Tips for maintaining Wital Therm MD windows in Latvian climate

Introduction

Wital Therm MD is a modern PVC window system designed for Northern European conditions. Longevity and performance depend not only on the profile and insulating glass units but also on correct maintenance. This guide offers practical tips for window owners in Latvia to keep seals tight, hardware working, and thermal performance stable.

Why maintenance matters in Latvia

• High humidity and temperature swings in coastal areas increase stress on seals and hardware.
• Snow and ice can block drainage channels, causing water to accumulate in frames.
• Proper ventilation and seasonal checks reduce the risk of condensation and mold.

Monthly quick checks

• Inspect frames and sashes for visible damage or cracks.
• Test hardware operation: turn, tilt, and close to ensure even contact.
• Wipe seals with a soft brush or damp cloth to remove dust.

Seasonal care: spring and autumn

Cleaning glass and frames

• Use a mild detergent or glass cleaner. Avoid solvents, acetone, or abrasive cleaners.
• Soft microfiber cloths or sponges are recommended. Do not use metal scrapers.

Drainage and weep holes

• Make sure drainage holes in the profile are clear of dirt and leaves. Blow them out with compressed air or carefully clear with a thin stick.
• If water accumulates, call a professional.

Seal treatment and hardware lubrication

• Seals: clean with a damp cloth and apply silicone spray 1–2 times a year if needed.
• Hardware: lubricate with light machine oil or a dedicated window grease once a year; in heavy-use situations, every 6 months.

Winter preparation

• Check sash compression: if you feel drafts, adjust the hardware or call a technician.
• Keep drainage channels clear so melting snow can escape freely.
• Avoid leaving wet rags or chemical residues on seals; these accelerate wear.

Controlling condensation

• Condensation often results from high indoor humidity. Solutions:
  • Regular airing: short, intensive ventilation for 3–5 minutes several times daily.
  • Use extractors or dehumidifiers in kitchens and bathrooms.
  • Ensure airflow around windows is not blocked.

Small DIY repairs

• Seal replacement: gently remove the old seal and insert a new one with a profile tool.
• Handle replacement: usually requires unscrewing and installing the new handle of the same model.
• For complex hardware failure call a professional to preserve settings and warranty.

When to call a professional

• Cracked IGU (insulating glass unit) or moisture between panes indicates seal failure.
• Significant profile deformation or deep damage.
• Serious issues with opening/closing that DIY cannot solve.

Tools and materials list

• Soft cloth, microfiber
• Mild detergent or glass cleaner
• Silicone spray for seals
• Light oil or window-specific lubricant
• Thin stick or soft brush for drainage
• Screwdrivers for minor repairs

FAQ — common questions

How often should I clean Wital Therm MD windows?

Generally: wash glass and frames 2–4 times a year; treat seals and lubricate hardware 1–2 times a year. In coastal or dusty areas increase frequency.

What if I see mist between the panes?

Mist between panes indicates a failed seal in the insulating glass unit. The unit typically needs replacement by a specialist or the manufacturer.

Can I use household chemicals on the frame?

Avoid aggressive solvents (acetone, white spirit), abrasive pastes, and steel brushes. These damage PVC and seals.

How to extend the life of seals?

Keep seals clean, apply silicone spray periodically, and avoid prolonged chemical exposure or mechanical stretching.

My window does not close tightly — what to do?

Try adjusting the hardware (adjustment screws) or call a service technician. Incorrect adjustments can worsen sealing and damage the frame.

What does maintenance cost?

Costs vary: basic lubrication and inspection are inexpensive; IGU replacement or complex repairs cost more. Request quotes from licensed service providers.

Conclusion

Regular care of Wital Therm MD windows in Latvian climate means periodic cleaning, clearing drainage, lubricating hardware, and controlling indoor humidity. Following these guidelines will maintain comfort and thermal efficiency for years.
