7 frequently asked questions about large windows

Large-size glazing, especially in the living room, has recently become extremely fashionable. What do they owe their popularity to? They allow you to achieve a spectacular effect, decorate the interior and the volume of the building itself, conveniently connect the home zone with the garden. But what about the practical aspects? Are such windows tight, safe, expensive? We answer the most frequently asked questions.

Are we exposed to drafts when choosing the HST system?

The HST design has become very popular in Poland. This is a solution taken from the markets of southern Europe, where we definitely observe a different climate. As a result, the parameter of air tightness in terrace doors is slightly different from traditional window systems, but still qualifies for the highest, 4th class. All thanks to a well-thought-out system of pressure seals. In the HST construction, we use a parallel, adjacent sealing system - perfectly fulfilling its functions.
It is worth remembering that in the case of joinery, a properly performed assembly plays a huge role, well-installed terrace doors in the HST system should not cause noticeable drafts in the house.

Do I have to choose aluminum windows for glass facades?

Facades, or "glass walls", are designed to let as much light into the interior as possible. Often, impressive dimensions or non-standard dimensions also affect the visual aspect. In practice, it is also the size of the planned glass pane that determines the choice of material from which the product will be made. In the case of HST structures - the maximum size is 14 m ² , if the investor assumes a single pane of glass that will not open - 7 m ² . However, in the case of entrance doors, aluminum systems are dedicated, regardless of their dimensions.

However, we always remind investors that by choosing KRISPOL aluminum windows for large glazing, they can successfully mix solutions and, for example, use PVC for windows with smaller areas.

In order to have a threshold-free passage in the case of the HST system, do I need to buy a special threshold?

Having the KRISPOL FEN 82 HST structure, at any stage the investor can equip the sliding window with a flat threshold with a hidden rainwater drain. Throughout the entire depth of the threshold installation - nearly 200 mm - the only visible element of the structure in the clear passage is a low, 5 mm running rail.

As a standard, HS thresholds, after complete installation, have a threshold height of about 30 mm - this is a visible, natural slope for water drainage.

Are large windows expensive?

It is worth remembering that the size of the window affects its price, but it is not the only factor that matters:

• Opening type - by far the most economical solution is to use a FIX window, i.e. a fixed, non-opening structure. Among the openable systems, the PSK tilt and slide system will be cheaper, and the HST sliding system will be the most expensive.
• Window material - PVC (more economical version), aluminum.
• Choice of veneer - from one of two price groups.
• Bicolor - a window veneered or painted (in the case of aluminum windows) from the outside and inside.
• Accessories - i.e. the choice of a warm frame, a warm window assembly system, etc.

If we were to compare an opaque wall with a glazed one, it is indeed a more expensive solution. It is worth remembering, however, that it is not without reason that there is a trend for large-size glazing, and staying in an interior that receives natural light means better comfort and well-being of residents. In addition, convenient covers such as facade blinds allow you to freely control the amount of light.

If we want to optimize the price - we recommend fixed FIX windows, they are also great for investments with mechanical ventilation with heat recovery.

Are large windows difficult to clean?

Large glazing can actually be a hassle to clean. It is always worth considering practical issues at the house design stage - the entire wall in the form of a glass facade will create an amazing effect, but at the same time it may generate the need to hire external companies to help or use a washer on a long telescope.
The lower windows can be successfully cleaned by yourself, and the operation is the same as in the case of all other windows. So why is this question so often asked? Let us remember that having a terrace window and children at home, or quadrupeds - we naturally have to wash such a window more often. In this case, investors often use two solutions that facilitate cleaning:

• The use of Bioclean self-cleaning glass, which prevents water from settling during rainfall, thanks to which the glass remains clean for longer. However, it still needs to be washed, but much less frequently.
• Robots for cleaning windows - there are more and more products on the market that relieve us of this task.

Large window - does it affect security?

When choosing large-size glazing, we should not worry about safety aspects. Each window size has specially selected components, which are selected on the basis of numerous safety tests. However, it is worth reckoning with the fact that the size of the window may require the use of fittings with a higher load capacity or safe, tempered or laminated glass. In addition, at the product selection stage, you can opt for reed switches built into the product, enabling connection to any alarm system.

Large windows - what to pay attention to and what an investor can forget about?

In the case of large windows, as in the case of all others, it is worth considering what the needs of future residents are, who will use the products, what are our visual preferences, what thermal parameters should these products have.

In the case of glass facades, you should also remember about thermal comfort inside the room and the aspect of ensuring privacy. In both cases, facade blinds will be perfect.
