At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

"Professional, timely and best installers we’ve had. Our installers took to time to get everything fit right. They had their hands full with a few doors and windows, due to bad framing from our construction contractor. Our new doors and windows work flawlessly now."

"Arrived on time as scheduled. They covered floors and railings with commercial moving blankets to protect floors and railings and did all necessary prep work and inspection in attic. Once all prep work complete, they started adding insulation. When all work was done they cleaned up everything and could not tell they were there other than the second floor was now much cooler. Will definitely recommend."

Insulation questions, answered by experts

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

You don’t need to remove old insulation before adding new insulation. As long as the old insulation is still in good shape—not wet, physically damaged, or moldy—then you can stack new insulation on top of old insulation to get a compounding effect. You can also mix different types of insulation, like adding blown-in insulation around existing fiberglass batt insulation or installing rigid insulation boards over rafters in your attic that already have batt insulation installed. If your existing insulation is very old or damaged, though, you’ll likely see more benefit from removing it and replacing it instead.

The R-value is a rating that measures the insulation’s thermal resistance (in other words, how well it insulates). For most pipe insulation, the R-value will fall between one and five. The higher the R-value, the more protection for your pipes. All pipe insulation materials should have an R-value listed in the product description or on the product label.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.
