Summary Comparison

Note

The final price is influenced by, among other things:

• Type of glass (HR++ or HR+++)
• Color and finish
• Installation conditions (scaffolding, accessibility)
• Interior finishing and trim
• Number of frames per order (economies of scale)

jeofferte.nl facilitates the request and comparison of quotes from certified frame specialists, so you can objectively choose based on price, material, quality, and execution.

The price of window frames is determined by a combination of material properties, dimensions, finish, glass types, assembly complexity and quality levels. The emphasis may differ per type of material (plastic, wood, aluminum), but the factors below are relevant in almost all cases.

1. Choice of material: plastic, wood or aluminum

• Plastic is usually the cheapest, with a competitive price-performance ratio.
• Wooden frames are more expensive to purchase and require periodic maintenance.
• Aluminum frames are the most expensive per m², especially for large windows, but require no maintenance.

jeofferte.nl shows the difference in price and lifespan per material type for each quote.

2. Dimensions and design of the frame

• Large frames require more material and heavier glass (especially with triple or safety glass).
• Deviant shapes (round, oblique, triangular) are more expensive because of custom production.
• A fixed window is cheaper than a turn/tilt window or sliding door, because of less hardware and simpler assembly.

3. Type of glass and insulation value

The type of glass has a major impact on the total price:

jeofferte.nl clearly indicates which glass is included and what any additional costs are per room or facade.

4. Color and finish of the frame

• Standard white is the most economical for plastic and aluminum.
• Color foil or textured lacquer increases the price by an average of € 60 – € 240 per m².
• Inside and outside both colored is more expensive than just the outside.

For wood, the costs depend on:

• Lacquered or delivered blank
• Single or multi-layer treatment
• Wood type (spruce, meranti, afrormosia)

5. Hardware, security and ventilation

• SKG-certified hardware with multi-point locking and core pull protection is slightly more expensive, but highly recommended.
• Ventilation grids (mandatory for airtight homes) cost € 60 – € 120 per meter extra.
• Child-safe handles, fall protection and automatic window openers increase the price for custom applications.

6. Number of frames and economies of scale

• For larger orders, the price per frame decreases (production and assembly logistics more efficient).
• Replacing a single frame is relatively more expensive than an entire facade or house at once.
• jeofferte.nl offers customized quotes, where economies of scale are automatically calculated.

7. Installation conditions and accessibility

• Frames on the ground floor are quicker and cheaper to install than on an upper floor.
• Extra costs arise in the case of:
• Scaffolding or telehandler required
• Poor accessibility or indoor installation
• Removal of old frames, disposal, preparatory work and interior finishing

jeofferte.nl clearly states whether accessibility, demolition or finishing are included in the price.

8. Guarantee, certification and installation level

• Products with KOMO quality mark, VKG certificate or SKG fittings are slightly higher in price, but offer long-term security.
• Affiliated installation companies work according to guidelines for sealing, waterproofing, and installation tolerances – this translates into durable performance, but sometimes higher labor costs.

In summary – key price factors per category

jeofferte.nl helps clients to compare price factors transparently, so that you don't just decide based on the total amount, but also on content, specifications and long-term return.

1. Plastic frames – white profile, HR++ glass, standard finish

Plastic frames are low-maintenance and relatively inexpensive to purchase and install. Variants with wood-look structure and colored foil are also available at jeofferte.nl.

2. Wooden frames – hardwood, lacquered, HR++ glass

Wooden frames offer a warm appearance and high insulation value. Please note that periodic painting is required. jeofferte.nl only works with certified hardwood (FSC/PEFC).

3. Aluminum frames – insulated profile, HR++ glass

Aluminum frames are extremely durable, dimensionally stable and very suitable for large windows or modern architecture. jeofferte.nl exclusively supplies thermally broken systems with CE marking.

Summary – price comparison per material type

jeofferte.nl delivers custom quotes per material type, tailored to profile type, glass choice, color, finish and installation situation. By comparing multiple quotes, you get a clear insight into costs, benefits and long-term value.

The choice for new frames is a significant investment, regardless of the material chosen. Whether you choose wood, aluminum or plastic, there are several ways to save specifically – without compromising on quality or comfort. jeofferte.nl lists the most important saving tips per material type.

1. General saving tips for all types of frames

Always compare multiple quotes

Prices can differ up to 30% with equal specifications. Via jeofferte.nl you can easily compare multiple providers on price, profile quality, glass, finish and warranty.

Combine multiple frames in one project

The larger the project volume, the lower the price per frame. So preferably combine all frame replacements in one assignment moment.

Choose standard sizes where possible

Deviating shapes or large frames lead to higher material costs and production time. Standard rectangular sizes are more economical.

Consider glass combinations per facade

HR+++ (triple glazing) is not necessary in every room. In many cases, HR++ is sufficient in bedrooms or upper floors. Also, safety glass does not need to be applied everywhere.

Have old frames removed in consultation

Some suppliers charge extra costs for demolition and disposal. Ask if you can prepare this yourself to reduce costs, provided this is responsible.

Check subsidy opportunities

When replacing frames in combination with insulation (glass or walls), you may be eligible for the ISDE subsidy or local regulations. jeofferte.nl automatically takes this into account.

2. Specific saving tips for wooden frames

• Choose transparently finished wood (e.g. larch or pine) instead of expensive opaque paint finishes.
• Have frames delivered primed and paint them yourself for lower production costs.
• Prevent frequent maintenance by choosing hardwood types with FSC or KOMO certification.
• Consider wood-aluminum for rear facades (wood inside, aluminum outside) for long life without exterior painting.

3. Specific savings tips for aluminum frames

• Opt for standard RAL colors: Deviating colors or matte structures can be up to 15% more expensive.
• Combine aluminum only on visible sides (for example, only the facade or storefront) and choose plastic or wood elsewhere.
• Pay attention to the insulation value of the profile: thermally broken profiles are slightly more expensive but quickly pay for themselves in energy savings.
• Take into account larger spans: aluminum is suitable for large window frames, so you can use fewer mullions – that reduces material costs per m².

4. Specific saving tips for plastic window frames

• Choose white smooth profile instead of colored or wood grain structure for direct material discount.
• Limit color foil to the outside (leave the inside white) to save up to € 50 per m².
• HR++ glass is energy efficient enough in most situations – triple glazing is only profitable with well-insulated facades.
• Combine the project with door replacement (back door, front door) for economies of scale in production and installation.

5. In summary: How to save purposefully

jeofferte.nl helps you put together an efficient window solution that suits your home type, budget and finishing wishes. By comparing quotes at a detailed level, you can immediately see where the greatest savings opportunities lie, without sacrificing quality.
