Step 1: Measuring the Aluminum Sliding Door and Construction Details 

One of the most critical steps before buying sliding doors is having accurate measurements and properly preparing the space where they will be installed. Mistakes at this stage can lead to extra costs, delays, last-minute adjustments, or even the need to replace the door. 

Rough Opening and Leveling 

It’s essential to verify that the rough opening has the correct dimensions and that the walls and floor are level and plumb. An irregular opening can affect sealing, panel movement, and the door’s energy efficiency. A professional can help ensure these measurements are accurate. 

Squareness and Alignment 

Check that the angles are exactly 90° and that there are no frame deformations. This will help prevent air and water infiltration, ensure the rollers function properly, and maintain correct lock alignment. 

Installation Tolerances 

Leave enough space for the frame, seals, and any necessary adjustments. Forcing the door into a tight opening can compromise performance and long-term durability. 

It’s also important to have technical drawings and measurements reviewed by a specialized installer to guarantee the door fits the space correctly and avoid future issues.

Step 2: Sliding Door Configuration and Usage 

Before choosing your sliding door, it’s important to define how it will be used and how many panels the space requires. An incorrect configuration can affect comfort, aesthetics, and functionality in the installation area. Some larger projects may even require more complex systems such as storefront systems and/or curtain walls. 

Number of Panels and Sliding Directions 

Sliding doors can be designed with 2, 3, or 4 panels, and the movement of each leaf should be selected according to the desired circulation and access. Some options combine fixed and operable panels, allowing for partial or full openings. 

Other alternatives, such as Max Slider systems, are ideal for maximizing visibility, though they’re not suitable for every project. 

Fixed vs. Active Panels 

A common mistake is failing to identify which panel will open and which will remain fixed. This affects the placement of the handle, the flow of entry and exit, and even the ventilation of the space. 

Interior and Exterior Space 

Evaluate the area surrounding the door: although sliding doors don’t take up as much space as hinged ones, you still need to ensure nothing blocks the movement of the panels and there’s enough clearance for comfortable passage. 

An architect can help you create a simple plan showing the opening direction of each panel to confirm that circulation will be practical and functional before manufacturing begins. 

Step 3: Sliding Door Performance and Comfort 

Choosing the right door is not only about size and design, it’s also important to evaluate thermal and acoustic performance, as these factors directly impact daily comfort and the space’s energy efficiency. 

Glass and Thermal Insulation 

Opt for high-performance glass, such as low-E with an air or argon gas chamber, which helps maintain a stable indoor temperature and reduces reliance on air conditioning or heating. Consider indicators like U-factor and SHGC to measure how efficiently the door limits heat transfer and solar radiation. 

Acoustic Insulation 

In urban areas or near noisy surroundings, selecting laminated glass with acoustic interlayers and well-sealed profiles can make a significant difference. This is essential if you want privacy and quiet inside the home or commercial space. 

Safety and Strength 

Ensure the door uses tempered or laminated glass to reduce breakage risks and features secure locking systems. 

💡 Tip: Not all standard doors meet advanced insulation requirements. If your project is in an extreme climate or noisy area, consider specialized configurations to achieve better comfort and efficiency. 

Step 4: Hardware and Safety First 

Hardware is a key component to ensure the proper operation and security of a sliding glass door. Choosing low-quality parts can lead to functional issues and compromise the system’s durability. 

Rollers and Tracks 

Look for high-capacity roller systems that can support the weight of the glass and guarantee smooth sliding. Tracks should be corrosion-resistant and well-sealed to prevent dust and water buildup. 

Some manufacturers, like PRL, offer top-rolling and bottom-rolling options, which help adapt to different project needs. 

Locks and Security Points 

Check that the door includes a reliable locking system, preferably with multi-point mechanisms, to strengthen security against intrusion attempts. 

Automation Compatibility 

If you plan to integrate automatic opening and closing systems, make sure the hardware and tracks are compatible with motors or smart accessories. 

Remember that investing in high-quality hardware from the start reduces the risk of costly maintenance and extends the overall lifespan of the structure.
