ARBO® FR-RS is a high performance, self-adhesive EPDM alternative which has a Class B reaction to fire classification. This innovative ARBO® FR-RS is manufactured using a high quality elastomeric modified butyl tape.

ARBO® FR-RS achieves a Class B-s1-d0 reaction to fire classification and creates an airtight and fire safe detail around windows, door frames and structural openings.

For ease of installation, it comes with a split release liner on the self-adhesive side to assist with installation onto the substrates. The split is positioned 30 mm from the edge.

Features and benefits:

Permanent weathertight, waterproofing.
Class B-s1-d0 reaction to fire classification.
Airtight.
Multiple application surfaces.
Vapour impermeable joint sealing.
The adhesive bonding strengthens over time.

The self-adhesive properties of FR-RS require the product to be 'squashed' during application. This means the product should be rollered using a silicone hand roller, and a 'penny roller' for internal corner details. This ensures excellent adhesion onto the substrate with the FR-RS following the profile of the substrate. Where adhering to an aggregate rich (rough) concrete surface this is particularly important to ensure a fully watertight seal is achieved.

The self-adhesive properties of FR-RS are fully activated by pressure, therefore firm application is an essential part of the installation process. The result is a fully watertight and air tight seal around any external structural opening.

FR-RS is probably one of the easiest ways to seal windows and door openings without the associated mess and cost of traditional pasted EPDM systems with the added benefit of achieving a Class B reaction to fire.
