Which profiles are suitable for series 119

Series 119 refers to a common panel apartment type with specific window opening sizes and typical mounting depth. Choosing the right PVC profile for windows in a 119 apartment requires attention to mounting depth, thermal and acoustic performance, reinforcement, and glazing thickness.

Key requirements for a profile in series 119

• Mounting depth: typical openings often require profiles with 60–70 mm mounting depth. Deeper profiles are possible if you modify the sill or add extension pieces.
• Reinforcement: a steel insert of appropriate section is necessary to prevent sash sagging in larger windows.
• Number of chambers: 3–5 chambers are acceptable for basic insulation; 5+ chambers provide better energy performance.
• Glazing bead width: compatible with 24–44 mm double or triple glazing units.

Recommended profile types

• 58–60 mm (3–4 chambers) — suitable for replacing old wooden frames with minimal changes to the opening; budget-friendly.
• 70 mm (4–5 chambers) — the optimal choice for series 119: good thermal performance and compatibility with 2‑chamber insulating glass units.
• 76–88 mm (5+ chambers) — for deep renovation and high energy efficiency requirements.

Common manufacturers and lines

• Rehau, Veka, KBE — established European systems offering multiple mounting depths and accessory options.
• Local brands — can be more affordable, but check reinforcement quality and seals.

Installation specifics in series 119

• Accurate measurement is essential. A professional will check the opening, sill depth, and evenness of reveals.
• Removal of the old frame often requires preparing the mounting surface, including vapor and waterproofing layers.
• Ensure proper ventilation gaps and sealing; do not block vents when installing sills or trims.

Thermal and acoustic performance

• For busy streets, choose a 70 mm profile with a 2‑chamber IGU of 36–44 mm and quality seals for effective sound reduction.
• For interior or quieter locations, a 58 mm profile with a 1‑chamber IGU may suffice but will be less energy efficient.

Practical advice

• For energy savings: opt for 70 mm, 5‑chamber profiles and a two‑chamber glazing unit.
• If you replace only the frame: pick a profile with a mounting depth matching the existing opening (58–60 mm typical).
• Prefer EPDM seals, robust steel reinforcement, and a reliable warranty from the supplier.

FAQ

Can I fit a 70 mm profile instead of the old wooden frame?

Yes, but you must verify sill depth and possibly replace the sill or use extension profiles to achieve proper fit.

Is steel reinforcement necessary for large windows?

Yes — reinforcement prevents deformation and ensures long‑term stability of wide sashes.

Which profile best reduces street noise?

A 70 mm profile combined with a 2‑chamber IGU (36–44 mm) and good seals will significantly reduce noise.

What matters more: number of chambers or quality of seals?

Both are important: chambers improve thermal performance, while seals ensure airtightness and longevity.

How much does replacing a profile in a 119 series cost?

Costs vary by profile, glazing, and installation complexity. Request a tailored estimate based on measurements.

Conclusion

Choosing a profile for a 119 series apartment depends on the opening depth, insulation needs and budget. A 70 mm, 4–5 chamber profile with proper reinforcement and quality seals is a reliable all‑round solution for most situations in this building type.
