Replacing a garage door in an older building or installing a modern system in an underground garage often involves significant structural challenges. Lack of an appropriate lintel, strict building regulations, and maintaining optimal humidity levels are everyday concerns for investors.
The answer to these challenges is a new addition to the KRISPOL offering (available from July 22, 2026) – a perforated ventilation fascia designed for sectional doors.
In this article, you will learn how to use it correctly and how to effectively carry out a garage renovation.
What is a ventilation panel and when should it be used?
A perforated ventilation panel is a technically advanced steel solution designed for K2 R sectional garage doors. The design has been optimised for two common track systems: N (required lintel height 210 mm) and L (required lintel height 120 mm).
The new panel serves exclusively a ventilation function and is not a structural or load-bearing element of the door. Thanks to precise perforation, it ensures continuous air circulation inside the space without the need to unseal the door itself or install unaesthetic ventilation grilles in the door panels.
Important design note: Since the fascia is installed within the clear opening, the ordered height of the sectional garage door must always be reduced accordingly and precisely adjusted to the clear opening height that will remain after installation of the ventilation element.
Renovation solutions: How to handle challenging building conditions?
In older single-family housing, garages were often designed without taking modern installation standards into account. As a result, investors frequently face issues such as a complete lack of a lintel or very low ceiling height. A similar challenge occurs in multi-space underground garages.
The introduction of the perforated ventilation fascia fits perfectly into the comprehensive renovation strategy of KRISPOL. The new fascia effectively conceals architectural imperfections and enables a clean, non-invasive installation of a sectional door—also in locations where this was previously impossible due to technical or formal constraints.
Why is continuous garage ventilation essential? Health and vehicle protection
Using a garage without proper air exchange can lead to serious consequences. A ventilation panel performs exceptionally well in everyday use, especially during autumn, winter, and spring, when vehicles enter the garage wet, covered with snow, mud, or rain. It is particularly suitable for garages that are not integrated into the building structure.
By ensuring continuous air circulation, the panel provides a range of tangible benefits:
- Elimination of moisture and mould: Prevents condensation on walls and ceilings, protecting the building structure from the destructive effects of fungi.
- Anti-corrosion protection for vehicles: Accelerates the drying of cars, motorcycles, and bicycles, minimizing the risk of corrosion.
- Improved user health: Prevents inhalation of mould spores and supports the removal of harmful exhaust fumes and chemical vapours.
Technical specification and installation guidelines
To facilitate the correct selection of the solution for a specific renovation project or a newly constructed building, the key technical parameters of the new KRISPOL ventilation panel are listed below.
| Technical parameter | Specification and execution guidelines |
| Dedicated system | KRISPOL K2 R sectional garage doors |
| Compatible track systems | Track type N (lintel height 210 mm) and L (lintel height 120 mm) |
| Available standard lengths | 2500 mm and 4000 mm (width adjusted to fit the opening) |
| Material and finish | High-quality galvanized steel or coated in any colour from the full RAL and NCS palette |
| Content of the installation kit | Dedicated mounting brackets and system rivets |
| Requirement for track type N | Option with central support: installation of the central support to the ceiling is required by rotating it by 90° (while maintaining the minimum required lintel height). |
Comprehensive renovation solutions from KRISPOL
In older garages, ideal lintel heights or properly formed side reveals are rarely found. How does KRISPOL technology address this? The answer is simple: thanks to dedicated KRISPOL renovation solutions, the architectural limitations of existing buildings are no longer an obstacle.
-
Renovation frames
Our PA100R and PA120R renovation frames are the ideal solution for quick and easy installation of a sectional garage door when side reveals and the lintel are missing.
Advantages:
- Perfect fit to the façade
- Wide range of colours – RAL, NCS, foil finishes
- Thermal and acoustic insulation
- Made of steel
- Flexibility of solutions – possibility to order a reduced number of profiles (e.g. when only the side reveals are missing)
-
Vertical angle cover
Enjoy a new sectional garage door even if you have limited side reveal width or insufficient lintel height. The cover is designed for sectional garage doors with standard installation, i.e. mounted behind the opening. Its modern, minimalist design allows it to blend seamlessly with any building.
Advantages:
- Can be used in buildings where the minimum side reveal width is not met – installation with the cover is possible from a reveal width of just 60 mm
- Can be used in buildings where the minimum lintel height is not maintained – maximum possible reduction of 50 mm
- Intuitive installation system
- Easy alignment with the aluminium lintel trim
- Wide range of colours – RAL, NCS, foil finishes
- Durable construction ensuring long service life
-
Lintel strip
The aluminium lintel trim is used when building conditions do not allow the garage opening to be completely closed. It enables the installation of a sectional garage door of standard height in a higher clear opening. This is an excellent solution that allows the installed sectional garage door to be perfectly matched to an existing opening.
Advantages:
- Possibility to close the remaining clear opening by up to 50 mm
- Suitable for all types of garage track systems (except track type H)
- Wide range of colours – RAL, NCS, foil finishes
- Made of aluminium
Summary: A garage without technical limitations and moisture
Modernising a demanding garage—whether in an older single-family house or in a tight underground parking facility—does not have to mean costly masonry work or compromises. The new perforated KRISPOL ventilation fascia (available from July 22, 2026), combined with system renovation solutions such as PA100R/PA120R frames, vertical angle covers and lintel trims, enables non-invasive and aesthetically pleasing installation of a sectional door in almost any conditions.
By using these solutions, you gain not only a perfect fit to the façade and effective masking of wall irregularities, but above all continuous air circulation. This is the key to a healthy microclimate that effectively protects your vehicle against corrosion and the building structure against moisture and mould.

Frequently Asked Questions (FAQ)
-
Can the ventilation fascia replace a missing structural lintel?
No. The fascia serves exclusively as a ventilation element and is not a load-bearing or structural component of the door. Its purpose is to ensure air circulation and to aesthetically cover the free space. Please note that the ordered height of the door must be reduced accordingly by the height of the installed fascia.
-
What sizes and colour options are available?
The KRISPOL ventilation fascia is available in two standard lengths: 2500 mm and 4000 mm (the width is ultimately cut and adjusted to fit the garage opening). In terms of aesthetics, there are no compromises – the element can be supplied in a galvanized finish or coated in any colour from the full RAL and NCS palette, ensuring a perfect match with the door leaf.
-
What is included in the ventilation fascia installation kit?
By choosing this solution, you receive a complete system ready for installation. The set includes dedicated mounting brackets and system rivets, ensuring quick, secure, and aesthetically pleasing installation.
-
I have a low lintel and track type N – can I install the fascia?
Yes, but specific technical requirements must be met. For track type N (required lintel height 210 mm), installation of the fascia requires the option with a central support. The support must be mounted to the ceiling by rotating it by 90°, while maintaining the minimum lintel height specified in the installation guidelines.
