Insulation of the foundation of the house outside with polystyrene foam

Maintaining a cozy and energy-efficient home requires taking important steps, like insulating the foundation. Using polystyrene foam, a substance renowned for its superior insulating qualities, is one well-liked technique. In the end, this method lowers energy expenses by keeping your house warmer in the winter and cooler in the summer.

Insulation made of polystyrene foam offers defense against moisture and temperature changes. You can stop heat loss and cold air intrusion into your home by applying it to the outside of the foundation. This helps shield your foundation’s structural integrity from the damaging effects of freeze-thaw cycles in addition to improving comfort.

Polystyrene foam’s resilience to water and durability are further benefits of using it. Since polystyrene does not readily absorb moisture like other insulation materials, it is perfect for damp areas. Its simplicity of installation and lightweight design also make it a sensible option for homeowners wishing to increase their home’s energy efficiency without having to undertake major construction work.

This post will discuss the advantages of using polystyrene foam insulation for your foundation and offer a detailed tutorial on how to do it correctly. This information will help you make wise decisions and get the most out of your foundation insulation project, whether you’re building a new house or remodeling an old one.

Why is it better to choose polystyrene foam

Today’s building technologies allow developers to use a variety of insulation materials, including foam, liquid (foamed), bulk expanded clay or slag, and polystyrene foam. Why is polystyrene foam specifically recommended by us?

1. Low thermal conductivity with relatively high indicators of physical strength. Production technology involves the use of special innovative additives to improve the performance of the material.
2. Universality of use. Foam polystyrene can be insulated not only of the foundations (outside or from the inside), but also the walls, ceilings, floors, etc. D. This one greatly facilitates the process of building a building, minimizes unproductive losses to insulate the entire building. You can purchase the same type of insulation for all structures, including ceilings, walls and floors, and then use it taking into account the need for each element of the building.
3. Technology. Polistyle foam is easily cut and processed, for work there is no need to purchase special tools and equipment. Slabs can be fixed with dowels and large hats or glued. Shelf life in proper conditions is practically not limited. If for some reason the insulation of the foundation is postponed for a later date, then the quality of the material will not deteriorate.
4. Low price and long service life. By the aggregate of these characteristics, polystyrene foam has no equal among all heaters.

Where to start insulation

It is a good idea to insulate the foundation while it is being built; this is best done right after the formwork is lifted. There is less earthwork required, safety is improved, and the process is substantially facilitated. Furthermore, dangers of lessening the foundations’ supporting qualities are not included.

When insulation is installed in a residential building, there are more tasks involved, and they also cost more money. The building’s condition should be assessed and the plans for using the basements considered before insulation is installed.

1. The proximity of groundwater. If the house is located on a waterlogged area, then before starting work on insulation of the foundation, it is necessary to make lemonrance. How to produce it, we will tell you a little lower.
2. The purpose of the basements. If they are planned to be used only for storing foods or small household equipment, then insulation is done one algorithm. Completely different works must be done for foundations, the basements of which will be used for rest rooms, gym halls, etc. D.

These factors determine not only the insulation depth but also the properties and method of applying the layer of insulation.

Once the preliminary matters are settled, you must determine the building material count and nomenclature. To account for various waste and errors, the amount increases by roughly 10% during the acquisition process.

Preparation for insulation of the foundation located on waterlogged soils

Polystyrene foam is used by builders to eliminate soil bursting loads that occur during freezing or measurement. However, polystyrene foam sustains severe damage after that, reducing its ability to withstand heat. In this instance, extra precautions must be taken to ensure that the plates fulfill their primary function as a trustworthy and efficient insulation. This is possible because of the removal of surplus moisture; the earth’s coefficient of expansion during freezing decreases with decreasing relative humidity. correspondingly, the slabs require less compression effort.

Soil waters are taken as part of the preparatory work. How would one go about doing that?

The foundation drainage scheme

The foundation drainage device

Step 1: excavate a trench around the house’s perimeter, down to the foundation. 40–50 centimeters in width.

Vital. Dig very carefully; never undermine the Earth beneath the foundation tape. Should the earth be showing signs of insufficient support, allow the trench to be 5–10 cm below the foundation’s depth.

Drainage system ditch

Another advice. There are fears for the strength of the foundation? Do work in stages, each wall separately. You can dig a second trench only after the previous. This complicates the whole process, but you should not risk the stability of the building. It is not recommended to use earth equipment. It may be more difficult and harder to manually, but the risks of damage to the structures of the house are completely excluded. It’s hard to dig yourself – invite your neighbors or acquaintances to help. There is no such opportunity – use the services of construction teams. Just do not forget to control the quality of their work, frank hacks are often found. Especially in such low -skilled work.

Step 2: Consider how groundwater might be diverted. They can be removed from the area immediately or placed in designated containers. Everything is dependent upon the topography and the drainage pipes’ depth. Simultaneously, remember that the drainage system’s angle of inclination should not exceed 2-3 mm per linear meter. Dig a trench as soon as possible to install a pipe that will release water from the house. Drainage should be done if at all possible, not just close to the house. Although it is more costly, living in a country home offers significantly greater comfort.

