Vanguard Windows

Vanguard Windows - Industry Leading Performance, Exceptional Design, Superior Construction, Comprehensive Warranty... There Is No Equal


Prestige Products is the Exclusive Authorized Vanguard Dealer for the Denver-metro market.

If product innovation, high-quality performance and exemplary customer service are most important to you when making a window purchasing decision, then you'll love the product strength, beauty and craftsmanship of Vanguard Windows - the finest replacement window systems for your home.


Our exquisitely designed Vanguard replacement window systems are backed by our TotalCare Warranty, which is a comprehensive warranty package that covers any material defects (including all vinyl frame components), seal failure of the Insulated Glass Unit (IGU) for any reason, and any accidental glass breakage or screen tears, for as long as you live in your home. Plus, it is fully transferrable (not just 1 transfer like everyone else). Compare our warranty to the "Limited Lifetime" warranties other vinyl manufacturers offer and you will see the difference. Better yet, compare Vanguard's true lifetime warranty to the "10-year" frame, hardware and moving parts warranties of non-vinyl product manufacturers and you'll begin to understand why this superiorly crafted window leads the industry in performance, looks, return on investment (ROI) and overall VALUE! There is no better product in the replacement window industry... period.

And there is no better company to trust with the purchase and installation of your new windows than Prestige Products Windows & Siding.

Are Vanguard Windows REALLY Better?

You bet they are! Here's why:

Fully Insulated Frames

Vanguard injects all of the chambers in their mainframes (a true 100% fill) and one chamber in their sash frames with UltraCore, a proprietary, closed-cell Polyurethane Foam that gives the Vanguard window frame an industry leading 7.14 R-Value. When you insulate the frame, you increase the overall ability of a window to halt energy transfer and ultimately keep the interior pane of glass warmer in the winter and cooler in the summer.

Fiberglass Reinforced Sash Frames

Vanguard is the only vinyl frame window on the market that inserts a fiberglass reinforcement bar into the frames of the operational sashes to increase strength and rigidity. The FiberCore fiberglass reinforcement rod infuses the best aspect of the fiberglass and composite framed windows (strength and rigidity) into the vinyl frame to give Vanguard a "best of both worlds" approach. Our vinyl frames can still be fusion welded (melted together at the corners), can still be totally maintenance free, can still be 100% foam insulation injected, and can still be much more affordable than the fiberglass and composite frame competitors, and yet have the strength no other vinyl window offers.

VG12 Glass w/Argon Gas & Glass Guard Spacer

Advancements in glass coating technology have allowed glass manufacturers to continually increase the number of layers of Low-E coating they apply to interior surfaces of residential window glass, thus increasing the overall effectiveness and energy efficiency of the Insulated Glass Units (IGUs) they produce. Vanguard has taken this technology to the limit by introducing VG12 glass as a standard feature in all their windows. VG12 (also referred to as Omega12) is a 12-layer glass coating system, complete with Argon Gas fill and the industry's highest performing spacer, the Glass Guard stainless steel continuous spacer system (no breaks, cuts or notched corners in the entire spacer circumference). This amazing Low-E coating and IGU system allows for maximum UV protection, maximum energy transfer protection (VG12 has a 1% energy transfer rating) and maximum strength and durability, while still allowing maximum ambient sunlight into your rooms.

Incredibly Low Air Infiltration Rates

Most window manufacturers (and salespeople) don't talk about air infiltration in regards to trying to get you to buy their window. Why? Because most replacement window products on the market today don't have very good air infiltration ratings. Vanguard Windows have the best air infiltration (also referred to as air leakage) rating of any window by any manufacturer, period.

The maximum allowable air infiltration rating suitable for residential installation (and to get an NFRC ratings sticker) is 0.3. The only three ratings the NFRC gives are 0.3, .02, or 0.1. Any window with an air infiltration rating BELOW 0.1 still gets that blanket number assigned to it's certification sticker. That's OK for most windows, since they fall at or above a 0.1 anyway. But for Vanguard, it is unfortunate that the number on the ratings sticker doesn't accurately reflect the true rating and it doesn't tell the whole story.
Vanguard Windows have a 0.03 Air Infiltration Rating. That's right - far closer to a 0.0 than a 0.1. Since Vanguard Windows have better weatherstripping than most other windows, and have NO sash slop (the movement back and forth in a closed and locked double operational window), the result is the best air infiltration rating on the planet.
It makes a big difference!

