We’ve been installing windows across the Carolinas since 1978. In that time, we’ve tested just about every brand on the market. We became a ProVia Direct Dealer in 1996—nearly 30 years ago—because no other manufacturer matched their combination of energy performance, structural engineering, and warranty commitment. In fact, ProVia is a 16-time ENERGY STAR® Partner of the Year—a distinction that proves their products aren’t just efficient, they are industry-leading.
Being a Direct Dealer means we buy factory-direct from ProVia’s manufacturing facilities in Ohio. No middlemen. No distributor markups. That direct relationship means better pricing for you, priority access to ProVia’s latest innovations, and a level of product expertise that only comes from working with a manufacturer for three decades.
ProVia has recognized that commitment with their Platinum Plus designation—the highest performance-based recognition they offer, reserved for the top dealers in the entire country. Speaks is the only Platinum Plus and certified ProVia installer in the greater Charlotte area.
SMART $AVER APPROVED: We are Duke Energy’s approved participating contractor for qualifying window replacements. Your new ProVia windows may qualify for significant rebates.
LICENSED GENERAL CONTRACTOR: If we find rot, water damage, or structural issues behind your old windows, we’re licensed to repair it—all under one roof, one project, one warranty.
If energy performance is your top priority, the Endure series is the window we recommend most. It’s ProVia’s flagship vinyl replacement window, engineered to exceed ENERGY STAR 7.0 requirements in every climate zone — including the Southern zone that covers North Carolina.
In our climate, keeping solar heat out of your home matters more than insulation alone. That’s why the Endure’s combination of low SHGC (Solar Heat Gain Coefficient) and low U-factor is so important — it blocks unwanted heat from the sun while still insulating against heat transfer. The result: lower cooling bills in summer AND lower heating bills in winter.
Endure windows can be configured to meet ENERGY STAR Most Efficient criteria — the highest performance tier available.
Core ProVia quality—INNERGY® thermal reinforcement and SunShield® vinyl—at a more accessible price.
U-factors in the 0.27–0.29 range.
ComforTech™ Warm Edge Glazing.

FACTORY-DIRECT SINCE 1996: Nearly 30 years. No distributors. No middlemen. Better pricing.
PLATINUM PLUS: ProVia’s top-tier award. The ONLY certified installer in greater Charlotte.
47 YEARS: 7,000+ projects. 200+ five-star reviews.
OUR OWN EMPLOYEES: Every installer is a full-time team member trained at ProVia’s factory.
NO-PRESSURE GUARANTEE: In writing.
LIFETIME WARRANTY: ProVia’s transferable lifetime warranty plus our workmanship guarantee.
The Problem: The homeowner was dealing with outdated, drafty windows that were causing high energy bills and fading the home’s exterior.
The Speaks Solution: We performed a full-home replacement using ProVia Endure™ Vinyl Windows—specifically selected for their ENERGY STAR 7.0 certified glass package and 700x better thermal reinforcement.
We hear these a lot. So, we figured we'd put the answers right here to save everyone some time.
All four ProVia window lines — Endure, Aspect, EcoLite, and Aeris — can be configured to meet ENERGY STAR 7.0 certification for the Southern climate zone that covers North Carolina. That means a U-factor of 0.32 or lower and an SHGC (Solar Heat Gain Coefficient) of 0.23 or lower. In our climate, SHGC is the number that matters most — it measures how much solar heat the glass blocks, which directly impacts your cooling bills. ProVia’s Endure and Aeris lines go even further, achieving ENERGY STAR Most Efficient status — the highest performance tier available. ProVia is a 16-time ENERGY STAR Partner of the Year. As a Platinum Plus Direct Dealer, we can walk you through the exact glass packages and performance ratings for every line and help you choose the right configuration for your home and budget.
Four tiers. EcoLite is the smart-value line. Aspect is the mid-range sweet spot with INNERGY®. Endure is the top-tier performer with the best combined U-factor and SHGC for North Carolina’s climate.. Aeris is luxury with real wood interiors. All carry ProVia’s transferable lifetime limited warrant
Our own employees — never subcontractors. Every Speaks installer has been trained at ProVia’s factory in Sugarcreek, Ohio and carries ProVia’s certified installer credential.
Direct Dealer means we buy factory-direct from ProVia with no distributor or middleman. Platinum Plus is ProVia’s highest performance-based dealer designation. Speaks has been a Direct Dealer since 1996 and is the only Platinum Plus certified installer in greater Charlotte.
Most single-window replacements take 1–2 hours per opening. A full-home project (10–20 windows) typically takes 2–4 days. Manufacturing lead time is approximately 4–6 weeks.
Transferable lifetime limited warranty covering the vinyl frame, hardware, and moving parts. Insulated glass carries a 20-year limited warranty against seal failure. Plus our own workmanship guarantee on top.
