Why project context matters
Start with the building, not just the product name.
A Bahamas project may need to balance coastal exposure, daylight, ventilation, security, energy targets, appearance, procurement and installation coordination in the same opening schedule.
What to send for a faster review
Project location, building type, drawings or photos, opening sizes, quantities, preferred operation, performance targets and delivery timing.
- Match each opening with the right operation: casement, sliding, folding, swing or entry.
- Review frame, glass, hardware, drainage and installation interfaces as one assembly.
- Confirm impact-related performance against the final approved configuration and applicable requirements.

Core benefits
A complete system is easier to review than a loose product list.
The final result depends on the selected frame, glass, hardware, anchoring and installation conditions—not on one product name alone.
Weather-focused review
Water tightness, air tightness, wind pressure resistance and drainage.
Thermal and solar control
U-Factor, SHGC, glazing build-up and frame design for comfort goals.
Security coordination
Locks, handles, hinges and operating modes matched to the opening.
Design flexibility
Aluminum finishes, glass choices, panel layouts and opening patterns.
Project documentation
Product data, drawings, quantities and packing information for coordination.
Configuration validation
Impact-related performance confirmed for the exact approved assembly.
Applications
Built around the people who move the project.
The same product family may serve different needs for a builder, hotel developer, architect or homeowner. Start with the project role and the opening schedule.

Questions before you quote
Impact windows and doors FAQ
Final product selection, testing documents, installation scope and delivery terms are confirmed for each project.
What are impact windows and doors?
Impact windows and doors are engineered window and door assemblies designed to address severe-weather performance goals through a coordinated frame, glass, hardware and installation configuration. DERCHI reviews the required configuration for each project rather than treating one catalog option as universal.
Can DERCHI supply impact windows and doors for Bahamas projects?
DERCHI supplies custom aluminum windows and doors for international residential, hospitality and commercial projects. For a Bahamas project, send opening sizes, drawings, location and performance requirements so the technical team can confirm a suitable impact-oriented configuration and documentation.
How do I choose the right impact window or door system?
Start with opening type, dimensions, operation, glass requirements, thermal and acoustic targets, hardware, finish and applicable local or project specifications. DERCHI can compare casement, sliding, folding, swing and entry door options during quotation.
Can impact windows and doors be customized?
Yes. DERCHI supports custom sizes, opening methods, aluminum profiles, glazing, colors, hardware and project packaging. Final customization is confirmed from approved drawings and the project brief.
How can I get a quote for impact windows and doors?
Use the Request a Quote action on this page or contact DERCHI directly. Include project location, quantities, opening schedule, drawings or photos, preferred products and required delivery timing.
What is the delivery time for a Bahamas window and door order?
Lead time depends on project scale, customization, drawing approval, production scheduling and shipping. DERCHI confirms the production and delivery plan after final technical details are approved.
How does DERCHI control product quality?
DERCHI describes a controlled process covering profile preparation, cutting, thermal break insertion, frame assembly, hardware installation, glass processing, inspection, packaging and shipment. Its published factory information also describes testing for air and water tightness, wind resistance, corrosion, durability and structural strength.
Does DERCHI provide after-sales and project support?
DERCHI provides sales and technical support for product selection, drawings, project coordination, packaging and international delivery. Installation, warranty and after-sales scope should be confirmed in the quotation and contract for the specific Bahamas project.
