Where to Order Windows with Advanced Insulation in Bucharest? Complete Guide 2026

What Does "Advanced Insulation" Really Mean for Windows?

The term "advanced insulation" is used by many suppliers in Bucharest without a clear definition. Technically, a window system with advanced insulation must simultaneously meet several criteria:

Thermal transmittance Uw ≤ 1.0 W/(m²K) — the minimum threshold for nZEB standard in Romania. Standard double glazing has Uw = 1.3–1.6 W/(m²K), so it doesn't qualify.

Triple glazing pack with two chambers filled with argon or krypton gas and at least one Low-E glass layer. The pack's Ug must be ≤ 0.6 W/(m²K).

PVC profile with minimum 6 chambers (depth 82–92 mm) or aluminium profile with thermal break of minimum 34 mm, Class A (outer walls ≥ 3 mm).

Warm Edge spacer inside the glazing pack — eliminates the thermal bridge at the edge and prevents condensation on the inner sill.

RAL/nZEB-compliant installation — pre-compressed bands at exterior, vapour barrier at interior, metal anchors.

Without all these elements together, a manufacturer cannot legitimately speak of "advanced insulation".

Types of Advanced Insulation Windows Available in Bucharest

1. Salamander bluEvolution 92 PVC — The nZEB Reference Standard

6-chamber profile, 92 mm depth, 3 EPDM gaskets, Uf = 0.9 W/(m²K). Fitted with 52 mm triple glazing, argon, Low-E SGG and Warm Edge spacer, achieves Uw = 0.66–0.8 W/(m²K) — passive house performance.

2. Salamander bluEvolution 82 PVC — The Quality-Price Balance

6 chambers, 82 mm depth, 3 gaskets. With 44 mm triple glazing and Low-E achieves Uw = 0.8–0.95 W/(m²K). Recommended for new homes and renovations with controlled budget.

3. Alumil S77 Supreme Aluminium — For Architectural Projects

34 mm thermal break, Uf = 1.3 W/(m²K) at profile — fitted with triple glazing and Low-E achieves Uw = 1.0–1.2 W/(m²K). Ideal for large glazed facades, offices, commercial.

What to Always Ask For in Any Quote

In writing:

• Exact profile type (manufacturer, series, chamber count, depth)
• Ug of the glazing pack (not just "triple" or "Low-E")
• Spacer type (Warm Edge or standard — difference of 0.1–0.15 W/(m²K))
• Type of gas in the thermal chambers (argon = standard, krypton = premium)
• Hardware brand (Roto, Winkhaus, Maco — not "quality hardware")
• Type of installation included in price (standard foam or nZEB with pre-compressed bands)

Ask explicitly:

• Is installation with Illbruck or equivalent pre-compressed bands included?
• Are Blaugelb Triotherm+ preframes available and at what additional cost?
• What warranty do you offer separately on product and workmanship?

Signs That a Supplier Is Serious

Frequently Asked Questions

What technical criteria must advanced-insulation windows meet?

An advanced-insulation system must simultaneously meet: Uw ≤ 1.0 W/(m²K) (nZEB threshold), triple glazing with argon/krypton and Low-E (Ug ≤ 0.6), a PVC profile with min. 6 chambers or aluminium with a ≥ 34 mm thermal break, a Warm Edge spacer and RAL/nZEB-compliant fitting. Without all of these, the term is misused.

Which window profile has the best insulation in Bucharest?

Salamander bluEvolution 92 (6 chambers, 92 mm, Uf 0.9) with 52 mm triple glazing, argon, Low-E SGG and Warm Edge reaches Uw 0.66-0.8 W/(m²K) — passive-house performance. bluEvolution 82 offers the value balance with Uw 0.8-0.95, ideal for budget-controlled renovations.

What must I always ask for in any window quote?

Ask for it in writing: the Uw value of the complete window (not just the glass Ug), the profile type and number of chambers, the glazing type and fill gas, the presence of a Warm Edge spacer and the fitting method. Without these figures you cannot compare quotes correctly.

Why does standard double glazing not qualify as advanced insulation?

Standard double glazing has Uw = 1.3-1.6 W/(m²K), above the nZEB threshold of 1.0 W/(m²K). Advanced insulation requires triple glazing with two argon or krypton chambers and at least one Low-E layer, with a glass-unit Ug ≤ 0.6 W/(m²K).
