Avoid lime and mortar splashes on the profile, glazing and fittings. Both the profile and the glazing could be damaged and fittings
jammed as a result of solidified mortar residue.
An inflow of colder air lowers the relative humidity in the room and creates a healthier room climate. Preferably ventilate the living
area several times a day, as a relative humidity of over 60 % can lead to mould growth.
For normal cleaning of the frame surface use a solution of mild dishwashing liquid. Do not use scouring agent or paint thinner.
For stubborn dirt always use special cleaning agents that can be obtained from the window supplier or from a window specialist.
Clean the outside of your windows regularly. Pollen, tar or ferrous particles may be burned in by the sun’s rays. Once a layer has
deposited it is not easy to remove.
Lubricate the fittings at least once a year to ensure ease of movement at all times.
Always tighten loose window handles. You can find the screws by lifting the cap under the handle and turning it out of the vertical
into a horizontal position.
