Efficient. Polyurethane foam is an insulating material that also contributes to energy savings. Characteristics, properties, applications and economic advantages.
The energy efficiency of architectural works is key to achieve direct savings through the reduction in consumption in air conditioning (either in the initial investment or in daily consumption). In addition, this attribute allows to generate greater comfort at a lower cost.
The only way to achieve this goal is through efficient thermal insulation. In this sense, among the possibilities currently presented by the market is the rigid polyurethane foam, which provides a concrete solution to the high demands of sustainable projects.
Due to its high thermal effectiveness, this material has marked advantages in the price-quality ratio compared with other insulators. This has made it become a leading product, say from the company Hi Tec Polyurethane.

Main features
Multiple conditions make polyurethane foam a highly chosen material when selecting a product for the insulation of homes. Among the main virtues that are recognized, are:
- · Thermal insulation: as it has a very low coefficient of thermal conductivity, it facilitates significant savings in the use of energy for air conditioning. In this way, it favors sustainability and promotes environmental care.
- · Water-repellent insulation: protects from moisture. In addition, placed in the correct densities, guarantees impermeability.
- · It is good acoustic insulation: it generates a barrier against the annoying noises of the environment.
- · Anti-condensation: forms a monolithic layer without joints, solving the problem of internal rain.
- · Resistant to fire: it is a material qualified as self-extinguishing.
Properties
But that is not all: beyond its own characteristics, in terms of versatility at the time of applying it and its result in time, a series of properties is attributed to it, among which are:
- · Ease of application for its spray system, which reduces the cost of labor and the time of installation.
- · Application in construction sites or finished buildings.
- · Application "in situ".
- · Prolonged duration
- · Excellent adhesion to all types of construction materials.
- · It is continuous: it eliminates thermal bridges, with the consequent saving of energy.
Application
The application of polyurethane foam in situ by spray system provides excellent thermal insulation and anti-condensation, which guarantees a perfect waterproofing. This is due to the high density of the material, in which a barrier is achieved that prevents the penetration and filtration of water.
One of the most important resulting benefits is maximum insulation with minimum thickness.
Even in the case of in situ projection (normally used in interior and exterior facades), other performances can be added: high adhesion, effective adaptability, impermeability, continuous application without joints or thermal bridges.
Its adhesion occurs on any material and, once placed, does not crack before changes in temperature or expansion.
Where can you apply
In family homes, you can apply on the roof or below it, whatever your material. It can also be used on walls, where good results are achieved.
It is highly recommended in double wall systems, as an effective insulator against moisture.
However, its use has also been generalized in large-light houses, where it reaches optimal levels of temperatures over large areas.
These characteristics have led to its use being extended to animal breeding sites and also to cold storage chambers, storage tanks and silos and, in general, to industries of all kinds.
Economic benefits
Technicians and specialists also highlight a series of economic advantages. For them, the application affects construction costs and housing services.
- · Significantly reduces the costs of heating and / or cooling environments.
- · Polyurethane insulation requires very little space, reducing construction costs.
- · The polyurethane foam will not yield or deform over time, which makes it an excellent long-term investment.
