What does HR glass cost and what should you look out for regarding the price?

1. What is HR++ glass?

HR++ glass consists of two panes of glass with a cavity between them, filled with noble gas (usually argon) and equipped with a heat-reflecting coating. This makes the glass significantly better insulating than standard double glazing (U-value approx. 1.1 W/m²K versus 2.8 for thermopane).

Applications:

• Existing frames (wood, plastic or aluminum)
• Homes older than 2 years (due to VAT advantage)
• Both renovation and new construction

2. Average price per m² (including VAT and installation)

Prices include measurement, installation, caulking and VAT. For small orders (less than 1 m²) there is often a minimum charge of €100 – €150.

3. Cost examples per situation

For larger projects, the average price per m² decreases due to economies of scale in transport, labor, and material processing.

4. What is included in the price?

• Custom HR++ glass including cavity filling and coating
• Removal of old glass and disposal
• Measurement and installation by certified glass company
• Sealing and finishing

5. Possible additional costs

6. Subsidy and tax benefits

ISDE subsidy (Investment Subsidy for Sustainable Energy):

• Conditions:
• Minimum 8 m² HR++ glass
• Performed by a recognized professional company
• Combined with a second insulation measure (such as floor insulation)
• Reimbursement: up to approx. €23 per m²
• Total savings: €180 – €230 for 8 – 10 m² HR++ glass

9% VAT on labour

For homes older than 2 years, the labour portion of the invoice is taxed at 9% VAT instead of 21%. This is automatically calculated in most quotes via jeofferte.nl.

7. Saving tips for HR++ glass

• Combine multiple panes in one order to save on installation costs
• Choose standard sizes if custom sizes are not necessary
• Avoid rush fees by planning in advance
• Check subsidy options in advance
• Compare multiple quotes via jeofferte.nl for insight into price-quality ratio

Summary

The average cost of HR++ glass, including installation, ranges between €115 and €145 per m², depending on version and circumstances. With additional options such as safety glass or sun-blocking coatings, this can increase to €200 per m². With subsidies and tax benefits, the net investment is considerably lower. An accurate comparison via jeofferte.nl helps in selecting a recognized glass company with transparent prices and high quality.

Summary

The price for glass replacement including installation and VAT varies from approximately €100 for a small single-pane replacement to over €1,000 for large HR++ or HR+++ projects on upper floors. Most standard HR++ replacements cost between €120 and €160 per m². With subsidies and tax benefits, the net amount is significantly reduced. Via jeofferte.nl, you will receive transparent quotes from accredited glass companies with a full price breakdown and clarity on any additional costs.

1. Glass type and composition

The type of glass is the basis for the price per square meter. The more layers, treatments, or safety features, the higher the cost.

Multi-layer structure, coatings, and gas filling make HR glass more expensive than standard options.

2. Dimensions and shape

The price per m² is influenced by:

• Surface area: Smaller panes are relatively more expensive due to fixed installation costs.
• Unusual shapes: Round, triangular, or trapezoidal panes are more difficult to produce and install.
• Glass thickness: Thicker glass is more expensive, especially with laminated or sound-insulating glass.

Example:
A rectangular HR++ pane of 1.2 m² costs on average €160.
A round pane with the same surface area can cost €200 or more due to extra labor.

3. Machining and extra features

Glass with additional features or finishes incurs higher material costs:

These extras are optional, but may be highly recommended depending on the location (such as south-facing or ground floor).

4. Installation Conditions

The accessibility and complexity of the installation location also influence labor costs:

A recognized glass company assesses these aspects during measurement or prior to the quote.

5. Number of panes and project scope

The larger the project, the lower the price per m² due to economies of scale:

• Single pane: often starting price of €100 – €150
• 4 to 8 m² HR++ glass: favorable price per m²
• More than 10 m²: possibility of volume discount or reduced installation costs

Tip: Combine multiple windows or have glass in the front door, back door, or bathroom replaced at the same time.

6. Urgency and Time of Execution

• Urgent repair (within 24 hours): surcharge of 10% to 25% on normal price
• Emergency provision (plexiglass or carpentry): €150 – €300 extra
• Weekend or evening work: hourly rate can amount to €75 or more

For non-urgent damage, it is preferable to wait until a regular working day to limit costs.

7. Market Conditions and Availability

External factors can temporarily affect the glass price:

• Raw material prices (such as lime and soda for float glass)
• Gas and energy prices (glass production is energy-intensive)
• Transport costs and risk of breakage
• Seasonal demand (higher demand during energy efficiency campaigns)

Price increases are particularly noticeable for HR+++ and custom glass, where longer delivery times occur.

8. Subsidies and tax advantages

Although these factors do not directly affect the gross quote price, they do reduce the final net costs:

• ISDE subsidy:
• Minimum of 8 m² HR++ or 6 m² HR+++ glass required
• Only valid if carried out by a recognized professional company
• Reimbursement up to approximately €23 – €65 per m²
• 9% VAT on labour for homes older than 2 years

• Automatically processed in the quote or final invoice

Summary: What determines the price of glass?

