External Thermal Insulation Lamella 
Catalog Number NBHIM-7863
Size (L×W) 1200 × 150 mm, 1200 × 200 mm, 1200 × 250 mm
| Description | The External Thermal Insulation Lamella is tailored for use in external thermal insulation composite systems and dry-hanging curtain wall thermal insulation systems as a fire-resistant insulation material. It can also be used in combination with other insulation materials, such as EPS, XPS, and PU, which have combustion performance ratings inferior to Class-A, to enhance the overall fire performance of the system. Additionally, it can be applied to cold ceilings for fire protection, thermal insulation, and sound absorption. This lamella is versatile and suitable for both new and expansion projects, as well as retrofitting projects of existing buildings. |
| Application | Rock wool lamella has good flatness, small size, light weight, very high compressive and tensile strength, and is also convenient in construction, all make it perfect for places such as high-rise buildings or balconies where high wind load resistance and impact resistance are required. Anchors with washer diameter no smaller than 140mm are recommended. |
