Vinyl Siding FAQs

What makes the 4000 Reinforced vinyl siding more durable?

Window World of Pittsburgh’s 4000 Reinforced Vinyl Siding is engineered and manufactured to provide not just beauty, but performance. A combination of a rolled-over nail hem and specially designed locking system provide superior wall attachment strength. In independent tests, the 4000 Reinforced siding withstood category 5 hurricane-force winds. This design also provides another, perhaps more important attribute, superior rigidity, helping to ensure straight course lines and even walls—on both new and existing homes.

What makes the 4000 Energy Plus vinyl siding more energy efficient?

Window World of Pittsburgh’s 4000 Energy Plus Siding features a contoured insulating underlayment designed to fill in the gaps left behind with traditional non-insulated siding. Its premium 1-1⁄4″ thickness is designed to provide an extra blanket of protection and impact resistance compared to traditional siding. The result is a siding system designed to withstand not only typical ‘around the house’ accidents, but also Mother Nature’s worst.

What design choices do I have?

Pittsburgh homeowners love the vast array of design options available in the 4000 series. For the reinforced vinyl siding, you can choose from traditional 4-1/2″ clapboard or elegant 4-1/2″ dutch lap profiles, two finishes, and a wide array of architecturally-pleasing colors. For our Energy Plus vinyl siding, you can choose from 24 beautiful options that allow you to create a look that’s truly personal.

Does vinyl siding require maintenance?

No more sanding, staining or painting. With vinyl siding, you can save time and money. Just wash it occasionally to keep it looking like new.

Will my purchase be protected by a warranty?

Both 4000 series products are backed by a lifetime warranty, including fade and hail protection. Protecting not only you but the next owner of your home as well.

The installation was a pleasant experience from start to finish. The installers started within the promised window of time and completed the work and cleaned up prior to leaving.

Window World Pittsburgh just finished our siding and boy does it look great! Installers were very professional and meticulous with their work. They patiently addressed any concerns I had and did a top notch job. I highly recommend Window World for both siding and windows.

From the original contact with the salesman to the installation, everyone that we dealt with was professional and courteous. The installation went smoothly and quicker than we expected. The crew showed up on time, cleaned up afterwards and were friendly and courteous.
