Modern materials and technologies have already revolutionized many industries. Products created thanks to them are cheaper, more durable and more convenient. One of these materials is polyurethane foam. It is used, in particular, in thermal insulation and waterproofing.

What is polyurethane foam?
The concept of polyurethane foam is very general. In fact, it covers many types of materials based on a material called polyurethane. Invented many years ago, it has undergone many changes. That is why today we can use many of its properties, depending on our needs and goals.
A characteristic feature of this material is the foam shape, which is a collection of air-filled cells that harden under appropriate conditions and form a kind of hollow spheres. This feature makes polyurethane foam an ideal insulator. People interested in physics are well aware of how much thermal protection can be done if you leave an empty space between two glass panels or layers of other material. This is the guiding principle of hollow block manufacturers and facade designers.
The most popular types of foams used, in particular, in the construction industry are solid polyurethane foams, known as polyurethane and polyisocyanurate polyurethane foams - PIR. The latter are further improved, due to which they have higher insulation parameters in relation to temperatures.
In practice, there are also semi-rigid aerosol foams and elastic polyurethane foams. The latter are less useful for building insulation.

The use of polyurethane foams in heat and waterproofing
One of the most common applications of polyurethane foams with a high coefficient of expansion is thermal and hydrological insulation of buildings. Due to their properties, they can be used to insulate attics of residential and industrial buildings, agricultural buildings, flat roofs, production halls and many other facilities. Due to their complete chemical inertia and the absence of any environmental impact, foams are used in various manufacturing industries, as well as in contact with food or chemicals.
The fixed material does not absorb or allow moisture to pass through, so it is ideal for waterproofing foundations, basements, terraces and balconies, as well as other structures that need to maintain a dry environment. The foam is applied to the locations indicated by the spray method, so that it precisely covers each surface, fills the gaps and does not create thermal bridges.
