armack Professional Low-Expansion Gun Foam (750ml) – Multi-Season

A technologically advanced, single-component polyurethane foam designed for professional installation and sealing applications. Its fine-cell, closed-pore structure provides excellent thermal insulation properties and exceptional dimensional stability. 

The low-expansion formula effectively eliminates the risk of door and window frame deformation, while the multi-season composition allows for precise application across a wide range of temperatures.

Key Advantages:

• Excellent Adhesion: Bonds strongly to most building materials, including brick, concrete, steel, wood, and hard PVC.
  
• Dimensional Stability: Zero primary or secondary shrinkage guarantees long-lasting durability and tight seals for years.
  
• Premium Insulation: The dense structure provides an exceptional thermal and acoustic barrier.
  
• Fast Processing: Short skin formation time (up to 10 minutes) and optimal curing time significantly accelerate assembly work.
  

Applications:

• Professional installation of window and door frames (wood, PVC, steel, aluminum).
  
• Thermal insulation of roofs, flat roofs, and insulation systems.
  
• Filling of wall penetrations, gaps, and cracks.
  
• Soundproofing and acoustic insulation of partition walls.
  
• Sealing of water supply and central heating networks.
