How much does it cost to install HR++ glass?
Installing HR++ glass costs on average between €80 and €100 per square metre, including installation. For a standard project of 5 to 6 square metres, you will pay between €500 and €700 in total.

Costs of HR++ glass per type
The costs for HR++ glass depend heavily on the type of glass you choose. Standard HR++ glass is the most affordable, while sun-resistant glass and safety glass are more expensive due to extra properties such as heat resistance or burglary protection.
| Type of HR++ glass | Price per m² | Project price (5-6 m²) |
|---|---|---|
| HR++ (standard) | €80-100 per m² | €500-700 |
| HR++ extra sun-resistant | €150-170 per m² | €700-900 |
| HR++ safety glass | €130-160 per m² | €650-850 |
Price-determining factors for installing HR++ glass
The costs for installing HR++ glass vary per situation. This is because several factors influence both the material and the labour time. Below you can read which elements determine the total price.
Type of glass
Standard HR++ glass is the most affordable option. If you choose extra sun-resistant glass, you pay €150 to €170 per square metre. For safety glass, the costs are between €130 and €160 per square metre. Both variants require more material and processing time, which increases the price.
Glass thickness
Thicker HR++ glass designs cost about €40 per square metre more than standard glass. They offer better insulation and soundproofing but are heavier, requiring sturdier frames and more installation time.
Emergency versus planned
Emergency jobs cost more than planned work. If you need a professional quickly, they must adjust their schedule, which translates into a higher price.
Weekend
Work at the weekend is more expensive than during the week. Professionals charge a surcharge for work outside regular hours.
Frame complexity
Special frame types or hard-to-reach windows require more time and expertise. More complexity means longer labour time and higher costs.
Surface area
The more square metres of HR++ glass you have installed, the higher the total costs, although the price per square metre may be slightly lower for larger projects.
Region
Prices are often higher in large cities due to higher labour costs and business expenses in urban environments.
Addressing small damage early
A small crack or broken sealant edge can still be repaired affordably. Waiting too long may result in having to replace the entire window.
Local professional
A local professional can be on-site faster and has lower travel costs.
Good preparation
Ensure the workspace is clear before the professional arrives. Moving furniture and removing obstacles saves labour time.

How does the professional work when installing HR++ glass?
- Measuring: The professional accurately measures the frame to determine the required glass sizes and checks the condition of the frame.
- Removing old glass: The existing glass is carefully removed, including old sealant and glazing beads.
- Preparing the frame: The frame is cleaned and checked for damage or rot.
- Installing new HR++ glass: The new glass is placed using special blocks for weight distribution and ventilation.
- Finishing: Glazing beads are replaced and edges are sealed with elastic sealant. Replacing a standard window takes about 30 to 60 minutes.
How can you save on installing HR++ glass?
- Check regularly: Inspect sealant edges and glass for cracks to prevent expensive replacements.
- Prepare the workspace: Make windows easily accessible by removing curtains and furniture to save labour costs.
- Plan smartly: Schedule the job during the week rather than as an emergency to avoid surcharges.
- Combine jobs: Have several windows replaced at once for a better price per square metre.
- Book via Zoofy: Get a fixed rate in advance, without call-out charges.
Common problems with glass and insulation
Condensation between the glass panes
This indicates a defective seal where the noble gas escapes. The glass loses its insulating effect and needs replacement.
Draughts around the windows
Outdated sealant edges or poorly insulated glass cause heat loss. Replacing this with HR++ glass improves comfort.
Cold radiation from windows
Old glazing radiates cold, which is uncomfortable. HR++ glass has a heat-reflective coating that reduces this effect.
