How you install crawl space insulation depends on whether or not your space is ventilated or unventilated. If your crawl space is unventilated, then it will be easier to insulate. You only have to apply crawl space insulation on the foundation’s walls rather than the sub-floor. You will need Batt insulation with an R-factor of 10. Cut lengths of the insulation material long enough to extend from the mudsill (the board on top of the wall) all the way down to around two feet onto the floor. Secure the material with 2 by 2 cleats, then drive nails through the cleats into the mudsill. Hold the insulation along the bottom of the wall in place by placing some bricks or a length of 2 by 4 lumber on top of it. Also, cut small pieces of insulation to insulate the joists.

Installing crawl space insulation is harder if your crawl space is ventilated. First you have to prepare the space by ensuring that all holes in the floor above are sealed to stop air from blowing into the house. Apart from applying crawl space insulation to the walls, you also need to insulate between the floor joists using rolled fiberglass. Ensure that the insulation is firmly in place by using mechanical fasteners.

When installing crawl space insulation, you should also keep moisture control measures in mind. Face the insulation with a vapor barrier. Although the vapor barrier is usually placed upward, in areas of the country with mild winters and hot summers the vapor barrier should face downward. You also need to install moisture retarding material (such as polyethylene vapor retarder) on the dirt floor and make sure it is carefully taped and sealed. Cover it with a fine layer of sand or concrete to prevent it from damage, but avoid materials that could pierce it such as crushed gravel. You also need to place crawl space insulation on the air ducts. Don’t forget to close the vents after installing insulation to ensure that the space stays dry. And take pest control measures as the insulation may be damaged by rats and other vermin.

You may also want to consider friction-fit Batts if you are installing crawl space insulation in a ventilated area. This type of insulation has metal rods as thick as the metal used in hangers (called ‘lightning rods’) fixed inside the fiberglass. These lightning rods stick out a couple of inches longer than the inside joist spaces to hold the insulation up inside the floor joists. Using friction-fit Batts makes it easier to place crawl space insulation on a floor from below.

Adding vents to the crawl space is not something that is recommended.  It is advised that vents in the crawl space actually pull air from the outside, creating a home that is not energy efficient.  This allows you’re heating and air-conditioning bills to sky rocket and it draws moisture into the home, which is something you’re trying to prevent.

Most people now are putting vent covers on their old vents.  These vent covers are best if made out of a hardy plastic as to prevent any rust from starting.  After vent covers are put on old vents, an entire encapsulation process is usually started.

If you are thinking about crawl space vents, try doing an entire encapsulation instead.  That means that you will provide an exit for moisture in a different way than adding vents.  By adding vapour seal barriers you can actually keep mould, mildew and decay away.  Putting in a whole moisture protection system will also ensure that pests like, termites and carpenter ants stay away.

The first thing you will want to do is put in efficient grading and drainage to your crawl space area.  This will keep dirt and rain water away.  You can then isolate the crawl space from moisture by lining the whole space with thick and strong vapour barriers.  These barriers should also be puncture resistant and multilayered with 20 mil poly sheets.

When the plastic barriers are in place you can use mastic tape to seal any seams and caulk around seal openings in the walls.  Strips and caps can be added to ensure a tight fit.  Putting a conditioner in the crawl space to blow air from the above into the space or adding a dehumidifier, will keep the air quality and humidity where it should be.

Always make sure that if you have crawl space vents, that you never leave them open and use fans to blow air from the outside into the crawl space, and that you don’t use fans to blow air out of the crawl space.  You will also want to make sure that you don’t install a liner on the concert floor without removing all organic debris and insulation from crawl space floor first.

Properly setting up your crawl space for success, means that you have researched your project and have received expert advice from the source you are buying the materials from.  Don’t skimp out on important details that will only hurt you down the road.  If you do the project right the first time, you won’t have to repeat it in a few years or have issues arise that you thought you would never have to face.

There are several ways to insulate crawl space areas.  The first is by using liquid foam insulation.  And these products are not all the same so it is important to read about them and figure out which one would work best for your space.  These liquid insulators are great because they are damp resistant and moisture retardant.  A product called icynerefoam is a popular one.

While some people will swear by liquid insulators, others prefer the results of cellular glass.  They feel that this product is waterproof and impervious to water vapour and that mice and rats to do like the hard texture.

Deciding on what kind of product will work to insulate craw space spots, it is important to look at a few areas of concern first.  You will want to write down some information about your house that you can take with you to the store where you will be purchasing your insulation.  There are some topics to think about before you head in to buy anything.

The first thing you will want to determine is the climate of your area, many climates will determine what kind of products you can use.  The next thing to consider is your geological location and what direction your house is facing.  Is your home facing afternoon heat or morning heat from the sun?  You will also want to assess where the drainage is around your home, and what your local builders code permit. Builder’s permits vary from town to town, so it is important to keep current and up-to-date on policies and procedures when doing any kind of construction to your home.

The age of your home is also important and if your crawl space is vented it is also an important factor to consider.  In the past many crawl spaces had vents to try and pull moisture out of them.  But new houses use different strategies and it is crucial to know what kind of system if any that your house has.

