Filoform MD5 Duct Sealing System Vs DIY Expanding Foam
Posted on 05 February 2024
Most UK utilities have banned the use of expanding foam as a measure to effectively seal cable ducts against water ingress, gas migration or fire spread. Failure to correctly and safely seal cable ducts can inflict catastrophic damage to LV MV HV Electrical Distribution Networks, Substations and Power Supply.
Thorne & Derrick International are the UK distributors for Filoform, a leading manufacturer of cable joints, duct seals and special resins for installation in the utilities, telecom, traffic, rail, fibre optic, street lighting and construction industries.
Polyurethane foam (PU) has witnessed a increase in popularity as a construction material due to its versatility. PU can be applied to walls, roofs, ceilings, floors providing insulation and structural support. Technological advancements have overcome engineering challenges, allowing for low-density foam products that are easy to install on-site.
Duct Seals – Sealing Cable Ducts

Whilst expanding foam serves well for sealing small gaps, filling voids, cracks and insulating it falls short beyond these applications. Often comprised of subpar polyurethane, many expanding foams lack the necessary properties for effective sealing or adhesion.
The use of expanding foam in construction and maintenance projects across various industries have grown over time; however it faces major problems when applied wrong, or designed into a project where the foam specifications doesn’t match the requirements of the projects.
Comparing MD5 Duct Sealing Resin to Generic expanding foam
Assessing the particular duct seal scenario and determining the project’s goals are important when selecting an efficient seal. Taking into account elements such as :
- Cable Presence
- Water blocking specifications
- Fire Stop standards
- Building entrance points
- Gas and chemical problems
During the design phase choosing a sealing system that fits the needs of the entire project should be made easier by taking the circumstances into consideration.
Sealing Ducts require precision, a professional would strongly advise against using DIY expanding foam for this purpose due to potential complications. For guidance in your inquiries please contact us today!
