27 bauder. co. uk System Airtech Airtech has been specifically developed to meet the demands for improved safety in the installation of modern bituminous roof systems. New self- adhesive membrane technology, superior adhesives and hot air welding all combine to eliminate the inherent dangers of naked flame and hot bitumen. Airtech is not only safer to install, but also faster, cleaner and quieter than traditional pour and roll or torch- applied bituminous systems. The system has an estimated life expectancy in excess of thirty years and is ideal for both new build and refurbishment flat roof projects. KEY FEATURES n 4.2 mm thick, self adhesive elastomeric bitumen capping sheet with hot air welding at the laps for a safety conscious solution. n Able to withstand climatic extremes and temperature differences at the edges of ice and water; stable in extreme weather conditions for temperatures ranging from - 30° C to + 100° C when tested to the following European Standards; Cold bending test ( EN 1109) and heat stability test ( EN 1110). n The system is resilient, tough, long lasting and is easily capable of withstanding foot traffic or permanent loads of up to 2000Kg/ m ² n Guaranteed for 15 years. Craigcrook Castle lies 3miles west northwest of the centre of Edinburgh and has important literary connections. The castle is a much- altered Z- plan tower house, begun c. 1542 by William Adamson, an Edinburgh merchant who was killed at the Battle of Pinkie in 1547. The Airtech System was used on the roof refurbishment of some or the extensions of the castle because of its durability and safety aspects.
