PORTALS PLUS

PORTALS PLUS is a brand specializing in roof vent pipe flashings and sealing products for commercial and residential roofing applications. The product line includes round-base boots, rectangular-base boots, and roof tape kits designed to provide weatherproof seals around vent pipes penetrating various roof types. Round-base boots are available in diameters such as 11 inches and 14 inches, with options for EPDM or aluminum construction, accommodating pipe sizes up to 6 inches. These boots feature either open or closed top openings, with EPDM collars for flexibility and durability. Rectangular-base boots are offered for corrugated metal roofs and shingled roofs, with square or rectangular bases, and are constructed from aluminum or steel with EPDM or elastomeric collars. They are designed for single-pipe installations, with pipe sizes ranging from 2 to 4 inches. Roof tape kits include double-sided adhesive seam tape for repairing single-ply EPDM roofs, supplied in a can with a roller for application. PORTALS PLUS products are built to meet standard roofing industry requirements, with materials selected for resistance to UV exposure, temperature extremes, and weather aging. The brand focuses on functional reliability rather than decorative features, making its products suitable for maintenance, repair, and new construction projects where pipe flashings must maintain integrity over time. 3G Electric stocks multiple SKUs of PORTALS PLUS boots and tape kits, providing procurement options for plant engineers, maintenance managers, and contractors who need consistent supply for ongoing roofing work. The inventory covers common pipe sizes and roof types, allowing buyers to select the appropriate flashing based on roof slope, base shape, and pipe diameter. Logistics support is available for global shipments, ensuring that these components reach job sites without delay. For technical buyers, the key specifications to consider include the base shape (round or rectangular), roof type compatibility (flat, corrugated metal, shingled), pipe size capacity, collar material (EPDM or elastomeric), and top opening type (open or closed). These factors determine the flashing’s fit and sealing performance under specific roof conditions. PORTALS PLUS products are not marketed as premium or specialized; they are standard-grade components that meet common industry expectations for weatherproofing roof penetrations. 3G Electric’s catalog provides detailed part numbers and specifications to facilitate accurate ordering.

Frequently asked questions

Common questions about PORTALS PLUS from 3G Electric.

What materials are used in PORTALS PLUS round-base boots?

PORTALS PLUS round-base boots are available with collars made from EPDM rubber, which provides flexibility and weather resistance. The base can be constructed from EPDM or aluminum, depending on the model. For example, the 11-inch diameter boot (MPN 11015) has an EPDM collar and an EPDM base, while the 14-inch diameter boots (MPN 4YN30 and 4YN31) feature aluminum bases with EPDM collars. The choice of material affects the boot's durability and compatibility with different roof surfaces.

How do I select the correct PORTALS PLUS rectangular-base boot for my roof type?

PORTALS PLUS rectangular-base boots are designed for specific roof types. For corrugated metal roofs, use the model with a square base and EPDM collar (MPN 4YN36). For shingled roofs, choose boots with a rectangular base and steel construction, such as MPN 4YN39 (for 2-inch pipes), 4YN40 (for 3-inch pipes), or 4YN41 (for 4-inch pipes). These boots have elastomeric collars that conform to the pipe. Always verify the pipe size and roof material before ordering.

Can PORTALS PLUS roof tape kits be used on all EPDM roofs?

PORTALS PLUS roof tape kits (MPN 4YN42) are specifically formulated for single-ply EPDM roofs. The kit includes a 3-inch by 20-foot roll of double-sided adhesive seam tape and a roller for application. It is not recommended for use on other roof membranes such as TPO, PVC, or modified bitumen, as the adhesive may not bond properly. For best results, ensure the roof surface is clean and dry before application.

What is the difference between open and closed top openings on PORTALS PLUS boots?

PORTALS PLUS boots with open top openings have a pre-cut opening that allows the boot to slide over the pipe during installation. Closed top openings require the installer to cut the opening to match the pipe diameter. For example, the 11-inch round-base boot (MPN 11015) has an open top, while the 14-inch aluminum boots (MPN 4YN30 and 4YN31) have closed tops. Closed tops offer more flexibility for custom pipe sizes but require additional cutting.

Are PORTALS PLUS boots suitable for flat roofs?

Yes, PORTALS PLUS round-base boots are designed for flat roofs. Models like the 11-inch EPDM boot (MPN 11015) and the 14-inch aluminum boots (MPN 4YN30 and 4YN31) are specified for flat roof applications. The round base provides a stable seal on low-slope surfaces. For sloped roofs, rectangular-base boots are more appropriate, as they conform to the roof pitch.
