Insulation of facade with polyurethane foam

Polyurethane foam has long been on the list of the most popular insulation materials for facades. This material has been used for over 50 years, providing excellent energy-saving technology indicators. It can be used both outside and inside, using it in the construction of residential buildings, office buildings, the transport sector, and communications.

Insulation of facades with polyurethane foam: overview of the material

The basis of the material for facade insulation works with polyurethane foam is plastic. Its features include the presence of 90% air in the cavities of the finished product. After complete hardening, a 5 mm layer of foam acquires the characteristics of a reinforced concrete panel, which perfectly protects against noise and provides energy-efficient insulation of houses.

There are two types of polyurethane foam insulation on the Ukrainian construction market, which determines their scope of application and installation specifics:

Hard polyurethane foam

This format is ready-to-use sheets, used mainly for external wall insulation with polyurethane foam. They provide a tight fit to the wall, preventing condensation from appearing on the surface. This type is part of sandwich panels. Products of this type allow you to save a lot of time when creating thermal insulation of the facade with polyurethane foam.

Foam

In essence, it is a sprayed insulation for the facade, which is applied during the construction process. This type is very popular and in demand due to the simple preparation of the substance. In addition to facades, a certain thickness of the polyurethane foam layer for insulation helps to provide protection from the cold for windows and doors, roofs, pipelines.

Technological process of facade insulation with polyurethane foam

Waterproofing and insulation of the facade with sheet polyurethane foam implies the need to fix it to the wall using a special adhesive composition. If necessary, the sheets are additionally attached to the base using dowels or other elements. The technology of insulation of the facade with polyurethane foam by spraying involves the following stages of work:

• cleaning the surface to be treated from the old layer of materials, dust and dirt;
• installation of boards or profiles on the surface;
• spraying polyurethane foam on the facade in the direction from the bottom up, carefully filling the void with foam;
• removal of excess material that protrudes beyond the frame;
• plastering and decorative processing using paint, siding, plastic panels.

The cost of insulation with polyurethane foam in Kyiv is quite affordable, while differing in a quite sufficient period of operation. The service life of insulation with polyurethane foam is at least 70 years.

Pros and cons of insulation with polyurethane foam

This material provides seamless coverage in the optimal time. In comparison with polyurethane foam and mineral wool for facades, this material is lighter, has low thermal conductivity and is easy to process.

Polyurethane foam provides excellent adhesion to vertical and horizontal surfaces, preventing the appearance of cold bridges. For effective insulation, it will be quite sufficient to form a layer 25-30 mm thick.

Experts attribute the following to the disadvantages:

• aging of the material under the influence of ultraviolet radiation - therefore, it is necessary to carry out installation in compliance with the technology;
• increased flammability, requiring the use of fire retardants;
• destruction of the structure due to the expansion of the foam when applied excessively.

All these problems can be avoided if you insulate a private house with polyurethane foam or other objects in compliance with the technology provided by the manufacturer.
