Differences between Rock Wool and Polyurethane Insulating Panel for our Restaurant

The difference between a polyurethane insulating panel and a panel with a rock wool core lies in the formation of the core of each of the panels.

In this article, we are going to discuss the differences in uses and needs between these two types of Sandwich Panels.

Polyurethane Vs Rock Wool Insulating

The polyurethane insulating core is a foam formed by the reaction of isocyanate and polyol (polyester or polyethylene glycol). A catalyst is added to this mixture in order to improve the reaction and the inclusion of other additives that allow changing characteristics of this material.

Rock wool is a material made from rocks of volcanic origin. It has been used as an excellent thermal insulator, as an insulator against fire, and in turn as an acoustic insulator. Due to its fibrous and multidirectional internal structure, it hardly contains any air inside. They are commonly used in the residential sector but also in the construction of industrial warehouses with insulation requirements, with cold storage or freezing chamber installations.

Differences between Rock Wool and Polyurethanes: Thermal Insulation

It is important to know that we need to know a series of previous characteristics to assess its capabilities.

  • Thermal insulation value
  • The behavior of materials against fire
  • Acoustic Insulation Capacity
  • On-site handling and installation

Let’s take a closer look at these capabilities.

Thermal insulation value:  PUR and PIR panels have a greater thermal insulation capacity compared to rock wool. At the same thickness of both panels, the thermal insulation capacity is higher because the polyurethane insulates more. Then, a 50 mm thick polyurethane panel insulates thermally like a rock wool panel about 80/100 mm thick.

The behavior of materials against fire.  Polyurethane, being an organic compound, can tend to feed the flames.
The rock wool, made up of inorganic elements, does not contribute at all to the spread of fire, which is especially important in industrial cold-storage installations. This implies that, if we need to separate fire loads by prescription, with the absence of flame for up to 240 minutes, the Rock Wool panel will withstand long periods of time without causing fire, which facilitates the compartmentalization of storage sectors of goods.

Sound insulation capacity.  One of the most important advantages of a rock wool panel is its noise reduction capacity since rock wool fibers are one of the best destroyers of acoustic waves and significantly reduce their intensity. The Polyurethane panel does not reveal itself against the acoustic insulation to an insignificant extent

Handling and installation on site. Here, in terms of ease of assembly, both panels have similar behavior due to their own construction, although the rock wool panel is heavier than a polyurethane panel and, therefore, requires experience and greater technical means for handling and installation.

We hired American Walk-In Coolers to construct our C1D1 Extraction Labs with the best insulation to build our restaurant’s walk in cooler.



9 Benefits of Swimming

In this article we present 9 benefits of swimming for both children and adults.

All sports have benefits. However, each one provides different advantages that the others do not.

Swimming is a sport that, due to the environment in which it takes place, has many differentiators compared to most sports.

1. Develop coordination

Swimming works with many body movements at once. To move in the water you must move your arms and legs, while also paying attention to floating and breathing.

In order to move forward, all the movements are carried out simultaneously and with rhythm, for which you acquire great coordination skills.

2. Work of different muscle groups simultaneously

In the water we must exert more force to move due to the density of the water, and therefore it is necessary to use a good part of our body to move.

This allows many muscle groups to be worked in the water. And since all the exercise takes place simultaneously, it is possible to develop the muscles with little exercise time.

Some of the muscles that are worked in swimming are the following:

  • In legs: quadriceps, hamstrings and tibialis.
  • In arms: biceps and triceps.
  • In forearm and hand: supinators and pronators.
  • In back: dorsal, trapezius and deltoids.
  • In neck: sternocleidomastoid.
  • pectorals
  • ABS.

3. Increased lung capacity and improvement of the respiratory system

Because swimming completely requires proper breathing, both to float and to submerge the head, the respiratory system is strengthened by this sport.

To be able to float, it is necessary to know how to properly inflate the lungs, and to be able to swim with your head underwater, it is necessary to learn to swim with rhythm and optimize the use of air.

Swimming is good for people who have respiratory illnesses, including those caused by smoking or being in polluted environments.

