Double-Hung Windows for Residential and Multi-Unit Projects
Source double-hung windows for residential and multi-unit projects through Sibolla, a one-stop project supplier with its own factory and specialist production partners. We coordinate sash sizes, opening limits, glass specifications and cleaning access with your project team.
Custom Double-Hung Window Types
Aluminum Double Hung Windows
Engineered with slim, high-strength aluminum frames and optional thermal break technology. Both sashes slide vertically and tilt inward for easy cleaning, delivering efficient ventilation, durability, and low maintenance for modern residential and commercial projects.
Large Double Hung Windows
Designed for wide or tall openings with reinforced profiles and precision balance systems. Ideal for maximizing daylight and airflow while ensuring smooth, stable lift-and-tilt operation in expansive living spaces.
Small Double Hung Windows
Optimized for compact areas such as bathrooms, corridors, and stairwells. Dual operable sashes allow controlled ventilation and convenient cleaning without sacrificing structural integrity or insulation performance.
Double Hung Vinyl Windows
Multi-chamber vinyl frames engineered for energy efficiency and airtight performance. Low-maintenance surfaces with optional Low-E and argon-filled glass enhance thermal insulation while maintaining cost-effective durability.
Wood Double Hung Windows
Natural wood interiors with refined profiles and precision joinery for a timeless architectural aesthetic. Optional aluminum-clad exteriors provide added weather resistance, with customizable stains, finishes, and grille designs.
Black Double Hung Windows
Contemporary matte or textured black finishes paired with tilt-in sashes for easy maintenance. A strong visual statement that enhances contrast in modern and transitional interiors.
Triple Double Hung Windows
Three-lite configurations mulled into a single structural frame for expansive views and increased daylight. Flexible operable combinations—fixed center or fully operable sashes—optimize ventilation and façade symmetry.
Double-Hung Operation, Cleaning and Opening Controls
Confirm how each sash moves and how the selected window is cleaned. Our team can record these details with the glazing and hardware schedule before the order is approved.
- Upper and lower sash travel
- Tilt-in cleaning only where equipped

Why Choose Custom Double-Hung Windows
Custom double-hung windows combine classic aesthetics with practical performance. With operable top and bottom sashes, they provide flexible ventilation, easy maintenance, and enhanced indoor comfort.
For background on sash and opening configurations, see the overview of window types. Double-hung describes operation and should be kept separate from glazing specifications.
By working directly with a professional manufacturer, you gain tailored sizing, optimized glazing options, and durable aluminum frames engineered for long-term stability and energy efficiency.
The result is a window solution that elevates architectural style while delivering reliable airflow, security, and performance for residential or commercial projects.
Double Hung Windows Factory Design Options
Single Pane Glass
Cost-effective and lightweight glazing that delivers high light transmittance and a clean, traditional appearance. Ideal for mild climates, interior applications, or projects prioritizing clarity and budget efficiency.
Double Glazed
Two panes sealed with an insulating air or argon-filled cavity to significantly improve thermal insulation and sound reduction. Reduces condensation and energy loss, making it a reliable, cost-efficient solution for both residential and light commercial applications.
Triple-Glazed
Three layers of glass with dual insulated cavities deliver exceptional thermal efficiency and acoustic performance. Eliminates cold drafts, minimizes heat loss, and enhances indoor comfort year-round—ideal for cold climates, high-traffic areas, and energy-efficient building standards.
Frame Colors
Choose from an expanded color range—black, white, bronze, wood-grain, and custom finishes—to match any architectural style. UV-resistant, powder-coated surfaces ensure long-lasting color stability, weather protection, and low maintenance.
Frosted Glass
Enhance privacy while maintaining natural light. Frosted glass diffuses sunlight, reduces glare, and creates a soft, modern aesthetic—ideal for bathrooms, street-facing rooms, and minimalist interiors.
Tinted Glass
Reduce solar heat gain, glare, and UV exposure while maintaining clear outward views. Tinted glass improves indoor comfort, lowers cooling demand, and adds daytime privacy—ideal for sunny climates and south-facing façades.
Double-Hung Windows Project FAQs
Planning double-hung windows for a building project? These questions cover product selection, site coordination and the information our team needs before production.
Can double-hung windows be cleaned from inside?
Some systems have tilt-in sashes, but this is model dependent. Confirm the cleaning mechanism, sash weight and operating instructions before ordering, particularly where exterior access will be difficult.
Can both sashes be used for ventilation?
Double-hung windows normally allow both sashes to move. Confirm the actual operating range, locks and any restrictors on the chosen system, and check the project's ventilation and opening requirements.
What information do you need to quote double-hung windows?
Send sash sizes, opening limits, glass specifications and cleaning access, together with quantities, the destination and your required delivery date. We identify the details needing approval and confirm the scope, production requirements and quotation for your project.
Can we approve samples before ordering double-hung windows in bulk?
Discuss the required material or finish samples and any prototype at quotation stage. We confirm availability, cost and timing for the selected products. Record the approved sample and drawing references before production so inspection has a clear basis.
Can double-hung windows be coordinated with the rest of our project supply?
Yes. Sibolla combines its own factory with specialist production partners and one project supply team. We can coordinate this package with doors and windows and building materials. Confirm quantities, specifications and shipment phases together so the order follows your installation plan.