Step 3: Install the drainage pipes around the foundation’s perimeter, making sure each pipe has the proper slope in each location. The holes in drainage pipes allow water to pass through; do not let them clog. Sand with a 20–25 cm thickness is poured on top of the geotextile-sealed pipes. Ordinary plastic is used to divert more water.

There is gravel covering the pipes.

Step 4: Recall the sand thoroughly and drift off to sleep in the remaining earthly area. Eliminate big stones as they may cause harm to the pipes.

Geotextile ends are wrapped, and soil is filled in.

Sensible guidance. Create a layer of sand up to 30 cm thick between the material and the ground to further lessen the lateral pressure of the soil on polystyrene foam. The process of installing insulation is quicker and simpler if the home is situated on a hill and there are no groundwater issues.

Step -by -step instructions for insulation of the foundation at home from the outside by polystyrene

Firstly, let me state that it is best to heat the foundations only if the basements are going to be utilized for purposes other than food storage. The truth is that all homes need to have purges to allow for the natural ventilation of subterranean spaces; otherwise, the initial supporting qualities of wooden structures will be rapidly lost.

Fiction within the framework

Fungi and rot damage the tree in the absence of proper ventilation, which can have very unpleasant effects. Ventilation is necessary regardless of the benefit of antiseptic impregnations. However, since air is always moving beneath the floor, there is no need for foundation insulation and no benefit from thermal energy savings. In these situations, the only way to conserve heat is to properly insulate the floors to ensure comfort in the first floor’s premises.

Step 1: excavate a trench down to the depth of the foundation.

Dig carefully, keeping in mind the soil’s structure, and heed the advice above to avoid weakening the structure’s supporting elements. You can heat one basement, but don’t count on this operation to save much in the way of results. Time and money lost will never be made up for.

Step 2: Clear the surfaces of the ground and verify that the planes are linear. A perforator is required to remove any ledges that are larger than one centimeter. After the concrete dries, it is simpler to clean its surface. A standard hard plastic brush will work. Using a metal brush yields marginally better results, but such work demands tremendous physical exertion.

Step 3: Take measurements of the surfaces and consider how the sheets will be cut. Make an effort to reduce waste as much as possible; pieces should be as large as possible.

Vital. Small segments of insulation can be inserted at the joints, but not in the corners of the foundation. The adhesion strength is inadequate and the foundation’s surface is uneven. Large pieces have a higher chance of staying in place than small ones, which are much more likely to fall off.

Step 4: Decide how the plates will be secured to the foundation. Both mounting foam and cement-based adhesives are suitable for use. Mounting foam is more recommended if the foundation plane is flat. Use glue to align trouble spots if there are large bumps; however, a lot of material will be lost during alignment.

Applying glue and foam uses slightly different technologies.

First, the sheets are fixed with mounting foam

It is best to buy a professional gun right away because it is inexpensive and makes the work much easier. Furthermore, the material in the pistol is suitable for continued use for an extended period of time. The leftover foam freezes the following day without it. The material, which has a thickness of roughly 1 cm, is applied to the plate’s entire perimeter as well as its two diagonals. Remember that the volume can be increased up to three times.

Adhesive is applied to the insulation plate.

Using mounting foam

Vital. The foundation walls need to be completely cleared of debris and dust before polystyrene is applied. Additionally, the concrete’s surface needs to be moisturized. Any spray gun or wet roller will work. The foam cylinder must be tightly closed after application. You should wait five minutes before adhering the sheet to the foundation’s wet surface.

Troth fixation is carried out in turn; their positions are verified with a flat line. The plate protrusions in the docking locations should not be larger than 0.5 cm.

2. Glue-based sheet fixing

Any brand will do; even the least expensive ones work well. After that, the plates will press against the earth.

Polystyrene foam adhesive

Which foamplex compositions can be adhered to the foundation?

Give the basement, which is the portion of the foundations above ground, more consideration. After that, the external surfaces will need to be covered with ornamental tiles or plastered. Put more glue on the aboveground portion; it should cover the whole surface.

Before adding a dry mixture to the container, water is added during the glue preparation process. If you don’t follow this order, the solution won’t be able to be mixed completely to the same consistency, which will cause dry material to remain in the corners of the container and cause problems when operating.

Step 5: Use bitumen mastic or primer to swell the surface. Mastic is preferable in extremely wet situations; primer should be sufficient in normal circumstances. By doing this, the adhesion coefficient is raised and a trustworthy hydro-barrier is created.

Step 6: The residence’s climate zone is taken into consideration when choosing the thickness of thermal insulation. For the middle strip, five centimeters is sufficient; in colder regions, the thickness rises to ten centimeters. It is preferable to use two 5 cm thick plates rather than one 10 cm thick plate, as experience has shown. There will be a slight increase in work hours, but the quality will significantly improve.

