Extract of sample "Insulation and ventilation"

Insulation and Ventilation Insulations are necessary for heat regulation by resisting the flow of heat. There are different types of insulation based on the resistance to heat flow denoted as ‘R’. Department of Energy states that insulators should be purchased based on their resistance, and some require professional installation while others are easy to install. Batt insulation is made from fiberglass or mineral wool and available in different widths and a resistance rate of 3.15 to 3.85 (Department of Energy, 2008). Loose fill insulations are loose fibers and pallets made from fiberglass, cellulose or mineral wool. Their resistances range from 2.13 to 3.31 and mostly require installation by professionals (Department of Energy, 2008). The other type of insulation is rigid insulation that is made from plastic foams or fibrous materials. They provide a greater resistance where space is limited. Professionals apply foam insulation produced in two forms open-cell and closed-cell with the help of special equipment.
Blue Flame states that ventilators are those openings in the attic that allow moisture to escape. Ventilation ensures that attic heat does not penetrate into living rooms during the summer. Natural ventilation installation should be for every 300 square feet of an attic, one square foot of ventilation is required (Blue Flame). Some of the natural ventilation types include gable vents, ridge vents, soffit vents, and roof line vents. Power ventilation utilizes attic ventilators that may hinder efficient fireplace and furnace ventilation (Blue Flame).
Properly ventilated and insulated attics offer several benefits. Proper insulation and ventilation prevent ice dams by keeping the roof cooler during winter. An efficient ventilation and insulation reduce cooling costs during warm seasons. Proper insulation extends shingle life span that also prevents rot in the roof’s framing by reducing moisture build up. Improper ventilation and insulation consequences include increased costs in cooling and heating the house during hot and cold weather. Improper installation consumes energy and produces unreliable outcomes inhibiting energy efficiency.
Both open cell and closed cell foam insulation are suitable for insulating. These foam installations all come in different colors and often look alike. Easley states that in open cell foam insulation, bubbles are linked and connected by air pockets with Resistance values of around 3.5 per inch. The closed cell foam spray uses tiny bubbles filled with gasses less conductive than air, forming a resistance of 6.5 per inch (40). A closed cell spray is hard to crush while open cell spray foam compresses easily. The closed cell spray insulation’s high resistance makes it favorable to contractors and family owners. This insulation is also great for making a home more storm-resistant, and it does not store water (Easley 40).
Safety tips while installing insulations emphasis on the need to follow the specified directions and terms of use by the manufacturer. Electrical safety should be ensured by keeping a safe distance from electrical wirings and ensuring electrical connections are in proper conditions before plugging and unplugging equipment. Personal protection equipment such as masks and gloves should be used at all times. Easley suggests that cellulose should be maintained three inches away from chimneys, and all insulation kept at a safe distance away from heat sources (40). All insulation and ventilation should meet the federal and all laid out specifications. Other personal protection equipment includes eye protection and wearing loose fitting long sleeved and legged clothing.

Non invasive Ventilation

...? Non-invasive ventilation Introduction Non-invasive ventilation, abbreviated NIV, is the administration of ventilatory support to the lungs without the use of an invasive artificial airway (tracheostomy tube or endotracheal tube) (Soo Hoo, 2010). It can either be non-invasive positive pressure ventilation, abbreviated NPPV, which refers to ventilation with positive airway pressure and without tracheal tube; or negative pressure ventilation, referring to ventilation in which negative pressure is applied to the thorax (Jones, 2009). Soo Hoo (2010) explains that NIV has now become an essential tool in managing chronic and acute respiratory...

Ventilation Activities

...Discuss your department's procedure for ventilation activities at a structure fire typical of your area. Who, what, when, where, and how. When ventilating a single family residence, at least two individuals need to work on the roof. As far as commercial structures are concerned, a minimum of 3 personnel (with at least one being a company officer) must work on the roof. Furthermore, the company officer needs to be the first individual to the roof when a commercial building is involved. The officer needs to determine the structural integrity of the building to help with safety of the other workers. When working on the roof, the crew must then identify two escape routes. Also, they must have with them a...

High Frequency Oscillatory Ventilation

...Prof’s High Frequency Oscillatory Ventilation (HFOV) The lungs are just one part of the respiratory system and the site of gas flow and exchange. The primary goal of the respiratory system is to deliver oxygen to the blood and to remove carbon dioxide from the blood to the environment. Sometimes, for a variety of causes, the lungs will fail. At this point, the person will have two options: die, or be temporarily transformed into a cyborg. Those who choose the latter are placed on a mechanical ventilator, which allows control over the pressure, volume, and rate of air delivered to the alveoli. The volume of air in a single breath is known as the "tidal volume." Conventional ventilators...

Ventilation-Perfusion

...Ventilation-Perfusion Metabolic rate plays a significant role to individual trying to loose weight. Metabolism is essential in maintenance of proper bodily functions such as circulation, respiration, cellular reproduction, and tissue repair. Individuals with the intention of weight loss mainly focus on boosting their metabolic rates (Connolly et al 196-201). Resting metabolic rate for an average person account for a large percentage of the total daily energy uses (Connolly et al 196-201). This is a key determinant of energy balance and weight change. Decreased resting metabolic rate is a challenge to weight management. Several factors affect resting metabolic rate and some include body mass, body composition, age, gender...

Passive ventilation

...By Location of the Passive Ventilation The passive ventilation system is a type of ventilation that is composed of openings that are mostly located in wet rooms. They are usually connected via vertical ducts to the roof terminals. Warm and moist air is drawn up these duct by the combination of the wind and stack effect. Dry air is then drawn into the system via background ventilators that are located in habitable rooms. A gap should be given at the bottom of the internal doors to allow free passage of air through the system. Therefore, it is important to maximize the air flow by designing the house with openings at different levels. This cans also be done by using...
