5 Best Spray Foam Insulation for Exterior Walls

What is Polyurethane Foam Spray? How Is It Used In Insulation?

Polyurethane is among the exterior cladding materials with the best heat conduction coefficient used in the building sector with a closed cell structure of 90 – 95%, thermal conductivity coefficient (X) of 0.024 W / mK.

HC Pentane gas used in the production of polyurethane foam is trapped in the closed cells of the polyurethane and adds added value to the insulation feature. This gas used in the blowing process does not have any damage to the ozone layer.

Polyurethane can also be produced in very dense forms. This density can vary between 30 – 40 kg / m3 and 1200 kg / m3. Increase in density sheathingIt has a linear effect on it.

They are prominent insulation materials in the production of composite products, especially sandwich panels, with their ability to adhere to almost any surface, including polyurethane metals.

This adherence stability continues between -30 and + 80 ° C without any deformation. The change in thermal conductivity of polyurethane as a result of aging is at most 15%. This means that there is a lifetime equivalent to the life of the building.

The fact that polyurethane is not affected by chemicals ensures that it is preferred according to the place of use. Polyurethane insulation materials are applied by casting or spraying method .

Polyurethane Foam Interior Wall Insulation

Polyurethane foam material comes from the reaction of diisocyanate with polyols. Thanks to its chemical structure, it is a very flexible and durable material. Foaming property is obtained in direct proportion to the polyol used.

When cured by foaming, it can go up to 50 times its normal volume. Thanks to its foaming structure, it is the most effective substance in the world in thermal insulation. Especially, it is the most effective method preferred in building thermal insulation.

Polyurethane foam interior coating processes are applied to the exterior facades of the building in cases where it is not possible to cover the exterior. Since it does not require the use of scaffolding and cranes, it is easier and more economical than exterior applications.

It can be applied easily from room to room. In this way, the thermal insulation of the buildings is easily provided. Polyurethane foam interior wall coatings allow a temperature increase of 2 to 4 degrees on the surface.

Thanks to this feature, it helps you consume less fuel and heat your home more easily. In the summer months, your home is provided to be cooler. The advantage in thermal insulation can be achieved both in summer and in winter.

You get a more suitable environment for living thanks to the fact that it is hot in winter and cool in summer. For a comfortable life, choose the polyurethane foam coating method in the thermal insulation of your home.

The life of the polyurethane foam coating, which is the best material in the world in thermal insulation, is as long as the life of the building. So you never have to think about thermal insulation again.

Since interior thermal insulation applications provide high thermal insulation even in a thin application, it causes minimum space loss. After the polyurethane foam interior cladding is made, it does not cause aesthetically negative consequences, as it can be made of plasterboard, plastered coating or brick coating.

Polyurethane foam, which is in the B2 combustion class, is non-flammable, thus slowing the spread of fires. The polyurethane foam coating provides a certain level of sound insulation as well as thermal insulation.

In this way, the noise decreases and your quality of life increases. With its breathing feature, it can be applied easily without requiring a vapor barrier. Thanks to the spray spraying method, it does not create joints and does not allow any heat bridge to form.

Polyurethane Spray Exterior Wall Insulation:

The exterior of your living spaces with Polyurethane Spray Foam. Thermal insulation application is fast, effective and economical. Exterior thermal insulation applications with Polyurethane Spray Foam are completed very quickly with the help of scaffolding or crane method.

Polyurethane Spray Foam exterior thermal insulation application; The specially equipped machine in the mobile isolation vehicle and the 2-component liquid Polyurethane Spray Foam material is transported to the application area with the help of a heated hose and sprayed on the exterior of the building with a special spray gun under high pressure.

Spray Polyurethane Spray Foam does not deteriorate in contact with water and does not separate from where it is applied. It is resistant to acid, base and salty environments. Spray Polyurethane Spray Foam does not contain bacteria and insects, does not odor, does not rot, is long-lasting and environmentally friendly.

External walls are normally the largest surfaces from which heat can escape from inside buildings in a fairly uncontrolled manner. Between 100-150 kilowatt-hours of electrical energy or 10-15 cubic meters of gas from 1m² of uninsulated wall each year, heating energy is lost through uninsulated walls.

This can be reduced by up to 90% with Polyurethane Foam exterior thermal insulation. With Spray Polyurethane Foam, exterior thermal insulation applications are completed very quickly with the help of scaffolding or crane method.

The fact that Spray Polyurethane Foam can be applied with the help of a crane in blind facade areas where traditional thermal insulation applications cannot be performed by installing scaffolding makes exterior thermal insulation applications with Spray Polyurethane Foam fast and unique in areas where application is difficult.

The form of the surface to which Spray Polyurethane Foam is applied is not important. Regardless of the shape of the surface, it takes the surface form without the need for any adhesive and mechanical fixation, and it adheres by eliminating heat bridges with its uninterrupted coating ability.

It is not affected by impacts, jolts, tectonic movements and vibrations since it has a very strong adhesion feature. It is flexible, it works with the structure. The life of the adhered foam is equivalent to that of the building.

