Use Celotex EL3000 high performance insulation in built-up roofing applications, including hot-applied bituminous and mastic asphalt waterproofing systems. The perforated facer is suitable for bonding in mastic asphalt applications and hot bituminous built-up roofing systems.
When designing a flat roof using Celotex EL3000 boards, three basic principles apply:
1. Design to a fall of 1:80, 1:60 or 1:40 as appropriate to the weathering system, type of deck and construction tolerances.
2. Have due regard for the use and design of the building and the need to ensure that the design will not allow a build up of moisture below the waterproofing membrane.
3. Provide adequate protection for both insulation and waterproofing if significant foot traffic is expected either during or after the completion of the roof.
