Understand the Types of House Additions

Are you planning to shift to another house, because of less space in your house, you are finding it difficult to accommodate. If your answer is positive, just stop a while: moving to another house may not be the solution, you can maximize space in your house by adding an extra room to your house. House addition is much cheaper than buying a new house or staying on rent.

In this article, we will help you understand the types of house additions that you can add to your existing house.

A porch is an extension to the living space area. You can add porch in the front and rear side of the house. It enhances the appeal of your house. You can enjoy outdoor living space. Porch is usually used for entertaining, playing and seating purposes.

Sun room/Conservatory
Sun room and conservatory look similar, but there is a small difference between them. Sun room is an enclosed room built with windows and glass walls. These rooms allow direct sun light into the indoor space. To put it in simply, the sun room is an indoor living space where you can enjoy outdoor view from the sun room. Conservatory allows more light in your house, but it is mainly used for growing plants. Total conservatory is made of glass.

A deck is an extension of outdoor living space where you can have parties and entertain your guests. Decks usually don’t have ceiling and flooring. You can add walls or simply partitions to your living space. It is less expensive and you can add it to add value to your house.

A bump-out is extending/moving your walls up to a few inches/feet to add extra space to house interior. That is, you can increase the dimensions of your room or house by adding a bump-out.

Dormers add usable space on the sloping roofs. They are meant for decorative purposes or for functional spaces. You can also add windows to dormers for architectural finish. Dormers makes your house look beautiful.

Patio and backyard both are similar. These are the open space between house and the garden mostly used for relaxing, dining and entertainment. Some patios are enclosed, but don’t confuse with porch. However, patios are always connected with front door or rear door of the house.

Orangeries and conservatories look alike. However, their roofing structures are different. While orangeries roofing structure provides insulation from sunshine to the interior of the house, conservatories don’t do so. Orangeries interiors look fabulous and more impressive than that of conservatories.

Single room
If you want to add extra room to your house, a single room is the best option. You can use this room as your bedroom, garage room or store room.

Second story
Adding one more level on the top of the first floor of the house is second story. This is mainly used when you want to add more rooms on the top of the first floor roof. To construct second story, you need the support of first floor basement, walls and roofing.

You can get house addition done as per your requirements; these additions will not only change the look of your house, but will add value to your house as well.

Get to Know about Types of HVAC systems

ID Fan manufacturersHVAC (Heating, Ventilation and Air Conditioning) systems are designed to perform four main functions – heating, cooling, ventilation and controlling humidity levels. HVAC systems are designed to meet goals of its customers and satisfy them in terms of efficiency of system and saving energy. Many HVAC systems are available today and are designed for both homes to industries. Selection of HVAC system is critical because improper selection may cause discomfort in terms of health and loss of money. This article tells you about types of HVAC systems.

Though there are many type of HVAC units, there are four broad categories.

Constant air volume (CAV) HVAC systems

Constant air volume HVAC systems work by use of constant supply of air volume by distributing hot or cool air. Constant air volume HVAC systems are installed in large spaced rooms (auditoriums, theaters, lobbies, hospitals, manufacturing units, etc.). There are three variants of CAV systems: single duct, reheat and multi-zone systems.

  • Single duct system: A single duct CAV is a simple central air conditioner with single zone distribution for either cool or hot air throughout the building at a fixed temperature (usually 55O F). This fixing of temperature allows to maximize cooling load in all spaces.
  • Reheat system: The reheat system is modified single-zone distribution system that uses electricity or water to heat coils. Reheat coils reheat the cool air flow and distribute controlled air throughout the building. It is used in hospitals, laboratories and other buildings, which require wide load variation.
  • Multi-zone system: Multi-zone system has two distribution systems, one for heating and other for cooling. Both ducts are designed to meet at one place called “mixing box”. This mixing box controls and distributes the required air temperature throughout the building.

Variable air volume (VAV) HVAC systems
Variable air volume systems are economical to install and are more energy efficient to bring down the cost by 10 to 20% compared to constant air volume systems. This system is best to meet varying cooling and heating needs of building areas.

The design of VAV system is simple and has small units that make installing easier. The main air duct provides cooling at 55O F and this is called primary air. A thermostat controls the temperature of primary air delivered to each room. This modulates the volume of air supply to get the required room temperature in different rooms according to cooling needs.

The main advantage of using VAV comes by its efficiency in dehumidification and temperature control by fan that efficiently reduces over all cooling or heating bills.

Radiant air conditioning (RAC) HVAC systems
Radiant air conditioning system refers to temperature controlled surface (hot/cold water or electrical heating coils tubing) that heats or cools indoor air temperature before air goes into the room. Radiating air conditioners install metal tubing on the surface of ceiling or walls of home or offices.

In this system, as air passes through metal pipes along the the concrete ceiling or walls, it gets warmed or cooled before it goes into the indoor environment. From these tubing, heat or cooling is transferred from ceiling or walls to warm the indoor air. The use of RAC has many advantages – no duct work is required, quite and energy efficient, no need of cool air exchanger, zoning capabilities and finally even temperatures for comfort. RAC is a power saving system that allows users to get comfortable temperature at home under lower temperature.
Advanced radiant RAC systems make it possible to control individual room in buildings. There are different types of radiant air conditioners and the most common types are electrical and gas fired systems.

