Even minimal inadequacies related to the insulation of a building can be responsible for significant heat loss in the future, and any mistakes made during installation will not become apparent immediately, but only several years after the construction has been completed. Their detection and repair are difficult, time-consuming and quite costly processes. Therefore, no one needs to be convinced that choosing the best quality insulation materials and methods is crucial.

Effective insulation

When choosing insulation materials, thermal insulation parameters (e.g. low thermal conductivity λ), low water absorption and properly selected mechanical strength are rightly considered to be the most important. The aforementioned parameters and the correct execution of the insulation are important, but equally important is a professional and reliable approach to the investor. A detailed conversation, the aim of which is to familiarise the investor with the material, with all its features and properties, will result in the investor making a fully informed choice of a satisfactory solution.

The perfect warming? Above all, insulation must be professionally carried out

The builder should be well acquainted with all the advantages, but also the disadvantages, of the insulation he is considering choosing. There is no ‘ideal material’ on the construction market. Polyurethane (polyurethane insulation) also has its advantages and disadvantages, which can be exacerbated by the wrong choice of application surface and poor workmanship. Incorrect workmanship applies to all insulation materials available on the market and is one of the biggest risks the uninformed investor is exposed to. When deciding on insulation, it is therefore worth entrusting its application to a specialist recommended by the manufacturer.

Effective protection against moisture

Spray foam polyurethane insulation solution

One of the solutions available on the market for effective building insulation is Crossin Insulations®, which are, among other things, polyurethane spray foam insulation systems.

Polyurethane – good insulation

Compared to other materials, closed-cell polyurethane foam has one of the lowest thermal conductivity coefficients (λmean, i ≤ 0.021 W/(m-K)).

Its strength parameters are also outstanding, which is extremely important for external insulation, e.g. for foundations, flat roofs or ‘underfloor’ surfaces. For example, the compressive strength at 10% relative strain is 400 kPa. This value is several times higher than the accepted value, but it gives the entire building structure additional reinforcement. Importantly, this increased strength does not in any way affect the insulation properties or the cost of the material itself. The reason is that the properties of polyurethane insulation with increased strength, are better despite comparatively smaller (often quite significantly) thicknesses.

Crossin Insulations® foam is also characterised by reduced water absorption (Wp ≤ 11 kg/m2), so that it retains its thermal insulation properties despite the passage of years and changing weather conditions in such a demanding and difficult environment as the ground.

Effective insulation means no thermal bridges

Further advantages of Crossin Insulations® brand polyurethane (PUR) foam also include: excellent adhesion to various building materials (including concrete blocks, hollow bricks and bricks), high performance and a seamless application method.

Innovative and state-of-the-art application technology using professional, high-pressure machines effectively eliminates the appearance of possible thermal bridges and allows a uniform, seamless and energy-efficient coating to be created. In addition, due to its comparatively low weight, spray-foam polyurethane insulation does not weigh down the building structure.

Spray insulation. Polyurethane in many ways

An interesting differentiator when it comes to Crossin Insulations® brand spray insulation is its dedicated approach for specific applications.You can find other systems for insulating external surfaces and others for insulating internal surfaces.

Crossin Insulations® are also systems that have been separately designed for attic insulation, ceiling insulation or wall insulation. In addition to excellent adhesion, they are distinguished by their very rapid foaming, so that the liquid form of the sprayed system does not drip or run off, which could have a negative effect on the final thickness of the insulation and heat loss in the house.

In the case of dedicated systems for external flat roof insulation or floor screed insulation, the distinguishing feature is the slightly slower foaming, which allows the system to spread better over the surface to be insulated. Crossin Insulations® spray insulation also provides consistent performance over time and, thanks to Bio Defence Technology, protection against mould, fungi and other micro-organisms.
