Tips for choosing glazing units in series 119

Tips for choosing glazing units in series 119

Apartments in series 119 panel buildings have typical features: standard-sized openings, relatively thin exterior walls and close neighbours. Choosing the right glazing unit (insulated glass unit, IGU) reduces heat loss, lowers noise and prevents condensation. Below are practical tips for owners of PVC windows in series 119.

1. Consider the building specifics

• Series 119 buildings usually have lower wall insulation, so enhancing window thermal performance is important.
• Note window orientation: north-facing windows need maximum insulation; south-facing need solar control.

2. Double vs. triple glazing

• A double-glazed IGU (two chambers) is a balanced solution for cost and performance.
• A triple-glazed IGU provides superior thermal and acoustic insulation and is recommended for corner or north-facing apartments.

3. Glass types and energy efficiency

• Low‑E glass (low emissivity) reflects infrared heat back into the room and reduces heat loss.
• Position Low‑E coatings on inner glass surfaces to improve winter performance.
• Filling the cavity with argon gas improves thermal and acoustic properties compared to air.

4. Sound insulation

• For windows facing busy streets choose laminated glass or thicker outer panes.
• Using different pane thicknesses (e.g., 4 mm + 6 mm) helps block a wider range of frequencies.

5. Spacer systems

• Warm Edge spacers reduce thermal bridging at the perimeter and lower condensation risk.
• Avoid cold aluminum spacers in harsh climates.

6. Airtightness and ventilation

• Highly airtight windows reduce drafts but require adequate ventilation to prevent humidity build-up.
• Consider trickle vents or micro-ventilation features in the sash.

7. Safety glass

• For lower floors and balcony doors, tempered or laminated safety glass is advisable.
• Laminated glass stays held together when broken, reducing infiltration risk.

8. Condensation and maintenance

• Condensation indicates temperature differences and ventilation issues. Warm Edge spacers and argon reduce this tendency.
• Regularly clean drainage channels and inspect seals.

9. Measurement and installation

• Accurate measurements avoid gaps and cold bridges. Allow for proper installation gap and sealing.
• Use certified installers to ensure correct sealing and longevity.

10. Cost‑benefit recommendations

• For many series 119 apartments a double-glazed unit with Low‑E, argon and a warm edge spacer gives the best value.
• Triple glazing is justified for northern exposures or very noisy locations if the budget allows.

Frequently Asked Questions (FAQ)

Q: Is argon better than air in IGUs?

• Yes. Argon is denser and has lower thermal conductivity, improving heat retention and sound insulation.

Q: Will replacing the glazing unit reduce window fogging?

• Often yes, especially if the new unit includes a warm edge spacer and improved insulation; but ventilation must also be addressed.

Q: Do south-facing windows need triple glazing?

• South-facing windows benefit more from solar control features than from triple glazing. Consider solar Low‑E coatings or reflective glass.

Q: Which glazing lasts longer?

• Longevity depends on frame quality, spacer system and installation. Proper installation and warm edge spacers extend service life.

Q: How much does it cost to replace an IGU in a series 119 apartment?

• Costs vary by size, glass type and options (argon, warm edge, lamination). Contact our specialists for an on-site measurement and quote.