Zoned System
Zoned system is a single area where temperature is regulated by singe thermostat. If a building’s temperature is controlled by a single thermostat, it is called single-zone. When multiple thermostats are used in a building, it is termed as multi-zone system.

In single zone HVAC system, single thermostat maintains same room temperature across different zones of same building. While in multi-zone system, each room is equipped with one thermostat to receive air with different temperatures based on the need of users.

Multi-zoned system is more advantageous over single-zone, as multi-zone system can efficiently control air-conditioning requirements. They are able to direct hot or cool air for certain rooms when needed. This offers wastage of power utilization for cooling or heating your building.

Use of zoning system enables you to save around 30% or more cooling/heating on power bills. Since zoned HVACs run based on your requirements at single or more rooms, it makes HVAC to run at lower speed and thus run quietly, and hence ergonomically good.

Know the Common Types of Toothpaste

There are many varieties of toothpastes available and you could choose one according to the condition of your teeth. Each toothpaste has its different composition. If you have experienced sensitivity in your teeth, there is toothpaste for teeth sensitivity. If your teeth become dark, there is toothpaste for teeth whitening etc. It is, therefore, in your hand which toothpaste to choose, according to your teeth condition. The common types of toothpastes are as follows:

Toothpaste for sensitive tooth
If your tooth became sensitive to cold or hot foods, it is caused by the porosity in your teeth, as the dentin in the teeth is made up of lots of the tiny tubules, which lead directly to the sensitive pulp area which contains nerves. Under the situation, this kind of toothpaste helps block the tubules as they toothpaste contain potassium nitrate, that is useful in reducing the painful situation which are associated with this condition.

Toothpaste for Teeth Whitening
This is designed for people who find stains on their teeth even though they don’t smoke. This may be because of consuming foods or drinks like tea coffee or coal. These teeth whitening toothpastes contain high amount of abrasives and cleansers that helps you in removing the strains on the surfaces of your teeth and whiten your teeth by making them brighter and shine.

Toothpaste for Smokers
The smokers often find their teeth with stains, as a result of smoking tobacco. So it is specially designed for smoking persons. This toothpaste contains cleansing agents with slightly abrasive. This is made for smokers to look their teeth whiter.

Toothpaste for Children
The children toothpaste is either contains less fluoride or without fluoride, this is because excessive ingesting of fluoride which is containing in toothpaste leads to health risks in children. And additionally these children toothpastes have been flavored in candy tastes.

Standard Toothpaste:
This toothpaste is normal, which is useful for normal people, as it contains very common ingredients. These will work better for normal people but not for the specialized ones as it is not specialized in this area.

So choose toothpaste according to your use, as it will work in a better way according to your situation.

What are the Different Types of Dental Lasers Used?

There are various types of dental lasers used in dentistry. The FDA (Food and Drug Administration) has been approved for variety of soft and hard tissue lasers which is for use in the dental treatment of children as well as adults, because the dental lasers are boasts unique absorption characteristics, that are used to perform a specific dental procedures.

The Soft Tissue Lasers:
This tissue boasts a wavelength which is highly absorbed by hemoglobin and water for making them more effective for the soft tissue management. The most commonly used soft tissue lasers are diode lasers and Nd:YAG, that can be used as component of periodontal treatments, which has the ability to activate the re-growth of tissues by killing bacteria. Compared to fiber optic method the carbon-dioxide laser removes the tissue faster. It also minimizes the damage to the surrounding tissue.

The Hard Tissue Lasers:
This will also have the wavelength that is highly absorb-able by water and hydroxypatite that making them more effective for the purpose of cutting through tooth structure. These lasers include Erbium chromium YSGG and Erbium YAG.

The various types of dental lasers as follows:

Low Level Lasers:
These low level lasers are less known, they are very less expensive and smaller. These are sometimes referred to as soft lasers which will perform the therapy, the therapy performed by this are known as low level laser therapy. This will regenerate the tissues and also improves the blood circulation.

The Carbon-dioxide Laser: This can be used to remove the small tumors and to perform the gingivectomy. This will not require local anesthesia. It is a blood less procedures and will pose no discomfort to the patient.

The Erbium:
The erbium laser is used to alter the pigmentation in the gingival tissues, by providing the patients with the pink gums. This is commonly used to prepare the patient for the purpose of cavity filling. The potential of replacing the drill is possessed by YAG laser.

The Diode Laser:
This laser has been in effective for endodontic treatment and for oral surgery, which is used to correct the aesthetic flaws and to treat oral cavity diseases. It is introduced in 1990’s and it is used to soft tissue.

The Nd:
The YAG is used in tissue retraction, oral surgery and endodontics. This is also does not require anesthesia. This is used for the procedures like the gingival pockets, then the dentist will insert the fiber between the tooth and gingival to stimulate and sterilize the tissue, by causing the gingival to adhere to your neck.
