Answers to questions about window care in series 103

PVC windows installed in typical apartment blocks of the 103 series require regular maintenance to keep them airtight, thermally efficient and easy to operate. This guide provides practical cleaning instructions, seal and hardware care, and seasonal tips specific to panel-house apartments.

Why maintenance matters

• extends the life of seals and moving parts;
• reduces heat loss and drafts;
• prevents condensation and mold growth;
• keeps windows easy to use and maintains warranty conditions.

Monthly maintenance — simple routine

1. Wipe frames and glass with a soft cloth or microfiber using warm water and a mild detergent.
2. Inspect seals around the frame for cracks, flattening or damage — replace if necessary.
3. Check hardware operation: opening, locking, tilt. If it’s stiff or squeaky, apply a silicone spray or a recommended lubricant.
4. Clean drainage channels and the area under the sill.

Tip: avoid abrasive cleaners, powders and hard brushes — they damage glass coatings and PVC surfaces.

Seals: prolonging service life

• Clean seals with warm water and a mild soap; never pull or cut them with sharp tools.
• Apply a silicone-based protectant every six months to restore elasticity.
• Replace seals that are cracked, shredded or permanently compressed; if unsure, call a professional.

Hardware and lubrication

• Use silicone or graphite lubricants for metal-on-metal movement. Oil-based lubricants attract dirt.
• Apply lubricants sparingly to hinges, locking points, and sliding tracks.
• After lubrication, test all operating modes: tilt, turn, and micro-ventilation.

Seasonal tips

• Spring: clean off traces of road salt and check drainage after thaw.
• Summer: monitor seals and ventilate to prevent indoor humidity buildup.
• Autumn: ensure tight seals and adjust sashes before cold weather.
• Winter: do not force open frozen sashes — remove snow and ice first, warm the seal with lukewarm water if necessary.

Common questions (FAQ)

Why do windows fog up, and how to fix it?

Fogging typically results from high indoor humidity and poor ventilation. Solutions: regular airing (2–3 times daily), using extractors in kitchens and bathrooms, or installing a supply air valve. Persistent fog between panes indicates a failed insulated glass unit and needs glass replacement.

How to remove stubborn stains from glass?

Use a solution of warm water and a little vinegar or a dedicated window cleaner. Apply with a soft sponge and finish with a clean microfiber cloth.

Can I use household oil on hardware?

Avoid household oils; they attract dust and gum up mechanisms. Prefer silicone sprays or dry graphite lubricants designed for window fittings.

When to call a professional?

When sashes sag, don’t close tightly, or show gaps — professional adjustment or part replacement is required. Moisture between panes also requires specialist replacement of the insulated glass unit.

Simple homeowner checklist

• Monthly: clean glass and frames, inspect seals.
• Semiannually: lubricate hardware, check drainage.
• Seasonally: adjust and test airtightness.
• If in doubt: schedule a service visit for diagnostics.

Conclusion

Routine care of windows in 103 series apartments is an affordable preventive measure that saves energy and extends product life. Follow the simple steps above and address any irregularities promptly to keep windows functioning reliably for years.
