Polyurethane foam insulation is a modern and highly effective method of the thermal insulation of buildings. When applied by spraying, it reaches even the smallest of gaps. It provides the permanent and damage-resistant insulation of a house, improving living comfort, and reducing heating bills.

PUR foam thermal insulation — how the thermal-insulation spray method works.

One of the most-popular materials for building insulation is polyurethane foam. The advantages and disadvantages of other insulation methods make it possible to confirm that it is one of the most-effective ways to retain heat inside a building. PUR foam insulation is characterised by a short application time and high efficiency. Discover its greatest advantages and see why more and more people are choosing to spray house insulation. Do not hesitate — choose polyurethane-foam insulation.

Polyurethane foam’s advantages — lower heating costs

Polyurethane foam’s advantages. The advantages and disadvantages of other thermal-insulation materials support the assertion that insulating a house with wool or polystyrene foam does not always bring measurable benefits. In the case of polyurethane foam, the list of advantages is impressively long. One of these is undoubtedly the lower costs of heating a house. The thermal-insulation properties of this material are extremely high. The elimination of thermal bridges, thereby blocking heat-escape from the house’s critical points. This allows the retaining of heat in the winter and prevents heat from entering during the summer.

This advantage of polyurethane foam contributes to a significant reduction in electricity and fuel costs. The temperature in each room will be maintained at a constant and convenient level. Minimising heat losses has a discernible impact on reducing heating costs. However, this is not the only advantage of polyurethane foam.

Quick application — another advantage of polyurethane foam

The strong point of polyurethane foam is its quick and easy application (of course, by a specialised team). PUR foam is applied using the spray method — it increases its volume several-dozen times and cures at a rapid pace. Spray insulation, therefore, takes much-less time than insulation with other insulation materials.

The advantage of polyurethane foam is its easy application in the loft. The material adapts perfectly to oblique and difficult surfaces. Thanks to its expansion, it penetrates into the tiniest of gaps, preventing the formation of thermal bridges. For slanted ceilings and cramped spaces, it is best to choose polyurethane foam. The disadvantages of other thermal-insulation materials make it impossible to achieve measurable heating effects on difficult surfaces

Are there any other advantages of polyurethane foam?

Polyurethane foam, both open-cell, e.g., Purios E, and closed-cell, e.g., Purios H, has a low heat-transfer coefficient λ, making it one of the best thermal insulation materials. The material is highly adhesive to the ground, resistant to damage, and extremely lightweight — it does not overload a buildings' structure. Furthermore, foam insulation is 100% safe for allergy sufferers and animals. It does not create dust, or contain allergens or harmful gases. It maintains a high level of thermal insulation for many years. Are there any disadvantages of PUR foam?

Polyurethane foam thermal insulation — disadvantages

One of the most-effective methods of insulating buildings is undoubtedly PUR foam thermal insulation. An apparent disadvantage of this insulation method might be its price — compared to other methods, it might seem to be too expensive. It turns out that its price is comparable with alternative insulation methods. All costs will be recovered over the next few years, and the durability of the PUR foam insulation is impressively long. When you compare all the advantages of polyurethane foam insulation, the disadvantage in terms of price becomes insignificant.
