The comfort and energy efficiency of a modern building come from everyday actions like opening and closing openings. However, when it comes to out-of-reach windows, roof skylights, or large industrial domes, manual operation is no longer practical. This is where automation comes in.

In this comprehensive guide by VDS Automazioni, we’ll explore everything you need to know about choosing and installing motors for openings, analyzing the best solutions for every type of window and providing technical tips for seamless integration.

Why Automate? Not Just Convenience, But a Strategic Choice

Automating a skylight or window isn’t just about convenience. It’s a strategic choice that impacts:

1. Air Quality: Promoting natural air circulation reduces CO2 and indoor pollutants.
2. Energy Efficiency: Integration with climate sensors allows closing openings in case of rain or opening them for passive nighttime cooling.
3. Safety and Accessibility: Making light and air points accessible that would otherwise be unusable, especially for people with reduced mobility.

Which System to Choose? A Solution for Every Opening

Not all motors are the same. The choice of actuator depends on the mechanics of the opening, its weight, and available space.

Automation for Windows (Tilt, Projecting, Casement)

For classic wall windows, the goal is to combine power with aesthetic discretion.

• Preferred Solution: Chain actuator. It’s the most common system for tilt windows (opening inward) or projecting windows (outward). The chain retracts into the motor housing when closed, keeping the frame design clean.
• Why Choose It: Easy to install, quiet, and adaptable to most aluminum, PVC, or wood profiles.

Automation for Skylights (Sloped Roofs)

Skylights face different stresses than vertical windows, such as glass weight pressing directly on the motor and weather exposure.

• Preferred Solution: Telescopic actuator (or piston) or reinforced chain actuator. For large skylights, the piston provides more robust linear thrust, ideal for countering constant gravity.
• Why Choose It: Offers greater resistance to wind push and ensures a watertight seal to prevent roof leaks.

Automation for Domes and Large Industrial Skylights

Domes, typical in warehouses or shopping centers, require a stroke (motor extension) often greater than standard openings.

• Preferred Solution: Rack actuator. This system uses a rigid toothed arm that slides linearly. It’s the “muscle” of opening automations.
• Why Choose It: The rack is virtually indestructible. It can lift heavy loads and connect multiple thrust points on the same dome via linking bars, ensuring no flexing during opening.

Installation Guide: Steps and Precautions

Installing a window motor is not to be underestimated. While modern kits are intuitive, precision is key.

What to Check Before the Installer Arrives

If you’re an end customer, before the technician arrives at home or the site, verify these points:

1. Power Supply: Ensure there’s an electrical outlet or conduit near the opening. Motors can be 230V (direct to mains) or 24V (ideal for heavy use or safety in damp areas).
2. Opening Condition: It must open and close manually without excessive effort or friction. If a window sticks or is warped, the motor will burn out quickly or the thermal protection will trigger constantly.
3. Clearance Space: Check for physical space on the frame or wall to mount the motor brackets.

Professional Installation Phases

1. Bracket Fixing: Install supports on the fixed frame and attachment on the moving part (sash).
2. Electrical Connection: Wire according to the manufacturer’s diagrams.
3. Stroke Adjustment: The most delicate phase. Set the “end-of-travel” points to ensure the window seals perfectly without straining the hinges.
4. Sensor Testing: If included, test rain and wind sensors to confirm automatic closing works correctly.

Who to Contact for Installation?

To ensure warranty validity and system safety (especially CE compliance), always use professional automation installers:

• Specialized Electricians: Many have smart home and automation expertise.
• Window Fabricators: Often capable of motorizing their own products.
• VDS Service Centers and Partner Installers: Choosing one familiar with VDS Automazioni products ensures optimal setup and immediate spares.

When NOT to Install a Motor?

Automation is great, but not always the right solution. Avoid or postpone in these cases:

• Structurally Compromised Openings: If wood is rotted or aluminum severely deformed, the motor won’t fix it—repair the frame first.
• Rusted Hinges: If hinges don’t rotate smoothly, motor force could rip screws from the frame.
• Lack of Safety in Human-Reach Areas: For automated windows below 2.5 meters from the ground, install with extreme caution (force limits or presence sensors) to avoid finger-crushing risks.
• Highly Corrosive Environments: In acidic vapors or extreme salinity (near the sea), use specially treated motors, or mechanics will deteriorate in months.

Maintenance: How to Make Your Motor Last

An electric actuator needs minimal care, but an annual routine can double its lifespan:

• Clean Chain or Rod: Remove dust and debris with a dry cloth.
• Lubrication: Use silicone spray or specific lubes on moving parts (avoid greases that attract dust).
• Seal Check: Hardened gaskets make the motor work harder to close—replace old ones.
