Spray Foam Roof Insulation

In case you are considering insulation of your roof with spray foam it will be good to understand what is insulation and what is spray foam.

For instance let’s say you have wood shingles on your roof. With passage of time, shingles develop minute cracks that you may not be able to see at times. Outside air enters you room thru these cracks and changes the temperature of your room. If the cracks are filled with some material, the outside air has no chance of entering your room to affect its temperature. One of the materials used for filing these cracks is foam.

But, what is spray foam? Spray polyurethane foam, or SPF, is simply insulating foam plastic. It is sprayed in liquid form, but on getting cured, expands many times its original size.


Two varieties of the product are available: High Density and Low Density. Now, you have to decide which one to use for insulating your roof.
It’s good to go for the high density. The high-density insulation gives you more value for your money as it has a higher R-value per inch. But, note that higher density foam is liable to get rigid. It becomes very stiff on getting fully cured.

DIY kits are available in case you like to carry the insulation on your own, but it is highly desirable getting it done from a professional, more so if it is going to be high density foam which expands and needs to be handled with caution lest it causes any damage.

One big advantage of using spray foam for insulating roof is that it is not prone to getting damaged by moisture, thus acting like an insulator as well a barrier for moisture. That means it traps more heat, as it has no escape route. The result--your power bills are reduced. On the negative side, it traps humidity also, and humidity can make you feel miserable.

Please understand that spray foam is an excellent insulating material but don’t think it can replace your ceiling. You need to have a ceiling that needs insulation with foam.

In case you decide to have the application of foam as a DIY project, here’s the most important precaution that you must not ignore. Before you start spraying, make sure there is no trapped moisture. So, the best part of the year for undertaking this project will be in summers when it hasn’t rained for a long time. That makes it certain there is no moisture entrapped in your ceiling.

Attic Insulation - Crucial Home Heating System

Insulation of your attic offers the easiest and economical way of reducing your heating bills. Of course, there are many options these days and one often hears of new energy-efficient furnaces. But, for any reason if you are not planning to replace your heating system or find the eco-friendly appliances a bit too expensive, insulation makes a very good choice.

As we all know that air on getting heated rises above the floor towards the ceiling, unless there is some preventive arrangement at the top, the hot air would leak out from there. It’s not hot air that is leaking out, but the money you spend on heating air that is continuously being thrown out of the room. So, providing insulation retains the hot air within the room, thereby reducing the load on your heating arrangement and hence saving your money. There are different materials and ways of providing insulation, but three of the more popular ones are mentioned here.

Fiberglass Batt Insulation

Most of the householders associate fiberglass batts with insulation. These are long strips in pink or yellow color. Batt insulation is quite convenient to install and one can have it with different “R” values. Further, you may have it with or without vapor barrier backings. Ideally, it’s suitable for places that have no wires or pipes or such protrusions, but people prefer to use it for homes for the sheer convenience of installation. To accommodate the said protrusions, you necessarily have to make holes or slits around them and that makes the insulation far from perfect. Such improper installations fail to provide the desired level of insulation and you may continue to have leakages of hot air.

Cellulose Blown Insulation

Though cheaper than fiberglass batts, cellulose insulation would generally call for the services of a professional installer, thereby adding to the final cost. Cellulose insulation is a loose fill material that is uniformly applied to the attic, leaving no gaps in its coating. A professionally executed job ensures that the insulation is applied uniformly and there are no holes for hot air to escape the attic. This type of insulation is classified as “green”, being made from recycled paper, and therefore finds favor with people who are conscious of environments. Though treated for retarding fires, it is prone to be infested by pests and mold. So, you’ll need to check on that aspect.

Spray Foam Insulation

Not so long ago, this kind of insulation was exclusively meant for commercial applications, but for quite sometime now it is also being used for domestic applications. The unique characteristic of this material is that it expands many times of its original size, thus getting squeezed into every nook and corner to provide complete insulation. Spray foam has high R-values and gives draft free insulation. At times too good insulation that it provides may cause overheating of your shingles at the underside of your ceiling. The insulation must be entrusted to professionals who have the special tools and skills to ensure a uniform application, keeping the wastage of this expensive material to its bare minimum.

