What are framed terrace glazing panels?
Framed terrace glazing panels are aluminium-framed sliding panels that move along upper and lower tracks. This is the most common and typical terrace glazing solution — reliable, durable, and suitable for almost any structure. Each glass panel is surrounded by an aluminium frame that gives the system rigidity and protects the glass edges.
Framed sliding glass panels are a particularly popular choice for glazing existing terraces where the structure is already in place and the goal is to add weather protection without major reconstruction. In Pärnu and Pärnumaa, where the maritime climate places higher demands on materials, aluminium-framed systems have proven themselves especially well — the frame protects the glass and tracks even in stronger winds.
Advantages of framed terrace glazing
The framed sliding system is the preferred choice of many homeowners, and there are several good reasons for this:
- Durability and long service life. The aluminium frame protects the glass edges and tracks from mechanical damage. The frame adds rigidity to the entire system, meaning less wear and a longer lifespan even with intensive use.
- More lenient tolerance requirements. The structural tolerance of framed sliding systems is ±7 mm — significantly more lenient than the ±2 mm of frameless folding glass. In practice, this means a framed system works without issues even on structures that were not built to millimetre precision.
- Compatible with a wide range of structures. Existing terraces, older wooden houses, concrete structures — the framed system is flexible and adaptable. If your terrace already exists, framed sliding glass panels are often the simplest and most reliable choice.
- Good wind resistance. The aluminium frame gives each panel additional rigidity, which is particularly important in Pärnu’s coastal location where wind loads are considerable. Thicker glass combined with a strong frame handles even stronger storms without issue.
- Easy maintenance. Framed panels are easy to remove and reinstall, making both cleaning and repairs convenient when needed. Aluminium profiles do not rust and require no painting.
- Reasonable cost. Framed sliding glass panels are the most affordable of the three main systems, making quality terrace glazing accessible to a wider range of customers.
How do framed sliding glass panels work?
The framed sliding system consists of aluminium-framed glass panels that glide along upper and lower tracks. Each panel moves independently — you can open exactly as much as you want and from exactly where you need.
The system works as follows:
- Tracks. The upper and lower aluminium tracks are fixed to the terrace structure. The tracks contain runners along which the panels move.
- Sliding panels. Each glass panel sits in an aluminium frame and glides smoothly back and forth along the rail. Panels can be pushed behind one another to partially or fully open the terrace.
- Locking. Panels are locked in the closed position with a safety lock that protects against both wind and unauthorised entry. The locking system is integrated into the frame, so no additional hardware is needed.
- Seals. There are seals between the panels and along the track edges that protect against rain and draughts. The seals ensure that a closed terrace is truly weatherproof.
The entire system is designed so that it can be operated with one hand — the panels move smoothly and lock securely. Everyday use is simple and comfortable.
Glass options
Framed terrace glazing uses tempered safety glass — this is a mandatory safety requirement that ensures that in the event of breakage, small fragments are produced without sharp edges.
Glass options:
- Glass thickness: 6–10 mm. The choice of thickness depends on the panel size and wind load. In coastal Pärnu the wind load is greater than inland, which is why we often recommend thicker panels. Thicker glass is also better at sound insulation and more durable.
- Clear glass. Standard transparent tempered glass that lets through the maximum amount of light and preserves a panoramic view.
- Tinted glass. Grey, brown, or green tint reduces solar radiation and heat, which is especially useful on south- and west-facing terraces. Tinted glass also provides privacy.
We always provide our glass thickness and type recommendation based on the specific project — taking into account the terrace location, compass orientation, wind load, and panel dimensions.
Malmerk Klaasium framed systems
ATKA Klaaskoda installs Malmerk Klaasium framed terrace glazing — a product from Estonia’s largest glass manufacturer, designed and produced for the Nordic climate.
Advantages of Malmerk Klaasium systems:
- CE marking and VTT certificate. The products meet European safety requirements and have undergone independent testing by the Finnish VTT institute. This is a quality guarantee that imported solutions often cannot provide.
- Wide RAL colour selection. Aluminium profiles and frames are available in many RAL colour shades — white, anthracite grey, black, brown, and many others. The profile colour can be matched to your home’s facade, windows, and terrace style.
