Infrared Cameras and Home Inspections

Home Inspection

Infrared Cameras and Home Inspections.  Thermal imaging is the use of light rays that are invisible to the naked eye. There is an infinite range of light that is invisible to the naked eye. The wave lengths of light that are invisible to the naked eye are actually quite small. All light is identified by its wave length, frequency and energy.

Humans can only see light in the 400 to 750 nanometer range. Some animals can see light in the infrared spectrum and you can buy infrared film for you regular camera. An example of low-energy light rays is radio waves which are typically described by their frequency.

A prism placed into a ray of sunshine in a dark room reflects the colours of the rainbow using a property known as dispersion. This is the method Sir William Herschel utilized in the 1800’s in conjunction with thermometers to discern the presence of invisible light rays. He called his discovery the thermometric spectrum later to be known as infrared.

Using a infrared camera is a quick and easy method of determining the presence of air leaks in the exterior walls and ceilings of homes, also known as the building envelope. Although un-able to measure scope of leak it identifies where leaks are present. Infrared cameras are also an excellent means of finding moisture in walls and ceilings and are a valuable tool for professional home inspectors.

The benefits of employing infrared thermography in buildings are; Air leakage pathways present within a completed construction can be identified and rectified prior to subjecting the building to air permeability tests, reducing the risk of repeat testing being required; Depending upon the nature of the construction, even a building that meets or exceeds the building regulations may still be at risk of premature deterioration due to air leakage and subsequent condensation, therefore identifying where air leakage is occurring can be critical; Air leakage pathways can often indicate rainwater ingress pathways further adding to the potential benefits of an infrared survey; and Thermography is commonly used to identify air change rates with the help of the so-called ‘blower-door’ process, which creates under-pressure in buildings. Because the air pressure outside is higher than the pressure inside, the air will try to enter through unsealed areas. Using an infrared camera, this airflow can easily be seen, clearly revealing any unsealed areas, which can then be attended to before coverings and fittings make correcting this potential fault both expensive and time-consuming.

Heat Loss at brickThermal imaging cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 9,000-14,000 nanometers or 9-14 m) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects above absolute zero according to the black body radiation law, thermography makes it possible to see one’s environment with or without visible illumination.

The discovery of infrared started with a prism being placed into a ray of sunshine in a dark room which then reflected the colours of the rainbow using a property known as dispersion. This is the method Sir William Herschel utilized in the 1800′s in conjunction with thermometers to discern the presence of invisible light rays. He called his discovery the thermometric spectrum later to be known as infrared.

Thermal Imaging can be used for detection of potential equipment failure by measuring abnormal temperature signatures of electrical distribution system components. By evaluating the operating condition of these components, potential failure can be located and problem severity determined as part of a structured ongoing maintenance program.

When using a thermal imaging camera a special lens focuses the infrared light emitted by all of the objects in view. The focused light is scanned by a phased array of infrared-detector elements. The detector elements create a very detailed temperature pattern called a thermogram. It only takes about one-thirtieth of a second for the detector array to obtain the temperature information to make the thermogram. This information is obtained from several thousand points in the field of view of the detector array.

Light is often said to have a colour temperature. What this means is that the colour of the light is the colour of light radiated by a so-called black body which is at that temperature. Colour temperature is measured in Kelvins and the higher the colour temperature the bluer the light. Zero Kelvin is Absolute Zero and the freezing point of water is 273 Kelvins: a Kelvin degree is the same as a Celsius or Centigrade degree. In practice the actual temperature is not the same as the colour temperature.

Thermal Imaging has evolved into one of the most valuable diagnostic tools used for Predictive Maintenance (PM). Also known as Thermography, Thermal Imaging is the production of non-contact infrared, or “heat” pictures from which temperature measurements can be made. By detecting anomalies often invisible to the naked eye, thermography allows corrective action before costly system failures occur. Portable infrared (IR) imaging systems scan electrical systems, then constantly convert the thermal images to visible pictures for quantitive temperature analysis.

The Barrie Home Inspector was the first company in Simcoe County to offer Thermal Imaging as part of a Home Inspection.  Our training, experience and knowledge make us the Premier Home Inspection company for residential or commercial property investment.

Building Basics by Angus Real Estate Agents. If you are building a wall for a home addition, garage or other structure, it is important to be able to read construction drawings to identify all the dimensions for the walls which are given on the floor plan and elevation. The walls are to be laid out the same as on the floor plan, with all measurements followed exactly. The openings for doors and windows must be placed exactly. It is important that the corners be set on the foundation exactly as given on the detail drawing on the foundation plan. Taking measurements from the foundation or floor plan, and transferring those measurements to the foundation, footing or floor slab is the first step in laying out the wall.

Traditional stucco is made of lime, sand, and water. Modern stucco is made of Portland cement, sand, and water. Lime is added to increase the permeability and workability of modern stucco. Sometimes additives such as acrylics and glass fibers are added to improve the structural properties of the plaster. This is usually done with what is considered a one-coat stucco system, as opposed to the traditional three-coat method.  As a building material, stucco is a durable, attractive, and weather-resistant wall covering. It was traditionally used as both an interior and exterior finish applied in one or two thin layers directly over a solid masonry, brick or stone surface. The finish coat usually contained an integral color and was typically textured for appearance.

In the field of human-wildlife conflicts, probably the most common scenario nationwide is the squirrel in the attic.
Most people become aware that an animal is living in their attic when they hear scampering, or scratching noises above the ceiling. A wide variety of animals choose to live in the attics of buildings, from rats and mice, bats and pigeons, raccoon’s, opossums, and of course squirrels. Most of these animals will oftentimes use other areas of the home as well, from the soffits to the wall voids to the space between floors, so the attic is not the only area you’ll find critters.

A plumbing fixture could refer to a receptacle or device that is either permanently or temporarily connected to the water distribution system of the property, and which demands a supply of water.  Or the fixture could discharge waste water, liquid-suspended waste materials or sewage to the drainage system of the property.  The fixture could also require both a water supply connection and a discharge to the drainage system of the property.  Plumbing fixtures include water closets, urinals, bidets, lavatories, sinks, showers, bathtubs and floor drains.

There should be at least 15 inches of space from the center of a water closet, lavatory or bidet to any sidewall, partition, cabinet or any other obstruction. There should be at least 30 inches of space between adjacent fixtures. There should be a space of at least 21 inches in front of the water closet, lavatory or bidet to any wall, fixture or door. This clearance is for comfortable, adequate space for cleaning and use of the fixture.

A septic tank is used to hold wastewater while the wastewater’s solids and liquids separate.  The heavier solids in the wastewater, called sludge, sink to the bottom of the tank.  There it will slowly decompose.  A properly functioning septic tank will remove 75% of the suspended solids, oil and grease from the effluent.  The lighter, floatable material, called scum, rises to the surface and becomes trapped between devices at the tank’s inlet and outlet, either baffles or sanitary tees.  When wastewater enters the tank, it pushes relatively clean effluent, called “the clear zone” that located in the settling area between the scum and the sludge layers, out of the tank.
