The Absolutely Beautiful & PERMANENT Window Replacement Solution Near Portland & Vancouver:

Integrity Windows By Marvin.

Homeowner LOVE These Fiberglass Windows:

Fiberglass windows are growing in popularity, but some Portland & Vancouver homeowners haven’t been fully informed about the benefits of fiberglass windows yet.

We’re happy to educate people about fiberglass windows and we recommend them as the best choice on most homes. They’re very strong - typically between 3 to 8 times stronger than alternate window materials. They look beautiful and have a durable finish. Fiberglass windows are also an excellent choice for energy efficiency.

One aspect of fiberglass windows that we especially like is they have very low thermal expansion. That means in hot and cold temperatures these frames expand and contract very little. This low expansion rate prevents gaps from forming between the frame and glass. That means moisture stays out and the window glass stays crystal clear - no more foggy windows.

The ‘Best of the Best’ Fiberglass Windows? Hands Down, It’s Marvin.

We believe the best fiberglass windows on the market are manufactured by Marvin. Integrity Windows by Marvin are made from Ultrex, a pultruded fiberglass material. These windows are 8 times stronger than vinyl, 3.5 times stronger than wood/vinyl composites, and 3 times stronger than wood. In fact, it’s comparable in strength to carbon steel.

Integrity Windows require virtually no maintenance, won’t expand & contract, and look like beautiful wood windows.

Also, with the glass packages offered by Marvin, expect amazingly energy-efficient windows in Portland or Vancouver. Customers can see up to 30% savings on energy bills, and expect industry-low seal-failure rates of .2%.


Beautiful Windows

Integrity by Marvin windows have a patented, mechanically bonded inline acrylic that is up to three times thicker than competitive finishes. This extra-thick, bonded finish means superior resistance to discoloration, scratching, and denting.

Integrity Windows have a crisp and clean appearance, with tight, mechanically-bonded corners and narrow frames to maximize glass viewing area.

A Warranty With Teeth

Fiberglass is the perfect material for windows for Portland OR and surrounding communities. Durable, strong, and low thermal expansion – fiberglass barely expands or contracts during temperature changes. It keeps the seals between the frames and the glass airtight and water is kept out.

The strength and durability of these windows makes it possible to offer a Lifetime Warranty. Of course a warranty is only as good as the company that backs it – and Marvin has been around for more than 100 years.

Why Marvin Is Such A GREAT Company

There is another reason we love Integrity Windows by Marvin. This manufacturer is family-owned and operated (just like us) and they stand by their people. Located in Minnesota, during the severe economic downturn they sacrificed profits and didn’t lay-off or fire any of their staff.

In other words, they stuck to their values even in tough times. That is my kind of company and one we trust for their dedication to quality, and they back their products and their people!
