Royal Windoor: the Windows and Doors We Manufacture Ourselves
Thermally broken aluminum and vinyl, built at our Houston Heights shop, measured by the people who install them and warranted by the people who built them.
What Carries Our Name
Most of what we sell, we build. Royal Windoor is the brand on two of the three tiers we quote.
Our thermally broken aluminum line is the premium tier: 6063-T5 extrusion with a thermal break, German hardware, slim sightlines and the panel sizes that a wall of glass actually needs. It covers sliding, lift and slide, folding and minimal framed doors, plus casement, sliding and fixed windows and entry doors.
Our vinyl line is the middle tier, and it is a genuine product rather than a compromise. On a standard punched opening in a Spring or Katy house, vinyl is frequently the correct specification and aluminum is money spent on capability the wall will never use. That line runs to casement, tilt and turn, sliding and fixed windows, plus sliding and French patio doors.
Alongside those we are an authorized distributor for Elevate Windows & Doors, including the IMPACT Series. Distributing a third brand is what lets us tell you when our own product is the wrong answer for your budget.
Every Unit Ships with Dedicated Factory Submittals & Certified NFRC Labels
A Royal Windoor unit does not arrive anonymous. It arrives with our product-specific installation cut-sheet, engineering tolerances, and an independent NFRC energy certificate.
- A printed installation sheet per product, not a generic pamphlet: fixed window, tilt and turn, sliding patio door and outward opening door each have their own
- A recommended tool list and step-by-step guidance on every sheet, ensuring the unit is set to precision factory tolerances
- An independent NFRC energy label on the glass, verifying U-Factor, SHGC, visible transmittance, and air leakage ratings
- Exact rough opening guidance printed on the sheet, providing uniform 1/4-inch shimming and perimeter insulation margins
- One local company to call when something needs attention, thirty minutes from most of the houses we install
Manufacturer, Installer and the Same Phone Number
The reason we build rather than only distribute is that it removes the argument about whose fault a problem is.
Factory and field are one company
The extrusion, the glazing and the crew that sets it all report to the same family. There is nobody to hand the August complaint to.
Built to your opening
We do not hold catalog sizes and hope. Units are fabricated to the rough opening we measure, or to the numbers you send us.
Samples you can stand in front of
The office, the shop and the warehouse are one building at 7248 Wynnpark. Visit by appointment and look at the frames.
Warranty answered locally
We warrant the products we manufacture and the installation we perform. The term depends on the line and is stated on your job.

Buying It
Inside Greater Houston, Lake Conroe down to Galveston and Katy across to the ship channel, we measure, build and install. The measure is free, and if you would rather send your own numbers than wait on an appointment, our measuring guide is the same method our estimators use.
Outside that ring the product still travels. Supply-only shipping crates a Houston-built unit to any US address for a local installer to set. What does not travel is our crew, our flashing and our on-site warranty labor, and we would rather say that plainly than take the order and disappoint you.
Not sure which tier you need? The good, better and best comparison puts Elevate, Royal Windoor vinyl and Royal Windoor aluminum side by side, including the cases where the cheapest one wins. Or call (832) 681-9190 and describe the opening.
Royal Windoor as a Brand
Does Royal Windoor make its own windows, or only sell other brands?
Both, and the distinction matters. Royal Windoor is the brand on the products we manufacture ourselves in Houston: thermally broken aluminum and vinyl windows and doors. We are also an authorized distributor for Elevate, which is a different arrangement with a different manufacturer behind it. When you buy a Royal Windoor unit, the company that extruded the frame, glazed it and set it in your wall is the same company.
How do I know a unit is actually Royal Windoor?
Look at the paperwork stuck to the glass. Our units ship with a printed installation sheet carrying the Royal Windoor logo, a recommended tool list and step-by-step instructions for that specific product, alongside an NFRC energy label. It is not a generic sheet with a sticker on it.
Where are Royal Windoor windows and doors made?
At 7248 Wynnpark Dr in the Houston Heights. The office, the shop and the warehouse are the same building, so the people who build a unit are the people who answer for it. You can visit by appointment and look at the samples on the floor.
What is the difference between Royal Windoor and Elevate?
Price, origin and who stands behind the product. Elevate is Texas-made vinyl built in Grand Prairie and is our entry tier; we distribute and install it. Royal Windoor vinyl sits above it and Royal Windoor thermally broken aluminum is the premium tier, and we manufacture both. The three-way comparison is honest about where Elevate is the better buy.
Do Royal Windoor products carry NFRC ratings?
Yes. Our units carry National Fenestration Rating Council energy labels, which is the independent whole-window measurement of U-factor, solar heat gain, visible transmittance and air leakage. We do not print a single set of numbers on this page, because the figures belong to a specific product and glass package rather than to the brand. Ask us for the label that applies to what you are actually buying.
Can I buy Royal Windoor product outside Houston?
Yes, as supply only. We fabricate, crate and ship to any US address, and a local installer sets it. Installation, flashing and on-site warranty labor stay inside Greater Houston. See shipping.
