Powerbase VOC Top Hat - Pre-formed Penetration Seal - 100mm (GTNV 100BG)

Powerbase VOC Top Hat – Pre-formed Penetration Seal - 100mm (GTNV 100BG)

100mm Powerbase VOC Top Hat (GTNV 100BG) is a pre-fabricated penetration seal designed for use with Powerbase VOC gas barrier membranes, providing a secure and effective method of sealing around service pipe penetrations. Engineered to maintain the continuity of the barrier system, it helps prevent the ingress of hydrocarbons, volatile organic compounds (VOCs), methane, radon and carbon dioxide through membrane penetrations.

Manufactured to simplify on-site detailing, the Powerbase VOC Top Hat forms an integral part of a comprehensive ground gas and contaminant protection system. Its pre-formed design enables fast installation while helping to achieve reliable gas-tight and vapour-tight seals around service entries. It is suitable for use in residential, commercial and industrial developments constructed on contaminated land or in areas requiring enhanced gas protection. Powerbase VOC Top Hat provides a dependable and easy-to-install solution for sealing service penetrations, helping to preserve the integrity and performance of VOC, hydrocarbon and ground gas barrier membrane systems.
