Does insulation make condensation worse?

Advances in housing insulation have led to a large increase in condensation problems. Homeowners Warned to Act to Prevent Humid Talking. Ironically, condensation and humidity are getting worse as houses become better insulated. Too long; I didn't read, yes, too much insulation can cause condensation.

This is because excessive insulation leads to poor ventilation inside the house and, as a result, prevents humid air from escaping to the outside and becomes more prone to condensation on cold surfaces and walls. Insulation is used to prevent condensation. However, if installed incorrectly, it can cause condensation and moisture problems on the walls, attic or basement. When this happens, it is usually because the installation has been applied too much, leaving the condensation on the outside with nowhere to escape.

But this can be avoided if you consult with a professional HVAC expert. Even after isolating the system, condensation may form as a result of miscalculation or poor installation. If the engineer does not take into account the extreme humidity conditions of the space or if the system operates outside normal design parameters, the thickness of the insulation will not be sufficient to compensate for the increase in water vapor in the air and condensation will form as the surface temperature drops below the point of dew. The insulation must also be installed correctly; any gaps in the insulation or any small openings in the vapor retarder will cause condensation and must be sealed immediately.

New government schemes that promote the use of insulation and force us to install insulation of loft walls and cavities are causing enormous problems with condensation. Of course, you should always be on the lookout for the types of interstitial condensation. This is not moisture caused by the insulation, but rather a specific form of moisture that takes root inside the insulation, where warm and humid air settles on the colder insulation and can become a bigger problem over time. You can read more about interstitial condensation and how to avoid it here.

Yes, insulating your home can lower humidity, especially if the insulation includes vapor diffusion retarders. Because insulation reduces heat transfer, it moderates temperatures throughout the house, so moisture and dampness are less likely to develop. The insulation of the cavity also creates an enchanting atmosphere for little creatures: many nests of lovely mice, rats, you name it, they love things. This is all the more vital if you also improve the insulation of your cavity or loft at the same time, as many homeowners do.

A roofing expert can take a look at the vents (or lack thereof) in your eaves and see if you have adequate airflow that allows moisture to escape before condensation forms. One problem that can result from moisture ingress is corrosion under insulation (CUI) or corrosion forming on the surface of the system when water is trapped between the surface of the system and the insulation. However, if too much insulation is laid and other measures are taken, such as replacing old drafty windows with modern airtight double glazing, it is quite possible that your home will experience problems related to lack of ventilation. If excess moisture and moisture in your home makes your daily life uncomfortable, insulation, such as water vapor and fiberglass barriers, can help.

Now, of course, the salesman of the company blowing in isolation will be very upset by all of this - he and his company are in cahoots with the government subsidy scheme that is flushing millions of pounds of taxpayer money down the toilet - they don't want you to stop buying their scrap paper they get paid to that fall apart on your walls. Condensation is a complicated problem on the roof, because it tends to look and act like a leak, even if there is no damage to the roof. You didn't realize there were so many types of insulation, from spray foam to wadding. The ingress of moisture into porous materials can cause CUI, since the insulation is kept in the water right next to the system, wrapping the metal with a damp cover and providing the means to form corrosion.

Correct insulation thickness, with vapor retarder if necessary, will prevent the formation of condensation on duct surfaces, just like piping systems below ambient temperature. To avoid this, heads of household should strive to maintain harmony between insulation and ventilation. The insulation creates a barrier that slows the transfer of warm air from inside the house to the outside. A quick Google search will reveal that there are hundreds of companies specializing in the removal of cavity and loft insulation.
