When renovating a house or building a passive or low energy house, it is not only important that it is well insulated but also that it meets the building standards for air tightness. Airtight construction means that when building a house, the occurrence of drafts and other unwanted air flows are taken into account as much as possible. By sealing all joints, cracks and pipe connections as much as possible with a suitable filler, tape or foil during the construction process, you immediately make a good start when making a home airtight.
In practice, the air tightness is often tested by applying the ‘blower through’ test. A fan is placed in the door hole with which first an overpressure and then an underpressure is created. The pressure difference is measured with the aid of a pressure gauge and the ‘N50 value’ is finally determined on the basis of a calculation. The lower this value is, the more energy efficient the home is. In a passive house (very energy efficient) this value is less than 0.6.
Places that are sensitive to air leaks
A lot of research has been done into the airtightness of houses. It has been established that many draft problems are caused at the roof, in transit in the floor and in places where windows and doors join the wall. Since these places are closely connected to insulation, it goes without saying that airtight insulation is the solution here:
Roof insulation and air-tightness
The roof of the house is a place where you can save a lot of energy (up to 25%). This can be achieved by providing the roof with insulating material, such as glass or rock wool. This is the moment to pay the necessary attention to an airtight finish.
See if you can fill it with PUR then cut the foam as much as possible. After applying the insulation material, it is very important to finish the layer airtight with a good polyethylene film or so-called climate film. All seams and cracks must be taped, even near the walls. This way you create an air-tight and vapor-barrier layer that benefits the airtightness of the house.
Usually most air leaks occur at openings in the floor that serve as a passage for the piping. You can think of forwards for the water or gas pipeline and holes that are installed for sewer pipes or other drain pipes. This often leads to drafts from the crawl space, which has a negative effect on the overall airtightness of the house. These draft holes for passages are usually relatively easy to seal with PUR foam.
There are two ways to moderate the temperature of a house compared to seasonal swings in hot and cold weather. The first and more primitive method is to take advantage of thermal mass. This means using thick walls to absorb variations in temperature in order to balance an interior temperature that is warmer at night and cooler in the day. While this is still effective, it is more expensive to build houses with heavy walls.
The modern solution is to use fiberglass insulation. A home can be build using the lightest materials and yet stay warm or cool with much greater efficiency than homes in the past. This is largely due to increased use and sophistication of insulation to control all areas where heat transfer can occur. While it costs more money to improve the insulating properties of a home, it is a one-time cost. Electricity for the air conditioner is an ongoing cost.
Most insulation is in the walls, and older homes have adequate protection. Since glass fibers do not decay, they should not need replacing for the lifetime of the home. It is still possible to add an extra layer of fiberglass or else add a mat layer to the inside wall to provide one more barrier to the outdoors. Upgrades like this are often cheaper than changing the air conditioner and accrue whenever a new unit is purchased.
Of course, there are many cracks and surfaces that are not protected. One might be the ducts the hot and cold air pass through. These passages are usually located under the house and benefit from the moderating annual temperature of the earth, but sometimes an HVAC expert will recommend changing or improving insulation in the ducts. Since cold air might contain condensed moisture, replacement might be a health consideration.
Most unavoidable heat transfers occur through windows. This is unfortunate, since windows provide sunlight as well as access points for fire fighters. The problem can be mitigated by adding an insulating layer to the inside or outside of the house. This might be a piece of layered plastic used in greenhouses. A more attractive solution is to purchased double pane or layered windows.
Many services offer to replace old windows with new ones that are as practical as the old but contain an ultralight layer that acts as a thermal barrier. This type of insulation is high-tech, and it permanently increases the value of a home. Many newer houses employ these energy-saving innovations even while they are manufactured with lighter materials and more sparse skeletons. Your house could reduce its electric bill by a quarter or more with better insulation.
Advancement in technology has facilitated the pattern of life. One of the many innovations as a direct result of modern development is that of an insulation system. And the best part is, this system is helpful in housing, residential, commercial schemes as well as other business areas. When you look for good energy-saving options, you are going to think about proper insulation.
Keeping your internal air quality good is one thing you should look into as this concerns your health and the health of your family. A good insulation system protects the air from infiltration of mold, bacteria, and other allergens cause allergies and make people and pets sick. When your insulation unit runs well and puts out healthy air, everyone at home stays healthy throughout the hot season. The presence of moisture sees a reduction through regular insulation system. The insulation works with the other installations in the house and provides cover and create a shield on wall and ducts to prevent moisture buildup.
Get ready for the summers and save as much as 30% on energy costs. An insulation unit that is well-maintained uses less energy. To reduce your energy bills give it regular service. This way you can save money on repair and maintenance. The experts will point out the parts that need replacement or repair when they come out to service your insulation system. Adding an electronic thermostat will also help you get savings on bills.
The insulation covers your walls, housing structure, including the roof sealing. A robust insulation plan not only given you better ventilation but it will keep your house cool in summer and will preserve the heating during the cold winters. The energy you waste by using heat appliances during the cold, or the airconditioners in summers can bring a significant increase on your energy bills that you can save by using insulation and bring down your electrical bill. A house with proper insulation system also shoots the price of your home because such houses are the modern need of the average societies.
If you want to add insulation to an existing home or you are having a new construction where you want the insulation you can look out for the local contractors near you who hold the expertise for all insulation installation and maintenance. Around half of the heat in your house can escape if you do not have proper insulation, so it is a good idea to invest in this system to improve your air quality and stop any air leakages that escalates your energy costs in running the house.
Whether you need insulation for replacement purpose in an existing home or you require it for a new home construction — and whether you need it installed in your home’s basement, attic, or walls — you will want to hire only the best insulation company who are also experts in what they do. For you to find the best contractor for the job, below are some top qualities to look for before hiring them:
– A good reputation
You don’t want to hire a quack for the installation job, what you need is a contractor who you are sure will deliver on what they promise, which is high-quality work. There are a couple of ways to find out if a company has good reputation or not. First, prepare a list with names of insulation companies in your area. Then go online and see how they have been rated on the Better Business Bureau’s website. Narrow down the list based on the ratings each of the company has. Afterwards, check out the professional accreditations of the companies you are remaining with on your list and ask family or friends who have used their services before on how they were.
– Knowledge and experience
Apart from being an integral part of your home’s internal structure, insulation is also necessary in keeping the temperature inside cool in the summer and warm during winter. With that said, you will only want knowledgeable and experienced contractors to do any type of insulation work in your home. One way to find out a contractor’s level of knowledge and experience is to visit their website and find out how long they have been doing this. Also, do not forget to go through prior customers’ reviews as they will tell you more about the company than the company itself will.
– License and insurance
Never hire a contractor who is not licensed or insured for residential insulation work. This is against the law in most states, and it is also for your safety. In case the contractor incurs an injury while doing a job on your property and he or she is not licensed or insured, you will be held liable. Ensure that they are insured for your peace of mind incase of an accident.
– Exceptional customer service
It doesn’t matter the industry, these days, high-quality customer service is vital for the success of any company. Why spend a lot of your hard earned money only to end up poorly treated by a service provider? This is something you do not have to encounter. A good company will never allow its staff to act in a rude manner or do poor work. Only hire an insulation company with exceptional customer service.
