Types of Curtain Wall Systems: Which One is Better?

There are several types of curtain wall systems commonly used in construction, each with its own advantages and considerations. The choice of the best curtain wall system depends on various factors such as project requirements, architectural design, budget, environmental conditions, and aesthetic preferences. Here are some common types of curtain wall systems and their characteristics:

Stick-Built Curtain Wall System:

In a stick-built curtain wall system, individual components such as aluminum or steel mullions, transoms, and glass panels are assembled on-site.

This system offers flexibility in design and can accommodate complex building shapes and angles.

Installation can be time-consuming and labor-intensive, but it allows for easier replacement of damaged components.

Unitized Curtain Wall System:

Unitized curtain wall systems consist of pre-assembled units or panels that are manufactured off-site and transported to the construction site for installation.

This system reduces on-site labor and installation time, resulting in faster project completion.

Unitized systems offer better quality control and weatherproofing, as units are fabricated in controlled factory conditions.

Spider Glass Curtain Wall System:

Spider glass curtain walls use point-supported glass panels attached to a structural frame with spider fittings or tension rods.

This system provides a transparent and minimalist aesthetic, allowing for uninterrupted views and abundant natural light.

Spider glass curtain walls are suitable for modern and high-end architectural designs but may require careful engineering to ensure structural integrity.

Double Skin Curtain Wall System:

Double skin curtain walls consist of two layers of glass separated by an air cavity or space, providing enhanced thermal insulation and acoustic performance.

This system offers energy efficiency benefits and can help reduce heating and cooling costs in buildings.

Double skin curtain walls require careful design and consideration of ventilation and condensation management.

Point-Supported Glass Curtain Wall System:

Point-supported glass curtain walls use glass panels suspended from structural support points, typically with stainless steel fittings or cables.

This system offers a sleek and modern aesthetic with minimal structural framing visible.

Point-supported glass curtain walls are suitable for applications where transparency, openness, and architectural elegance are desired.

Aluminum Composite Panel (ACP) Curtain Wall System:

ACP curtain wall systems use lightweight aluminum composite panels as cladding material attached to an aluminum or steel frame.

This system offers design versatility, color options, and ease of installation.

ACP curtain walls are suitable for both new construction and renovation projects, providing a cost-effective solution with good weather resistance.

There is no one-size-fits-all answer to which curtain wall system is better, as each has its own advantages and considerations depending on the specific project requirements and constraints. It's essential to work closely with architects, engineers, and curtain wall specialists to evaluate the options and choose the most suitable system for your project. Factors such as performance, aesthetics, cost, maintenance requirements, and local building codes should all be taken into account when making this decision.
