Comparison of sliding HS portal and classic balcony window in architecture

Choice for different types of clients

About the products

New technologies and design trends are constantly emerging in the architectural world, bringing innovation to the window and door industry. Two popular choices that are worth close examination are the sliding HS portal and the classic balcony window. These two options offer exceptional aesthetics and functionality, but each may be better suited to a certain type of client. In this article, we'll focus on comparing and assessing the pros and cons of both options and offer some tips to help architects and clients decide on the most appropriate solution for their projects.

Sliding HS portal:

The sliding HS portal is a modern, stylish and innovative design that is becoming an increasingly popular choice in architectural projects. It is a sliding door system that creates a transparent connection between the interior and exterior, allowing a seamless transition between the two spaces. Who is this option best suited for?

  • Modern minimalist clients:

Sliding HS portals are a popular choice for clients who prefer clean lines and minimalism in design. Thanks to their workmanship, they provide large glazed areas, allowing plenty of daylight to pass through and creating the impression of a more spacious area.

  • Spatial arrangement:

If there is limited space available to open conventional windows or doors, sliding HS portals are the ideal solution as they do not need any space to open in or out. Hand in hand with the sliding system goes the possibility of large glazing where we are much less limited than with conventional balcony windows.

  • An effort to connect the interior with the exterior:

For those who wish to connect their homes to the outdoors, sliding HS portals are a great option as they create an efficient and aesthetic connection between the two areas.

Classic balcony window:

The classic balcony window is a long-standing favourite and its tradition goes back to the history of architecture. This window is openable, consists of one or more sashes and provides users with efficient ventilation and plenty of daylight. For whom is this option best suited?

  • Clients with traditional tastes:

For those who prefer a traditional, elegant and rustic look, classic balcony windows are the ideal choice. These windows bring classic character and can be the perfect addition to historic or traditional homes.

  • Spatial arrangement:

Classic balcony windows, unlike HS portals, do not require a large construction opening. If we imagine an HS portal in a building opening of 2 metres, when opened it will create a maximum 800mm transition to the exterior. For example, if we use a double leaf balcony without a central pillar, there will be a transition of more than 1.7 metres when both wings are open. However, it should be borne in mind that the open sashes encroach into the space.

  • Financial considerations:

If clients are looking for a more economical option, traditional balcony windows may be a more affordable alternative than modern sliding HS portals.

The choice between a sliding HS portal and a conventional balcony window depends on individual preferences, needs and project characteristics. Sliding HS portals are ideal for clients looking for a modern, minimalist design and a connection between the interior and exterior. On the other hand, classic balcony windows are more suitable for those who prefer a traditional and elegant look, and also for those looking for a more economical option.

In any case, it is important to work with a qualified architect who can help you select the most appropriate window solution for your specific project, ensuring optimal functionality and aesthetics for your home or commercial building.