The price of glass is determined by a combination of:

• The glass type and any treatments
• The shape, size, and location of the pane
• Installation conditions and accessibility
• The size of the project (more = cheaper per m²)
• Urgency or custom applications

A good glass quote takes all these factors into account. Via jeofferte.nl, you can quickly gain insight into current rates, technical possibilities, and available subsidies from recognized glass companies. This way, you avoid surprises and make a well-founded choice.

1. What is the ISDE subsidy?

The ISDE is a scheme from the Central Government (executed by RVO) and focuses on:

• Private homeowners
• Insulation measures (glazing, roof, floor, facade, crawl space)
• Purchase of sustainable installations (such as heat pumps and solar water heaters)

For glass replacement, only HR++ or HR+++ glass is eligible, provided that specific conditions are met.

2. Conditions for subsidy on HR++ or HR+++ glass

3. Subsidy amounts per glass type (2025)

Note: With only one insulation measure (only glass), the subsidy amount may be halved. Combining it with, for example, floor insulation or wall insulation will result in the maximum amount.

4. What exactly is reimbursed?

The subsidy applies to:

• The glass materials (HR++ or HR+++)
• Potentially required new frames (often mandatory for HR+++ glass)
• The labor costs, provided they are specified
• Only panes that directly border the outside air

No subsidy is possible for:

• Interior doors or interior glass
• Single glazing or standard double glazing
• DIY installation

5. How do you apply for the subsidy?

Step 1 – Have the glass installed

Ensure installation by a recognized glazing company. Quotes via jeofferte.nl meet this condition.

Step 2 – Gather documents

You will need:

• Invoice with glass surface area, type of glass, and labor costs
• Proof of payment
• Optional: quote or invoice for a second measure (for combined applications)

Step 3 – Apply for the subsidy online

You will receive a message about approval and payment within 8 weeks.

6. Example situation with maximum subsidy

Project:

• 16 m² HR++ glass
• 50 m² floor insulation
• Both installed by a certified company

Glass costs: approx. €2,100
Floor insulation costs: approx. €1,800
Total subsidy:

• HR++ glass: 16 m² × €23 = €368
• Floor insulation: 50 m² × approx. €7 = €350
• Total subsidy: €718

Net cost after subsidy: €3,182 instead of €3,900
Savings: approx. 18%

7. Important Points

• You must live in the home yourself at the time of application.
• A subsidy can only be applied for after execution and payment.
• You can also carry out one measure first, and add a second measure within 24 months.
• Combination with other schemes (such as the reduced VAT rate on labor) is permitted.

Summary

The ISDE subsidy makes investing in HR++ or HR+++ glass considerably more attractive. With sufficient glass surface area and a second insulation measure, you will receive up to €23 per m² for HR++ glass and up to €65 per m² for HR+++ glass. The subsidy only applies if carried out by a qualified glazing company. Via jeofferte.nl, you will receive quotes from recognized companies, with clear details of surface area, glass type, and labor costs – everything you need for a successful subsidy application.

1. Insulation value of HR++ glass

HR++ glass consists of two panes of glass with an inert gas (usually argon) and a heat-reflecting coating in between. This considerably reduces heat loss through windows.

The lower the U-value, the better the glass insulates. HR++ glass offers up to 80% better insulation than single glazing, and approximately 60% better than old double glazing.

2. Annual energy saving

The energy saving depends on the current type of glass, the glass surface area in the home and the type of heating. The table below provides an indication for an average terraced house with 20 m² of glass surface area.

* Based on average gas consumption in a standard situation (terraced house, central heating boiler, normal ventilation)

For larger homes or more glass surface area (such as corner houses or detached houses), the savings will naturally be greater.

3. Costs and payback period

The average price of HR++ glass including installation is between €115 and €145 per m². For a home with approximately 20 m² of glass surface area:

• Total investment: approx. €2,500 – €2,900
• Annual savings: €150 – €330 (depending on the initial situation)
• Expected payback period: 7 to 10 years

With rising energy prices, the payback period may become shorter.

4. Subsidy and tax benefit

HR++ glass is eligible for the ISDE subsidy, provided the following conditions are met:

• Replacement of at least 8 m² of HR++ glass
• In combination with a second insulation measure (such as roof, floor, or cavity wall insulation)
• Carried out by a certified glass company

Extra benefit: For homes older than 2 years, the reduced VAT rate of 9% on labour applies, which further lowers the investment.

5. Comfort Improvement and Additional Benefits

In addition to direct savings on your energy bill, HR++ glass offers the following benefits:

• Less draught and cold spots near windows
• Reduction of condensation on the inside of the glass
• Noise reduction compared to single glazing
• Increased property value (energy index)
• Lower CO₂ emissions and more sustainable housing

When combined with laminated glass, HR++ also provides an improvement in safety against burglary and injury.

