The Science of Solar Heat Gain in Modern Homes
In warmer regions across North America, windows are the primary source of radiant heat transfer into a home. When direct sunlight penetrates standard glass, shortwave solar radiation converts into longwave heat energy upon striking interior floors and walls, creating a greenhouse effect that forces air conditioning units to run continuously.
According to energy efficiency studies, stopping solar heat before it penetrates through glass using external or interior motorized solar shades installed by INTERBLINDS SHUTTERS is significantly more effective than relying on HVAC systems to cool down already overheated rooms.

How Wireless Sun Sensors Work (Somfy® Sunis RTS)y
At INTERBLINDS SHUTTERS, we partner with Somfy®, the world leader in quiet motors and intelligent controls. With over 50 years of engineering excellence and 270+ million happy users worldwide.
Secure Radio Technology (RTS): Long-range, interference-free radio frequency (up to 65 ft) that communicates effortlessly through walls without extra wiring.
Extremely Tested: Every motor undergoes rigorous quality testing to withstand thousands of cycles under demanding climate conditions.
Seamless Integration: Fully compatible with your existing HVAC, lighting, and home security systems.
Automated Timers and Astronomical Scheduling
While sun sensors react dynamically to cloud cover and light intensity, automated timers provide structured, routine window management that aligns with your household schedule and solar paths.
Timer Capabilities
- Astronomical Sunrise/Sunset Clock: Automatically shifts shade schedules as seasons change and day lengths vary across the year.
- Zoned Scene Control: Group south-facing living room shades to lower at 11:00 AM while keeping north-facing office shades open for glare-free natural light.
- Vacation Mode Integration: Simulates occupancy while you are away by raising and lowering shades at varied daily intervals, augmenting home security.
Energy Savings & Comfort Comparison
Operating Method | Solar Heat Reduction | HVAC Energy Impact | Convenience Factor
|
|---|---|---|---|
Manual Operation | Inconsistent (Shades often left open) | Minimal impact (High AC usage) | Low (Requires manual adjustment) |
Basic Timers | High (Predictable solar control) | 15% to 20% AC cost reduction | High (Set-and-forget schedules) |
Sun Sensors + Timers | Optimal (Real-time solar response) | Up to 30% AC cost reduction | Maximum (Fully autonomous) |
