PVC joinery maintenance rules
PVC windows are extremely easy to care for and require minimal maintenance. But you should still clean and care for PVC windows regularly – especially the glazing.
To ensure long and lasting enjoyment of your PVC joinery we recommend this regular cleaning procedure:
1. Remove lime and mortar splashes!
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.
2. Ventilate rooms several times a day!
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.
3. Do not use caustic fluids
For normal cleaning of the frame surface use a solution of mild dishwashing liquid. Do not use scouring agent, paint thinner or . For stubborn dirt always use special cleaning agents that can be obtained from the window supplier or from a window specialist.
4. Regular cleaning on the outside!
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.
5. Lubricate fittings!
Lubricate the fittings at least once a year to ensure ease of movement at all times.
6. Tighten handles!
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.
7. Care for the seals!
Rub the seals in the frame twice a year with sealing agent e.g. talcum, deer tallow or silicon oil (from specialists), to keep them soft and in good working order. Damaged seals have to be replaced.
8. Clean drainage openings!
Check the drainage openings in the frame profiles every now and again. Cleanliness is important for satisfactory drainage.
