Maintenance and warranty

Maintenance

  • The condition of the window’s surface treatment should be inspected once a year.
  • The treated windows have been treated with clear and water-soluble TEKNOGRUND 353 wood protection with decay, blue stain and mould-prevention agents. TEKNOGRUND 353 only provides short-term protection (approx. one year in outdoor conditions).
  • The white windows are painted with water-soluble paints by Teknos. The standard colour is white NCS-30502Y. Repair any cracks or chips in the painted surface.
  • Lacquered windows/windows with translucent coating are treated with one coating of translucent wood protection, after which a coating of clear lacquer is applied. Two coats of clear lacquer are applied to lacquered windows.
  • Windows with Biobe valves should be cleaned once a year, read more at www.biobe.fi
  • Insect screens should be cleaned once a year or when necessary. Read more at www.solar.fi
  • Locks and espagnolettes should be lubricated once a year. Lubricate the window stoppers when necessary.
  • The condition of the gaskets should be inspected once a year.
  • Only use neutral window cleaning products to clean windows. Solvents should not be used to clean the glass surface unless absolutely necessary.
  • The wooden surfaces should be cleaned using only a small amount of water and avoiding unnecessary abrasion.
  • Wider frames (over 130 cm) should be supported when opened to avoid the frame being damaged.
  • Always use a special window key to open the window. When closing the window, make sure that all locks are closed.
