Profilez window profiles are made of weathering resistant high-quality uPVC that requires low maintenance.
Common soiling on the even, non-porous and hygienic surface caused by rain and dust can easily be removed with
normal washing-up liquid.
Never use cleansing agents that can damage the surface as abrasives or chemicals (e.g. nitro diluter), benzene or similar agents. Clean your windows as required according to the type and level of soiling.
The gaskets of your uPVC window are made of high-quality weathering and ageing resistant rubber.
Remember when cleaning your windows to also remove dust and soiling from the gasket.
To durably conserve the gaskets’ elasticity and functionality apply special silicone oil every now and then.
To conserve your hardware’s functionality and movability you should lubricate it once in a while.
Use oil to lubricate the movable parts of your hardware and non-corroding grease or petroleum jelly (Vaseline)
for the locking points. By this means you can conserve your windows’ functionality.
Modern uPVC windows present such a high tightness that no natural air exchange can take place.
Proper ventilation in combination with modern windows saves heating costs and creates a healthy and hygienic room climate.
Cross ventilation with two opposite windows is especially quick and effective – one single open window is sometimes not enough.
Ventilate at least five to ten minutes to let in fresh air.
It is recommended to ventilate three to four times a day.
Remove items that obstruct the air flow, e.g. move furniture away from the wall a little.
Ventilate more frequently in the case of additional humidity, for example when cooking, bathing, taking a shower etc.
Please remember: A misted-up window is the best indicator that ventilation is required.
Despite all the care taken by the craftsmen during installation, soiling as mortar splatters,
fingerprints, wallpaper paste, colour splatters etc. may occur.
Most soiling can easily be removed. Mortar and colour splatters generally can be removed with a semi-rigid putty knife.
Carefully scrape the soiling off and wipe with a damp cloth.
Take care not to damage the surfaces as the small, sharp pebbles may leave scratches.
Adhesive residues on the glass can carefully be removed with a sharp razor blade.
