5mm x 45mm x 45mm Hush 45L Flanking Strip – Perimeter Seal - 2m length

5mm x 45mm x 45mm Hush 45L Flanking Strip is a highly resilient acoustic isolation material engineered to prevent flanking sound transmission around the perimeters of acoustic flooring systems. It effectively decouples the floating floor from direct contact with rigid surrounding structures, ensuring compliance with Building Regulations Part E (Resistance to the Passage of Sound) and enhancing overall acoustic performance. This flanking strip is installed vertically around the entire perimeter of a floating floor – whether it's an acoustic overlay board system, a screed, or a battened floor – where it abuts walls, columns, or other fixed building elements. Its key function is to absorb impact energy and airborne sound vibrations that would otherwise travel down the floor into the wall and then flank into adjacent rooms. By creating a continuous resilient break, the Hush-45L prevents sound from bypassing the main floor treatment. Its closed-cell structure makes it resistant to moisture and ensures long-term performance without degradation.

CHARACTERISTICS

• Comprises of pre-formed angled isolation strip.
• Made from durable, high-density polyethylene foam, resilient closed-cell material.
• Mitigates the transfer of impact sound and vibration through perimeters.
  
• Creates a crucial isolation break between acoustic constructions and rigid structures.
  
• Effectively addresses flanking transmission paths.
  
• Absorbs impact energy and dampens vibrations.
  
• Prevents sound energy from bypassing main acoustic insulation.
• Resistant to moisture.
  
• Maintains long-term performance without degradation due to its closed-cell structure.
  
• Resilient and flexible, allowing it to conform to minor irregularities for a continuous seal.
• Easy to cut and install.
  

APPLICATION

• Floating floor systems (e.g., around acoustic overlay boards, screeds).
• Independent floor joists where they meet perimeter walls or structural elements.
