Question:
How does the skirt fit to the existing GRP roof. Many thanks
Answer:
The Ubbink OFT5 is supplied with an EPDM rubber flashing specifically designed to bond directly to a range of flat‑roof finishes, including GRP roofing systems. The EPDM skirt is installed by adhering it to the GRP surface using a suitable GRP‑compatible adhesive or sealant, creating a secure and watertight seal. The product includes a rubber flashing that forms this seal around the vent base.
