Windows
Adhesives support window performance and production efficiency: weather resistance, thermal insulation design goals, and reliable bonding across wood, PVC and aluminium systems.
- Durable bond lines for long-term weather exposure
- Process stability for cost-effective production
- Solutions for wood windows and profile lamination systems
Application overview
Manufacturing and laminating of window elements
Windows protect against weather while providing light and ventilation. Modern designs must also meet requirements such as thermal insulation and increased security, while manufacturers need efficient, repeatable processes.
For wood windows, dispersion systems such as PVAc or EPI are used to support resistance to water and heat, contributing to durability and service life. For profile lamination on PVC and aluminium, PUR hot melts and compatible primers help ensure reliable adhesion across diverse surface energies and production speeds.
Selecting an adhesive system that matches substrates, geometry and process parameters improves quality, reduces rework, and supports stable long-term performance.
