Cape Cod homes are common throughout South Central Pennsylvania, and for good reasons. Originating in New England during the 17th century, Cape Cod style buildings are typically only a story and a half in height and tend to feature a moderately steep roof design. Cape Cod construction creates unique challenges in providing energy efficient living space and are often drafty and uncomfortable. Bonus rooms above the garage are also a common feature in our homes and present similar challenges as Cape Cod homes.

More often than not, the problem stems from a lack of effective air sealing and properly aligned pressure and thermal boundaries.

Why is it important to insulate Cape Cods and Bonus Rooms?

In most homes, the garage is considered to be an unconditioned space. It's where we park our cars, and it's also an area where we tend to store chemicals that can emit toxic fumes. Naturally, it makes the most sense to ensure that this area is separated from our living spaces—especially the bonus room that sits above it. While air sealing plays a huge role in this, so too does insulation.

Insulating a Cape Cod or bonus room not only helps to ensure that fumes don't enter the living space, but it will also make it much easier to efficiently heat and cool the room. If you're used to experiencing temperature swings and drafts in your bonus room, insulation and air sealing is the winning combination you're looking for.

  • Keith Williams,

    My wife and I purchased a leaky and minimally insulated older home and knew we needed to upgrade our insulation and have some air-sealing done. As a former home inspector who has also taken BPI/RESNET (weatherization) classes myself, I knew exactly what I was looking for in a weatherization/insulation company, and Energy Smart was it! From my initial inquiry to follow-up after the job, Jon and his team at Energy Smart took the time to do things right and provided both before  and after blower door tests to analyze the performance and effectiveness of their work.
