INSULATION OF MOBILE HOMES – EFFECTIVE ENERGY SAVINGS.

Only properly insulated mobile homes and mobile homes are suitable for year-round use and living in our climatic conditions. 
As thermal insulation, we use the following materials in our Super Arktik ® ORIGINAL mobile homes, WOOD, MODERN, OFFICE and HOTEL. 

1) GREY POLYSTYRENE – WALLS AND FLOOR.
Insulation with grey polystyrene (so-called graphite polystyrene) with a thickness of 10 cm brings several practical, energy and financial advantages. This type of polystyrene is a more advanced version of white EPS and is mainly known for its higher thermal insulation performance. What are the advantages of insulating a mobile home with grey polystyrene (10 cm)?

Excellent thermal insulation.
- Significantly better thermal insulation compared to white polystyrene.
- Grey EPS contains graphite, which reflects thermal radiation.
- It has approximately 20 to 25% better insulating performance than standard white EPS.
- Even at a thickness of 10 cm, you achieve a similar effect as with 12–13 cm of white polystyrene.

Savings on heating and cooling.
- Keeps heat inside during winter and protects against overheating in summer.
- Due to lower thermal conductivity, the need for heating in winter and air conditioning in summer is reduced. This means lower energy costs.
- Fewer temperature fluctuations inside the interior. A more stable and pleasant indoor environment compared to insulation with white polystyrene.

Lower load on the structure.
- EPS is a lightweight material. It does not place stress on the mobile home structure.

Improved acoustics.
- Although EPS is not a top-tier sound insulator, it helps reduce noise from the external environment (e.g. wind, rain).

Technical data of grey polystyrene (10 cm)
- Thermal resistance (approx.) R = 3.03 m²K/W
- Lambda (thermal conductivity coefficient) 0.031 W/mK
- Compared to white EPS 20 to 25% more efficient

2) MINERAL WOOL – CEILING.
Insulating the roof of a mobile home with mineral wool with a thickness of 10 cm is a very effective solution in terms of thermal comfort, sound insulation and fire safety. What are the advantages of insulating the roof with mineral wool?

Thermal insulation. Protection in winter and summer.
- A thickness of 10 cm of mineral wool (λ ≈ 0.035–0.039 W/m·K) provides thermal resistance R ≈ 2.6–2.9 m²K/W.
- The roof is the most exposed surface. The most heat escapes through the roof in winter and the most heat penetrates inside in summer.
- Mineral wool also has the advantage of thermal accumulation. It slows down interior overheating during heat waves (better than polystyrene).

Increased acoustic comfort.
- Mineral wool provides excellent sound insulation.
- It reduces noise from rain and wind, which is a common issue with metal roofs on mobile homes.
- It reduces external noise from the surroundings (e.g. roads, neighbors, nature).
- The overall sense of comfort inside the interior is significantly improved.

Fire safety.
- Mineral wool is a non-combustible material (class A1). It does not burn, smoke, or drip.
- In the event of a fire, it slows the spread of flames, which is a major advantage.

Vapour permeability of the roof.
- Mineral wool allows water vapor to pass through. In combination with a proper roof structure, it enables moisture to escape from the roof space.
- The risk of condensation, dampness and mold formation is minimized.

Lightweight yet stable insulation.
- Although the wool is lightweight, it is dimensionally stable, does not change volume and does not settle over time. It is ideal for roof structures of mobile homes.

Summary of advantages:
- Thermal insulation: protection against winter heat loss and summer overheating.
- Sound insulation: reduces rain, wind and external noise.
- Fire safety: non-combustible material, high level of safety.
- Vapour permeability: reduces the risk of mold and moisture.
- Stability and durability: does not deform, does not settle.
- Eco-friendliness: natural material.
