V-Seal

Pipework through roofs and walls, sealed simply and effectively

Designed to create a durable, flexible, weather and airproof seal around penetrations through the building envelope.

The range includes pipe flashings for sealing around pipes, vents, ducts, chimneys, electrical cables, solar pipework and other services that pass through the roof or external walls.

Pipe flashings are available in a wide range of pipe sizes and each flashing has pipe diameters marked on the ribbed measurement lines – providing easy identification of the size ranges on site, and acting as a guide to ensure an even cut is made around the cone.

Pipe flashings for metal roofs

V-Seal pipe flashings for metal roofs include products suitable for pipe diameters between 10mm and 750mm to suit standard and retrofit applications, as well as for cable dimensions between 3mm and 50mm.

Square base for easy installation

A square base ensures a watertight seal on profile material, where it can be difficult to cut a perfectly round clearance hole. A malleable grade aluminium support ring provides reinforcement and can be contoured to the roof sheet profile.

Flexible sleeve

The flexible sleeve maintains its shape and prevents collection of water or dust, making it suitable for use on both flat or pitched roofs. The sleeve also allows for expansion, contraction, and building movement - whilst maintaining a weatherproof seal.

High quality materials

Pipe flashings are available in EPDM for cold pipes and silicone for high temperature pipes. These high quality materials are resistant to ozone and ultraviolet light – with a 20 year product replacement warranty available as standard against faulty manufacture or materials.

Ease of installation

V-Seal pipe flashings for metal roofs are designed to be pulled down from the top of the pipe. In situations where this is not possible due to obstruction, it can be cut down the seam, wrapped around the penetration and crimped together using VSRFC retrofit clips.

V-Seal fixing kits

Available for installing V-seal pipe flashings, including all the components required to carry out the installation on metal, plastic or fibre cement roofing panels.

Extensive range

Wide range of sizes to suit cables of 3mm diameter, up to pipework of 750mm.

Pipe flashings for slate and tile

Including products suitable for pipe diameters between 10mm and 450mm – with the option of aluminium or lead bases.

Malleable base

Pipe flashings for slate and tiled roofs feature a large rectangular lead or aluminium base, which thanks to its malleability, can be formed to match the profile of the roof. The large base ensures there is ample material for dressing over the tiles around the penetration. All the lead-based products are manufactured from Acrylead – a safe, baked acrylic primer coating for lead sheet. Acrylead is safe to handle and inhibits water from coming into contact with lead and its oxides, preventing lead run-off from staining the roof and entering ground water systems.

Flexible rubber cone

Flexible material and design means that each rubber cone is suitable for a wide range of pipe sizes and roof pitches without the need for fabrication. As with the pipe flashings for metal roofs, these pipe flashings also accommodate expansion, contraction, and building movement – all whilst maintaining a weatherproof seal.

High quality materials

In EPDM or silicone for different applications and different temperature types – high quality and resistant to ozone and ultra violet light – with a 20 year product replacement warranty against fault manufacture.
