This is our favorite subject. Why? Because infiltration
is so incredibly misunderstood. When we say misunderstood, do not
misunderstand; We acknowledge that the term blower door is not a mainstream
Words for the average homeowner. What is so incredibly misunderstood is that
are many heating experts, news public school writers and energy skills like
have completely missed the boat.
A fan door is a mechanical device that temporarily occupies one
outside the door of your home. It takes approximately 5 minutes to install the equipment.
When the house is prepared takes a few minutes usually, the fan is switched on
and the operator raises the speed until we reach a certain level
negative home pressure, usually 25 to 50 pascals.
Lets start with some basic tasks that do not take much building
knowledge to understand. Our Hampshire County homes and businesses lose heat in
winter months due to heat loss. Just like you need a jacket in cold condition
weather your body loses heat faster when its cold outside, the same holds true
true for buildings. Simply put: the colder its outdoors, the faster yours
the house will lose heat.
There are several basic elements for heat loss: the exposed surface of
walls, ceilings and floors and associated R-value, the glass you can see
the term glass boxes on manual J programs and the infiltration you can see
thermal air change per hour. Infiltration refers directly to how leaky or dense
the home is. The calculation depends on the total volume of the home high
or vaulted roof?. There is also ventilation to consider, but it is one
So now that we have a few reasons down, why are all beings? Where is 95% of
The world is going wrong when it comes to how delicious your home is? It has to do with
The idea that in general not all the leaks come from doors and
Windows. It also comes from the basement and on the wind as well. Than,
all we read instructs us to seal the leaky windows and doors. There is
a big problem with that teaching.
The average house will breathe on its own. Its a layer of physics. Otherwise, bet
live in submarines. Now, if we go buy a dozen tubes of caulk and spend
weekend squirting silicone in all the gaps at the window framing, we made slow
down the infiltration? You bet! Is our house narrower? It sure is! Is it healthier?
Probably not! Is it safer? Probably not!
In our example, we only plug the good air into our homes. Now granted,
some houses are so delicious that they could stand as the example was out there and
maybe still a lot too leaking. Its not the idea here to cover everyone
possible scenario, neither hopefully anyone reading this expects it.
We have to be technical here for a while. The fact is that when we slow down
infiltration at windows and doors, we accelerate infiltration in other areas
of the house. If you are not familiar with all methods that deal with people
Take advantage of building your house, you may not realize how many violations there are