- Nordic climate resistance. The systems have been tested and proven in Finnish, Swedish, and Norwegian climates — winters that are even more severe than Estonia’s. Pärnu’s maritime climate, salty air, and temperature fluctuations are no problem for Malmerk systems.
- Spare parts availability. Since Malmerk is an Estonian manufacturer, spare parts and accessories are quickly available. With imported solutions, waiting for a spare part can take weeks.
Who are framed terrace glazing panels suitable for?
Framed sliding glass panels are the best choice in the following situations:
- An existing terrace. If your terrace is already built and you want to add glazing, a framed system is usually the most suitable choice. The ±7 mm tolerance means the system works even on structures that were not originally designed for glazing.
- Older structures. Wooden houses, older concrete terraces, and other structures where absolute stability cannot be guaranteed — a framed system tolerates minor movement better than frameless solutions.
- Practicality first. If you prefer a reliable and simple solution that requires minimal maintenance and works comfortably on a daily basis — framed sliding glass is the right choice.
- Coastal location. On the Pärnu coast and on the islands, where wind loads and salty air are everyday factors, the aluminium frame gives the glass panels additional rigidity and protection.
If you are not sure which system suits your terrace, don’t worry — we will help you choose. Our team carries out a free on-site measurement and provides a recommendation based specifically on your project. Also see frameless terrace glazing if you prefer a more modern and minimalist solution.
Framed vs frameless — a brief comparison
Both framed and frameless terrace glazing are quality solutions, but they suit different situations:
- Tolerance: framed ±7 mm vs frameless folding ±2 mm. For an existing terrace, a framed system is the safer choice.
- Aesthetics: the framed system has a visually visible aluminium frame, whereas the frameless solution is more minimalist and modern.
- Price: the framed system is the most affordable, frameless sliding is slightly more expensive, and frameless folding is the most expensive.
- Opening: framed sliding glass panels open partially (panels slide behind one another), while frameless folding panels open fully.

Full-service solution — from foundation to glass
Unlike many glass companies that only handle installation, ATKA Klaaskoda offers a full-service solution: foundation, load-bearing structure, glass, and warranty — all from one place. 30+ years of construction experience in Pärnumaa means we know the local building conditions — sandy soil, high groundwater, coastal winds, and the structures of old wooden houses.
One contract, one team, one warranty. This ensures that the structure and glazing system work together even years later. The framed system’s ±7 mm tolerance is lenient, but even that requires a proper foundation — and we build it ourselves.
Frequently asked questions
What is the difference between framed and frameless terrace glazing?
In framed terrace glazing, each glass panel is enclosed in an aluminium frame that gives the system rigidity and durability. Frameless systems have only glass in the tracks without a surrounding frame — more aesthetically pleasing, but more demanding on the structure. The tolerance of a framed system is ±7 mm, while for a frameless folding system it is only ±2 mm.
Are framed terrace glazing panels suitable for an existing terrace?
Yes, framed sliding glass panels are an especially good choice for glazing existing terraces. The ±7 mm tolerance means the system can handle minor movement in the structure, which is common with older terraces. We always carry out a free on-site measurement first to confirm suitability.
How much do framed terrace glazing panels open?
Framed sliding panels move behind one another, opening the terrace partially. Typically around 75% of the total glass surface can be opened. If you want to open the terrace fully, a frameless folding solution is a better fit.
How do you maintain framed terrace glazing?
Maintenance is simple: clean the glass with a standard glass cleaner 2–4 times a year. Clean the tracks and rails of dirt and sand — especially after winter. Check the seals once a year. Aluminium frames require no painting or special treatment. In a coastal location we recommend cleaning more frequently, as salty air leaves deposits.
Do framed terrace glazing panels protect against wind and rain?
Yes. In the closed and locked position, framed sliding glass panels effectively protect against wind, rain, dust, and noise. The seals between panels and the design of the tracks ensure the terrace is weatherproof. In the coastal areas of Pärnu, where strong westerly winds are common, the framed system has proven itself particularly well thanks to the additional rigidity provided by the aluminium frame.
