🔧 Same Hardware, Different Surface
Both windows require the exact same perimeter mechanism, the same handle, the same hinges and roughly the same manufacturing time. The large window simply uses a bit more aluminium and glass.
How Much Do Aluminium & PVC Windows Cost? (Indicative prices per m²)
It is by far the first and most pressing question every customer asks: "How much per square metre for aluminium windows?" It is perfectly reasonable to want to estimate your renovation budget.
However, if a professional gives you a flat "per metre" price over the phone without knowing exactly what you need, you should probably worry. Windows are not sold like tiles or carpet. Let us see why per-m² pricing is a major trap, along with realistic price ranges so you know where the market stands today.
1. Why "Price per Square Metre" Is a Trap (The Bathroom Example)
To understand the misconception, picture a small bathroom window (0.50 m × 0.50 m = 0.25 m²) and a large living room window (1.00 m × 1.00 m = 1.00 m²).
📐 The Maths of the Trap
If the living room window costs €350 (i.e. €350/m²), the small bathroom window will not cost €87 (one quarter). It will cost roughly €250 because of the fixed hardware and labour costs. Divide that: €250 ÷ 0.25 m² = €1,000/m²!
📊 A Rough Guide, Not a Calculation Tool
Price per m² is merely a whole-house average - useful as a first budget indicator but unsuitable as a pricing tool for individual openings. The correct approach is always a total project quotation.
2. Indicative Market Prices (Average)
The prices below are indicative averages for the Greek market, covering standard sizes in white colour. They include energy-rated glass and typically exclude 24% VAT, roller shutters, insect screens and removal/installation costs.
🏠 PVC (Synthetic)
The "king" of value for money. Outstanding thermal insulation at a much lower production cost. €150 – €250/m². Ideal for tight-budget renovations, holiday homes, rental apartments or very cold regions.
🔩 Thermal-Break Aluminium (Casement)
The standard for modern homes. Polyamide-bridged profiles for excellent insulation and top-tier durability. €300 – €450/m². Ideal for primary residences, owner-occupied homes and "Exoikonomo" subsidy projects.
🚪 Thermal-Break Aluminium (Sliding)
Save indoor space, though slightly less airtight than casement windows. €350 – €500/m². Ideal for living rooms with limited space or older renovations with existing recessed tracks.
💎 Premium Systems (Lift & Slide / Minimal)
The ultimate luxury: vast glass surfaces, concealed tracks and mechanisms that lift 300 kg sashes. €550 – €850+/m². Ideal for new-build villas, penthouses with views and demanding architectural applications.
3. What Can Skyrocket the Final Quote?
If you estimated costs using the ranges above but the quote you received is 30% higher, check these three parameters before blaming the manufacturer.
🎨 Colour
The prices above are for classic white. If you request wood-look finishes, dark anthracite (Sablé/Matt) or metallic shades, costs immediately rise by 20% – 30%. In many projects, this "aesthetic" upgrade represents the single biggest price deviation.
🔄 Extras (Shutters & Screens)
A roller shutter (especially PU-filled aluminium with an electric motor) often costs as much as the window itself! A pleated screen can add another €80 – €120 per opening. Many customers forget to ask whether the initial quote includes or separately charges these items.
🪟 Glazing
Upgrading from standard energy double glass to triple glazing (for superior sound insulation) or security glass (laminated / triplex) noticeably increases the per-m² price. These upgrades are worthwhile in specific applications (ground floors, noisy streets) but are not always necessary.
4. In Summary: Request a Full Project Quotation
Next time you request a quote, avoid the question "how much per metre". The right approach is to ask for a total project quotation.
📏 Provide Exact Dimensions
Invite the manufacturer to your site or provide approximate Width × Height measurements for each opening. Tell them exactly what you want: "I want thermal-break, anthracite, with screens and electric shutters." Request a detailed, written quotation that breaks down every component separately.
⚖️ Compare Apples to Apples
Collect at least 3 written quotations and make sure you are comparing identical specifications: same profile series, same glazing, same hardware. Only then can you see who is genuinely giving a fair price and who is cutting corners in critical areas. Price per metre means nothing without a detailed breakdown.
