Curtain-walls

Curtain walls are made of metal poles called mullions, which make up the framing of the walls or panels. It is an external, non-bearing wall that is hung off concrete slabs via anchors.Unlike punched windows, these cover the entire exterior of the building it is installed on, which makes it suitable for commercial use.
This glazing system is designed to attach to the façade of a building on the slabs, thus acting as a ‘curtain’ that hangs from the structure. Each unit is sent to the field, ready to be anchored and boasts superior structural strength. Due to its robustness, curtain walls provide excellent protection against harsh elements, such as high wind loads, earthquakes, and can handle larger glass sizes compared to window walls.
At NORTEM, each panel that makes up a curtain wall is inspected for consistent quality control before it is dispatched. This is why our curtain walls are highly durable and do not require a lot of maintenance to remain pristine and functional.
This glazing system is installed using cranes or rigs since it has to cover the façade of the building. The entire process is complex and is more expensive compared to other glazing systems.

Curtain-wall Systems

A curtain wall is a glazed wall system hung off a concrete slab using anchors. Curtain walls are self-supporting and give a building’s exterior the look of top to bottom glass.

Most often used on commercial buildings, curtain walls are typically installed from the outside of a building using cranes or rigs. Curtain wall installation is a complex process and can be more expensive than other systems

Curtain Wall Advantages

If installed correctly, curtain wall systems provide excellent structural integrity, as there are fewer mullions and joints required when compared to most window wall systems.

Acting as a single unit, curtain walls are highly resistant to moisture, wind, heat and earthquakes. They require little maintenance.

Window Walls

Unlike curtain walls, window walls are installed between floor slabs. Each unit is anchored at the head and the sill before it is sealed using caulking.
These are popular as residential applications since these can be customized and installed from the inside as well. This makes window walls more cost- efficient and safer compared to curtain walls.
Since window walls are installed between floor slabs, fire stopping is unnecessary. This also allows this glazing option to dampen noise, which curtain walls may not be capable of doing.
However, unlike curtain walls, window walls do not have the structural integrity and strength that it can be installed on tall buildings without compromising safety.
Even though window walls are less expensive than curtain walls, the high number of caulk joints it has requires regular maintenance, which can lead to more expenses.
In other words, before choosing either of the glazing systems, consider the aforementioned variables to make an informed decision. Our experienced team has experience installing and maintaining both solutions and can help you determine the best option.

Window-wall Systems

A window wall is achieved by placing glazing between a building’s concrete slabs, using the slabs as structural support.Window walls have a break between the glass, with slab covers used to conceal the concrete.

Window walls are often used in residential applications as they allow for more customizable sections such as windows and balcony doors. They are most commonly installed from the inside of a building, which is a safer, more efficient and more cost effective.

Window Wall Advantages

Aside from advantages such as customization, ease of installation and cost savings, window walls also require less engineering and safety considerations as the exterior wall is broken up by each floors’ concrete slab, providing built-in fire stopping.

Also, because the separation of each window wall unit creates a sealed space there is less noise transfer and energy loss. Further, if a unit becomes damaged and needs repair that specific unit can be removed and replaced without affecting the adjoining units.
