What Do uPVC Windows REALLY Cost in Your Situation?

Prices per frame (HR++ glass, standard white, including installation)

These prices are representative of the mid- to high-end segment, including sustainable profiles, certified installation, and full finishing.

Surcharges for extra options (corrected)

Example: Cost estimate terraced house (6 window frames + 1 door)

Optional surcharges (such as color foil, HR+++ glass or extra ventilation facilities) may increase this amount, depending on the chosen version.

The price of uPVC windows depends on a combination of technical, aesthetic, and logistical choices. jeofferte.nl advises clients to always pay attention to the cost drivers below when comparing quotes, as these together determine the final amount.

1. Frame Dimensions

• The larger the frame, the higher the material costs.
• Large glass surfaces require a stronger profile, heavier glass, and extra reinforcement.
• Non-standard or asymmetrical shapes (round, slanted, semi-circular) increase the price due to custom production.

Standard dimensions are cheaper to manufacture and install.

2. Window type (fixed, tilt-and-turn, sliding, door)

• Fixed windows are the most affordable (no hardware or hinges).
• Tilt-and-turn windows are slightly more expensive due to the mechanism.
• Sliding doors or French doors are the most expensive per m² due to complexity and weight.

3. Glass choice

• HR++ glass is standard and relatively inexpensive.
• HR+++ (triple) glass is more expensive, but more energy-efficient.
• Extra options such as safety glass, sound-insulating glass or sun protection significantly increase the price per m².

jeofferte.nl always specifies which type of glass is included in the quote.

4. Color and finish of the profile

• White smooth plastic is the most economical.
• Wood grain or color foil (e.g. anthracite, black) incurs additional costs of an average of € 30 – € 70 per m².
• Double-sided color (inside and outside) is more expensive than single-sided.

Dark colors sometimes require more UV-resistant foil or more reinforcement – this can also affect assembly costs.

5. Ventilation grilles and extra facilities

• Self-regulating ventilation grilles (mandatory for airtight homes) cost an average of € 30 – € 60 per linear meter.
• Insect screens, tilt-and-turn handles with locks, child safety locks, or integrated sun protection are optional costs.

6. Number of window frames and project scope

• The larger the project, the lower the price per window frame due to economies of scale.
• With a full home replacement, discounts of 5% to 15% are not uncommon.
• Small projects (< 3 window frames) can be more expensive per item due to fixed start-up and transport costs.

jeofferte.nl automatically takes project size and price scales into account when requesting a quote.

7. Installation and Accessibility

• Easily accessible facades (ground floor, detached) are cheaper to install than:
• Floors or apartments (scaffolding/lift required)
• Difficult-to-reach places (such as dormers)
• Dismantling of old frames, waste disposal, finishing, and adjustment work are often listed separately

8. Warranty, quality marks and service quality

• Suppliers with VKG or KOMO quality marks adhere to higher quality standards, which may slightly increase the price but also offer certainty.
• Extensive warranty conditions (10 – 15 years) can be an indication of higher material and assembly quality.

jeofferte.nl shows with every quote whether the partner works with certified systems and assembly protocols.

Summary – Key Price Determinants

jeofferte.nl always advises looking at the big picture, not just the price per square meter.
A slightly higher investment in profile or glass choice can lead to much greater savings or comfort gains in the long run.

Plastic windows are already a sustainable and low-maintenance choice, but with a smart approach you can save even more – both on the purchase and in the long term. jeofferte.nl shares concrete saving tips below that can be applied directly to new construction, renovation or partial replacement.

1. Always compare multiple quotes

Prices between suppliers can vary by as much as 20–30% for the exact same window sizes and glass choice. By comparing multiple quotes side by side, you will see:

• Where possible surcharges or discounts are located
• Which options are included as standard (e.g. ventilation grilles)
• Whether there are quality differences in profile or assembly

jeofferte.nl collects quotes from certified specialist companies so that you can compare directly in line with the market – without obligations.

2. Combine multiple frames in one order

The larger the project, the lower the price per frame. Many suppliers offer volume discounts for:

• Replacement of a complete front or rear facade
• Combination of windows and doors in one order
• Execution of multiple homes simultaneously (e.g. for homeowners' associations)

Tip: Don't delay replacing a single window for too long – having it replaced separately is relatively more expensive.

3. Opt for standard sizes and shapes

Customization (such as round, triangular, or unusually large frames) is more expensive in production and assembly. Standard rectangular sizes (e.g. 120x120 cm or 100x150 cm) are:

• Available faster
• More cost-effective
• Often with less production waste

jeofferte.nl helps you optimize your frame planning with smart sizing.

4. Choose functional glass – no more than necessary

Triple glazing (HR+++) is ideal for new construction or passive houses, but not always cost-effective for older houses with moderate insulation. In that case, HR++ with good ventilation and airtightness is sufficient.

