Several solutions are used to ensure a house’s thermal and sound insulation. Many people now use a combination of plaster and insulation for optimal insulation. What is a plaster? How is it applied? Which insulator should I choose for a plaster?
What Is Render?
Render is a material often used in masonry to dress, protect and renovate the exterior facades of a house. Generally, it is the finishing coat or the last layer that the mason applies to the exterior façade. The rendering is a material of aesthetics but also of protection.
It protects the exterior facade of the house against possible bad weather. It also plays the function of insulation. It is an excellent thermal and phonic insulator. The plaster is ideally suited to concrete, stone, brick or plasterboard facades.
It is applied with a trowel, a special plaster roller, or a machine. The plaster must be applied in favorable weather conditions. Indeed, applying an application during the rainy period or the period of freezing is not recommended. High heat, extreme cold, and humidity are not suitable for the plaster. They can cause or lead to peeling and cracking of the plaster.
The Different Techniques for the Application of a Plaster
There are several techniques to apply a plaster. But before any application, it is necessary to ensure that the work is completed at least one month in advance. The different techniques of application of plaster are :
The technique of the projected plaster: it is generally used for big buildings. It is a swift technique that is applied with a machine;
The taloché plaster: this technique is applied with the help of a trowel or a trowel for a smooth result. It is a rather tricky technique that requires great precision.
The scraped rendering technique: It consists in projecting the rendering with a machine. Once the projection is done, the plaster is then scraped with a nail trowel or a specific rule for uniform and neat plastering;
The crushed plaster technique: It is similar to the scraped plaster technique. The only difference here is that after projection, the plaster is delicately smoothed with a trowel for a more modern look.
Which Insulator for Plaster?
For quality thermal and phonic insulation, the plaster is applied in combination with several types of insulators. The most commonly used insulating materials for plaster are :
Polystyrene is synthetic insulation, very efficient. Even if it is described for its not very ecological side, it is an insulator that is perfectly suitable for the insulation of frontage.
It is a natural insulator known for its excellent insulating properties. It ensures perfect thermal and phonic insulation of your house, but it also resists the bad weather, the parasites or wear in time. Hemp also protects against electromagnetic waves, vibrations from the subsoil, and high voltage lines.
It is a natural insulator known for its thermal and phonic insulation properties and excellent resistance to fire and bad weather.
It is a mixture of earth and straw. It is an excellent natural insulator generally used to insulate all types of houses, particularly by insulating from the outside. It is ideal for wall insulation.
Combined with plaster, wood fibers insulate a house perfectly. Wood fiber insulation is natural, environmentally friendly, and has an excellent thermal storage capacity.
With a few exceptions, natural insulation is the most effective for the exterior façade. These insulations with a plaster offer you high-quality thermal and phonic insulation.