4. Improved circulation and cardiovascular system

For the cardiovascular system, there are also many benefits offered by swimming.

  • Improves oxygen consumption.
  • Decreases heart rate.
  • Create resistance.
  • Regulates blood pressure.

All this is thanks to the fact that the exercise is carried out in an aquatic environment, which has several advantages.

The body stays cool while in the water, plus you are in a horizontal position for most swimming exercises. These two things make it easier for the system to circulate the blood, because the blood can be evenly distributed in the body without much strain on the heart.

Because being in the water puts less strain on the heart, it can tolerate more physical activity.

5. Stress reduction

Exercise in general is a stress reducer, because through physical activity the blood in our brain circulates more efficiently, in addition to the fact that it produces substances such as serotonin, dopamine and endorphins, which are responsible for the feeling of well-being and happiness.

But in addition to the benefits of exercise in general, there is the fact that swimming is done in water. Being in the water, in addition to being refreshing, reduces muscle tension, as well as heart and respiratory rates, which is beneficial for keeping us in a state of relaxation that remains even hours after being in the pool.

6. Improved memory, focus and mental clarity

When we swim, because we are using many parts of our body in a coordinated way and because we are in a different environment from our daily life, our brain creates multiple mental associations and therefore generates new neural connections.

When we are swimming, in addition, we are mostly concentrated thanks to the fact that our body has to master skills that it only practices in the water.

Due to the new neural connections and concentration and coordination skills that develop in the water, our brains have the potential to improve mental clarity and focus in our daily activities, as well as memory.

7. Prevents and treats injuries

Although swimming involves greater physical effort due to the force required to move, it is a very low impact sport. This means that it is unlikely to cause any injury or damage to the joints, bones, tendons or ligaments.

But in addition to the fact that it is unlikely to cause any type of injury, swimming can also prevent and serve as a treatment in case you do have one. Some doctors advise their patients to walk in the water or swim for injuries to the lower extremities (such as ankles or knees).

In any of the cases, if you have an injury, it is the doctor who has to prescribe swimming as a therapeutic activity.

8. Eliminate fears and fears

Learning to swim is one of the activities that generates great fear for many people. This is because the body has to adapt to an environment that it does not know, and our brain activates an alert because it faces new situations.

However, to overcome fears, the most useful thing is to face what produces them.

Because for some people the fear of water is very great, once they face it, it is easier for them to face other fears in their daily lives.

9. Suitable for everyone

As it is a low-impact sport, unlike many sports, swimming is suitable for all types of people. From babies to older adults, as well as people with disabilities or people undergoing medical treatment, they can practice it.

Swimming does not represent high wear on the joints and is kind to the heart, which is why it even serves as therapy for the treatment of some physical ailments.

Hiking Safety Tips

Walking is part of our nonverbal communication, and the way we do it says a lot about us. A sad person can be noticed just by walking, just like an upset or suffocated person.

However, when we want to project a good personal image, we must walk safely to mark territory, they can trust us and look attractive.

For that reason, I am going to give you the 3 essential tips to be able to walk safely and project a correct personal image:

The Posture

When you stand still and walk, your posture must be correct to show confidence. The correct way is to make your shoulders back, straight, you could even squeeze your abdomen.

Do not slouch, because you will look exhausted and very insecure.

The View

This is a very important point, because if it is not the right one you can leave a wrong perception. It should not be down, because it shows a lot of insecurity, nor up because it shows haughtiness, or it would look very fake, and looking too confident denotes insecurity.

The gaze should be straight ahead. Once you have your shoulders back, you just have to look straight ahead, with a soft, warm and friendly look.

The Walking

This is not a runway walking class; however, when you want to demonstrate security, you should not throw your feet forward, as if you do not have control over them.

You should also not walk too upright and throw your chest forward with your arms half bent, because you would only show that you want to appear to be safe when in reality you are not.

The correct walk should be with the shoulders back, chest and feet in a straight line without seeming exaggerated, accompanied by a friendly look and if possible a smile when you see a person.
