Thermal insulation is one of the most prominent features of sandwich panels, but how many degrees can it really insulate?
Thermal Insulation Capacity
The sandwich panel, thanks to its insulating core, can reduce heat transfer in a building by several degrees, depending on its thickness and material. Generally speaking, a sandwich panel with a polyurethane core can provide insulation that allows a temperature difference of up to 20 degrees Celsius between inside and outside. This means that on a hot summer day, if it is 35°C outside, the inside could be kept at 15°C with the help of air conditioning systems, or around 25°C without them.
Factors Influencing Isolation
- Core Thickness: The thicker the core, the greater the insulation capacity. Thicker panels are ideal for extreme climates.
- Core Material: Polyurethane and rock wool cores are the most efficient. Rock wool also provides acoustic benefits.
- Environmental Conditions: Factors such as direct sun exposure, humidity and ventilation also affect insulation efficiency.
Benefits of Good Insulation
- Energy Saving: Reduces the need for heating in winter and air conditioning in summer, which translates into lower energy bills.
- Interior Comfort: Maintains a more constant interior temperature, increasing occupant comfort.
- Sustainability: Contributes to reducing the building’s carbon footprint by reducing energy consumption.
Conclusion
Sandwich panel is an effective insulation solution that can make a big difference in the thermal efficiency of a building. Choosing the right panel in terms of thickness and material is key to maximizing its benefits.
