⚡ At a Glance
- • Sealing Performance: Expandable polyethylene resists water and fills irregular gaps effectively
- • Best for: Tradespeople and DIYers sealing floor gaps, windows, door frames and joints
- • Not ideal for: Very narrow joints below recommended width or decorative exposed seams requiring trim
Expandable polyethylene foam, 15mm outer diameter supplied as a 50m roll. Flexible, lightweight material trims with scissors and forms a firm backing for sealants.
Neat, concealed joins - with expandable polyethylene core
Expandable polyethylene compresses into irregular gaps, conforming to uneven surfaces and creating a uniform backing depth for sealant. Supplied as a continuous roll that can be cut to length with scissors or standard cutting tools.
Creates tidy, consistent joints that hide gaps and produce a finished look, especially useful around newly fitted floors and skirting.
Improved moisture resistance - thanks to closed-cell material
Closed-cell expandable polyethylene resists water ingress and reduces capillary movement behind sealant layers. The material’s structure prevents easy absorption, helping sealants adhere without becoming saturated.
Helps prevent water and dust infiltration at joints, making it suitable for plumbing trims and damp-prone junctions where a firmer seal is required.
Faster, custom installs - with a trim-to-fit roll format
A 50m roll with a 15mm outer diameter allows continuous runs and on-the-spot sizing; recommended practice is to pick a rod slightly larger than the joint width for optimal compression. Lightweight flexibility eases insertion into tight gaps.
Speeds up sealing on long runs and allows tailored fits for varied joint widths, reducing time spent restocking and measuring on site.
