Using insulation blankets between purlins and roof sheets, with the help of insulation spacer brackets, is a common practice in construction to enhance thermal insulation and energy efficiency in buildings. Here’s how the process typically works:
Selection of Insulation Blanket: First, architects or building designers specify the appropriate insulation material based on factors such as climate, building codes, and energy efficiency goals. Insulation blankets are often made of materials like fiberglass, mineral wool, or foam board, each with its own thermal resistance properties (R-value).
Installation of Insulation Spacer Brackets: Insulation spacer brackets are installed onto the purlins, which are the horizontal structural members in the roof framework. These brackets create a space between the purlins and the roof sheets, allowing for the insertion of insulation blankets.
Placement of Insulation Blankets: The insulation blankets are then laid out between the purlins, fitting snugly within the space created by the insulation spacer brackets. The thickness of the insulation blankets may vary depending on the desired level of thermal insulation.
Securing Roof Sheets: Once the insulation blankets are in place, the roof sheets are installed on top, fastened securely to the purlins. The insulation spacer brackets help maintain the integrity of the insulation layer and prevent compression, ensuring optimal thermal performance.
Sealing and Finishing: Finally, any gaps or seams between the insulation blankets and roof sheets are sealed to prevent air leakage and moisture infiltration. Proper sealing is essential for maximizing the effectiveness of the insulation and maintaining the building’s energy efficiency.
By incorporating insulation blankets between purlins and roof sheets using insulation spacer brackets, buildings can benefit from improved thermal insulation, reduced heat transfer, and lower energy consumption for heating and cooling. This approach contributes to a more comfortable indoor environment and helps to meet energy efficiency standards and sustainability goals.
