What Does a uPVC Window Cost and Where Do the Price Differences Come From?

Prices are based on white or cream-colored plastic frames (inside and outside the same), equipped with HR++ glass, SKG** hardware, standard ventilation grilles where necessary, including full installation and finishing.

What influences the price per m²?

• Frame type: Fixed windows are the most affordable per m². Moving parts (turning/tilting/sliding) increase the price.
• Profile quality: A-quality with steel reinforcement and high insulation value is more expensive than B-quality systems.
• Colour and texture: White frames are the cheapest. Exterior foils in colour or wood grain texture incur an additional cost of +10% to +20%.
• Glass choice: HR+++ or safety glass significantly increases the price per m² (see below).

Surcharges per option (indicative per m²)

Practical example: standard tilt-and-turn window

A 100 x 120 cm plastic tilt-and-turn window (1.2 m²) costs on average:

• Base price: 1.2 m² × € 850 = € 1,020
• Including HR++ glass, SKG** hardware, installation, finishing

With HR+++ glass and exterior colour, this can increase to approx. € 1,250 – € 1,350 per frame.

jeofferte.nl collects requests and connects them to recognized suppliers of plastic window frames. In their quotes, price differences per square meter are often broken down by window function, color, and glass type, giving you clear insight into the price structure.

These amounts are based on plastic frames in standard white or cream, with HR++ glass, SKG** fittings, ventilation grids where necessary, and complete assembly including finishing. Disassembly and removal of old frames are included.

Possible additional costs per project

Example – Terraced house (8 frames, standard HR++)

• 4 × tilt and turn windows (100 x 120 cm)
• 2 × fixed windows (150 x 100 cm)
• 2 × combination frames (180 x 120 cm)
• Total glass surface: ± 17 m²
• Including demolition of old frames, finishing, hardware, grilles

Total price indication: € 8,500 – € 10,500

With HR+++ glass and color outside, this can increase to approx. € 12,000 – € 13,000.

Important notes

• Prices may vary in the event of large deviations in dimensions, special shapes (round, trapezoid), or in the case of frames in dormer windows and conservatories.
• In the case of renovation, it is important whether existing interior finishing is retained or needs to be replaced.
• Subsidy via the ISDE is possible when installing HR++ or HR+++ glass with new frames and a second insulation measure (such as floor insulation).

jeofferte.nl collects requests and connects them to experienced suppliers of plastic windows. By receiving multiple customized quotes, you can easily compare per project content, material and execution and make targeted choices.

1. Type of window frame and window function

The base price differs per function of the window frame. The more moving parts, the higher the price.

2. Dimensions and Shape

Standard sizes are more advantageous. Deviating sizes, arched shapes, round windows, or sloping corners require customization and increase production costs.

• Large windows or frames are more economical per m².
• Small windows are relatively more expensive per m² due to fixed assembly and material costs.

3. Color and Structure

White or cream-colored frames (standard) are the most economical. Color foils and wood grain structures increase the price significantly.

4. Glass selection

HR++ glass is included as standard. HR+++ (triple) or special glass (safety or soundproof) entails significant additional costs.

5. Profile quality and brand

The quality of the plastic profile has a major influence on lifespan, insulation value and price. A-brands are more expensive, but offer higher stability, UV resistance and certifications.

• A-quality with steel reinforcement: higher in price, better in the long term
• B-quality: cheaper, but often lower performance and less warranty

6. Hardware and Locks

Standard SKG** is usually included. Burglar-resistant fittings (SKG***), additional locks or multi-point locks increase the price.

7. Ventilation facilities

Grilles are required when replacing without mechanical ventilation. There are standard and advanced variants:

8. Mounting conditions

The mounting situation has a direct impact on labor costs:

• Accessibility: Floor, dormer or rear facade without free passage incurs additional costs (scaffolding, extra working hours).
• Demolition of old frames: If old frame is heavily weathered or not demountable, extra work is required.
• Repair work: Renewing masonry, plasterwork or interior finishing incurs additional costs.

9. Interior finishing and extra options

Standard finishing (slats, sealing) is usually included. Custom-made box constructions, window sills or painting increase the price.

10. Number of frames and scale

A larger order (e.g. entire house) reduces the average price per frame due to shared labor costs, discounts on material and efficient planning. Smaller orders or individual windows are relatively more expensive.

jeofferte.nl enables clients to compare quotes from multiple specialists, where the above factors are often specified separately. This makes it easier to gain insight into what is included or not included, and where cost differences come from.

The subsidy includes replacement of the window frame, provided it is carried out by a construction company or glazier with KvK registration. The glass installation must take place in combination with a new window frame. Separate glass installation in an existing window frame is not eligible.

Conditions (2025)

• You are the owner and resident of the property (private individual).
• The property is at least 2 years old (not a new build).
• You are replacing at least 8 m² of glass + frame.
• The glass meets the minimum insulation value (U-value ≤ 1.2 W/m²K for HR++, ≤ 0.7 W/m²K for HR+++).
• The work is carried out by a professional party.
• You combine the measure with at least one other insulation measure (such as roof, facade or floor insulation).
  → Only then will you receive the full subsidy amount per m².
• If you only carry out one insulation measure, the amount will be halved (for example, € 26.50 per m² for HR++).

Maximum subsidy amounts per dwelling type (indicative)

These are indicative amounts. The actual subsidy depends on the exact number of m², the glass level, and whether a second measure is being implemented.

What is not subsidized?

• Replacement of only the glass without the frame.
• Door frames or sliding doors (usually excluded).
• Glass with too low insulation value or without a recognized label.
• Self-performed work (do-it-yourself does not count).

