Eurovent PUR Nail Sealing Tape for Roof Underlays 40 mm × 25 m

Eurovent PUR nail sealing tape is a single-sided self-adhesive foam sealing tape designed for sealing nail and staple penetrations in roof underlays and limiting moisture ingress into roof structures. The flexible polyethylene (PE) foam tape is installed between the roof membrane and counter-batten to seal fastening points.

Eurovent PUR sealing tape is manufactured from closed-cell polyethylene foam with a solvent-free acrylic dispersion adhesive applied to one side. The tape is supplied without a removable release liner.

Its elastic foam structure helps compensate for minor surface irregularities between the counter-batten and roof membrane. Sealing nail and staple penetrations helps reduce the risk of water and moisture reaching rafters and thermal insulation.

The tape is waterproof and UV-resistant, with temperature resistance from −30 °C to +90 °C. The minimum application temperature is +5 °C. The foam can also be used as an acoustic insulation and separation material.

Each roll measures 40 mm × 25 m.

Applications & Usage

Eurovent PUR nail sealing tape is primarily used between roof underlay membranes and counter-battens to seal fastening points created by roofing nails and staples.

The tape is applied to the roof membrane along the intended counter-batten position. The counter-batten is then installed over the tape. The flexible foam helps fill minor irregularities and seal fastener penetrations.

Typical applications include:

• Sealing nail holes in roof underlays

• Sealing staple penetrations in roof membranes

• Sealing beneath counter-battens

• Protecting rafters and thermal insulation against moisture ingress

• Sealing roof construction joints

• General construction sealing and insulation

• Acoustic insulation and separation applications

The minimum application temperature is +5 °C. Apply the tape to a suitable substrate and press firmly to establish proper adhesive contact.