You may opt for any of the insulations: batt, cellulose, or spray foam to realize that a well executed insulation causes a substantial reduction of up to thirty percent in your heating costs. You are not helping yourself alone, but the environments too. Check with your local insulation installer the most suitable way of insulating your attic.

Roofing Insulation Types To Consider

Do you realize that the most weather-beaten part of your home is its roof that continues to bear all the burden of ever changing weather all thru year and year after year? That makes it difficult to find out the best insulation to be provided on the roof. It continues to bear hot sun for long hours, more so in summers. And, if you happen to be living in Utah, or California this heat can be worse. And, don’t forget the harshness of melting snow in winters.

If you are in the process of remodeling your home or making a new one, you can ill afford to be stingy in certain areas, and roof and walls are two such areas with roof being a major area. Going for the best quality of materials and products doesn’t necessarily mean that you have to spend lots of money. There are ways and means to get the desired items and affordable prices.

Cellular glass insulation is categorized as commercial grade. It has been used as an insulating material for long. It was patronized as an insulating material in 1943 as it was realized to be extremely durable. Even today it is being used for the same reason. Unless you provide adequate and proper insulation on your roof, it will not be able to able to prevent the effects of outside weather to the interiors of your home. That means in summers, it will not be able to stop heat from entering inside while in winters it will not be able to contain the inside heat that you might be generating at an expense. That’s why the subject needs a serious consideration at your end, any insulation just won’t do. If you overlook this important aspect of your home, you might be exposing your family to some risk that can be easily avoided.



Quite a lot of people are getting conscious about environments and like to use “green” products. Here again you get a variety of materials. Cellular glass is crushed glass that has been mixed with special agents under very high temperatures. It is fire resistant, a characteristic feature that you may like to consider.

It is highly desirable to spare some of your time to study the available options for insulating your roof. At the end of it all, you will appreciate it was time well spent. And, the best time to go for providing an improved insulation is when you are going for a new roof or while constructing a new home.

An easier option will be to study online and know the different options available for roof-insulation. You get a fairly good idea of the prices and also learn the characteristics of different materials available for the purpose. The choice of material also depends on the geographical location, and the climatic conditions of your home, meaning that if a material is suitable for a particular part of the country it may not always suit rest of the country. You can learn all this online and do talk to a roofing expert of your area.

Roof Insulation And Technology

This may come as an element of surprise to most of the present generation of house owners that till about early 1970’s, the U.S. building code did not specify the insulation of homes. It may come as a big surprise to many of the house owners that their present house has inadequate or no insulation at all. The same holds good for many of the commercial buildings.

The present Standard Building Code of the U.S. makes it mandatory for the builder to provide attics with R19 insulation. Generally, the specified grade of insulation is adhered to by providing insulation with fiberglass or cellulose that is blown in at the time of construction of the building. The drawback of the materials mentioned is that over a period of time they get settled and tend to get compacted, thus offering limited insulation.

If ever a survey is carried out to check the insulation of houses and commercial buildings, it will become apparent that most of them lack proper insulation in some form or the other. This will be particularly true for roofs, which start collecting heat coming in from the roof in the absence of perfect insulation. As a matter of fact, no means of effectively insulating the roof were available till recently. Most of the homeowners were content using cellulose or fiberglass as there was no better choice of an efficient insulating material.

The said materials that have so far been employed for the purpose of insulation proved ineffective as they would get fluffy and soft and failed to provide the needed level of insulation. As a consequence, the homeowners had no choice but to bear the heat that radiated down their homes thru the roof.

The latest technology that has been developed calls for the application of a layer of polyurethane foam before fixing the roof over it. Such a roof with a thin layer of polyurethane foam prevents the heat from entering the structure. In winters the same insulation helps to retain the heat within your home.

The new age material is Polyurethane foam. It provides insulation that is twice as strong as normal insulating products. It wouldn’t deteriorate or settle in your lifetime. Once it has been cured, you can walk over it without causing any harm; you won’t be able to make a dent into it under normal circumstances. That’s how tough it gets. Its thin layer applied under the tiles of your roof remains invisible and doesn’t affect the looks or pitch of the roof at all.
