5 common spray foam insulation mistakes to avoid

Many homeowners use spray foam insulation to seal off cavities in floors, walls, and ceilings to prevent air from moving in the house. Sometimes, they also fill up spaces around light fixtures and electric outlets. The primary reason is maintaining a constant temperature inside the house to avoid high energy bills. But this purpose is often defeated when people make mistakes while installing insulation. So, here are some common spray foam insulation mistakes to avoid:

1. Failing to do research on the type of insulation required
Most of the time, homeowners need to think about their insulation needs. They don’t invest enough time in understanding that various types of insulation are available, such as aluminum cladding, mineral wool insulation, and fiberglass pipe insulation. Each has advantages and uses, such as being more suited for soundproofing, while another is best for temperature maintenance. Hence, it is crucial to understand why insulation is required and, accordingly, pick a type that would be the best fit.

2. Applying foam too quickly
The efficiency of spray foam insulation is often affected when applied too quickly. Being hasty with the installation can usually leave a lot of spare areas of foam. This usually happens when the spray foam rig has a clogged hose or nozzle. As a result, the foam does not thoroughly cover specific areas. The uneven coating will defeat the purpose of installing the spray foam. A thick and even application is necessary for the insulation to work properly.

3. Installing insulation improperly
A homeowner may stretch out their budget and purchase the best quality of insulation. Yet, it will not work efficiently if the installation is not proper and correct. Whatever the insulation type or quality, it is crucial to follow the installation instructions specified by the manufacturer. Also, unless one is sufficiently skilled in installing insulation, it is best to hire professionals. Insulation contractors know their job well and will ensure the installation is done properly to last longer.

4. Spraying too much foam
Another common spray foam insulation mistake is over-spraying it. The foam layer can pack down the foam material when it is too thick. This can be a problem with certain types of spray foam, such as open-cell ones and closed-cell ones. This ends up expanding a bit after each application. So, waiting a couple of minutes after applying a layer is helpful so the foam can expand to its full size. This will avoid the mistake of over-spraying.

5. Failing to address an odor
It is normal for spray foam to have an odor while installed. However, it is cause for concern if the odor lasts long after the insulation process is done. This can be quite harmful for those working or living in the space where the insulation has been installed. To avoid this, the odor must be handled right at the time of applying the foam insulation. For this, many contractors often use large air exchange units. These are usually kept in the area where the spray foam insulation is being installed.

Here’s how you can get your allergies detected

How many times have allergies caused you to sneeze every time you take a ride in the open air? Or rashes on coming in contact with a plant? Or swelling as a result of a peanut allergy? Sneezing, running noses, watery eyes, rashes, swelling all these reactions due to allergies can be quite distressing. Allergies are more common and can be caused by various things. The cause of allergies is still unknown, it could be genetic or just a singular development. However, they can be easily detected by just visiting your doctor and undergoing some tests. Read on to know more about what are allergies and how to detect them. What are allergies? The immune system is designed to fight any entrant in the body that it recognizes as foreign. However, at times, the immune system becomes over vigilant and starts fighting foreign entrants that are not harmful. Substances that cause the immune system to react this way are called “allergens”, and when you display symptoms of these interactions, you are diagnosed “allergic” to the substance. Allergens can include plants, grass, pollen, dust, food, animal dander among others. While symptoms like running nose, sneezing, watery eyes, rashes, itching, and others, are all attributed to allergic reactions.

5 frequently asked questions about Alzheimer’s disease

A common form of dementia, Alzheimer’s disease is a debilitating and progressive disease that affects the brain and motor functions of the body. The disease progresses through stages. It begins to affect the regions of the brain that control language, thought, and memory. In most of the cases, it begins with a slight memory loss. In the final stages, Alzheimer’s disease leads to the loss of various abilities including motor skills, speech, and independent movement. Here are a few frequently asked questions about Alzheimer’s. What are the causes? Alzheimer’s disease does not have any definite cause. Research has been unable to conclude whether Alzheimer’s is developed by one cause or multiple ones. The exact cause of the ailment is not yet known. However, there are multiple factors that may increase the risk of Alzheimer’s disease. One of the major causes is ageism. Also, a family history of Alzheimer’s is another major risk. This may lead to the inheritance of genes that cause this disease. Some other possible risk factors that can cause Alzheimer’s include high blood pressure, cardiovascular diseases, and high cholesterol. What are the symptoms? In most cases, the first warning sign of Alzheimer’s disease is a loss of cognitive ability.

Four important steps in anemia management

Hemoglobin is a protein molecule in the red blood cells responsible for carrying oxygen throughout the body. Its richness in iron gives blood its red color. Anemia is a condition where a person has low hemoglobin or red blood cell count. From an underlying disease to nutrient deficiencies, there are a lot of factors that contribute to the onset of this condition. There are many forms of anemia. Some of them include: Iron deficiency anemia -This is caused due to low iron levels in the blood. Most common causes of this type of anemia are heavy menstruation or internal bleeding. Vitamin deficiency anemia – This type of anemia is caused by the deficiency of vitamin C, B-12 or folate Aplastic anemia – Damaged stem cells in the bone marrow fail to produce enough red blood cells, leading to aplastic anemia. Sickle cell anemia – This is a condition characterized by the development of abnormal crescent-shaped red blood cells. Hemolytic anemia – This is a blood disorder caused due to premature death of red blood cells. Thalassemia – This is caused due to low amounts of hemoglobin in the blood. The blood disorders vary in duration and severity. Prompt diagnosis, and treatment are important because anemia could also be due to an underlying condition.