These days’ people are choosing environment friendly products to insulate crawl space areas.  They are picking products without harmful chemicals that are known to hurt the ozone layer.  They are also picking products that are made of natural, organic and recycled materials.  When products are made in an environmental way and we use them in your house, it can only allow us to contribute to a healthy home and environment.

Always check with a professional when insulating your crawl space.  You will want to make sure that you are using the right products and doing the project properly before wasting time doing it wrong.

Crawl spaces are spaces in the basement that are too low to stand up, but not properly finished so you can’t store anything in it.  Because there is no circulation in the small room typesetting, the warm air from the surrounding basement and the crawlspace do not know how to mix properly.  Builders are required to put vents into crawlspaces to ensure proper ventilation, but many home owners are discovering that vents are not keeping problems away.  The vents are just blowing air around to try and circulate, however because the air in the crawlspace is not moving at all, it doesn’t work.

The crawl space is very prone to retaining moisture and attracting mold.  That is why creating an opportunity to do a crawl space encapsulation makes sense! And it is not only mold that you have to worry about, it’s also; dust mites, carpenter ants, vermin and termites and in some cases even wild life.  These types of things are attracted to mold and mildew and decay…the very things that may be lurking in a crawl space.

To fully encapsulate the crawl space there are specific things that can be done.  The first thing is put in proper grading and drainage of dirt, this keeps rain water away from the crawl space area.

The next thing that you will want to do is to isolate the crawl space from attracting moisture.  You can do this by lining the whole crawl space with thick and strong vapor barrier that is also puncture resistant.  The layer should be multi-layered and at least a 20 mil poly sheet.  You can also try using mastic tape to seal the seams and caulk to seal openings in the walls.  Strips and caps will give your encapsulation a professional touch and will allow you to monitor for ants and termites.

The last thing you will want to do for your crawl space is to condition it.  That means that you have a conditioner to blow air from above into the space.  This allows for proper circulation and ventilation creating a healthy air flow through-out the home.  You can also try a dehumidifier in the crawl space to prevent moisture from being created.

When you have finished your crawl space encapsulation, you will find that you can actually store things down there.  Items that were once in your way can now be tucked away neatly in a safe and secure spot.  The new crawl space will allow for healthier air and help to cut energy costs by allowing warm air to filter back through-out the house instead of getting stuck in the crawl space.

Many people do not think of mold building up in the crawl space.  They think about it in the bathroom around the grout in the shower, and they also think about it when they see a water leak somewhere in the house, but many forget about other places in the home that may be prone to developing mold and mildew.

The crawl space attracts mold and mildew and decay, because of the air temperature difference between the crawl space and the rest of the house.  Not only is the temperature different but there is also no proper ventilation that keeps the air moving accordingly.  Home builders are required to put vents in the crawl space but more often than not, the vents do not do a good job.  They do not do a great job because unlike the upstairs of the house, the crawl space does not have the same kind of flowing air you would expect in other areas of the house, so while a vent keeps moisture out of the bathroom, it does not do very well in the crawl space.

Many people decide to put a crawl space vapor barrier in the space to get rid of or prevent trouble from arising.  A vapor barrier keeps everything flowing properly and maintains a proper amount of air quality and air flow as to prevent any moisture from accumulating.  There are a few ways to go about putting in a barrier, and some work better than others.

The best way to put one is to isolate the crawl space using a thick and strong vapor barrier.  This will consist of multi-layered 20 mil poly sheets.  It should also be puncture resistant so that holes are not accidentally put into the plastic and defeat the entire purpose of the barrier and hard work!

You can use mastic tape to seal any seams in the walls and caulk to seal any openings in the walls and structures.  For an even more professional look, you can try adding strips and caps to keep an eye on any termite and ant issues.

Many people install the wrong kind of vapor barriers.  They might install a vapor barrier or a rigid foam insulation board on the ceiling of the crawl space.  Or they might close vents and leave the ground uncovered.  Some people even seal the ground with vapor barrier but leave the vents open.  It is also not advised to use fans to blow outside air into the crawl space or use fans to blow air out of the crawl space.  For the ultimate crawl space vapor barrier it is recommended that you follow proper instructions.

Crawl space ventilation is a sure way to beat all the trouble that can arise down there.  The first thing you will want to do is inspect your crawl space for any damage.  If mould and mildew has already formed you might have some real trouble on your hands.  It could also be home to termites, carpenter ants, dust mites, vermin and wild life.  So you might want to inspect the crawl space for any sign of these pesky things.  If you do have them, you will have to treat those issues first before you begin your ventilation process.  Even if your crawl space shoes no sign of trouble or mould and mildew, it’s important to begin the ventilation process to ensure that you’re crawl space does not become troublesome in the future.

There is a right way to ventilate your crawl space and a wrong way.  First I will discuss the wrong way to do it.  If done wrong it can cause issues for your space even though you spent lots of time trying to prevent it!  You don’t want to install vapour barriers or rigid foam insulation boards on the ceiling of your crawl space.  You also do not want to close the vents and leave the ground uncovered.  You might also not want to seal the ground with a vapour barrier and leave the vents open.  It is also not a great idea to use any fans to blow air into or out of the crawl space.