Application procedure

1. Have the work carried out and pay the full invoice.
2. Collect invoices, proof of payment and technical data (U-values, glass sheet, surface).
3. Apply for the subsidy digitally via rvo.nl within 24 months after execution.
4. RVO assesses your application and pays out within 8 weeks.

jeofferte.nl connects your request to professionals who have experience with subsidy-eligible execution and can provide you with invoices and specifications that are required for a valid ISDE application.

1. Combine multiple windows in one order

The larger the order, the lower the price per window. Specialists generally give discounts for larger volumes, because installation is planned more efficiently and material costs are more favorable in larger quantities.

Tip: Plan one project for all facades, including back and floor, instead of phased placement.

2. Choose standard colors and profiles

White or cream windows are considerably cheaper than colored foils. Exterior foil in color or with wood structure increases the material costs by 10–30%.

• Preferably choose single-color profiles (inside and outside the same).
• Avoid exclusive structures (anthracite grain, metallic look) if saving is desired.

3. Limit the number of tilt and turn windows

Moving parts make the frame technically more complex and therefore more expensive. Where possible, you can include one or more fixed windows instead of a full tilt and turn system.

A fixed window is on average € 150 – € 250 cheaper than a tilt and turn window of the same size.

4. Have HR++ glass installed instead of HR+++

Triple glazing (HR+++) offers extra insulation, but requires adapted profiles and involves a substantial additional cost. In many homes HR++ is sufficient for energy saving and meets the requirements for ISDE subsidy.

5. Avoid unnecessary options

Consider carefully whether extra options are necessary:

• Self-regulating ventilation grilles are more expensive than manual models.
• Insect screens and tilt-and-turn restrictors are useful, but can also be added later.
• Custom interior finishing (e.g. window sills or box constructions) can often be done more cheaply by a carpenter.

6. Request in the low season

In quiet periods (spring or autumn), some window frame specialists use sharper rates. The planning is also often more flexible, which can be advantageous for projects with multiple rooms or floors.

7. Repair or preserve existing finish where possible

If the existing interior finish (window sill, box, slats) can be retained, you avoid extra costs for demolition and new carpentry.

8. Request multiple quotes via jeofferte.nl

By comparing multiple specialists on content and price, you can see which party includes which options, and you can make informed choices. Price differences for the same quality can be as high as 20–30%.

9. Pay attention to subsidy conditions

Combine the replacement of window frames with HR++ or HR+++ glass and a second insulation measure (such as roof or floor insulation) to receive the full ISDE subsidy amount. With only one measure, the amount is halved.

10. Choose proven profile systems

Cheaper, unknown brands may seem attractive in the short term, but often offer less warranty, poorer UV resistance and faster discoloration. An A-brand with a warranty of 10–15 years is more economical in the long term.

1. Specification of the window frames

Check if the dimensions, window types, and layouts are correctly recorded:

• Are the width and height correct per window frame?
• Are fixed windows, tilt-and-turn windows, or combinations indicated correctly?
• Are the correct rooms named (e.g., living room, bedroom, kitchen)?

Tip: If necessary, send a floor plan or photos with the request.

2. Profile type and brand

Not every plastic profile is of the same quality. Pay attention to:

• Is it an A-quality profile (e.g., VEKA, Schüco, Kömmerling)?
• Is steel reinforcement included?
• What is the profile structure and insulation value (U-value)?

An unknown or B-brand can be considerably cheaper, but also less durable, poorly UV-resistant, and difficult to replace.

3. Glass choice and performance

A quote must clearly state:

• HR++ or HR+++ (triple glazing)?
• U-value of the glass (insulation value)?
• Safety glass or sound-insulating glass where necessary?

Note: Not all glass is standard burglar-resistant or injury-safe. Check if the type of glass suits the function of the room.

4. Color and finish

Is the color included or optional? Quotes can vary greatly in this regard.

• White or cream is often standard
• Exterior foil (color) can be up to 20% more expensive
• Different colors inside/outside are custom

Explicitly ask about additional costs for color deviations.

5. Hardware and Locks

Ensure the security level is clear:

• Is SKG** or SKG*** standard?
• Multi-point locking included?
• Does the quote include anti-burglary protection (core pulling)?

For front doors and ground-floor windows, at least SKG*** with anti-burglary protection is recommended.

6. Ventilation Grilles

Are grilles included? And what type?

• Manually operated, self-regulating, or sound-dampening?
• How many grilles are included and in which frames?

If there is no mechanical ventilation, grilles are often structurally required.

7. Installation and Finishing

The quality of installation determines the lifespan and airtightness. Check if the following are included:

• Demolition of old frames and disposal?
• Connections with inner wall, plaster or windowsill?
• Finishing with trim, sealant and adjustment?

Tip: If in doubt, ask for photos of similar completed projects.

8. Warranty Conditions

Compare the warranty per component:

Note the small print: with poor maintenance or painting, the warranty sometimes expires prematurely.

9. Subsidy Eligibility

Is the frame suitable for subsidy (ISDE)? This must be evident from:

• Insulating glass with sufficient U-value
• Certified installation by an accredited party
• Mention of surface areas per window (for subsidy application)

Explicitly ask for technical specifications if you want to apply for a subsidy.

10. Transparency of Additional Costs

Are extra options and choices specified or hidden in one total amount?

• Is the price per ventilation grille or color variant listed separately?
• Are provisional sums or fixed prices used?
• Are additional works (e.g. plaster repair) excluded or included?

A good quote lists all components separately and does not exclude essential items.

jeofferte.nl encourages specialist contractors to submit specified quotations in which the above-mentioned elements are individually named. This provides insight per frame, function, and execution, allowing the client to make choices based on substance – not just on total price.
