What is The Difference Between Rockwool Insulated Panels And PUR?

Rockwool Insulation
This blog will describe every detail about the differences between Rockwool insulation panels and PUR. We will first explain the differences in the insulating core. We will then go into detail and discuss the differences between Rockwool and PUR sandwich panels.
The insulating core is what makes a panel different from a rock wool insulated panel. Rigid polyurethane foam, also known as PUR or PU, is the insulating core for a polyurethane panel.
Its place between the metal supports in production. The foam reacts with air to form a solid and glue the plates together. This creates a monolithic product that has a high insulation value.
Rigid polyurethane insulation products (PUR) are lightweight and highly effective. Many can bond to all materials.
A wide range of products is possible because of its low thermal conductivity, high strength-to-weight ratio, and excellent manufacturing flexibility. PUR insulation products are the best choice for most construction insulation applications.
Rockwool panels make up of rock wool. Also known as mineral wool, it is their insulation core. The Rockwool glues between two sheets to form a monolithic product.
Any fibrous material made by drawing a molten rock, spinning, or mineral materials, such as ceramics, calls mineral wool. Mineral wool can uses as thermal insulation (structural insulation or pipe insulation), soundproofing, filtration, and hydroponic growth medium.

What are the differences between these kinds of insulated panels?

  • Insulation value
  • Fire Behaviour;
  • Sound isolation

Insulation Value:

Polyurethane has a higher insulation value than rock wool. What does this mean? It means that the insulation thickness is the same as the polyurethane isolation, but the acoustic insulation panel’s thickness is more significant. A 50 mm thick polyurethane insulation panel acts as a Rockwool panel but is denser than an 80 mm panel.

Fire Behaviour:

The organic compound polyurethane images, which can ignite the flames to a greater or lesser extent, call organic compounds.
Rockwool makeup of inorganic elements that do not contribute to spreading the fire. What does this all mean? This means that a rock wool panel requires if a product needs that can withstand fire for an hour, two hours, or three hours.

Sound Insulation:

A Rockwool panel’s core benefit is the contribution in a superior manner to noise reduction. The rock wool fibers reduce the intensity and break down the acoustic waves.

Manipulation and Installation in Place:

These acoustic ceiling insulation differences can attribute to the fact that rock wool weighs more than polyurethane, making it easier to handle and requiring more skill for installation.

Rockwool: Cavity Wall Insulation to Volcano Insulation:

Did you ever consider what insulation material you should use for your home? You’ll please to know that there are many options for insulation materials.
Rockwool is one such insulation material. Many homes have been insulated with Rockwool, especially Rockwool cavity wall insulation.
To ensure that your Rockwool wall insulation is the best, there are some things you need to know. This article will explain everything you need to know about Rockwool cavity walls insulation.
Rockwool is a common material used for cavity wall insulation. Our Sound Shield is made up of Rockwool. It is crucial to consider the potential benefits and drawbacks of Rockwool cavity wall insulation before you decide.


Rockwool cavity wall insulation can recycles from volcanic rock. This makes insulation a durable, and sustainable solution.
Thermal performance: Walls can allow for heat transfer of up to 25%-30%. Rockwool insulation’s fibers create a thermal barrier that protects your home from temperature fluctuations. The thermal performance of Rockwool cavity wall insulation improves, making your home more efficient and energy-efficient.
Acoustic board noise-reducing properties are what set it apart from other cavity wall insulation. The Rockwool is quiet and can keep noise from neighbors or create a peaceful area in your home.
The Rockwool is fire-resistant: Rockwool, made from volcanic rock, is fire-safe. Rockwool won’t catch fire or spread in the event of a fire at home.

Rockwool Wall Insulation offers incredible benefits:

  • Fire and noise reduction
  • Energy Efficiency and Thermal Regulation
  • Environmentally friendly material

Noise Reduction and Fire Resistant:

Rockwool Flexi is made from volcanic rock and provides excellent fire-safe insulation for existing and new homes.
This affordable insulator offers peace of mind for all household members and is great for keeping noise out of the homes of shift workers, children sleeping at night, and people who live in noisy neighborhoods.

Energy Efficiency and Thermal Regulation:

Even if the ceiling is well insulated, your house will lose and gain 30-50% of its heat through walls. Rockwool can reduce this effect by retaining up to 85% warmth and coolness inside your home. It is also a sustainable way of reducing energy costs.

Environmentally Friendly Material:

Rockwool wall insulation makes from encourages sustainability, environmentally-friendly volcanic rock, and durability. Fiberglass insulation products know to attract mold and contain harsh fibers that can compare to asbestos.
They can also be challenging to work with. Cellulose insulation can be highly flammable, which makes it an excellent breeding ground for moisture and pests.
Rockwool, rigid, full-fill insulation fits your walls and can use for renovations or new construction. It is also available in various thicknesses.


This method of installation is usually done from the outside of your home. Drilling does through the brick joints, leaving a hole of approximately 50mm.
These holes can fill with mortar and be re-bricked to make your home look brand new. You now have a better understanding of Rockwool and can explore the various options for cavity wall insulation in your home.
Industrial insulation is technologically advanced and can reduce the risks of environmental factors like fire, water, and temperature extremes. It also helps to cut workplace risks such as noise and air quality.
Incorporating industrial Rockwool insulation in a workplace reduces the risk and creates safer, healthier working conditions for workers and their families.
