"We are so happy with our new windows from Wholesale Home Improvements. Our home is 51 years old and still had the old steel windows.  Our new windows are fantastic, we never close the blinds. This is a great company, honest and reliable. From Larry Summer, to Rebecca in the office to the install team-it was a great experience."

Hi Charlie,
I want to thank you and your team for doing such a great job with the windows.The windows are obviously efficient. This morning we had a few windows on the western side of the house opened until about noon, then buttoned everything up as the mercury began to rise. At 6pm it was 90 in the shade, but still 75 in the house. The thermostat was set to 78 so the AC never even kicked in! And these windows are quite soundproof, so the house is cool and quiet too. I can't say enough about these Serious Windows and doors. You can be sure anyone who asks about ours will be referred to you. Thanks again,
Maia - Denver

"I wanted to tell you how glad I am that I waited for your salesperson to give me a quote that saved me over $2,000 compared to that national chain. The new windows lowered our electrical bill this July by a 1/3 over last year. Thanks for your great product and service.

insulated siding Denver Colorado

Fullback® Insulated Siding is the most energy efficient siding on the market. It includes contoured insulation placed behind the exterior surface of the siding panel. Because the insulation is contoured to fill the gap between the siding and your home, it delivers maximum energy efficiency, along with durability, low maintenance and lasting beauty. Laminated Fullback® Insulated Siding is home siding that includes a rigid foam insulation, fused behind the exterior surface of the siding panel during the manufacturing process. Because the foam and vinyl are laminated together, Fullback® Insulated Siding offers greater structural stability. This allows for wider profiles and darker colors that weren't before possible with traditional vinyl siding. Easier to install Field-applied Fullback® Siding Insulation is a rigid foam insulation, placed behind any home siding during the installation process. Fullback® Siding Insulation can make any siding a Fullback® Insulated Siding. To learn more click here:
