1. REF: FRF-TDS/0379/2023 DATE: 28 March 2023 Fujairah Rockwool Slabs Unfaced Packed in Black Poly Bag SXXX Thickness: 50 mm Density: 30 kg/m 3 Fujairah Rockwool slabs conformi ng to ASTM C-612 and equivalent BS-3958 Part 5 are designed for thermal and acoustic insulati on of flat or slightly curved surfaces. These slabs are produced from long, non-combustibl e resin bonded fibers. They are easy to cu t, fit and handle. The robust fibers in the slabs combine high levels o f thermal efficiency and acousti c absorption. Applications Designed for a wide range of app lications at bot h high and low service temperat ures. It can be used on both flat and slight ly curved surfaces for thermal and acous tic insulation. They are also suitable for thermal insulation of ducts , tanks, large ve ssels, cavity w alls, curtain walls and sandwich panels. Standard Delivery Available in standard width o f 600 mm and lengt h of 1200 mm. Other sizes are available upon request. Service Temperature Plain Rockwool Insulation has a s ervice temperature of 780°C wh en tested in accordance with DIN 52271 for 80mm thickness and 100 kg/m 3 density. However there is possible deviation for lowe r densities and with facings . The user is advised that it is possible that the maximum use te mperature of facings and adhesives is lower than the maximum use tem perature of the insulation. The u ser shall ensure that sufficient thickness shall be installed so none of these accessory items ( facings and adhesiv es) are exposed to temperatures above their maximum use temperature. Compatibility Compatible with all other forms of material with which it is li kely to come in contact in normal industrial and building applications.

2. Fire Safety Rockwool Insulation alone is non- combustible when tested in acc ordance with BS-476: Part 4 1970 and ASTM E-136. Class A, when tested in accordance ASTM E – 84. Thermal Conductivity Fujairah Rockwool products show r emarkably low thermal conducti vity values with ty pical figures in accordance with BS 874, equival ent ASTM C 177/C 518. We have te st reports at 35°C mean temperature for 40kg/m 3 and 70kg/m 3 densities.
