Rigid Foam insulation is often used for unfinished buildings and everyday products including installing attic insulation. The beads are shaped under extreme heat and pressure to custom fit. There are three types I will discuss each one and their uses. I will also discuss precautions to take with this insulation. Before long you will have a better knowledge when installing attic insulation

The first is polystyrene. This type of insulation uses deep heat and pressure to mold into shape. It is best used in walls and installing attic insulation. Although it is more expensive than the other two its characteristics makes it a lot stronger and more durable than the others.

The second is polystyrene It to is shaped under extreme heat and pressure. It is more expensive than polystyrene, but because of its consistency, strength and higher resistance to moisture it works better when installing attic insulation and in walls.

The third is polyisocyanurate and polyiso foam boards this product has varies strengths allowing it to maintain shape and stability. It can be used in extreme high, low temps effectively, making it ideal for installing attic insulation. When used with aluminum foil facings makes a perfect moisture barrier.

There are some things that you need to know before using rigid foam insulation. First we will discuss flame retarder. This product takes a lot to ignite but once it does it will burn steady. It will also smolder for some time. Safety regulations require you to use flame resistant material like panel, dry wall, or gypsum wall board over the insulation. It also deteriorates in direct sunlight so if you are installing attic insulation it needs protected with acrylic silicone, rubberized paint asphalt, roofing felt, or tar.

Bugs and sunlight damage is another concern with rigid foam board. If using this product on floors or basement its best to use insecticide treated product. Some areas require the vicinity around the foundation to be treated. Another way to prevent bugs is to apply on the inside walls not outside. If you do install on interior wall you might need a vapor diffusion retarder.

Rigid foam insulation soaks in and traps moisture. This could easily cause mold and wood damage. To prevent this you should use a vapor diffusion retarder especially when installing attic insulation.

When installing attic insulation, rigid board insulation can be an effective, if done properly. If you decide to install insulation yourself be sure that you know how to install this product, safety precautions and building code regulations.

Many have heard about spray on foam insulation but only a few knows t the specifics. I will explain what it is and how it works. There are different costs and benefits for this product, which is especially effective to use when installing attic installation.

Spray on foam insulation is a liquid insulation made from polyurethane or urethane with a foaming agent. It is easy to apply; you spray the foam into the area, wait until it dries then cut away the excess. Next you apply the thermal cup. There is no need to caulk, vapor barrier, or house wrap. Spray on foam insulation does it for you by producing an air tight seal.

This insulation has many uses some of these include: roofing, walls, ceilings, basements and when installing attic insulation. It has also been used in restaurant freezers, walk in coolers and storage facilities. It’s been used for boats and boat docks. Airlines use it to strengthen airplane wings.

It has many uses for instance; installing attic installation, ceilings, floors, walls and roofs. Restaurants use them in their walk-ins’ and freezers. Sailors use them on boats and boat docks. Some have even strengthened plane wings with the spray on foam insulation.

Spray on foam insulation is cost effect by reducing contracted man hours. it forms such an air tight seal the need for caulking, house wrap and vapor barriers are eliminated. Since you can apply it over old material the need to rip out the old is also eliminated.

Spray on foam insulation is made from a polyurethane or urethane base. This makes it is safe to use and environmental friendly. It also reduces the need for fossil fuel which helps reduce global warming.

The cost for insulation ranges from $1.25 to $2.25 a square foot. It depends on the thickness of the wall and type used. Fiberglass may be cheaper initially, but when you add the cost for removing old material and winterizing the cost evens out

Spray on foam insulation is used in homes, restaurants, boats and planes. It’s handy when working in small area, For instance installing attic insulation. It’s simple to apply and you don’t have a big mess afterwards. Most importantly benefits out weigh the cost of spray on foam liquid insulation.

Crawl space and attic insulation are essential when weatherizing your home. Without proper insulation air leakage will occur. This will make your heating and air work harder, less effectively. I will explain the best way to insulate both your attic and crawl space.

