QL-9640 weather seal for PVC windows and doors

QL-9640 weather seal for PVC windows and doors

• excellent memory – returns to original shape after compression
• stability – low / no stretch gained by rigid insert or glass fibre internal cord
• outstanding compression – low compression forces, unaffected by temperature variance, low friction
• acoustics – excellent sound insulation
• thermal conductivity – unrivalled thermal performance, up to 10 times more efficient than other sealants
• paint and stain proof – properties unaffected by standard paints and stains
• protection – unaffected by rot, fungi, UV-light or ozone, dirt-repellent
• temperature – wide operating range under extremely cold and warm weather
• compatible with cleaning agents 
• efficient installation – quick installation without corner cutting

• polyurethane (PU) foam core - high durability, superior recovery performance
• polyethylene (PE) film - weather and UV-resistant
• glass fibre thread or polypropylene (PP) insert - prevents elongation and shrinkage
