In our recent discussions about insulation we mentioned that in vertical applications (exterior walls) we prefer to use Roxul “rock wool” insulation and in horizontal applications (the attic) we prefer sprayed in Cellulose. And on several occasions, we have walked away from sprayed in Foam.
We have been talking about Energy Efficiency, Cold Air Penetration, Heat Recovery Ventilation systems, and a host of other Energy concerns all of which are very very important!
When you consider building your new home how much direct attention is paid to complying with all of the various Building Codes? Here at Vermont Modular Homes we believe there are basically two ways to build a home:
Yesterday we started a conversation about how an Heat Recovery Ventilation system will control the moisture in your home. Basically, the HRV will exhaust stale air from inside your home and bring in fresh air. The concept is really simple and I suppose you could accomplish the same thing by simply opening a window. But, when you open the window you are creating a huge hole in the building envelope and tons of warm air will escape. That would not be a good idea if you are trying to be energy conscious.
Yesterday we had another home set on its permanent foundation. This home is located in Southern Vermont up in the mountains. You may recall seeing a post of ours last week when the home was delivered. We received several email inquiries and phone calls with questions about this house.
Yesterday we set both of the modules on the foundation and assembled the ceiling and roof of the great room. The front half of the house is going to be a fully vaulted ceiling and a wall of glass looking out at the view.
Here we are in the kitchen the room that many consider to be The Heart of a Home. Lots of families all but live in the kitchen, it is where people gather, dinners are made, families congregate around the dinner table, and many a cup of coffee is had along with an occasional Adult Traveling Beverage. The Kitchen Island is something that never happened in Grandma’s house, it is an idea born of the 21st Century where the kitchen is an integral part of The Great Room rather than a separate room.
We have been down in the basement so let’s stay there.
Remember, we are chasing holes in the building envelope where Cold Air can Penetrate and rob your home of precious heat. Our goal is to:
- stop Cold Air Penetration,
- cut back on Heat Loss, and
- be more Energy Efficient!
I can quickly think of three more possible culprits that need to be Foamed Shut:
This week we have been talking about Cold Air Penetration down in the basement. And there are several really important facts to always keep in mind as you work to make your home more Energy Efficient:
Today we continue our quest to significantly cut down on Heat Loss and one of the easiest ways is to stop Cold Air Penetration. That’s why we are still down here in the basement.
Yesterday we fixed our basement windows and I mentioned that there are probably huge holes for cold air to penetrate into the house. I am talking about a genuinely huge hole; not quite big enough to drive a truck through but a big hole for a ton of cold air.
Let’s see if we can find another place in the basement where Cold Air Penetration goes on all the time. Yesterday we talked about how dense cold air penetrates into the warmth of the house.
Don’t forget that in all of our conversations there is a major rule to understand; when it comes to movement of air – cold always moves towards warm! Cold air is more dense and warm air is less dense! The fact that cold air always moves towards warm air is exactly why we need to stop Cold Air Penetration. Let’s go look ……………….
We are continuing our task of stopping Heat Loss, or more realistically reducing Heat Loss to a minimum.
Last week we started a series about Winterizing our homes with the goal being to reduce Heat Loss to a minimum. One of the single most important things we can do is to cut down on Cold Air Penetration. As Cold Air enters the house, almost always down in the basement, it is cold and dense.
