Types of isolation
Comfort in a house, office or commercial venue starts with the use of good materials for isolation which allows us to live satisfying and happy live.
Given its importance, we are showing you on our blog all the varieties that exist and their uses.
On this post, you will learn about most suitable products regarding our necessities: thermal isolation, sound or electricity isolation…
Let´s start by defining the main types of isolation that make our house or workplace an ideal to live or develop our daily activity.
The main types of isolation are the following:
It is used to avoid heat loss in the winter and to ensure a cold environment inside the house during the summer. The isolation is achieved by using isolating materials in the exterior walls, roof covering, floors, partition walls and holes. These materials should be porous and fibrous, capable of keeping the dry air inside some more or less airtight.
Bad isolation is a very common problem and makes it hard to achieve comfort wanted for our house, even when our installations are efficient from energetic and technical point of view.
Sound isolation is the using of sound-softening materials in a certain space, forbidding sound to get in or out of it.
We can point out two types of isolation referring to air-transmitted noise and impact-transmitted noise. It is also important to notice that the weakest link in the construction chain has a great impact in the whole sound isolation. It is, for example, very important to avoid leaks in the construction elements.
The principal function of damp-proof isolation is to become a barrier against humidity to avoid its filtration between the different elements of the construction including its foundations, external coverings, windows and doors.
It is important to use the right materials to isolate the space from humidity because it can cause severe damages to the house.
Its main objective is to avoid electricity flow.
The materials used for electric isolation keep the different conducting parts from contacting (installation`s isolation) and protect people from the electricity flow (protecting isolation).
Fire isolation is a wide variety of isolations and protection against flames, for different structures, situations and construction materials.
Isolation efficiency is a key factor; there are quite a few different materials that can be used.
In the market, we can find lots of solutions for very type of isolation, some of them are more suitable than others, depending on our goal.
We elaborated a list of the main isolating materials:
- Polyurethane foam: it works well with high temperatures, noise and humidity. It has two common application methods: spraying it through a two-component pulverization system over a surface called substratum or by straining, where both components are injected and mixed together to introduce the mixture into the holes so the product expands in it. There is no doubt, that besides being one of the best isolating materials, if combined with the right additives can achieve excellent results as noise and fire isolation.
- Mineral wool: it is an isolating material made of tangled rocky fibers, siliceous sand or basaltic rock, which forms a felt that keeps air inside. It is very light and good provides good protection against heat, noise and fire.
- Styrofoam: it is also known as XPS. It is presented as stiff foam, isolating and with thermoplastic characteristics. It is really good as a thermal isolating and can be used in humid environments or even flooded, which make it a perfect solution. It can tolerate ice and thaw cycles so it is very useful in cold climates.
- Laminated plaster sheets: it is sometimes used as isolating material but from a thermal point of view it is always used in combination with other materials, such as mineral wool or foams, in order to reach standards.