With the application of Spray Polyurethane Foam, the decorative coating options (plaster-paint, composite exterior coating, granite or natural stone coating, etc.) applied as the final layer on the heat-insulated exterior protect the building against water, mechanical effects, abrasion and ultraviolet effects of the sun.

  • Provides uninterrupted insulation that eliminates thermal bridges.
  • It does not deteriorate in contact with water and does not separate from where it is applied.
  • Thanks to its water vapor permeability, it allows the surface to breathe.
  • It allows for thermal insulation covering of 500-750 m² per day.

Performance of ICYNENE insulating foams to insulate walls

Foam wall insulation is one of the best choices for protecting a building . ICYNENE products provide overall insulation for wall walls thanks to their remarkable properties. Each contributes to reducing the energy expenditure of the building treated.

Thermal resistance

As with any insulation in a building, thermal resistance is the first criterion of choice. For a wall, the minimum thermal resistance to be reached in order to benefit from certain financial aids is R = 4 m².K / W.

It is the EWC steering committee, which is attached to the Ministry for the Ecological and Inclusive Transition, which has set this minimum thermal resistance required. This resistance depends above all on the thermal conductivity (lambda λ) of the insulation.

The lower the thermal conductivity, the less insulation will need to be applied. It is an essential data for the insulation of the walls because it mechanically reduces the interior spaces.

With its low conductivity, ICYNENE foam is therefore an ideal insulation product for walls. Thanks to the excellent thermal resistance of the sprayed polyurethane foam which can be achieved, the occupants benefit from a pleasant interior temperature in summer as in winter.

Air tightness and humidity control

In addition to good room ventilation, which is compulsory for renewing the air, wall insulation must behave well in difficult conditions. Because assaults are daily.

  • Almost 99% of moisture is carried in the air and can develop when cooking or showering. If moisture carried in the air passes through the walls, it can condense there, causing mold to develop.
  • Air currents cause hot and cold spots. Cold spots are found in poorly insulated exterior walls or in areas that are hard to reach and prone to condensation.

By controlling humid conditions , indoor air is of better quality. In certain situations, an insulation capable of regulating humidity will be more suitable than the application of a perfectly waterproof insulation. And conversely if it is necessary to make vertical walls completely airtight and moisture proof.

Good news for the customers of our network, ICYNENE offers all of these solutions. Some insulators in our range thus have a great capacity to regulate humidity. Other insulating foams, on the contrary, are capable of forming an airtight and water vapor barrier.

Construction efficiency / energy renovation

Wall insulation should be considered from the design phase for a new building project. The teams of the ICYNENE network advise their private or professional clients (developers, architects, craftsmen, etc.) on the best insulation to choose.

Advantages of wall insulation using ICYNENE foam spraying

The characteristics of polyurethane foam give it a large number of advantages for insulating the walls of a building. Perfectly suited to most supports (masonry, wood, etc.), the insulation conforms to all shapes during its expansion.

Elimination of thermal bridges

As part of overall insulation, insulating walls concerns the elimination of thermal bridges as much as airtightness.

Thermal bridges must absolutely be treated to avoid energy loss. Particularly sensitive points have to be managed: connections with the ground as well as openings (windows) or electrical equipment (sockets, switches, etc.).

These must be protected during the installation of insulation on the walls while considering their accessibility after the work. Insulating only the walls that are more / less exposed to the sun (depending on the climatic conditions specific to the place where the building is located) is a miscalculation in terms of efficiency and savings in the medium and long term.

Mechanical resistance

For the wallet of our customers and for the planet, it is essential to install a wall insulation system that resists over time. That is to say, which does not degrade and which does not settle under its own weight.

The quality of the installation is as important as the properties of the insulation. As ICYNENE foam does not settle, it partly ensures the longevity of the insulating system.

Speed of execution

The in situ application is rapid even if the preparation and cleaning phases of the site must be scrupulously respected. The other trades can return to work on site the day after the walls are insulated by the ICYNENE teams.

Wall insulation: power 3 benefits

The objective of wall insulation work is above all to improve the energy performance of housing or of the tertiary / industrial building. You should know that 20 to 25% of heat loss in a building is caused by poor insulation of the walls. It is the second source of heat loss after the attic / roof.

The balance is even heavier by adding the energy losses from windows: + 15%. Insulating the walls with ICYNENE expanded foam causes a decrease in energy consumption with a triple beneficial effect.

Quality of life of occupants

Well-insulated walls have an immediate impact on the well-being of the inhabitants of a house, for example. No more feelings of cold walls! During hot weather, the thermal resistance of the insulating system preserves the interior temperature.

Lower energy costs

The more efficiently a building is insulated, the less energy it consumes. The use of air conditioning or heating is then less numerous and less important. And consuming less automatically means spending less.

Preservation of the environment and natural resources

As a direct consequence of the previous points, efficient wall insulation helps protect the environment. The choice of an insulation with the lowest environmental impact is made with regard to its manufacturing process, its longevity or even the management of its obsolescence.