6. Example Scenario: Savings in Practice

Situation:

• Terraced house with 18 m² single glazing
• Replacement with HR++ glass by a recognized professional company
• Energy price: €1.20 per m³ of gas

Result:

• Gas savings: approx. 250 m³ per year
• Cost savings: approx. €300 per year
• Subsidy when combined with floor or roof insulation: approx. €400
• Net investment (after subsidy and VAT advantage): approx. €2,300
• Payback period: approx. 7.5 years

Summary

HR++ glass offers an excellent balance between investment and return. The annual savings on heating costs can amount to up to €330 per year, especially when replacing single glazing. In combination with subsidies and a reduced VAT rate, the payback period is relatively short. In addition, you increase the living comfort, safety, and energy performance of the home. An application via jeofferte.nl will provide you with quotes from recognized glass companies that can professionally advise and guide you in this matter.

1. Choose glass that matches the function and location

Not every window needs the same type of glass. By choosing glass based on the actual function and position, you save quickly:

Tip: Get advice from a certified glazing company via jeofferte.nl about what is technically really necessary.

2. Combine multiple panes in one order

The biggest savings come from efficiently utilizing labor and call-out charges:

• Have multiple windows or doors fitted with new glass immediately
• Combine damage repair with insulation upgrade (e.g., HR++ in the front door)
• Discuss a joint approach with neighbors or co-residents of an apartment complex

A larger order lowers the average price per m² and avoids double costs for transport or assembly.

3. Choose standard sizes and rectangular shapes

Customization – such as round or trapezoidal glass, special thicknesses, or cutouts – increases the price by 15% to 30%. If possible, choose:

• Rectangular dimensions
• Glass thicknesses that are standardly available (such as 4-15-4 mm HR++)
• No extra cutouts for grids or decorative strips (unless necessary)

This keeps production simple and cheaper.

4. Plan ahead to avoid rush surcharges

Emergency repairs, emergency provisions and evening or weekend work cause significant additional costs:

If the situation allows: secure the opening temporarily and schedule assembly on a weekday.

5. Make use of available subsidies

When replacing outdated glass with HR++ or HR+++ glass, you may be eligible for:

ISDE subsidy (Investment Subsidy Sustainable Energy)

• Conditions:
• Minimum 8 m² HR++ or 6 m² HR+++ glass
• Combination with a second insulation measure (such as roof or floor insulation)
• Carried out by a recognized professional company
• Compensation: up to €23 – €65 per m²

A recognized glazing company via jeofferte.nl can inform you about the requirements and, if desired, help with the subsidy application.

6. Take advantage of the reduced VAT rate

For homes older than 2 years, the low VAT rate of 9% applies to the labor portion of the glass replacement. Example:

This tax benefit is automatically settled with quotations from recognized companies.

7. Compare multiple quotes from recognized glazing companies

The rates and working methods of glaziers vary greatly, even with the same specifications. When comparing, pay attention to:

• What is included (removing old glass, disposal, sealant work)?
• Are the glass thicknesses and insulation values clearly stated?
• Is the work carried out by a certified glazing company?
• Is VAT and subsidy benefit taken into account?

Via jeofferte.nl you will receive transparent and competitive offers from companies that meet current standards.

Summary: efficient savings on glass replacement

By cleverly combining these strategies, you reduce the net investment in glassware without compromising on quality, safety or energy savings.

1. Always have glass installed by a certified glazier

For correct installation and the right to warranty, insurance, or subsidies, it is important that the work is carried out by a qualified company:

• Only certified glaziers are allowed to install HR glass while maintaining the manufacturer's warranty.
• For ISDE subsidies, execution by a certified professional company is mandatory.
• For insurance claims for glass damage, a detailed invoice or report prepared by an accredited party is required.
• Installation errors (such as incorrect placement, cold bridges, or stress differences) can lead to condensation, cracks, or leaky panes – without the right to compensation.

Via jeofferte.nl, quotes are exclusively provided by verified and skilled glass companies, ensuring professional execution.

2. Pay attention to standards and safety requirements (NEN 3569)

When using glass in doors, windows down to the floor, or areas with a risk of falling, safety glass (laminated or tempered) is mandatory. Glass that does not comply with the NEN 3569 standard can have legal and insurance consequences in case of injury or damage.

Check with every quote whether the correct type of glass is proposed. A recognized glass company will actively point this out to you.

3. Always consult with the insurer in advance in case of damage, unless there is acute danger

In case of damage that does not pose a direct danger (such as a cracked window without an open break) it is advisable to contact your insurer first before installation:

• This prevents costs from falling outside of coverage.
• In many cases, a quote or photo evidence is required in advance.
• In case of urgent damage, you may act immediately, provided you keep photos and proof for later submission.

A glass company familiar with insurance claims handling – such as the affiliated companies at jeofferte.nl – can guide you through this.

Summary

For every glazing job, large or small, skilled execution is crucial for safety, financial coverage, and the long-term performance of the glass. Therefore, work exclusively with certified glazing companies, verify that the correct standards are met, and always consult with your insurer in advance in case of damage, if the situation allows. This way, you prevent misunderstandings, unnecessary costs, or unpleasant liability issues.
