Types and features of insulation of external walls

Apart from their low thermal conductivity, the primary characteristic of outer types of insulation is their ability to withstand various environmental factors such as high humidity, rain, snow, sunlight, and extreme temperatures. Warming "pie" is produced by new technologies in house wall insulation.

His plan uses a device with multiple layers, each of which addresses a different issue:

The proper arrangement of the layers becomes crucial in this situation.

Consequently, insulation gains:

Durability.
Efficiency.
Convenience.
Small value.
Lack of problems with dampness.
Protection against mold.
Protection against rodents and insects.

The most widely used materials for insulating homes from the outside are:

Polystyrene or polystyrene foam (cm. How to warm the walls with foam on the outside with your own hands). It is a porous material, which is obtained by foaming, consists of fine-mesh granules that are well sintered together. Foam plastic is made of different densities, the higher it is, the more durable the material will be. Its advantages:

durability, up to 60 years;
resistance to moisture;
resistance to bacteria;
withstands temperature changes in the range from (-40 ° C) to (+ 40 ° C);
not high price.

Warm plaster. This type of external building insulation is a cement, gypsum or lime binder with various fillers that give it thermal insulation properties. This material consists of:

perlite sand;
polystyrene foam;
sawdust;
perlite;
vermiculite.

The insulation has the following benefits:

fire safety;
environmental friendliness and safety for humans;
increased thermal insulation properties;
high practicality;
multifunctionality;
not high cost.

Basalt insulation of house walls. Can be used:

for external and internal insulation of a building;
for insulation of attics, loggias and balconies.

The material includes basalt fiber, which is produced by melting and then processing natural minerals to create fiber. Its primary attributes are:

increased porosity, up to 70%, which ensures low thermal conductivity;
high temperature resistance;
chemical resistance;
vapor permeability, which guarantees the dryness of the material even at fairly high humidity in the atmosphere or room;
high strength;
the result is an environmentally friendly wall of the house with insulation;
lightness of the material.

How to insulate external walls with isolon

One substance associated with reflective thermal insulation is isozolon. In this instance, heat is a unique kind of radiation that reflects well off of certain surfaces.

Izolon reflects heat energy back into the space, preventing it from escaping. Large-sized rolls of the material are produced.

Advice: Make sure you accurately calculate the amount of material needed before using isolon to insulate a house’s walls.

In the video on this page, you can see an example of an estimate for using isolon to insulate a wall in a house. To ensure that the insulation is solid and has better reflectivity, you must also buy aluminum tape to join the joints of the insulation for high-quality isolon wall insulation.

Between the outer wall and the finishing layer.
Between two walls.

In each scenario, the room’s thermal energy:

Will be reflected.
Cold air located outside will never penetrate the building.

The reason for this is that isolon insulation is foil-coated on both sides; however, in actual use, one-sided foiling is more common.

Advice: Each option for installing insulating material is appropriate for a specific type of building, so consider the design features of the house before selecting one of the options.

For optimal results, a 15–22 millimeter-thick empty space is placed between the wall and the insulation. To do this, rails of the same thickness are pressed into the wall’s surface. Reiki should be spread out in a checkerboard pattern with a maximum step size of one meter and a maximum length of 1.5 meters for each section.

The material is mounted by a stapler or small nails.

Advice: When putting in isolon, you should keep an eye on how well the material is being adhered with aluminum tape.

A rack layer is also applied on top of the insulation, on which finishing coatings will be attached.

When using isolon to warm the exterior walls of a house, the only qualitative outcome will be the creation of air gaps that aid in thermal reflection, preventing cold air from the street from entering the space. It is preferable to use foil insolon on both sides to insulate a country home’s walls. Since this material does not absorb moisture, it is best used in the (-65 °C to +120 °C) temperature range.

Topic	Description
Choosing Insulation Material	Select the right insulation material, such as foam board or mineral wool, considering your climate and wall type.
Surface Preparation	Clean and dry the wall surface thoroughly before applying insulation to ensure it adheres properly.
Installation	Install the insulation panels tightly to avoid gaps, securing them with adhesive and anchors if necessary.
Adding Protective Layer	Apply a weather-resistant layer, like plaster or cladding, over the insulation to protect it from the elements.
Sealing and Finishing	Seal all joints and edges to prevent moisture from getting in, then finish with your chosen exterior coating.

Maintaining your home’s exterior walls properly is about more than just staying warm. It’s about making a cozy living space that withstands weather and lasts for many years. By making sure your home is energy-efficient and adhering to recommended insulation guidelines, you can eventually lower your heating and cooling expenses.

Selecting the appropriate materials and installation techniques for your unique climate and building structure is also crucial. By taking this into careful consideration, you can avoid common problems that can reduce the effectiveness of your insulation, such as moisture build-up or thermal bridging.

In the end, spending money on high-quality exterior wall insulation is an investment in the future of your house. It raises energy efficiency, improves comfort, and may even raise the value of your home. Long-term financial security and the preservation of your house are ensured by taking the time to properly insulate.
