Rainscreen Cladding Principle
A rainscreen is an exterior wall detail where the siding (construction), siding (wall cladding) stands off from the moisture-Hydraulic conductivity, resistant surface of an air/water barrier applied to the sheathing to create a capillary break and to allow drainage and evaporation. The ''rainscreen'' is the cladding or siding itself but the term rainscreen implies a system of building. Ideally the rainscreen prevents the wall air/water barrier from getting wet but because of cladding attachments and penetrations (such as windows and doors) water is likely to reach this point, and hence materials are selected to be moisture tolerant and integrated with flashing. In some cases a rainscreen wall is called a ''pressure-equalized rainscreen'' wall where the ventilation openings are large enough for the air pressure to nearly equalize on both sides of the rain screen,Brown, W. C, Rousseau, M. Z., and Dalgliesh, W. A., "Field Testing of Pressure-Equalized Rain Screen Walls," Donaldson, B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Furring
In construction, furring (furring strips) are strips of wood or other material applied to a structure to level or raise the surface, to prevent dampness, to make space for insulation, to level and resurface ceilings or walls, or to increase the beam of a wooden ship. Furring refers to the process of installing the strips and to the strips themselves. ''Firring'' is a U.K. term for wood strips which are usually 50 mm wide, tapered and fixed above wood roof joists to provide drainage falls below roof boarding. Furring strips themselves are typically referred to as ''battens'' in the U.K. and sometimes the material is called ''strapping'' in the U.S. In buildings Wood furring strips typically measure 1 x 2 or 1 x 3 inches. They can be laid out perpendicular to studs or joists and nailed to them, or set vertically against an existing wall surface. The spacing between the strips depends on the type of finishing material. Wider spacing is typically used behind the heavy boards tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Building Technology
Architectural engineering or architecture engineering, also known as building engineering, is a discipline that deals with the engineering and construction of buildings, such as environmental, structural, mechanical, electrical, computational, embeddable, and other research domains. It is related to Architecture, Mechatronics Engineering, Computer Engineering, Aerospace Engineering, and Civil Engineering, but distinguished from Interior Design and Architectural Design as an art and science of designing infrastructure through these various engineering disciplines, from which properly align with many related surrounding engineering advancements. From reduction of greenhouse gas emissions to the construction of resilient buildings, architectural engineers are at the forefront of addressing several major challenges of the 21st century. They apply the latest scientific knowledge and technologies to the design of buildings. Architectural engineering as a relatively new licensed profes ...

Building
A building or edifice is an enclosed Structure#Load-bearing, structure with a roof, walls and window, windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the :Human habitats, human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much architecture, artistic expression. ...

Interstitial Condensation
Interstitial condensation is a type of condensation that may occur within an enclosed wall, roof or floor cavity of a structure, which can cause a number of moisture-related problems. When moisture-laden air at dew point temperature penetrates inside a cavity of the structure, it condenses into liquid water on that surface. The moisture laden air can penetrate into hidden interstitial wall cavity through the exterior in a warm/humid outdoor period, and from inside the building during warm/humid indoor periods. Groundwater soaking the basement foundation walls from wet soil is common. This can result from a high water table or from improperly drained rainwater runoff soaking into the ground next to the basement walls. Moisture saturated basement walls will add moisture directly into basement interstitial spaces leading to interstitial condensation with cool basement temperatures. All interstitial condensation can cause uncontrolled mold and bacteria growth, rotting of wood com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtain Wall (architecture)
A curtain wall is an exterior covering of a building in which the outer walls are non-structural, instead serving to protect the interior of the building from the elements. Because the curtain wall façade carries no structural load beyond its own dead load weight, it can be made of lightweight materials. The wall transfers lateral wind loads upon it to the main building structure through connections at floors or columns of the building. Curtain walls may be designed as "systems" integrating frame, wall panel, and weatherproofing materials. Steel frames have largely given way to aluminum extrusions. Glass is typically used for infill because it can reduce construction costs, provide an architecturally pleasing look, and allow natural light to penetrate deeper within the building. However, glass also makes the effects of light on visual comfort and solar heat gain in a building more difficult to control. Other common infills include stone veneer, metal panels, louvres, and ...

Moisture Graph
Moisture is the presence of a liquid, especially water, often in trace amounts. Moisture is defined as water in the adsorbed or absorbed phase. Small amounts of water may be found, for example, in the air (humidity), in foods, and in some commercial products. Moisture also refers to the amount of water vapor present in the air. The soil also includes moisture. Moisture control in products Control of moisture in products can be a vital part of the process of the product. There is a substantial amount of moisture in what seems to be dry matter. Ranging in products from cornflake cereals to washing powders, moisture can play an important role in the final quality of the product. There are two main aspects of concern in moisture control in products: allowing too much moisture or too little of it. For example, adding some water to cornflake cereal, which is sold by weight, reduces costs and prevents it from tasting too dry, but adding too much water can affect the crunchiness of t ...

Exterior Insulation Finishing System
Exterior insulation and finish system (EIFS) is a general class of non- load bearing building cladding systems that provides exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system. EIFS has been in use since the 1960s in North America and was first used on masonry buildings. Since the 1990s, the majority of wood-framed buildings have used EIFS. History of EIFS EIFS was developed in Europe after World War II and was initially used to retrofit masonry walls. EIFS started to be used in North America in the 1960s, at first on commercial masonry buildings. EIFS became popular in the mid-1970s due to the oil embargo and the resultant surge in interest in insulating wall systems that conserve energy used for heating and cooling. In the late 1980s problems started developing due to water leakage in EIFS-clad buildings. This led to international controversy and lawsuits. EIFS installation was found to be a contributing factor in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capillary Action
Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like Gravitation, gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube such as a Drinking straw, straw, in porous materials such as paper and plaster, in some non-porous materials such as clay and liquefied carbon fiber, or in a biological cell. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by Cohesion (chemistry), cohesion within the liquid) and Adhesion, adhesive forces between the liquid and container wall act to propel the liquid. Etymology Capillary comes from the Latin word capillaris, meaning "of or resembling hair". The meaning stems from the tiny, hairl ...

Building Insulation
Building insulation is material used in a building (specifically the building envelope) to reduce the flow of thermal energy. While the majority of insulation in buildings is for thermal insulation, thermal purposes, the term also applies to acoustic insulation, Fireproofing, fire insulation, and Cushioning, impact insulation (e.g. for vibrations caused by industrial applications). Often an Building insulation materials, insulation material will be chosen for its ability to perform several of these functions at once. Since prehistoric times, humans have created thermal insulation with materials such as animal fur and plants. With the agricultural development, earth, stone, and cave shelters arose. In the 19th century, people started to produce insulated panels and other artificial materials. Now, insulation is divided into two main categories: bulk insulation and reflective insulation. Buildings typically use a combination. Insulation is an important economic and environmenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
