Other Reasons To Buy Milgard Windows and Doors

  • Milgard puts their logo and other identification on their products. Even if you forget the brand you bought and lost your receipt, the windows are identifiable. Notice how many companies do not brand their product. Are they worried about their window performance in the future?
  • Milgard is a well known, national brand with the same name for over 45 years. Other brands have changed their name to leave behind problems.
  • Low-E is standard in Milgard windows. While argon is available at a small upcharge, we do not push it – or any other features – that some consider “gimmicks.”
  • All products are made custom for you. This means that replacement sizes are not a problem. Windows are made in 1/8” increments, at no upcharge for special sizes. And your windows fit much more exactly.
  • Two lines of vinyl windows are available. The price difference is about 40%. We will be happy to show the features of both lines. Both have the same Milgard warranty.*
  • Milgard is a national company. Milgard brand products are common throughout the Denver metro area. Many homeowners and contractors are familiar with the brand. Milgard has been used in many Parade of Home locations over the past few years.
  • Front Range Lumber sells only the Milgard brand, as they are the BEST brand available to satisfy the needs of our customers.

Fiberglass Patio Door Tips

Quality Milgard brand fiberglass windows have lots going for them: Lifetime parts and labor warranty, EnergyStar rating, low E glass and custom sizes at economical costs. So why consider upgrading to fiberglass windows?

The “Ultra” is an all fiberglass patio door. More expensive than vinyl, they have the same qualities listed above. Should you spend more and upgrade to fiberglass?

Milgard’s peerless warranty* for the original purchaser of the window (with 10-year transferability from date of manufacture) and the perceived longer life of a fiberglass product make them a more popular choice all the time. Fiberglass’s reputation for strength, paintability, imperviousness to UV rays and chemicals and overall durability should add extra value to a home for years longer than vinyl and wood windows can.

Here is a review of important qualities of fiberglass:

Paintability: While five EXTERIOR factory finishes are standard, many choose white to leave as is or to paint.  Painting is as easy as on wood, but you should expect a longer life. Wood can soak up water and humidity, leading to peeling. By getting fiberglass, you are leaving yourself and future building owners open to any color wished.  Painting does not affect warranty unlike most brands “clad” windows that are voided if painted. You can even paint Milgard’s black!

Strength: Vinyl doors can only slide. Fiberglass is strong enough to swing also, giving you all options for exterior doors. Poor quality or dark colors can make vinyl products warp or bow; this cannot happen with fiberglass due to its extremely low thermal expansion and contraction rate. Vinyl windows are joined at corners by heat, melting the pieces together. Fiberglass corners are joined with gaskets, sealants and a mechanical attachment with screws.

Warranty: Most patio doors in the price range of an “Ultra” have a 20-year glass, and 10-year non-glass warranty. Please read Milgard’s warranty. It clearly exceeds these limits.*

Some patio door brands require installation by a factory representative. This traps you and can really increase the total cost. As long as they are properly installed, any contractor or homeowner can install Milgard patio doors and have a lifetime warranty!*

Energy Star: The federal government has established criteria for a recommended minimum level of energy saving qualities in windows and doors. These criteria are not required but are met in the fiberglass line, Low E Max glass and “super-spacer” ensure this desirable designation.

We, as a small family-owned business have partnered with Milgard. They take care of us and our customers.

By installing yourself, or arranging a separate contractor, you can get great windows at the lowest price!
