Interior Finish

With Marvin factory-applied interior finishes you can order beautifully finished windows and doors that are ready to install the day they arrive. What separates our factory-applied finishes from other manufacturers is that our proprietary multi-step, integrated conditioning and staining process begins before a door or window is even assembled. Every single piece of wood receives even coats of conditioning and stain, two coats of clear finish, and is sanded and baked twice in an oven before being built to your specifications. We do this because it is the only and best way to create a more consistent, durable and high-quality finish that brings out the natural beauty, texture, and grain of the wood.

When compared to painting or staining on the job site, factory-stained finishes offer consistent quality and performance resulting from our expertise with wood as a material and years of perfecting our staining process.

Every piece of wood receives even coats of conditioning and stain, two coats of clear finish, and is sanded and baked twice in an oven before your window or door is built to create a consistent, durable and high-quality finish that brings out the natural beauty, texture, and grain of the wood. Our stained wood products meet industry standards and arrive ready to install.

Painting on the job site or scheduling off-site finishing is an extra step that takes time and coordination. Choose our painted interior finish option on any Marvin pine windows and doors with a wood or clad exterior for a factory-painted option that arrives ready to install.

You can count on consistency with our process, as every piece of wood receives even coats of prime and paint, then is sanded and baked twice in an oven before your window or door is built to create a consistent, durable and high-quality painted finish that performs to the industry standard.
