Why Semper Windows Matter

When it comes to windows, not all glass is created equal. Semper Windows installs high-performance, military-grade quality windows designed to protect your home and family from California’s unpredictable climate, and the unexpected.

Our Semper Secure Window Package includes:

- AutoSense™ Locks: Self-latching locks that engage automatically when closed, no more wondering if your windows are secure.

- KeepSafe Maximum® Glass: Reinforced laminated glass that can withstand hurricane-force winds, deter break-ins, and reduce outside noise.

- Sound & Security Glass: Dual-layer laminated technology that blocks 99% of UV rays, reduces glare, and keeps your home quieter and cooler year-round.

Every installation is handled by Semper’s certified professionals, never outsourced contractors. You’re not just getting new windows, you’re getting Semper protection, American craftsmanship, and peace of mind that lasts a lifetime.

Strong, Silent, and Energy Smart, That’s Semper Windows 

Upgrading your windows isn’t just about looks, it’s a smart financial move that pays for itself over time.

Here’s what California homeowners gain with new high-efficiency Semper Windows: 

- Lower Energy Bills: Insulated, airtight designs reduce heating and cooling costs year-round.

- Increased Home Value: Boost your property’s resale appeal with modern, energy-efficient designs.

- Better Comfort: Keep your home cool in the summer and warm in the winter.
 
- Enhanced Security: Reinforced laminated glass adds a layer of safety against break-ins and weather damage.
 
- Noise Reduction: Keep out the chaos of California traffic, neighbors, and outdoor noise.

You’ll notice the difference the moment they’re installed, quieter mornings, cooler afternoons, and a noticeably smaller electric bill.

Semper Cares: Giving Back to America’s Heroes

The Semper Cares Initiative was founded to provide relief to veterans from high energy costs by awarding them with the security of energy independence. We need the public to help identify these warriors to tell their stories and make a difference in their lives.
