Which windows to choose for modern apartments

Choosing windows for a modern apartment is about more than appearance. The right window affects energy efficiency, sound insulation, ventilation, security and everyday convenience. This guide explains the key characteristics to consider when selecting PVC windows for apartments in Latvia.

Why the choice matters

• A window controls heat loss, noise penetration, daylight and fresh air — it shapes indoor comfort.
• The wrong choice increases heating costs, condensation risk and reduces living comfort.

Main parameters to check

• Profile chamber count (3, 5 or 7 chambers) — higher chamber count usually improves thermal performance.
• Profile width (60–90 mm and more) — wider profiles accommodate larger glass units and insulation.
• Glass unit type: single, double or triple glazing; Low-E coating and inert gases (argon, krypton) improve performance.
• Hardware class — durability, adjustability, anti-burglary features and ventilation modes.

Glass units: recommendations

• Double-glazed units with two air gaps (three panes) provide better thermal and acoustic insulation.
• Low-emissivity (Low-E) glass reduces heat loss and improves indoor comfort near windows.
• Argon-filled gaps increase insulating properties compared to air.

PVC profiles — what to look for

• 5- and 6-chamber profiles are a good compromise for apartments: performance vs cost.
• Wall thickness and manufacturer reputation affect longevity and deformation resistance.
• Finishes: white, woodgrain or matte laminates — check UV resistance and warranty.

Hardware and security

• Multi-point locking systems and robust hardware increase burglary resistance.
• Child locks and opening limiters are useful in family apartments.
• Choose hardware from known brands for easier servicing and spare parts availability.

Ventilation and condensation control

• Correct installation and hardware adjustment ensure adequate airflow.
• Micro-ventilation modes help to ventilate without fully opening the sash.
• Consider an external air inlet or mechanical ventilation if apartment ventilation is limited.

Sound insulation

• Proper combination of thicker glass, multi-chamber glass units and professional installation can provide 30–45 dB reduction.
• For busy streets, choose acoustic-rated glazing and seals.

Design and placement

• Modern interiors often favor large, narrow-profile windows to maximize light and view.
• Balcony and French windows need reinforced profiles and reliable hardware.

Budget and service life

• A quality PVC window can last 25–40 years with proper maintenance.
• Investing in energy-efficient glazing pays off over time through lower heating costs.

Quick checklist before purchase

• Verify overall Uw (thermal transmittance) of the window assembly.
• Confirm hardware class, warranty and service options.
• Measure exact openings and agree installation tolerances.
• Clarify demolition and disposal of old windows and final cleaning.
• Request samples of profile and laminate; ask for certificates.

Tip: Work with reputable suppliers that offer on-site measurement and certified installation.

Short recommendations

• City apartments: 5-chamber profile + double-glazed unit with Low-E and argon.
• Quiet residential zones: 3-chamber profiles may suffice with optimized glazing.
• Noisy streets: choose acoustic glazing and thicker glass.