Now for what you should do when trying to achieve crawl space ventilation.  The first thing you should do is provide proper grading and drainage of dirt to keep rain water away from your crawl space.  Then you should isolate the crawl space from moisture by lining the whole space with thick and durable vapour barriers.  It should be strong and puncture resistant.  The plastic should be multilayered and 20 mil poly sheets.  You can also use mastic tape to seal seams and caulk around any seal openings in the walls.  Strips and caps will give your crawl space a professional feature.  This will allow you to check for any ants or termites.

To keep your crawl space ventilation in perfect condition, you should by a conditioner to blow air from the above levels into the crawl space or at least provide a dehumidifier in the crawl space to prevent any moisture from becoming entrapped.

When your crawl space in well ventilated and is working properly, you will not have an issue with mould or mildew.  You will also give your family a healthy house to breath in and save money on energy by not wasting any heat!

Okay, so now that you’re convinced, what materials should you buy for crawl space insulation? There are many types of insulation but the most popular for crawl space insulation are fiberglass and foam. This type of insulation uses different thicknesses of fiberglass backed with moisture-resistant paper. You should buy your fiberglass insulation in batts (pre-cut panels of insulation) since these are the cheapest wall insulation material. Batts are available in sizes cut to fit regular wall frames, which are usually spaced twelve inches, sixteen inches or twenty-four inches.  But you can also buy insulation in continuous rolls if you need to cut it to fit.

Fiberglass batts are also available with or without facing. The material used in faced batts acts as a vapor retarder to prevent insulation from becoming damp. Which one you use depends on which area you are insulating. Crawl space insulation of heated spaces or those with ducts or water pipes that are not insulated should use unfaced batts. On the other hand, for under-floor crawl space insulation, you should use faced batts.

You can also use rigid foam insulation for crawlspace insulation. Rigid insulation is produced either in boards or as molded pipe coverings. The boards may also be faced with reflective foil to reduce heat flow when they are installed next to an air space. Rigid foam insulation is best used for crawl space insulation of interior walls.

You can also apply foam insulation by spraying it into place. It can be sprayed into small nooks and crannies and will expand to fit the space as it dries. This type of insulation is produced in two forms: open-cell and closed-cell. Open-cell foam allows water vapor to move through the material with less difficulty. On the other hand, some closed-cell foams can provide a greater R-value. R-value is a way of rating insulation by its resistance to heat flow. The higher the R-value, the more effective the material is as an insulator.

So how do you decide which materials to use for your crawl space insulation?  You should consider the following factors: climate and kind of crawlspace. The climate of the area that you’re living in will determine the R-value of the insulation you will buy. But it is always recommended that you get the highest R-value that you can afford. You also need to determine if your crawl space is ventilated or unventilated.

Crawl space insulation is probably one of the best home improvement investments you will ever make. So it is probably better to consult with a professional first, even if you intend to do the work yourself. This will enable you to avoid costly mistakes that you may have to correct later.

There are two types of crawl space insulation. These are the vented and unvented crawl insulations. The terms are simply taken from the types of crawl spaces available. Spaces open to the outside is called vented and spaces part in the basement is also named as invented.

Other advantage in installing crawl space insulation is to block unexpected burst of pipes, and also to protect from freezing and other related extreme temperatures. Crawl space insulation is effective in reducing home mishap expense and conserve energy cost. Crawl space insulation is also proven itself in providing comfort by putting off cold floors during winter and hot floors during summer season.

Installing crawl space insulation varies from various crawl spaces. Vented crawl space insulation has the specific steps far different with unvented crawl space insulation.

There are four easy steps in installing vented crawl spaces.

•        Before putting your insulation, it is wise to cover the walls and ceilings with pieces of six-mil plastic film. Make sure that the film overlaps by about 12 inches. It must extend inches up to the wall. It is deemed necessary to maximize the potential of your vented crawl space insulation.

•        After you’ve covered the ground with the six-mil plastic film, start taping the film. You may use other weight to hold the film on other ends as you tape some parts.

•        When done taping the film, you can now put in the crawl space insulation batts into the shaft or girder with the vapor retarder. Make sure this vapor retarder is facing against the sub-floor. Double check if the insulation mounts securely allowing no air space at all among the insulation and the flooring.

•        Lastly, tack the insulation flanges tightly to the sides and or even bottoms

For the unvented crawl space insulation, there are five different steps in installing the insulation for unvented crawl spaces. Of course, following the first two steps for the vented crawl spaces, you can now proceed to the next step.

•        Prepare the pieces of unfaced insulation. Measure and cut them. When you have these pieces ready, position them against the header joists. Make sure to stuff all the spaces surrounding sub-floor, floor joists and sill.

•        Next, set up leash of standard bats to the sill by furring strips to pin the insulation to the periphery of the sill plate. The padding or filling is long enough to slump the wall then must extend two feet to the space.

•        Third step is to fix the insulation close possible to the wall.

•        Arrange the insulation blanket against the base of the sub-floor then nail it completely to the stringer joist.

•        Ensure that all parts and portion of insulation are compactly clout together.
