Why Alu180 for this project? The 3.5m width fits perfectly within the Alu180's 5m max span capability. The 2.0mm thick posts provide excellent structural stability, while the 180mm wide louvers offer optimal coverage with minimal visible seams. For spans over 5m, we recommend upgrading to the Alu220 heavy-duty series.
3. 5% Light Gray Windproof Roller Blinds
The windproof zipper roller blinds (also called zip-screen blinds) are installed on all four sides of the pergola, providing complete enclosure when needed. The light gray 5% openness PVC mesh fabric was selected for its balance of shade, visibility, and airflow.
| Feature | Specification |
|---|---|
| System Type | Zip-Track (Zipper) Roller Blind |
| Fabric Color | Light Gray |
| Openness Factor | 5% |
| Material | PVC Coated Polyester Mesh |
| UV Blocking | Up to 95% |
| Wind Resistance | Up to 120 km/h |
| Max Width | 6.0m |
| Max Height | 4.0m |
| Operation | Motorized, Remote + APP |
| Sides Covered | 4 (Full Enclosure) |
Understanding 5% Openness
The "5% openness" refers to the density of the mesh weave. A 5% fabric has approximately 5% open area, meaning:
- ✅ Blocks 95% of UV rays and reduces heat by up to 40%
- ✅ Allows natural airflow — prevents the space from feeling stuffy
- ✅ Maintains outward visibility during the day (you can see out, but outsiders can't see in)
- ✅ Provides a soft, diffused light rather than complete darkness
- ✅ Water-resistant — sheds light rain, dries quickly
For comparison, a 1% fabric offers near-blackout privacy, while a 10% fabric is more transparent. The 5% option is the most popular choice for patio and pergola applications.
4. Step-by-Step Installation Process
Day 1: Frame Assembly & Roof Installation
- Site Preparation (1 hour): Level the patio floor, mark anchor points for the 4 posts using the provided installation drawing. Clean the area of debris.
- Post Installation (2 hours): Fix the 135×135mm posts to the concrete floor using M12 chemical anchors. Verify vertical alignment with a spirit level on both axes.
- Beam Assembly (2 hours): Connect the 165×110mm front and rear beams to the posts using stainless steel brackets. Install the intermediate support beam at the 5m midpoint.
- Louver Blade Installation (3 hours): Mount the 180mm louver blades onto the rotation linkage. Connect the tubular motor and test blade rotation (0° to 120°).
- Gutter & Drainage (1 hour): Install integrated gutter system inside the beams. Connect downspouts to the posts and verify water flow.
- Wiring & Control Box (1 hour): Run power cable to the control box. Pair the remote control and test all motor functions.
Day 2: Roller Blinds & Final Commissioning
- Track Installation (2 hours): Mount zip-track side guides on all four sides. Ensure tracks are perfectly vertical and parallel.
- Roller Tube & Motor (1.5 hours): Install motorized roller tubes with the light gray 5% fabric pre-rolled. Set upper and lower limits.
- Fabric Threading (2 hours): Thread the fabric edges into the zipper tracks. This is the most delicate step — the fabric must be evenly tensioned to prevent jamming.
- Bottom Bar & Handles (1 hour): Attach the aluminum bottom bar. Install optional pull handles for manual override.
- Smart Control Setup (1 hour): Connect to WiFi, configure Tuya Smart APP. Set up voice control (Alexa/Google Home) if requested.
- Final Testing & Adjustment (1 hour): Run full cycle tests on all motors. Adjust blade angles, blind tension, and sensor sensitivity.
- Cleanup & Handover (1 hour): Clean the site, remove packaging. Demonstrate operation to the client and provide the user manual.
💡 Pro Installation Tips
- Always use chemical anchors (not expansion bolts) for concrete floors — they provide 3x the holding power
- Leave a 50mm gap between the post base and the floor for water drainage and corrosion prevention
- Apply silicone sealant at all beam-to-post connections after assembly to prevent water ingress
- Test the rain sensor by spraying water — the louvers should automatically close within 30 seconds
- For the 5m length, add a center support post or use the Alu220 series if snow load is a concern

6. Key Benefits & Performance
☀️ All-Weather Versatility
Motorized louvers adjust from fully open (90% sunlight) to fully closed (100% waterproof). The 5% blinds add side protection from sun, wind, and insects. Use the space in any weather.
💨 High Wind Resistance
Aluminum frame withstands Grade 8 winds. Zip-track blinds stay taut up to 120 km/h. Ideal for coastal areas and windy climates — no need to retract in moderate wind.
🔋 Smart Control
Operate via remote, WiFi APP, or voice (Alexa/Google). Built-in rain and wind sensors automatically close the louvers and retract blinds when bad weather hits.
🛡️ Low Maintenance
Powder-coated aluminum resists corrosion, fading, and scratches. Annual hose-down is all that's needed. No fabric to replace on the roof — only the side blinds (10+ year lifespan).
🌡️ Energy Efficient
Reduces patio temperature by up to 8°C in direct sun. Blocks 95% of UV rays, protecting furniture and flooring. Lower AC bills for adjacent indoor spaces.
🎨 Customizable Design
Any RAL frame color, multiple fabric colors and openness levels (1%, 3%, 5%, 10%). Optional LED lighting, glass doors, curtains, and heating elements to match any style.
Client Feedback
"The gray pergola completely transformed our backyard. We use it every evening — the 5% blinds are perfect because they keep the area cool but we can still see the garden. Installation was quick and the team explained everything clearly. Best home improvement decision we've made!"

7. Frequently Asked Questions
What is the Alu180 series pergola?
The Alu180 series is AluShed's standard motorized louvered pergola line with Post 135×135×2.0mm, Beam 165×110×1.6mm, and Blade 180×35×1.5mm. It is suitable for spans up to 4-5m and is the most popular choice for residential patios and small commercial spaces.
What does 5% openness mean for roller blind fabric?
5% openness means the fabric allows approximately 5% of light to pass through while blocking 95% of UV rays. This provides excellent shade and heat reduction while maintaining outward visibility and natural airflow. It is ideal for areas where you want shade without feeling enclosed.
How long does it take to install a 3.5×5m pergola with blinds?
A typical 3.5×5m Alu180 pergola with four-sided windproof roller blinds takes 2 professional installers approximately 2 days. Day 1 covers frame assembly and roof installation; Day 2 covers roller blinds, wiring, testing, and final adjustments.
Can the gray frame color be customized?
Yes. AluShed offers any RAL color powder coating, including the popular gray RAL 7016 used in this project. Other common options include black (RAL 9005), white (RAL 9016), anthracite gray (RAL 7016), and wood grain finishes. Custom colors typically add 5-7 days to production.
What is the wind resistance of this configuration?
The Alu180 pergola frame withstands wind up to Grade 8 (62-74 km/h) with louvers closed. The zip-track windproof roller blinds are rated up to 120 km/h when fully deployed. For high-wind areas, we recommend retracting the blinds during storms and keeping louvers at 45°.
