Double wall polycarbonate is a popular material choice for applications such as greenhouse roofing, skylights, and patio covers. It offers excellent durability, transparency, and thermal insulation properties. When it comes to insulation, one important value to consider is the R-value. R-value is a measure of a material’s thermal resistance – the higher the R-value, the better the insulation. However, determining the exact R-value of double wall polycarbonate can be a bit challenging due to various factors.
Finding the R-value
Double wall polycarbonate is a multi-layered material with air pockets trapped between the layers. These air pockets provide insulation by slowing down the heat transfer through convection. However, the R-value of double wall polycarbonate can vary based on factors like the thickness of the material, the size and structure of the air pockets, and the surface treatment of the panels.
It is important to note that the R-value of double wall polycarbonate is not as high as some other insulation materials like foam insulation or fiberglass. Typically, the R-value of double wall polycarbonate ranges from 1.42 to 1.89 per inch of thickness, which is lower compared to traditional insulation materials. However, the unique properties of double wall polycarbonate, such as its light weight, transparency, and durability, make it an attractive choice for many applications.
What is the R-value of double wall polycarbonate?

Does the color of double wall polycarbonate affect its insulation properties?
The color of double wall polycarbonate may influence its solar heat gain properties, but it has minimal impact on its insulation performance.
Can double wall polycarbonate be used for sound insulation?
Double wall polycarbonate provides some level of sound insulation due to its multi-layered structure, but it may not be as effective as specialized soundproofing materials.
Is double wall polycarbonate resistant to condensation?
Double wall polycarbonate panels with proper installation and sealing can minimize condensation. However, in high humidity environments, some condensation may still occur.
Is double wall polycarbonate resistant to UV radiation?
Yes, double wall polycarbonate is typically treated with UV protection to prevent yellowing and degradation caused by prolonged exposure to sunlight.
Can the R-value of double wall polycarbonate deteriorate over time?
The R-value of double wall polycarbonate is is not expected to deteriorate significantly over time as long as the material remains intact and is properly maintained.
Is double wall polycarbonate a sustainable insulation option?
Double wall polycarbonate is a durable and long-lasting material, which can contribute to sustainability goals. Additionally, it can reduce the need for artificial lighting due to its high transparency, leading to energy savings.
In Conclusion
While the R-value of double wall polycarbonate may not be as high as some other insulation materials, it offers unique benefits such as transparency, durability, and light weight. The actual R-value of double wall polycarbonate can vary depending on various factors, so it is advisable to consult with manufacturers or experts to determine the most suitable insulation solution for your specific needs.
