An integral part of the facade of modern high-rises, curtain wall systems actually come in a wide variety of configurations. Builders and contractors can choose from stick, point-fixed, semi-unitized, and unitized curtain wall systems to achieve their building’s performance and architectural goals.
Speaking of performance, a lot of contemporary towers are designed with the intent of combining solid wall areas with glazed openings to meet their ventilation and energy requirements. This alters the specific considerations for the interior and exterior-facing parts of the facade system.
Here is where hot-cold curtain wall systems can help. Designed to accommodate window openings into solid walls, it divides the facade into two distinct zones: a warm zone and a cold zone.
Contractors and builders planning to incorporate this system into their construction project must familiarize themselves with its basics to get it right. In today’s blog, HaloGlass, suppliers of top-notch aluminum facade systems in Ontario, will explain how hot-cold facade systems work. Let’s begin!
What Is A Hot-Cold Curtain Wall System?
A hot-cold curtain wall system is defined by its separate facade zones. The warm zone of the system refers to the thermally enclosed portion of the building, while the cold zone is part of its exterior-facing area.
It does not take a uniform approach to facade assembly. Instead, it accommodates both temperature conditions into a single coordinated solution that makes it the perfect choice for projects where conventional full-height systems do not work.
Where Do The Warm & Cold Zones Fit In This Facade System?
The different sections of a building’s envelope and their respective construction and performance requirements ultimately decide the location of both warm and cold zones.
Only the most appropriate combination of profiles and components that serve the purpose of each section should be used. For example, cold zones can be lined up with solid masonry walls or concrete floor slabs, while warm zones are meant to be positioned right in front of a building’s window openings. This not only optimizes the energy usage of a building, but also serves as a cost-efficient facade system for large-scale projects.
How To Integrate Windows & Doors Into Hot-Cold Curtain Wall Systems?
Incorporating windows and doors into this type of curtain wall system is actually very easy. Hot-cold curtain walls are designed to maintain a connected and cohesive experience while accommodating doors and windows of consistent sizes.
In fact, contractors get the flexibility to plan windows and doors into the facade’s components as interconnected elements of the building’s envelope rather than having to specify them individually.
Installation Considerations for Hot-Cold Curtain Wall Systems
Efficiency is the name of the game with hot-cold curtain wall systems. They are designed to support quick and easy installation.
However, early coordination remains important in ensuring only correctly specified components arrive on site. Contractors must consider the following factors to achieve the perfect fit and finish:
- Verify facade layouts and zone locations
- Coordinate window and door openings
- Evaluate substrate and structural conditions
- Determine how to connect cold and warm areas
- Coordinate all other facade components before installation begins
As for the design and finish of the system, contractors can order them in different colors and profiles. Options include powder coating, anodized finishes, and wood grain effect, along with a wide selection of standard colors and surface treatments that help create a more coordinated facade system.
Conclusion
Hot-cold curtain wall systems take a unique approach to facade construction. Their distinct combination of solid wall areas and glazed openings allows the installation of compatible windows and doors within the facade itself, allowing contractors to meet the requirements of complex facade projects.
Of course, customization is necessary to ensure they truly fit into a project’s architectural vision. HaloGlass offers tailored aluminum facade systems in Ontario that are perfect for both commercial and residential high-rises. Contact us to discuss the specifications of your next development.
