For over 65 years, LAS has been a trusted name in windows and shutters across the Gulf South. We don’t just sell windows: we build them, install them, and stand behind them for life. As a family-owned company rooted in Louisiana, we know what your home is up against: intense heat, humidity, hurricanes, and everything in between. That’s why every window we craft is designed specifically for Gulf South conditions. You’ll find our windows are built to last, built to protect, and built to look beautiful doing it.
From our state-of-the-art manufacturing facility to your final walkthrough with our certified installers, LAS brings unmatched quality, comfort, and peace of mind to every home we serve. Experience the difference of working with a team that lives where you live and puts your home first.
Built for the Gulf South, By the Gulf South
At LAS, we don’t just understand the Gulf South, we are the Gulf South. We’ve spent decades designing, manufacturing, and installing windows that can take the heat, stand up to storms, and stay beautiful for decades.
What sets us apart from national brands? We build every window right here in our own Louisiana facility. That means your windows aren’t sitting in a warehouse or crossing the country on a truck. They’re measured for your home, made to order, and crafted by people who live and work in the Gulf South. And because we control the process from start to finish, we’re able to guarantee consistent quality and solutions built for our unique climate.
Why local manufacturing makes all the difference:
- Regionally engineered materials – Built for high humidity, hurricane zones, and year-round heat.
- Custom fits for older homes – Precision sizing for historic or non-standard window frames.
- Direct customer support – Our team is never more than a short drive away.
Inside Our State-of-the-Art Manufacturing Facility
When it comes to quality, consistency starts at the source. Every LAS window and shutter is manufactured in our own Louisiana-based facility, where expert craftsmanship and strict quality control come standard. Unlike many companies that rely on out-of-state suppliers or mass-produced parts, we build everything locally. With precision, accountability, and pride.
From the first cut to the final inspection, our production process is fine-tuned for excellence. Our team of skilled local craftsmen, many of whom have been with LAS for years, bring both technical expertise and a deep understanding of Gulf South climate demands to every product they create.
We know one-size-fits-all doesn’t work. Each window is custom-built for its exact opening, which ensures superior energy performance, a cleaner install, and long-term durability. You won’t find retrofits or shortcuts in our process—only tailor-made solutions designed to last a lifetime.
Even more important? We’ve been doing this work here, in the Gulf South, for over 65 years. That means when we offer a warranty, we back it with a proven track record leaving you to not have to worry about a promise from a company that may not be around in five years. Our longevity is your assurance.
Here’s what sets our manufacturing apart:
- All products crafted in our Louisiana facility
- Decades of expertise from trained local craftsmen
- Custom-built for each opening—no retrofits or shortcuts
- Built to last, not just to be warrantied
The E-Glass Advantage: Engineered Efficiency
When it comes to energy efficiency, not all glass is created equal. At LAS, we use Cardinal® LoĒ³-366 glass, a top performing soft coat Low-E product engineered specifically for hot, sunny climates like ours in the Gulf South. This advanced E-glass technology reflects heat, blocks UV rays, and still allows beautiful natural light to pour into your home.
We also optimize performance by placing the E-coating on surface 2 of our double-pane insulated units. This position, on the inside-facing part of the outer pane, is ideal for blocking incoming solar energy and keeping cooling costs down. Northern manufacturers typically use surface 3 to trap heat in the home, but that’s not what Gulf South homes need.
The result:
- Reduces solar heat gain for a cooler interior
- Protects furniture and flooring by blocking UV rays
- Lets in visible light without glare or haze
- Outperforms ENERGY STAR standards by over 30% in our region
When you choose LAS, you’re not just getting a window, you’re getting a precision-engineered climate solution.
Real Customers. Real Results
When it comes to protecting and enhancing your home, nothing speaks louder than the voices of satisfied customers.

Installation Excellence That Sets Us Apart
Even the most advanced window will fall short without expert installation. At LAS, we believe craftsmanship doesn’t end when a product leaves the factory. It continues on-site with every meticulous installation performed by our certified team.
Our lead installers are graduates of the nationally recognized Installation Masters Certification Program, a comprehensive training course. To pass, installers must demonstrate expert-level knowledge in window design, construction methods, replacement procedures, and building code compliance with a minimum score of 90%.
This investment in training directly benefits homeowners:
- Fewer callbacks and installation issues
- Improved energy efficiency and airtight seals
- Long-term performance and fewer moisture or noise problems
But training is just the start. LAS installers are also known for their respectful presence, maintaining clean job sites and treating every home as if it were their own. Our attention to detail ensures that your new windows don’t just look good today, but that they’ll continue performing for decades.
We also rely on OSI Quad Max caulking, a professional grade sealing system known for its unmatched flexibility, durability, and weather resistance which is crucial in the humid Gulf South.
What “Unrivaled Quality” Looks Like in Action
At LAS, “unrivaled quality” isn’t a marketing slogan. It’s something our customers experience every day. It’s the sound of a window that seals with a solid click. It’s installers who treat your home like their own, down to the last sweep of the broom. We maintain strict quality control through every step of our in-house process. Every window is inspected, tested, and installed by highly trained professionals.
Hallmarks of LAS craftsmanship:
- E-glass with Gulf South–specific coatings for maximum solar heat protection
- Triple weatherstripping and double-pane construction to reduce energy loss
- Custom-built frames to fit your exact openings—no cutting corners
