How to Purchase Curtain Wall for a Building?

1. Understand the Function of Curtain Walls

Before diving into the purchasing process, it’s important to understand what curtain walls are. Unlike load-bearing walls, curtain walls are designed to resist air and water infiltration, minimize sway, and improve energy efficiency. They are non-structural, meaning they only serve as an outer covering for the building, which means selecting the right curtain wall system is crucial for both appearance and functionality.

2. Determine Your Building’s Requirements

Every building has different requirements based on its design, location, and purpose. Some key factors to consider when selecting a curtain wall system include:

• Building Size and Design: Curtain walls must match the overall architectural style of the building. Skyscrapers or high-rise buildings might require stronger systems than smaller buildings.
• Weather Conditions: For regions with extreme weather (heat, cold, wind, or rain), choose curtain walls with high resistance to weather elements.
• Energy Efficiency: Modern curtain walls often come with insulation or energy-efficient glass, helping to reduce energy costs by maintaining internal temperatures.

3. Choose the Right Curtain Wall System

There are several types of curtain wall systems, each with different materials and installation methods. Some popular options include:

• Stick System: This is one of the most common types of curtain walls, where the system is assembled on-site, piece by piece. It offers flexibility but may require more time to install.
• Unitized System: The unitized curtain wall is pre-fabricated in sections and then assembled on-site. It’s faster to install than the stick system and generally results in better quality control due to the off-site assembly.
• Glazing Options: Choose between double-glazed or triple-glazed curtain walls, depending on your insulation needs.

4. Research Curtain Wall Manufacturers

Choosing the right curtain wall manufacturer is one of the most critical steps in the purchasing process. When evaluating manufacturers, consider the following:

• Reputation and Experience: Opt for manufacturers with a proven track record in producing high-quality curtain wall systems. Look for companies with experience in handling similar projects to ensure that they understand your specific requirements.
• Customization Options: Not all buildings are the same, so a good manufacturer should offer customization options for their curtain wall systems to fit the unique needs of your building.
• Certifications and Standards: Ensure that the manufacturer adheres to local and international standards and provides products that are certified for energy efficiency, wind resistance, and fire safety.
• Lead Times and Installation Support: Ask about the manufacturer’s lead time for delivery and whether they offer on-site installation support or training for your construction team.

5. Get Multiple Quotes and Compare

Before making a final decision, request quotes from several curtain wall manufacturers. A thorough comparison based on price, quality, warranty, and service will help you narrow down the best option. Remember that the cheapest option isn’t always the best—consider long-term benefits such as durability and energy savings when making your decision.

6. Inspect Samples and Review Past Projects

Request samples or visit projects where the manufacturer has supplied curtain walls to get a better sense of the product’s quality and appearance. If possible, ask for case studies or references to speak with other building owners or contractors who have worked with the manufacturer.

7. Finalize the Purchase Agreement

Once you’ve selected the manufacturer and system, it’s time to finalize the purchase agreement. Make sure the contract includes:

• Detailed specifications of the curtain wall system.
• Delivery timelines and any penalties for delays.
• Warranty details for both materials and installation.
• Maintenance and service agreements, if applicable.
