What is Polystyrene and Why is it Chosen?
Polystyrene is a popular material for wall insulation. It is lightweight, easy to install, and effectively insulates against the cold.
It has a low thermal conductivity coefficient. This helps retain heat in rooms. According to experts, well-insulated walls can reduce heating costs by 20-30%.
Properties of Polystyrene
Polystyrene is very dense, making it strong and durable. It does not absorb moisture, which increases its lifespan.
Advantages of Insulating with this Material
Insulating with polystyrene has many advantages. These include affordability, ease of installation, and effectiveness. In Ukraine, polystyrene accounts for about 32% of the insulation market.
For external insulation, it is better to use polystyrene in areas with high loads. More information about facade insulation can be found on the website about facade insulation.
Preparation for Wall Insulation
Before insulating walls from the inside, it is important to prepare well. At the beginning, it is necessary to assess the condition of the walls and select the necessary tools and materials. It is also important to prepare the room for work.
Before starting, you need to check how the walls are made and how many there are. This will help determine how much polystyrene is needed. You also need to clear the room of furniture and other items.
For the work, you will need polystyrene, dowels, glue, and other materials. Don’t forget about protective gear, such as gloves and a mask, to avoid inhaling dust.
Cleaning the walls from old paint and putty is important for preparation. It is also necessary to check the walls for cracks and other damage. Proper preparation will ensure successful work and a long lifespan for the insulation.
Insulation Process: Step-by-Step Instructions
Insulating walls from the inside with polystyrene foam helps reduce heat loss. This is the main reason for high energy costs. The process includes several important steps to achieve the best results.
First, you need to calculate how much material is needed. This depends on the size of the walls and the thickness of the polystyrene. Then, clean the walls of dirt and old paints.
Now you can start installing polystyrene. Apply glue to the walls and to the polystyrene. Then stick them to the walls. Insulation requires attention and precision, but the results will be valuable.
When insulating walls from the inside, polystyrene with a density of 15 is used. For facades, it is better to use densities of 25 or 35. The amount of glue depends on the type of glue and the size of the walls.
How to Properly Choose Polystyrene?
When choosing polystyrene for wall insulation, it is important to pay attention to several key factors. The density and thickness of the material are significant for quality. For interior walls, it is better to use polystyrene with a thickness of 5 cm.
The qualification of polystyrene is also important. Manufacturers must meet standards to ensure high product quality. For example, extruded polystyrene can last up to 30 years, making it ideal for insulation.
When choosing polystyrene manufacturers, it is important to consider their reputation and experience. Manufacturers with quality certificates and production standards guarantee high product quality. Choosing high-quality material for wall insulation is essential for creating a comfortable home.
Internal Insulation: Important Details
When insulating walls from the inside, it is important to pay attention to several details. The method of installing polystyrene is key. You can use glue or fasteners. Both methods have their pros and cons.
Processing the seams between the boards is also important. It helps avoid moisture condensation. For this, waterproof membranes or vapor barrier films are used.
Insulating walls from the inside can reduce energy consumption. But for this, it is necessary to properly perform the installation of polystyrene.
Additional Advantages of Insulation
Insulating walls from the inside with polystyrene foam has many benefits. First of all, it leads to significant savings on heating. It can reach 30% due to reduced energy costs.
Another major advantage is the improvement of comfort in the room. Insulating walls from the inside with polystyrene helps retain heat. This makes the room more comfortable for living.
Additionally, the value of real estate can increase by 5-10% when sold or rented. This is due to the insulation.
Below is a table comparing the advantages of insulating walls from the inside with polystyrene foam with other materials:
| Material | Savings on Heating | Comfort Improvement |
|---|---|---|
| Polystyrene | up to 30% | higher by 40% |
| Mineral Wool | up to 25% | higher by 30% |
As seen from the table, insulating walls from the inside with polystyrene foam has many advantages. This makes it popular among homeowners. If you want to improve comfort in your home and save on heating, this can be a good option.
Common Mistakes to Avoid During Insulation
Insulating walls from the inside with polystyrene foam can be complex. Incorrect material selection can reduce insulation by 15-25%. Ignoring preparation can lead to delamination of materials, increasing costs.
Incorrect installation techniques can lead to cracks on the facade after the first season. Insulating during precipitation can worsen the quality of glue and paint. It is important to consider the thickness of the insulation, the preparation of the base, and the correct application of glue.
- The thickness of the insulation should be at least 60% of the coverage of polystyrene or mineral wool with glue to ensure proper adhesion.
- Lack of base preparation can lead to delamination of materials, which can increase costs for reworking the facade.
- Incorrect application of glue on the reinforcing mesh can lead to cracks on the facade after the first season.
Avoiding these mistakes will ensure effective and quality insulation. This reduces heating costs and increases comfort. It is important to choose the right material, prepare the base, and apply glue correctly.
Care for Insulated Walls
Insulating walls from the inside with polystyrene foam requires regular maintenance. This ensures long-term effectiveness of thermal insulation. Proper care includes checking the condition of the polystyrene, repairs, and maintenance.
The condition of the polystyrene should be checked regularly. A visual inspection helps identify cracks and deformations. In case of damage, repairs should be carried out.
Repairs include replacing damaged boards and restoring insulation. This helps ensure the effectiveness of thermal insulation. Proper repairs prevent additional heating costs.
Regular care for insulated walls is important. It includes checking the condition, repairs, and maintenance. Proper care ensures energy savings and comfort.
- Checking the condition of the polystyrene
- Repair and maintenance of insulation
- Replacing damaged polystyrene boards
- Restoring waterproofing and vapor barrier
Caring for wall insulation is important for effectiveness. It ensures energy savings and comfort. Insulating with polystyrene reduces heating costs.
Conclusions: Why You Should Insulate Walls with Polystyrene
Insulating walls with polystyrene is an effective way to increase the energy efficiency of your home. Polystyrene has low thermal conductivity. This significantly reduces heat loss through walls.
This method helps save on heating and air conditioning. It is very beneficial for your budget.
The cost of insulation with polystyrene can be lower than external insulation. This is especially important if you do not want to change the appearance of the building. Insulating from the inside can be a very effective and economical solution.