Before beginning crawl space insulation close foundation. Make sure all appliances in the crawl space have a powered combustion system before closing. Insulation should be taped at the seams and then fastened. After insulating, the house should be house wrapped or vapor barrier.

Once insulation attic insulation is complete, it’s suggested to add an air tight moisture barrier, for better moisture control. Once insulation is complete a good vent is needed. This will prevent roof damage.

Next insulate and secure the area. Some prefer fiberglass, others batt and blanket for crawl space insulation. Place insulation over the entire area, filling gaps. Use batts with a vapor barrier to cut and fit insulation around plumbing and electrical. Use foam or foam and fiberglass for band joints and air ducts. Use polyurethane foam for rim joist. Foam sheet or fiber glass should be used on foundation walls. Use insulation hangers 12-18″ apart to hold in place. Facing should face up unless you live in an area with mild winters and hot summers.

If you have a vented crawl space make sure appliances in it has a powered combustion system then close the vents, to prevent moisture buildup. When insulation be sure to tape the seams before you fasten them and either house wrap, vapor barrier afterwards.

The final step in crawl space insulation is to protect your home against moisture and bugs. The crawl space dirt floor should be covered in polyethylene and then facings on top. The facing seams should be taped to ensure a better seal. Finally apply a shield against termites between band joints and the masonry foundation. It is wise to leave a 3″ for termite inspection.

Once the attic insulation is up a tight moisture seal barrier should be applied across the studs. If holes are found in the barrier you can carefully patch these with duct tape. Once your insulation is complete you will need a good ventilation system to prevent damage to your roof.

Crawl space insulation and Attic insulation is very cost effective if done right. Not only will it save on fuel costs but will add to the value of your home.

When choosing insulation there are 4 groups to consider they are; loose fill, foam board, Spray on foam and batt and blanket. All has job they are better suited for. Each has good characteristics and bad, with some R factor higher than the others. I will explain the difference between them so you can decide which one suits you.

Spray foam is one type to consider when choosing insulation. The insulation comes in easy to use bottles. It’s sprayed into the area to be insulated. It expands as its sprayed filling all the cracks, giving a better coverage. The initial cost is more, but unlike the others you do not need to winterize later. You will find it in insulated attics and finished walls. It’s the best to use in tight enclosed places.

The loose fill is similar to spray foam because it to is blown into the area. There are two types Cellulose, fiberglass and rock wool. Like spray foam it is used in finished walls and insulated attics. Its R factor is 3 or 4 with cellulose having a 30% higher R factor.

The third to consider when choosing insulation is foam board. It’s made from fiberglass, polystyrene or polyurethane. This insulation is used in edges of concrete blocks, borders, insulated attics and basement walls. The R factor is a little higher than the other it’s R4-R8 per square inch.

When choosing insulation batt and blanket insulation should be considered. This insulation comes in either 8′ sheets or rolls. It’s made from fiberglass or rock wool. It is cheaper per inch. special precautions are needed when installing. This is generally used in unfinished products like walls and insulated attics.

One thing to consider when choosing insulation is flame resistant’s Fiberglass insulation, spray on foam, batt and blanket are flame resist. Cellulose and foam boards are not. In fact foam boards require flame resistant covering like panel or dry wall.

When choosing insulation flame resistance is an important consideration. Two of these are not flame resistant they are: foam board and cellulose.

The four groups batt and blanket, loose fill, Spray on foam and foam board. Each one insulates, but the loose fill and spray on foam covers the cracks and crevices better. Cellulose is a type of loose foam but it is not flame resistant. Foam board is also not flame resistant and requires covering. All are ecological friendly. Most can be found in insulated attics, walls and ceilings.

Expanding foam insulation is used for ceilings, walls, attics and basements. It’s also used around window seals, electrical boxes, outlets and other small, enclosed places. Sailors use it for docks and pilots to strengthen airplane wings. What is it, and how is it applied? I will give you details on this and the other 3 insulations types, in hopes to assist you when choosing insulation.

