Celotex Energy-Lok EL3000

Provides a quick and easy method of achieving effective thermal insulation in flat roofing structures. With coated glass tissue facings, EL3000 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and a low global warming impact.

Advantages

With Celotex EL3000, you are specifying insulation board that:

Is designed for use in a variety of flat roof systems
Achieves U-values with minimum thickness
Is strong and durable
Is rot proof
Is dimensionally stable and unaffected by temperature cycles
Is easy to cut and shape
Requires minimum number of fixings
Comes in a range of thicknesses from 50-150mm
Is available in two different sizes: 1200mm x 600mm and 1200mm x 2400mm
Note: EL3050 available in 600mm length only

Applications

The facers are suitable for bonding in the following flat roofing applications:

Perforated facer

• Mastic asphalt

• Bituminous built-up roofing systems

Unperforated facer

• Single-ply, fully adhered flat roof systems
• Single-ply, mechanically fixed flat roof systems
• Self-adhesive membranes
• Liquid-applied membranes

Installation Guidelines

Built-up flat roofing applications

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.

Single-ply membrane flat roofing applications

Use Celotex EL3000 high performance insulation in either mechanically fixed or fully adhered single-ply flat roofing applications. The unperforated facer is suitable for single-ply fully adhered roof systems, self adhesive membranes and liquid-applied membranes.

Alternatively, use Celotex TA4000 high performance insulation in mechanically fixed, single-ply flat roofing systems where the higher compressive strength of the board gives improved resistance to site traffic during installation.

When designing a flat roof using Celotex EL3000 or TA4000 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.
