IGLO 5: profile overview and key features

IGLO 5: profile overview and main features

The IGLO 5 profile is a widely used PVC window system that offers a practical balance of thermal performance, rigidity and affordability. Below is a clear overview of construction details, benefits, limitations and practical tips for choosing and maintaining IGLO 5 windows.

Technical highlights

  • Design: 5-chamber PVC profile for window frames.
  • Installation depth: typically around 70 mm.
  • Glazing: compatible with double- and triple-glazed units.
  • Reinforcement: steel reinforcement inside the frame for strength and stability.

Thermal and acoustic performance

Thanks to the multi-chamber design and proper glazing selection, IGLO 5 provides good thermal insulation for standard residential needs. Key points:

  • Reduces heat loss compared to older single-frame windows.
  • When paired with an energy-efficient glazing unit, it supports comfortable indoor temperatures in temperate climates.
  • Offers better sound insulation than simple profiles but for high-noise streets, deeper profiles and special acoustic glazing are recommended.

Seals and airtightness

Most IGLO 5 configurations come with two or three sealing contours that improve airtightness, reduce drafts and prevent moisture ingress. Quality gaskets are essential for long-lasting performance.

Hardware and security

IGLO 5 is compatible with a wide range of modern hardware: handles, anti-burglary elements, micro-ventilation functions and restrictors. Additional security upgrades (reinforcement plates, special locks) are available for higher protection.

Advantages

  • Good price-to-performance ratio for apartments and private houses.
  • Easy maintenance: seals replacement and hardware servicing are straightforward.
  • Versatile: supports various glazing types (low-emissivity, acoustic, multifunctional).
  • Available in multiple colors and finishes.

Limitations and considerations

  • For very cold climates or passive-house level insulation, profiles with greater installation depth and more chambers may be preferable.
  • Correct installation is crucial: poor mounting negates the profile’s benefits.
  • Check reinforcement thickness and PVC quality — they affect long-term stability and durability.

How to choose IGLO 5 for your project

  1. Assess your climate and insulation needs: IGLO 5 suits most urban and suburban apartments.
  2. Select the right glazing unit: an argon-filled double- or triple-glazed unit with low-E coating improves performance.
  3. Specify hardware: choose proven hardware brands with anti-corrosion protection.
  4. Verify seals and reinforcement during installation acceptance.

Tip: Ask your supplier for technical datasheets and test reports on thermal resistance and sound insulation.


Maintenance

  • Clean seals and lubricate hardware 1–2 times a year.
  • If drafts appear, check sash alignment and condition of gaskets.
  • Avoid aggressive chemicals that may damage PVC and seals.

FAQ (short)

  • Lifespan? With proper installation and maintenance — 20+ years.
  • Suitable for balconies? Yes, but consider exposure and climate when choosing glass and finish.
  • Difference from 3-chamber profiles? Better thermal performance and rigidity.

Conclusion

IGLO 5 is a practical, economical choice when you need reliable PVC windows without premium cost. With the correct glazing and professional installation, it provides comfortable indoor conditions and reasonable sound insulation. For highest energy-efficiency demands consider advanced systems with larger depth and enhanced chamber design.
