With many door styles in common and interchangeable glass design between collections, you have the flexibility to find the perfect door in the perfect texture, without compromise.

What do you get with a Fiber-Classic door? 

Weather Resistance – Composite rails protect the door at the top and bottom edges to help block moisture that can wick the doors.

Security – An enhanced lock block combined with a 1-1/4″ engineered lumber lock stile increases rigidity and stability.

Durability – With very little maintenance, a fiberglass door can bring a home years of durability. Unlike wood, fiberglass will not warp or rot. And unlike, steel, it will not dent or rust.

R-values – Built with a polyurethane foam core that offers up to four times the insulating R-value of wood, Therma-Tru fiberglass insulate against the cold and heat for exceptional energy efficiency.

I just spoke with Dave V. by phone, but wanted to be sure that my appreciation did not go unnoticed. Jeff and Mark of your residential division just left my home after spending two days replacing several storm damaged windows.  I am calling and writing to express my deep appreciation for their professionalism, expertise and spirit.  They are both an asset to your company.  With a positive experience like the one I have experienced, you can bet that if there is additional work that I need done, Omni will be my first call.   ~ Thom N. Oshkosh, WI

My recent experience with Omni Glass & Paint was fantastic. I had been waiting 3 months for a part for our front door from another glass company in Oshkosh. I reached out to Omni Glass & Paint; they came to look at the door, found the part and installed the part in less than a day. The door works perfect now. I was so impressed with Omni’s work and would highly recommend them to anyone. – Matt Bakalars, Fox Valley Savings Bank

Mark and Jeff installed windows in our home in Oshkosh.  We were extremely happy with their work but more than that, they went above and beyond to install those windows and were extremely friendly and informative along the way.  They even found an issue with rotten wood that the workers who installed our siding just covered up…so we are very grateful. Because of their services we would highly recommend Omni Glass to everyone.  And the windows are outstanding too!   ~ Roxanne D. – Oshkosh, WI

I just called to compliment the man who installed my new shower door.  Jeff was very pleasant, he did an AWESOME job, everything is perfect, and he left the place neater than when he arrived!  Everything lines up, everything fits, nothing leaks! I am so happy with the job he did!   ~ Nancy, Oshkosh, WI

I just wanted to congratulate the great crew we had working at my home, they were fantastic.  I am very, very pleased with their knowledge and abilities, they were the most impressive group of people I have ever worked with. Mark was especially helpful, he was absolutely wonderful to work with. Thanks again!   ~ Rick, P
