Home insulators manage the temperature inside the house. Effective temperature control will reduce the use of cooling devices like air conditioners and electric fans in summer or heating devices during winter which is important to reduce utility bills.
The more effective your insulator is, the less electricity you consume.
Insulating materials can enhance your home design.
Importance of Knowing the R-value of Materials
R-value is the ability of an insulating material to resist heat flow or simply called thermal resistance. Calculating the R-value of a type of insulator means adding all the R-values of the materials you use.
Reduce Heat and Add Beauty
Sometimes a combination of different materials is not only more effective in reducing the heat in the house but also adds to the overall beauty of the façade. Modern materials are now less bulky, more durable and at the same time more appealing to the eyes.
Choose your Home Insulators
A highly durable material with a high R-value ranging from 11-38. This insulation is usually found in walls, floors, air ducts and pipes. Fiberglass is fibrous and consists of sand and recycled glass making it non-combustible. It can either be in blanket form or loose form because it can be formed in batts or rolls of various sizes and thickness. This material does not absorb water or any type of moisture so it is able to retain its R-value.
Conventional materials like wool, cellulose(newspaper) are cheap insulators but are not water-resistant but are still commonly used because these are relatively cheap. Although chemicals may be added to make it resist moisture or fire, it is not as effective as fiberglass. When these materials get wet, their R-values go down meaning they are rendered useless. Both conventional materials and fiberglass are considered the cheapest among other insulators.
A kind of plastic insulating material that has an R-value of 5-8. It comes in liquid or rigid foam board. You may use panels to cover your walls or if you want to retain your home design, then you should use the spray or liquid form.
A clear thermoplastic material that can come in foam boards, concrete block or loose form. The loose form looks like beads and is used to fill in irregular spaces. However, the beads can come out even in small holes making it difficult to control. This material can resist moisture, moulds and mildew, rot, corrosion and in combination with an adequate drainage system, probably is the most cost-efficient solution in the long run.
A plastic that comes in liquid form and it's the material of choice for most of seashore home builders, often used on roofs, walls, ceilings and basements. It is sprayed on any material and it becomes fairly rigid yet soft to touch. This insulator can resist moisture making it retain its high R-value.
The last 3 materials discussed cost higher than fiberglass and other conventional insulators but they can be sprayed on any part of your home. Although they cost more, they can become more cost-efficient in the long run because they can last for years.