Also note:

• Use soundproof glass only where really necessary
• Limit safety glass to the ground floor or doors

Ask jeofferte.nl for glass advice tailored to your home type and location.

5. Limit color and finish options to what is needed

Color foil (e.g. anthracite or wood grain structure) is often desired, but also a cost increaser. Consider:

• Color only on the outside (leave the inside white)
• One color for the whole house instead of different shades
• Smooth profile instead of wood grain if aesthetically acceptable

Savings: up to € 30–€ 70 per m².

6. Check for subsidies or reduced VAT rate

• When combining frame replacement with insulation measures, you may be eligible for the ISDE subsidy.
• For private homes older than 2 years, a reduced VAT rate of 9% on labor applies.
• Municipalities or provinces sometimes offer additional schemes for energy saving.

jeofferte.nl automatically takes into account eligible combinations when requesting a quote and informs you about your possibilities.

7. Choose a recognized company with a guarantee

Sometimes cheap providers seem attractive, but hidden costs (assembly, disassembly, finishing) and lack of guarantee lead to higher expenses in the long term. Choose:

• Suppliers with VKG quality mark or KOMO certificate
• Written guarantee of 10–15 years on material and assembly
• Clear quote without open items

Avoid repair costs afterwards by investing in quality up front.

8. Combine with other work

If you also want to renew gutters, facade cladding or roller shutters, for example, it is efficient and advantageous to have this done at the same time:

• Fewer call-out charges
• Better coordinated planning
• Sometimes combination discount possible with one supplier

jeofferte.nl makes it possible to intelligently bundle multiple jobs with a suitable professional partner.

Not all plastic windows are equal in quality. Differences in profile structure, glass, finish, installation and safety features can have major consequences in the long term for insulation, comfort, lifespan and ease of use. jeofferte.nl advises to carefully monitor the following quality aspects when assessing quotations or suppliers:

1. Profile quality and brand origin

Pay attention to the profile brand and the technical structure:

• Known brands: Schüco, Veka, Kömmerling, Rehau, Deceuninck (guarantee constant quality)
• Number of air chambers: at least 5 for HR++, 6 or 7 for HR+++ glass
• Profile class A (DIN EN 12608): thick-walled profile of top quality
• Reinforcement: galvanized steel or high-quality composite (important for strength and burglary resistance)

jeofferte.nl always states the profile brand, type and number of chambers in the quotation comparison.

2. Glass Quality and U-value

Check the insulation value and construction of the glass:

• U-value HR++: approx. 1.1 W/m²K
• U-value HR+++: approx. 0.5 – 0.9 W/m²K
• Note: warm-edge spacers and gas filling (argon/krypton) significantly improve performance
• Safety glass or soundproof glass requires extra quality requirements and certification

With triple glazing, pay attention to extra thickness and weight – not every profile or fitting is suitable.

3. Burglar Resistance and Fittings

High-quality frames are standardly equipped with:

• SKG-certified hardware (SKG* or SKG**)**
• Multi-point locking (usually 3 or 5 locking points)
• Core pulling protection and security cylinders (PKVW-compliant)
• Optional: laminated safety glass (P2A or P4A)

jeofferte.nl recommends always choosing an option that meets the Politiekeurmerk Veilig Wonen (Police Mark Safe Housing).

4. Colorfastness and foil quality

For colored or foiled frames:

• Use of Renolit foil or equivalent, UV-resistant foil
• Minimum 10-year colorfastness guarantee
• Uniform processing without bubbles, cracks or overlaps

Also pay attention to the method of processing:

• Cold welds and seams can come loose over time
• Professional workmanship is tight, seamless and even

5. Rubbers, sealing and ventilation

Good sealing is crucial for insulation and noise reduction:

• Use of high-quality EPDM or TPE rubber
• Minimum 2 closing levels (better: 3)
• Good connection to the wall prevents cold bridges
• Self-regulating ventilation grilles are a plus (Renson, Duco)

6. Installation Quality

Even the best window frames won't function properly without correct installation:

• Installation according to VKG or KOMO guidelines
• Use of durable sealing materials (e.g. compriband, EPDM foil)
• Window frame is placed horizontally and aligned with the inner wall
• Hinges and locks are adjusted and checked for closing force

jeofferte.nl only works with installation partners who are certified and have years of experience.

7. Certification and warranty conditions

Real quality window frames have:

• CE marking (European mandatory)
• KOMO quality mark (independent quality assurance)
• VKG quality mark (industry mark for plastic windows)
• SKG certificate (security class fittings)

In summary – checklist quality plastic windows

Via jeofferte.nl you can be sure that only reliable suppliers with demonstrable quality guarantees compete for your order.
