Lambdaboard OVER PURLIN 2012 - D&D Roof Insulation

1 over PURLIN . Lambdaboard , a polyisocyanurate cored Insulation is a over PURLIN ROOF LININGS: hydrocarbon-based blowing agent which has zero Ozone Depletion Potential (ODP) and complies with Kyoto Protocol Lambdaboard can be installed above the purlins below regarding Global Warming Potential (GWP). Lambdaboard the roof sheeting for most economical installation. Based on Insulation is the answer to HCFC and HFC free Insulation 25mm board Lambdaboard can span up to 1800mm without Long Term R-value support on the longitudinal joins. Boards butt joined over the Recyclable PURLIN , lengths should be ordered to span across a minimum of 3. environmental green choice. PURLIN spacing's. Roof sheeting is then fastened directly through Highest R-value per 25mm of thickness.

2 Board into PURLIN (Figure 1). For PURLIN spacing's above maximum Moisture resistant, water repellent. span ability, H or T sections are recommended to be used to Resistant to solvents used in construction adhesives. Excellent dimensional stability. be used on the PURLIN where the boards butt joins to prevent movement while laying down the roof sheeting. When using Service temperature range from -30 C to 140 C. H or T sections it is recommended that the sections be pop Thermosetting material does not soften or melt riveted to the PURLIN to keep in place. H sections to be used for Lengths are manufactured to order, Standard width of 20 and 25mm, for thicker boards the T section is only required. 1220mm. TM.

3 over PURLIN . Excellent Dimensional Stability Lambdaboard has a high compressive strength therefore the board will not compress over the PURLIN and create thermal bridging. Being thermosetting foam Lambdaboard has great dimensional stability Temperature cycling encountered in over PURLIN applications does not a ect Lambdaboard properties such as dimensional stability and thermal performance and experienced on common roof sheeting where temperatures Roof cladding can and do exceed 100C. LAMBDABAORD will NOT soften or melt at these temperatures Lambdaboard R-value Performance Gutter Steel portals Lambdaboard has the highest R-value per 25mm, therefore Side cladding the design U-value of the roof Insulation system can be Lambdaboard achieved with a minimum thickness of Insulation .

4 This in turn allows the overall footprint of the building to decrease and reduces the cost of construction. Additionally, the thinner Roof cladding Insulation helps the mechanical strength and design of the roof structure.
