Aluminum Windows
Our aluminum windows combine commercial-grade durability with residential aesthetics, suitable for high-rises and homes. Featuring premium weather stripping and insulating glass, they reduce energy costs while offering noise filtration. Customizable with optional security screens and self-cleaning glass, these windows provide long-term value through energy efficiency and low maintenance requirements.
Vinyl Windows
We install Climate Solutions' 7000 and 8000 Series vinyl windows, offering fusion-welded frames for structural strength. These energy-efficient windows feature Low-E glass and Ultra Foam Spacers to minimize condensation, backed by lifetime warranties. Available in double-hung, slider, and casement styles to accommodate various architectural needs.
Steel Fire-Rated Windows
Optimum and D.V. Fyre-Tec steel fire-rated windows meet Chicago's strict building codes, providing 45-90 minute fire resistance at temperatures up to 1600F. These assemblies delay flame spread in emergencies while maintaining structural integrity, available in fixed and operable models for residential and commercial applications.
Window Repair
Our full-time service department handles vinyl and aluminum window repairs, replacing broken glass, hardware, and seals. Technicians source obsolete parts and perform onsite diagnostics for water leakage issues caused by construction defects rather than window failures, ensuring comprehensive solutions for aging systems.
Window Installation
We provide complete window installation services using factory-trained crews with decade-plus experience. Our process includes personalized consultations, product selection guidance, and management-led project oversight to ensure proper fitting and energy efficiency for both new construction and renovation projects.
