Schlegel QL 3072 Gasket for Wooden Windows Doors Furniture

Schlegel QL 3072 Gasket – Perfect Seal for Wooden Doors and Windows

The Schlegel QL 3072 gasket is designed to provide an effective and long-lasting seal on wooden doors and windows.

Thanks to its polyurethane foam structure covered in polyethylene , it protects from atmospheric agents and helps maintain internal comfort, reducing heat loss and insulating from external noise. Resistant to UV rays and humidity , it retains its elasticity over time without deteriorating.

The Schlegel QL 3072 seal stands out for its compact dimensions and versatility, making it ideal not only for wooden windows, but also for internal doors and furniture.

Compared to other models such as the QL 3096, it has a smaller rebate (10 mm) and a lower compression force, making it perfect for applications with narrower grooves and lower thermal and acoustic insulation requirements.

Q-LON Polyurethane Foam Seals: Proven Quality and Reliability

Schlegel Q-LON gaskets combine innovative materials and advanced technologies to deliver superior sealing, insulation and weather resistance performance.

Thanks to rigorous quality controls and independent testing, Q-LON gaskets are among the most reliable in the industry, ensuring durability and consistent performance even in extreme conditions.

Key Benefits of Schlegel QL Seals

• Excellent elastic memory, with the ability to recover its original shape after compression;
• Stable structure, with rigid or fiberglass insert to minimize elongation;
• Ease of compression, thanks to reduced closing forces that are independent of temperature variations;
• Advanced sound insulation, effectively reducing external noise;
• Excellent thermal conductivity, improving the energy efficiency of the windows;
• Resistance to paints and dyes, without altering the properties of the gasket;
• High stability, with resistance to decay, mold, UV rays and ozone;
• Wide range of colors, including white, black, brown and gray, with the possibility of customization;
• Perfect operation in any climate, with excellent performance in both hot and cold environments.

Construction and materials of Schlegel Q-LON gaskets
Q-LON gaskets are made with a polyurethane (PU) foam core, which ensures durability and excellent recovery capabilities. The polyethylene (PE) coating makes them resistant to the elements and UV rays, while a fiberglass or polypropylene (PP) thread prevents deformation over time. The exterior can be smooth or embossed, for greater resistance to contamination and compatibility with cleaning agents.

Tested reliability of Schlegel Q-LON gaskets
Independent tests show that Q-LON gaskets maintain their properties significantly longer than other sealing materials. After more than 10,000 opening and closing cycles, they retain their performance, while alternative materials show signs of deterioration.

Compliant with the EN 12365:2003 standard , Q-LON gaskets are the ideal choice for those looking for air and water tightness, thermal insulation and noise reduction, with a certified and long-lasting product.