Indicators of Penoplax plates

As you adhere the plates in a checkerboard pattern, the joints between the first and second layers should close. Furthermore, this technique makes it simple to level the foundation’s surface.

Step 7: Whole sheets should be next to each other in the corners, and spacers of the appropriate size can be used to seal the gaps between them. Insulation needs to be installed to close the foundation angle.

Step 8: Use foam to fill in the joints once the plates are securely glued. After drying, the protruding foam on the foundation’s basement is cut and left in place in the ground. There are suggestions to further secure the sheets with dowels, but this is unnecessary. Subject to the recommended technology, the glue’s strength is sufficient to withstand the basement’s finish, and in the lower portion, sand or earth will be used to press the insulation against the foundation.

Foundation and procedure for insulation

Once the primary insulation work is completed, you must begin Applying the reinforcing grid and pouring the sheet’s corners and faces with metal corners.

Step 1: Use a grid to purchase a perforated metal profile and prepare the corners for reinforcement. There are many different compounds available today that glue can be used with. They don’t purchase the priciest materials, so their differences in quality are minimal.

Aluminum is perforated in the corner and has a grid reinforcement.

Step 2: Prepare the adhesive mixture as directed; do not permit the formation of dry lumps. Using the drill and a specialized tool to tamper with the solution is exceedingly challenging. In the event that such a factory option is unavailable, you can create it on your own. To accomplish this, cut a 40 cm long flat reinforcement and weld to it from multiple angles, slightly curved in the opposite direction of the cutting cutter’s shaft rotation. If the solution is being prepared in plastic containers, make sure that all of the reinforcement’s sharp edges are removed. If not, any carelessness could result in the development of through holes.

Making the adhesive mixture

Step 3: Cover the corner of the sheet with glue up to 0.5 cm thick. Assemble a corner and a section of the reinforcing stack to the required size. To cut the materials, use a regular construction knife.

Step 4: Position the cornered grid onto the prepped surfaces, firmly press the components in place, and then dab a thin layer of glue on top. Angles are shielded from mechanical harm in this way. To prevent damage from rodents, it is advised to plaster the entire surface of the polystyrene foam in the future.

Step 5: You can move on to reinforcing surfaces once all angles have been strengthened. Rolls of the grid, each about one meter wide, are sold. It is simpler to cut the entire roll at once without unwinding if the foundation height is less than this value. Make use of a standard metal hacksaw. Place the mesh roll on a level surface, cut it off carefully, and rotate it slightly every time.

Step 6: Cover the surface with glue. Give yourself enough time to glue the grid and apply a second layer of glue before preparing a sizable portion of the foundation. The prepared surface area is determined by the adhesive’s properties and your practical abilities. Some take 30 minutes to dry, while others require an hour. Look over the directions provided by a specific brand.

Step 7: Using a large spatula to press the grid is preferable. Try not to get rid of every trace of the tool; a few small furrows will help the basement finish material clutch work better. Besides, if the screed is going to remain unnoticeable, why grind it?

Foam plaster: a procedure

Moreover, depending on the selected technology, work continues. After the glue has cooled, the subterranean portion can be carefully filled with dirt or covered in sand. Every ten to fifteen centimeters, carefully trim the ground. Take your time making blindings; allow the earth to fully contract before starting.

Polystyrene foam insulation for your home’s foundation has many useful advantages. First of all, it offers superior thermal insulation, which lowers energy expenses and helps control indoor temperature all year round. Since the foundation walls are usually in direct contact with the cooler ground, placing the insulation on the outside of the foundation creates a barrier that reduces heat loss through the walls.

Additionally, polystyrene foam is simple to work with and lightweight during installation. Because of its resilience, it will remain effective for an extended period of time without deteriorating or being damaged by moisture. By shielding the foundation from temperature changes and moisture intrusion, this kind of insulation also helps to maintain the foundation’s overall structural integrity and may even lengthen the foundation’s life of your house.

Living spaces above the foundation can also be more comfortable if the foundation is insulated with polystyrene foam. All year long, it improves indoor comfort by eliminating drafts and cold spots that are frequently linked to uninsulated foundations. This increase in thermal efficiency makes a house more sustainable and energy-efficient in addition to improving comfort.

In conclusion, choosing to use polystyrene foam insulation for your home’s foundation is a wise investment that has several advantages. For homeowners aiming to improve their living conditions and the longevity of their homes, this insulation method proves to be effective and advantageous, offering benefits like reduced heating costs, improved energy efficiency, and increased indoor comfort.

It makes sense to insulate a home’s foundation with polystyrene foam on the exterior to increase energy efficiency and provide moisture protection. Polystyrene foam is added as a layer around the foundation to create a barrier that lowers heating and cooling expenses and helps control indoor temperature. Additionally, this technique aids in preventing moisture seepage into the foundation, which over time may result in damage. All things considered, using polystyrene foam for insulation is a sensible way to improve a home’s comfort and longevity.
