Questions
Where are you based, and where do you ship?
We are in Springfield, Missouri. We serve Southwest Missouri and ship nationwide.
What is uPVC?
uPVC is unplasticized polyvinyl chloride, a strong, rigid plastic made to resist moisture, weather, corrosion, and rotting. Unlike wood frames, it needs minimal maintenance.
How is a tilt-and-turn window different from a typical American window?
It opens two ways. The tilt position opens the top inward for ventilation while the bottom stays secured. The turn position swings the whole sash inward like a door. Most American windows slide or hinge in only one way.
Do you keep windows in stock?
Yes. We import popular configurations in bulk and hold them in Springfield. Stock changes, so ask which sizes and configurations are available.
Can I visit the showroom?
Yes, by appointment only. The showroom is at 3107 E Chestnut Expy, Ste P-Q, Springfield, MO 65802. Call 417-210-3194 to schedule a time.
Can I order custom sizes and colors?
Yes. Custom orders let you choose dimensions, frame colors, window configurations, glass, opening mechanisms, and hardware. Exact options depend on the product.
What certifications do your products carry?
Certification and code compliance depend on the specific product and glass configuration. We only state a rating when we have documentation for that product. Ask for it for the product and project you have in mind.
Do you install?
Yes, on applicable projects. Installation can include removing and disposing of old units, installing the new ones, flashing, insulation around the frame, and exterior weather sealing. Interior trim, structural changes, and finishing are specified separately.
Do you work with homeowners?
Yes. We work with homeowners who are building or renovating, and with builders, contractors, architects, and developers.
