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."

Insulation questions, answered by experts

The amount of insulation you need will vary depending on where you live. Energy Star recommends certain minimum insulation values in different geographic regions. In most cases, however, even adding a little insulation is better than not adding any.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

Cellular shades, especially double- or triple-cell varieties, are the most insulating window treatments. Their honeycomb structure traps air in layered pockets, creating a thermal barrier that reduces heat loss in the winter and blocks heat gain in the summer. For even more insulation, look for side-tracked cellular shades that seal the edges to minimize air leaks.
