PUR foam insulation

Spray insulation serves to insulate buildings; it is quite different from traditional insulation. This is both the latest and also the most accurate way to stop heat transfer through walls, roof and other building partitions.

Closed-cell foams

The closed-cell PUR foam is a modern material for insulating houses and other buildings. Thanks to its excellent insulating properties, this solution is an uncompromising one.

Open-cell foams

The open-cell PUR foam is a very good and constantly improving material for the thermal insulation of buildings. Unique properties, neutrality to health and openness to diffusion are just some of the advantages of this modern building material.

What is spray insulation?

This is a method for insulating roofs, walls, ceilings, floors and foundations with polyurethane foam. It is simultaneously the only type of thermal insulation that is free of gaps, joints, holes and other thermal bridges. Spray insulation is the fastest, safe, durable and effective way for you to enjoy a comfortable temperature at your home.

Spray insulation combines the product and the service. As a result, you get the highest quality foam and the professional service of a certified application specialist.

Advantages of spray insulation

This particular method of spray polyurethane foam insulation carries with it several unique advantages. The knowledge of the differences between spray insulation methods comes in very handy during the construction phase of a house, but also during thermal modernisation.

Pros:

  • Very good insulating properties – both the foamed polyurethane and the gas enclosed in the foam bubbles effectively retain heat, more efficiently than other materials,
  • Foaming in seconds – this is how long it takes for the two liquid components to react and turn into foam which completely fills gaps and slots,
  • Adhesion to the sprayed surface – the polyurethane foam adheres permanently to the substrate, making the use of any installation system redundant,
  • Stability of parameters – the lapse of time or the effects of moisture and other factors for that matter do not alter the material’s most important characteristics, that is to say thermal conductivity or reaction to fire class and volume,
  • No thermal bridges – these are imperfections in the insulation layer through which heat escapes; they generally occur at joints, adhesions, openings and slots,
  • Safety – consider it in every way possible, as the foam is neutral to health, to the environment; it is a self-extinguishing material; it does not cause the spread of fire and prevents the growth of micro-organisms (such as mould).

Disadvantages of spray insulation

Of all the common materials used to insulate against heat loss, the foam is the latest and most state-of-the-art. It uses more than a dozen components, regularly tested; some of them are replaced with better ones. This optimisation makes it difficult to find flaws in the solution as well as in the foam itself. However, it is worth pointing out some information that should be taken into account when insulating a home.

Cons:

  • Method of application – spray insulation necessitates that professional application specialists operate professional spray equipment. The spray insulation of a building by the commercial method is ruled out.
  • Thinner layer – the high effectiveness of the polyurethane foam means that a thinner layer can be used than with other materials. As a result, the architect has to consider a different material in the house design.
  • Acoustics – the foam has noticeably similar sound insulating properties to wool. Opinions about the inferior sound insulation of foam are based on the fact that it is a thinner layer than other materials.
