Unvented Crawlspaces An unvented crawl space is a type of foundation design that is sealed and insulated. Unlike vented crawl spaces, which have openings that allow for air circulation, unvented crawl spaces are typically fully enclosed. Air circulation and humidity is controlled through a number of mechanical means within the crawlspace to accommodate for [...]
An on-site stormwater management system refers to a set of practices and facilities designed to manage and control stormwater runoff at or near its source, rather than allowing it to flow freely over surfaces and potentially cause erosion, flooding, water pollution, and damage to adjacent structures. These systems play a crucial role in protecting [...]
Expansion tanks and thermal expansion relief valves are used in water heater applications to address the expansion of water as it is heated. When water is heated, it expands, and without an expansion tank or expansion relief valve, the pressure in the system can increase, potentially causing damage to the water heater, pipes, or [...]
Air conditioning systems play a crucial role in maintaining comfortable indoor environments. To ensure their safe and efficient operation, it is important to follow the manufacturer's recommended guidelines, particularly when it comes to selecting the appropriate circuit breaker size. An electrical circuit for any electric powered appliance is protected by a circuit breaker at [...]
Two-pronged electrical receptacles, also known as ungrounded outlets, can present several potential issues due to their lack of grounding. The absence of a grounding conductor poses a safety risk as it increases the chances of electrical shock and may fail to protect against electrical faults. Inadequate grounding can also increase the risk of electrical [...]
Tempered glass is a type of safety glass that is manufactured through a process of controlled thermal and chemical treatments. The purpose of tempering is to increase the strength and safety properties of the glass. Modern building standards require safety glass to be installed in multiple locations around a home or building where personal [...]
Fences and gates are designed to grant or deny accesses to a given space. Their structural integrity determines their ability to fulfill these tasks. Fences are comprised of posts, horizontal braces, fence planks or pickets, hardware, and fasteners. The two latter elements are the crucial components that hold these individual members together to complete [...]
Roof anchors are devices or components designed to provide a secure attachment point on a roof for the purpose of supporting personal fall arrest systems (PFAS) or other safety equipment. They are an essential part of fall protection systems and are used to protect workers who perform tasks at heights, such as maintenance, construction, [...]
When a door rubs against its frame or the floor, it creates friction. Over time, this friction can cause wear and tear on both the door and the frame. The constant rubbing can lead to the paint or finish on the door being worn away, exposing the underlying material to potential damage. Similarly, the [...]
A high loop or air gap is a component used in dishwashers to prevent wastewater from flowing back into the dishwasher. It is a simple but effective method to ensure proper drainage and to prevent contamination of clean dishes. The high loop or air gap is typically installed in the dishwasher drain line, usually [...]
