Wall Insulation is a primary component of your home’s thermal barrier set; hence inspecting it for damages is highly advisable. Anyway, thermal barriers may get affected by common insulation killers, no matter you examine for damages, frequently. So, how to recover from it is the factor to consider here. When compared to other insulation sets; wall and underfloor insulation often get deteriorated, as the inspection of those is not a straightforward task. For example, you can quickly inspect the roof or attic insulation by entering the attic. But, the underfloor compartment is a place that most homeowners often visit. Similarly, Wall Insulation often get missed by homeowners due to the difficulty in inspecting it.
The majority of the homeowners realize that there’s something wrong with Wall Insulation once they start to go through frequent temperature fluctuations. It is too late by then; temperature fluctuations usually cause by severely damaged insulation. Inspecting cavity-wall and solid-wall thermal barriers is not a piece of cake. For example, cavity-wall insulation gets installed by filling it through a hole; by pumping it with a blowing machine. Over time, that blown-in insulation can get settled due to gravity. Or, water ingress makes blown-in insulation to sink at a high rate. Unfortunately, recovering blown-in Wall Insulation after water ingress is not practical, most of the time. So, you will have to replace the damaged thermal barrier set, which would be the best choice to prevent future, frequent temperature fluctuations.
Batt Wall Insulation is the easiest to recover from water damages. And, modern batt insulation resists settling down due to gravity. But, the overall efficiency of it will go down to a greater extent due to water ingress. Why do the majority of the homeowners miss Wall Insulation damages? As mentioned, the difficulty in inspecting is the reason behind this trend. And, that is why you should focus on temperature fluctuations; turning on the heaters and air conditioners and thinking “now, it is fixed” is not the solution. Water ingress in batt thermal barriers will go away after a few days, but you should fix the cause of it ASAP. What can cause water ingress in Wall Insulation? Lack of ventilation could be a reason. Cavity wall structure has an opening for proper ventilation, and if this opening is blocked; moisture will not leave the cavity wall efficiently, and it might cause water ingress in insulation. Or, the origin of the water leak could be even from your upstairs bathroom. Tile damage and grout damages make the water get into the surrounding structure. If you ignore tile and grout damages; leaking water can even get into Wall Insulation. So, you should fix tile or grout damages first here; only then you can recover thermal barriers.
How about wildlife and pest attacks? Well, wildlife attacks on Wall Insulation are less common now. Anyway, pest infestations and mold growth can take place, still. While a pest infestation would not destroy the thermal barriers; the overall efficiency of those barriers may go down due to it. For all these inspections, you will benefit from hiring a home inspector. Let that home inspector recommend the right action to recover Wall Insulation from the pest attack. Rigid panel insulation has become the top choice when it comes to wall thermal barriers now.