Opti-View "Invisible" Screens

Screens on windows are just part of life. We all have widows and all operational windows have screens. We want to open our windows and look out our windows, but if we could we would all probably ditch the screens so we didn't have to look through them and so we could get the most airflow possible. But the bugs... those nasty little bugs. So we put up with heavy screens (which, before now are all that have been available) so the bugs stay outside when we open our windows. NOT ANYMORE!
Behold the OptiView Screen from Vanguard -
a breakthrough in window & patio door screen technology. OptiView screen mesh is significantly less dense (much more fine) than traditional fiberglass screen mesh. Consequently, the OptiView Screen from Vanguard is up to 50% easier to look through
(it virtually disappears) and it lets roughly 40% more air flow through the screen, optimizing ventilation. This revolutionary screen gives you what you really need in a window or patio door screen - bug coverage; yet it minimizes what you don't like about your screens - having to look through them and having airflow restricted by them. The OptiView Screen from Vanguard Windows is the closest you can come to not having a screen on an operational window at all!

Low Profile, Beveled "Wood Look" Interior & Exterior Frame Design

Many homeowners realize the benefits of vinyl as the frame material of choice for their new windows (fusion welded corners, high efficiency, maintenance freedom, lifetime warranties, etc.), but some of them just don't like the look of "typical" vinyl windows. If this describes you, Vanguard couldn't agree with you more. The aesthetic appearance of the Vanguard frames (both main frames and sash frames) are unlike anything else in the vinyl window industry, and they bring a design concept to the table that no other window manufacturer offers. Vanguard is quite simply the best looking window on the market. The main frame is narrow and has a 45o chamfer on the inside edge of the interior that gives the frame a designer look and feel. On the exterior, the main frame has a double contour that really sets it apart from the crowd. The sash frames are also very narrow (low profile) and have a beveled edge that looks like a routered wood window sash. The Vanguard window was designed to emulate a painted wood window look, with more "flair" and "designer aesthetic" than a traditional vinyl window that consists of squared off 90o corners and very basic lines. By the way, even though the Vanguard frame lineals are low profile, they are still super energy efficient (due to 100% fill foam insulation) and super strong (due to the fiberglass reinforcement bar) - the best of all worlds. Looks aren't everything, and Vanguard knows that if you have a great looking window that is just an average performer, you still won't lead the pack. But to combine the best looks in the biz with the highest performance is what makes a Vangaurd window a Vanguard window.

Recessed Locks & Top Quality Components 

H.A.A.R.T. Valve - Altitude Is NOT A Problem

If you are shopping for replacement windows in the Dener metro market, and you happen to talk to salespeople that represent "local manufacture" (meaning windows manufactured in Denver or surrounding areas) you have undoubtedly heard the horror stories of windows manufactured at a lower altitude performing poorly and even "exploding" at higher altitudes like here in Denver (we are, after all, the "Mile High City"). Dealers who sell locally made windows will very often use scare tactics to try and lead homeowners to believe that a window made in the midwest US (Ohio, Michigan, Illinios, etc.) will suffer from seal failure, Argon gas leakage, bowed-out glass units (from non-equalized pressure), or even explosions... oh my! NOTHING COULD BE FURTHER FROM THE TRUTH. Please do not believe salespeople (who's main motivation is a paycheck) when they tell you these half truths and scary, albeit fictitious, stories. Prestige Products has installed tens of thousands of Argon-filled windows manufactured in the midwest right here in Denver (at roughly 5,800-6,000 ft of elevation) and we have NEVER had a problem with seal failure, Argon leakage or bowed-out glass units. It is not until over 7,000 ft of elevation that this would realistically become an issue of concern. ENTER THE HAART (High Altitude Argon Retention Technology) VALVE from Vanguard Windows. The HAART Valve is a one-way valve that was invented by (and patented by) the manufacturer of the Vanguard window that equalizes pressure in an Argon-filled IGU at ANY elevation up to 13,500 ft. So, it is absolutely clear that our Vanguard windows, manufactured in Temperance Michigan, with the proprietary one-way HAART Valve, will perform as well as (and in most cases far better than) any window manufactured in Denver. We have scientific proof... they have scare tactics. You decide.
