ARBOFLEX Carrier Membrane 1m x 33m

The ARBOFLEX Liquid Carrier Membrane is a premium, polyester-reinforced roofing base layer designed for robust, multi-layer built-up roofing systems. It features high-quality SBS (Styrene-Butadiene-Styrene) modified bitumen, ensuring superior flexibility and strength. The membrane is protected with fine-grained sand on the upper layer and a self-adhesive compound coating on the bottom layer, which is covered with a removable film for ease of application.

The ARBOFELX Liquid Carrier Membrane is used above tissue-faced insulation in a warm deck roof, such as Kingspan TR27, Recticel Powerdeck F & Ecotherm Innobond. Installed with FG35 primer for a fully bonded system. We recommend ALUTRIX 600 Vapour Barrier below the tissue-faced insulation.

Chemical Resistance

ARBOFLEX® Liquid Carrier Membrane is water-resistant and stands up to watery solutions of salt, diluted non-oxidising acids, and bases. However, it should not be exposed to aliphatic and aromatic hydrocarbons, chlorine hydrocarbons, oils, and greases, as these may degrade the product.

Application Guidelines

1. Substrate Preparation: Ensure the substrate is dry, clean, and free of impurities. Prime with CARLISLE® FG35.
2. Installation: Lay out the membrane in the required direction, ensuring a 15 cm overlap on short side overlaps of 1 meter, and a 10 cm overlap for long side overlaps. Peel off the silicone release foil from the lower surface as work proceeds to bond the self-adhesive compound firmly to the substrate.
3. On Sloping Roofs: Lay the self-adhesive membrane from the bottom, perpendicular to the slope direction.
