There are several places where moisture might gather that are frequently missed in standard inspection procedures or need significant property damage to identify them. Insulation issues are likely to cause your home’s extreme summer or winter heat, as well as any mold or condensation issues. But how will you be able to be specific without breaking down your walls? Because of this, many people are using thermal image detection for insulation as part of their routine building inspection.

To create photographs of objects even in low-light situations, thermal imaging uses infrared radiation and thermal energy to gather data about the items. It’s a technology that, through time, has amassed various applications. Being able to function in complete darkness (because it doesn’t rely on visible light) and in smoke, fog, smog, and haze makes it a potent form of night-vision technology.

Why is appropriate insulation crucial?

Insulation keeps areas comfortable all year round by preventing hot and cold air from penetrating your walls. You will spend more on heating and cooling if there is no insulation detection in your walls since you will lose or gain heat through them. Poor insulation can result in hazardous and unsanitary conditions in your home and increase energy costs. Homes without adequate airflow management frequently experience mold growth, which can be ugly and harmful. Mold can aggravate allergies and asthma and lead to fatigue, headaches, and breathing issues.

There are a few warnings that indicate you should examine your insulation more closely. This can be one of the first signs in colder weather if you awaken to noticeable condensation on your windows. Similarly, if you experience dampness in your home during the winter or find that your laundry and other wet goods take a long time to dry, you probably have an insulation issue.

How does thermography operate?

Infrared energy, also known as heat and emitted from all objects, is the foundation of thermal imaging. The quality of the radiation emitted usually correlates with the total amount of heat an object emits, and it is also known as the heat signature. Thermal imagers, often known as thermal cameras, are sophisticated tools with sensitive heat sensors that can detect even the slightest temperature variations. They can build an image based on the variations and inflections of the temperature values as they collect infrared radiation from objects in a particular environment.

Thermal image detection for insulation typically come in grayscale, with white denoting heat, black denoting cooler regions, and shades of grey indicating temperature gradients between the two. To help viewers more readily identify distinct objects, newer thermal imaging cameras add color to their images. These colors include orange, blue, yellow, red, and purple.

Areas of common insulation leakage

There are a few places in the house where there’s more likely that there won’t be enough or any insulation. The thermal camera would be wise to inspect any area where a wall and roof converge. Because attached garages are sometimes forgotten when installing insulation, they could be another location where heat is wasted. The insulation in your home may suddenly have gaps even if appropriately installed because insulation can settle and change over time. Additionally, you may have compromised the effectiveness of the insulation if you made changes to the house after you put it. Downlights are a typical illustration of this, which purposefully let temperature transfer between the room and the roof hollow. Although the light fixture aesthetically covers the hole, it is thermally less temperature resistant than the ceiling’s plaster surface.

Windows are one of your home’s most robust barriers against heat loss. If you weren’t there when your house was built and are unsure of how many glazing coatings are on your windows, it might be challenging to determine how much heat is lost through them. Thermal cameras can measure the heat loss through your windows, including the insulation surrounding the windows and the glass itself. You can stop up to 30% of your home’s heat loss using proper window insulation.

Using thermal imaging to assess buildings

The process of finding structural flaws is known as forensic inquiry. You may do it for a homeowner complaining about a roof leak, a business that just had flooding, or to gather evidence for a lawsuit. One can typically encounter defects in the following places:

  • Low, sloping roofs
  • Electrical issues
  • A variety of outside components that are deteriorating, allowing water incursion;
  • HVAC or plumbing issues;
  • Insulation detection issues;

You may use conventional inspection methods and infrared cameras in various building inspection and forensic investigation components linked to structural collapse or moisture issues. While infrared cameras might not have all the answers, they can help building owners save time and money by allowing them to identify problems more quickly and precisely.

Can cameras using thermal imaging see through walls?

No, but to be fair, they don’t actually “see through” anything. If you point a thermal imaging camera at a wall or solid surface, it will measure the heat radiating outward from that surface. A thermal image detection for insulation measures the surface temperature of the first item in its line of sight.

Exterior thermographic photography rarely provides valuable information about what is happening inside and vice versa. The reason behind this is that the design and insulation of most structures is to trap heat. Here are a few warnings: Because the wall would also immediately begin to heat up, you can use an IR camera to detect intense heat from behind a barrier (such as in the case of a home fire).

Similar to this, some thermal cameras may detect heat emitted by a person, for example, standing against the cold, opposite side of a sufficiently thin wall, but only if they remain there long enough for their body heat to pass through the wall’s materials at that location partially.


Using thermal insulation imaging to check your home’s insulation is a valuable tool for keeping it comfortable all year. To make sure you comprehend what the thermal camera is telling you and what you need to do with that knowledge, you can operate a thermal camera on your own or with the assistance of a professional.
