Why does my house lose heat when it gets cold?

As that warmed air leaves the interior wall, cold attic air moves into the cavity to take its place, resulting in more heat loss. This process continues as long as the attic stays cold and the house is warm. To fix the problem, you have to stop air from moving into or out of the interior wall cavities.

Why is there condensation in my walls in winter?

Condensation inside walls happens when there is a large temperature difference between the inside and the outside of the home. If the insulation inside your exterior walls is lacking, or it still allows for air movement like fiberglass and cellulose do, then condensation will be able to form.

Why do my walls sweat in winter?

What causes condensation? Condensation occurs when hot, moist air hits cold, dry air. This meeting causes water droplets to form on the cold surfaces (like your walls). This kind of moisture is what you'll find on the bathroom walls after a super-hot shower.

Does insulating walls stop condensation?

Critically this insulating effect reduces the chance of condensation forming as wall surfaces are warmer preventing water vapour in the air from changing into liquid.

How do I make my interior walls warmer?

Internal wall insulation is done by fitting rigid insulation boards to the wall, or by building a stud wall filled in with insulation material such as mineral wool fibre. Internal insulation: Is generally cheaper to install than external wall insulation.

Why does condensation form on a surface?

In all cases the root cause is because a surface has reached the “dew point” level aka where the surface is cool enough to allow condensation to form. Below is a chart many use to find out when this will happen & it is called a psychometric chart.

Why is one area cooler than the other?

Whether it is an interior wall or an exterior wall, the general catch is why is that one area cooler than the others? In many cases it could be a penetration not sealed, missing insulation, &/or it could also be that your area requires all electric to be run via conduit creating a nice air chase. One other overlooked item is if that wall is not cooler than the others, where might the moisture be coming from? Have a lot of plants in the area, a fish tank, that is where one lets their wet coats dry, or??? Figuring out the root cause will help you determine what the correct fix is.

Can you caulk cracks in fiberglass?

Can ’t I just caulk the crack to help stop the air-flow? In short the answer is yes you can & should (preferably after filling the gap in with low-expanding foam – not fiberglass ), just not at this time. You have two issues here, number one the area is wet and needs to dry out followed up by the issue of the temperature at the location – most caulks & paints want the surface to be at 55° or above.

Why is my attic cold?

You can go into the attic and look down into the interior walls and see the drywall. That means that cold attic air gets down into those cavities.

Why is fiberglass insulation always on top of the original ceiling?

The blown fiberglass insulation is almost always on top of the original ceiling because that’s the ceiling you see from the attic. In the course of modifying the houses, however, the workers opened many pathways for air to move from the attic to the space between the original ceiling and the current ceiling.

Do walls rob heat?

It seems so simple. There’s outside, and there’s inside. The walls, ceilings, and floors that separate the cold outside from the warm inside should be the only surfaces that rob heat from your home. Interior walls have conditioned space on both sides, so they shouldn’t be a problem, right?

Why does my house feel cold?

If the wall feels cold, chances are your home is not very well insulated. Why is this the case? In a poorly insulated wall, the warmth dissipates really quickly to the outside, creating a really cool wall in comparison to the room. If the wall is well insulated, a barrier is created that prevents the warmth from escaping, and this means the wall is going to hold the warmth and feel warmer.