How is Expanding foam insulation applied? Contractors use special equipment to shoot either polyurethane or modified urethane liquid into the area. While drying it expands to fill every inch, once it’s dry, the excess is scraped off and a thermal barrier is applied

Next we will consider rigid board when we are choosing insulation. It’s made from fiberglass, polyurethane or polystyrene. It’s used in basement walls cathedral ceilings, flat roofs and building perimeters. Rigid board is not moisture or flame resistant. Bugs often burrow in this insulation. This product required to be covered by fire resistant paneling or dry wall. I wouldn’t consider rigid board when choosing insulation.

The third to consider when choosing insulation is loose fill. This insulation is made from fiberglass or cellulose. It is blown into the walls to make a blanket effect. This insulation is used in attics and walls of unfinished buildings. It’s treated to for fire and moisture protection.

Loose fill made from fiberglass or cellulose like Expanding foam insulation it’s blown into the walls to make a blanket effect. It is used in unfinished attics and walls.

When choosing insulation you should think about Batt and blanket. It’s made from fiberglass and rock wool. It’s installed between studs 16-24″ apart. It’s the cheapest, but proper installation is needed. After installing the house needs winterized further.

Expanding foam insulation has many uses from finished walls, ceilings, floors to boat docks to airplanes. Contractors especially like this insulation in tight enclosed places like electrical boxes, outlets, and window seals.

Expanding Foam insulation costs between $1.25 -$2.25 to install, but unlike the other, it doesn’t require extra work. It’s environmental friendly because it takes less energy to produce, does not hurt the ozone layer and reduces global warming gases. It improves air quality and reduces noise.

Reflective insulation is a form of thermal insulation that uses reflective material such as aluminium to block out the transfer of radiant heat. Radiant heat, for example from the sun, travels through space from hot to a cooler surface. In this case, most of the heat your home will be exposed to will be on the roof which is then transferred to the rest of the house.

For that reason, it is ideal to use reflective insulation on the roof and attic. Most energy transfer from home to environment and vice versa occurs through those spaces. Thermal insulation reduces the heat transfer from a building and its environment. When there is a difference in temperature between two bodies, heat flows naturally from the warmer body to the cooler one. To maintain a comfortable temperature within the home, we turn our heating systems on in the winter and use air conditioning during the summer.

Most of the energy we use in the home goes towards heating and cooling. Using reflective insulation for your roof and attic reduces this huge waste of energy by decreasing the heat transfer so you require less energy to either heat or cool your home.

Reflective insulation is an environmentally friendly method of thermal insulation. Correctly installed insulation reduces air gaps and seals the building better further reducing the amount of energy that is normally wasted in the home due to bad insulation. This in turn reduces the amount of electrical power we use thus reducing our bills.

There are various types of reflective insulation that are available through different retailers. You may insulate your roof and attic yourself but it is always better to have the professionals do it. They will conduct a thorough check of the roof, for example for damp areas that may give rise to problems with the insulation in the future.

When insulating your attic you have to think about what type of insulation you want to use, how much you need, how much it is going to cost and the most important, how good is the insulation and will it last? There are different types of insulation and most very easy to install.

If you want a long lasting and very effective insulation, foam insulation is one of the best, but it is harder to install and therefore it must be installed by a professional. Foam insulation is also a bit more expensive than the other methods because it offers the highest R value in insulation and is also the longest lasting method of insulation.

Foam insulation comes in two types. The first is open celled foam, foam that is less compressed and holds a lot of air bubbles, because of this it can be removed very simply removed. The second is closed cell foams, foam that is very dense and compressed and hardly holds any air at all, this foam is a lot harder and is higher in R value and can’t be removed easily.

Because of the difficulty of installation for this type of insulation it should be carried out by a professional, so that it is done properly. The foam must be mixed and then placed into a machine to be able to spray it into the holes and uneven spaces in the attic. The foam will spread through the holes and begin to expand and get harder. If sprayed evenly, there will be no gaps between the insulation and will last longer.

Make sure that you are fully protected if you are in the attic when the insulation is taking place. By having your face and body fully covered with the proper mask and clothes, you will be at less risk from any damage the foam may cause.
