Regular maintenance of fittings is the key to a long service life of windows. Without proper maintenance, mechanisms wear out quickly, creaking appears, and the tightness is broken.

Main elements for maintenance

• Moving mechanisms: hinges, handles, locking elements

• Seals

• Drainage systems

• Strike plates

Maintenance schedule

Optimal frequency:

• Lubrication of moving elements - 2 times a year (spring/autumn)

• Cleaning of seals - every 6 months

• Checking of drainage holes - once a year

Recommended materials:

• Specialized lubricants

• Silicone grease for seals

• Soft cleaning agents

• Lint-free wipes

Step-by-step maintenance instructions
