The adhesive perimeter strips made of lightweight closed-cell expanded polyethylene are an essential component for the construction of professional screeds and flooring systems. Waterproof, mould-resistant and resistant to chemical attack and the alkaline reactions of concrete, they ensure consistent long-term performance. The Isoplam compressible adhesive perimeter strip is easy to install and provides high resistance to thermal shock thanks to the special adhesives used. Essential for industrial floors, stamped surfaces, traditional and lightweight cement screeds, and underfloor heating systems, the perimeter spacer strip ensures the correct behaviour of the screed during settling and expansion phases.

The perimeter strip, also known as a screed edge strip, simultaneously provides thermal insulation, an expansion joint and sound insulation, preventing direct contact between the flooring and vertical surfaces. The strip isolates the concrete from water absorption by the masonry, helps reduce horizontal stresses on adjacent structures and improves the durability of the entire flooring system. Isoplam perimeter strips are available in different heights and in 5 or 8 mm thicknesses, adapting to all design and application requirements.
