Polyurethane foam is one of the most popular insulation materials in the building industry thanks to its high thermal insulation efficiency, durability and ease of application. However, like any chemical substance, it raises questions about its impact on health and environment. Can polyurethane foam be harmful? Read on to find out!
Facts and myths about polyurethane foam
Polyurethane foam is more and more popular as a modern building insulation material. However, many myths have arisen around its use, especially regarding health safety. Let’s separate facts from concerns and check how PUR foam really works in your home.
MYTH – Polyurethane foam is harmful to people
This is not true. After application, the foam reaches its final properties within 24-72 h. During this time, the room should be well ventilated. Once this process is complete, the foam becomes chemically stable and completely safe for the occupants of the house – it doesn’t emit harmful vapours, produce dust or react with the environment. This means that you can safely stay in rooms where it has been used.
FACT – Protection and ventilation are important during foam application
During the application of foam, a chemical reaction occurs, so contractors always use appropriate protective equipment – special masks, protective suits and gloves. Good ventilation of the rooms where foam is applied is equally important. Thanks to regular ventilation, the curing process is safer, and once it is complete, the building can be used without any concerns.
MYTH – Foam releases high concentrations of formaldehyde into the air
Strict national standards clearly define safe formaldehyde emission levels for polyurethane foams. Reputable manufacturers use only certified raw materials that undergo detailed testing for health and environmental safety. Tests carried out on Polychem Systems foams have shown that formaldehyde emissions from cured foam are negligible or significantly lower than the requirements for rooms intended for permanent human occupancy.
FACT – PUR foam promotes energy efficiency
Thanks to its excellent insulating properties, it reduces heat loss in the home, which in practice means lower bills and lower CO₂ emissions into the atmosphere. It is an investment that is friendly to both the household and the environment.
MYTH – Foam deteriorates quickly and needs to be replaced often
Polyurethane foam is one of the most durable insulation solutions available on the market. It has been used in Poland for over 25 years and still retains its properties – it doesn’t settle, shrink or degrade. As a result, once PUR foam insulation has been installed, it provides long-lasting protection and comfort in the home without the need for replacement.
FACT – The source of the foam matters
Choose products from reliable manufacturers and use the services of professional teams. This ensures that the insulation will be durable, safe and effective for many years.
What to look for when choosing foam – 5 useful tips.
Although polyurethane foam is applied by a professional contractor, as a homeowner you have the right to know whether the foam applied meets all safety and quality standards. Here are a few things to look out for:
-
Certificates and compliance with standards
Make sure that the foam recommended by the contractor has the required European certificates. The foam components should be registered in the REACH system (Registration, Evaluation, Authorisation and Restriction of Chemicals). It is also important that the product has a Declaration of Performance, confirming compliance with European standards, and, in some cases, a National Institute of Hygiene certificate, which confirms safety of use. With such documents you can be sure that the foam has been thoroughly tested and meets strict quality and safety standards.
-
Safety for health and the environment
Ask the contractor if the foam used emits harmful gases after curing and complies with European environmental regulations. Polychem Systems foams always comply with these requirement so you can be certain about your family’s safety.
-
Stable composition and predictable parameters
Always use foams with a consistent composition that perform in a predictable manner. This will ensure that the insulation remains effective and durable for years to come.
-
Durability and energy savings
Good quality polyurethane foam is a lasting investment. Choose solutions from proven manufacturers, such as Polychem Systems, to make sure that the insulation will not need to be replaced and your home remains warm and energy-efficient, and your heating bills remain lower.
-
Proven source and technical support
Always use products from a reputable manufacturer. This guarantees quality, safety and technical support if you have any questions or concerns. After the work is done, your contractor should prepare Applicator’s Declaration for the investor, which includes:
- Applicator details
- Name of the foam and manufacturer
- Application parameters
