Professional Polycarbonate Channel Sealing Solution
Geotextile diffusion tape is a specialized breathable adhesive designed for sealing the open ends of multiwall polycarbonate sheets. This 38mm tape acts as a protective barrier against dust, insects, and organic contaminants. It facilitates the drainage of internal condensation to prevent mould and algae growth. The product ensures long-term clarity and structural integrity for greenhouse and roofing installations.
Preventing Contamination in Polycarbonate Channels
Open polycarbonate channels often collect dust, insects, and moisture, which leads to unsightly algae growth and reduced light transmission. This contamination compromises the insulation performance and aesthetic quality of your greenhouse panels over time.
Our geotextile diffusion tape provides a reliable seal that blocks particles while remaining breathable. By allowing moisture to escape, it maintains a clean, clear, and dry environment inside the panel flutes for extended durability.
