up on the necessary tools and materials and follow the technology. To reduce heat loss and create a comfortable indoor microclimate, it is better to use innovative insulation - LOGICPIR thermal plates from TECHNONICOL. The products comply with GOSTs and international quality standards ISO 9001. They are safe for humans, which is confirmed by the Institute of Solution Chemistry of the Russian Academy of Sciences.
