Hot melt bitumen membrane roofing and waterproofing system.
Application
- Waterproofing layer in protected flat roofs (including zero fall), inverted roofs, and blue roof specifications, in combination with a storm water attenuation system.
- Suitable for community and amenity, education, health, hotel and leisure, industrial, mixed-use, offices, utilities, and retail applications.
Description
Crafted with meticulous attention to detail, the hot melt aspect of the IKO Permatec LI Inverted Roof System arrives at your site in fully dispersible 12 kg blocks. This ensures ease of handling and installation efficiency. The standard inverted roof build-up is a fully bonded system, where every element seamlessly integrates to create a robust protective barrier. With IKO Permatec LI, every layer works cohesively, ensuring sound structural integrity and weatherproofing capabilities. Exposed detailing is made UV stable through the application of the IKO Permaguard-M Torch-On Capsheet.
Key benefits to your project:
- Achieves over 50% lower embodied carbon with the IKO Permatec LI membrane.
- BBA approved.
- Less waste to control and dispose of meaning zero waste packaging.
- Long-lasting, durable waterproofing.
- Simple system – easy specification.
- Tough and resistant to impact damage because of its high tensile strength.
- Easily recyclable.
- Excellent low temperature flexibility.
- Outstanding durability – lasts for the design time of the building.
- Rapid setting.
- Backed with a 25 year guarantee.

Type | IKO enertherm XPS insulation board.Guidance for specification option: Available in thicknesses from 50–220 mm. Consult manufacturer and insert requirements. |
Water control layer | IKO enertherm water control layer. |
Drainage layer | Not required. Required. Guidance for specification option: For roof garden applications. Consult manufacturer and insert requirements. |
Flashings and detail work | Not required. IKO PermaFLASH-D150. Guidance for specification option: A nominal 1.25 mm thick flexible bitumen EPDM polymer detailing sheet. A reinforcement layer of PermaFLASH-D150 should be applied prior to applying the PermaTEC membrane at all non-monolithic changes in substrate materials, at structural/shrinkage cracks between 3 and 6 mm wide, at structural joints between 6 and 12 mm wide and where minor movement may occur. IKO PermaFLASH-D500. Guidance for specification option: A flexible bitumen EPDM polymer detailing sheet, installed as a reinforcement layer around rainwater outlets. IKO PermaFLASH-UN. Guidance for specification option: At structural movement joints up to 25 mm (maximum 50% total movement), PermaFLASH-UN reinforcement must be installed fully bonded in hot Permatec compound centrally over the movement joint. At structural movement joints between 12 and 50 mm (maximum 50% total movement), a proprietary joint system must be installed. Consult manufacturer for suitable products. |
Upstand | Exposed upstand details: IKO PermaGUARD-M Torch On (T-O) protection layer. Guidance for specification option: A protection layer to PermaTEC on exposed upstand details. |
