Interior Storm Windows
Thermolite's interior storm windows provide hurricane protection with laminated glass systems tested against Category 4 conditions. These retrofits install on existing window frames, maintaining exterior aesthetics while offering 20-25% energy savings. The system reduces air infiltration by 50% compared to traditional replacements, with STC 49 sound control ratings for noise reduction in urban environments.
Blast Mitigation Windows
Our patented blast mitigation windows use dynamic loading technology to withstand explosive forces without structural steel. Meeting GSA and DOD standards, these systems reduce installation time by 90% while achieving 50% cost savings. The compression release design prevents glass penetration during blasts, maintaining energy performance with U-values as low as 0.20.
Curtain Wall Retrofits
Thermolite's curtain wall retrofits enhance energy efficiency in commercial buildings by converting single-glazed systems to triple-glazed performance. This solution avoids exterior reconstruction, maintaining architectural integrity while reducing energy consumption by 20-23%. The system integrates with existing frameworks for seamless installation in mid-modern era structures.
Historic Retrofit Systems
Designed for preservation projects, our historic retrofit systems meet National Historic Preservation Act guidelines without altering original facades. These systems qualify for 20% federal tax credits while delivering 23% average utility savings. The non-invasive installation preserves historic materials and design elements across government, educational, and cultural institutions.
Signal Defense Windows
Thermolite's signal defense windows block electromagnetic leakage through patented glass technology, protecting sensitive data in financial institutions and government facilities. Originally developed for military applications, these systems combine EMI shielding with blast protection meeting federal standards, all while maintaining optimal visible light transmittance and thermal performance.
Questions
What is Thermolite's patented window system?
Our secondary interior window system retrofits existing windows with a custom frame and glass assembly, transforming them into high-performance units without exterior modifications.
How does Thermolite improve energy efficiency?
By adding an interior glass layer, we achieve R-values up to 5.0 and reduce energy loss by 20-25% through improved insulation and reduced air infiltration.
Can Thermolite windows protect against explosions?
Yes, our blast mitigation windows use patented compression release technology to meet GSA and DOD standards without requiring structural steel reinforcement.
Do installations require building evacuations?
No, our discreet interior installations typically occur during off-hours with minimal disruption to building occupants.
Are historic tax credits available?
Yes, our systems qualify for 20% federal and state historic tax credits while maintaining National Historic Preservation Act compliance.
How do Thermolite windows reduce noise?
Our laminated glass systems achieve Sound Transmission Class (STC) ratings of 49, significantly reducing exterior noise penetration.
