Knauf EcoRoll unfaced fiberglass insulation with ECOSE Technology Knauf EcoRoll unfaced fiberglass insulation with ECOSE Technology is a leading sustainable insulation. All of our rolls are bonded with the revolutionary industry-transforming plant-based ECOSE Technology. Insulation R-value is only valid in still air. If you have a breeze going through your attic from soffit or roof vents it will degrade the R-value of exposed fiberglass insulation.

The best are gained by decking over the insulation , using a sheet product over exposed fiberglass insulation, or sealing up the attic completely and using a foam product under the roof deck to make the attic an enclosed space. I know where I live there are minimum R-value requirements for insulation on exterior walls, there may be similar requirements where you live. Reflective insulation : This type of insulation is most effective in reducing downward heat flow.

Radiant barrier: Especially useful in hot, sunny climates, this type helps keep homes cooler. Eco Fill Wx fiberglass blown-in insulation from Knauf Eco Fill Wx fiberglass blown-in insulation from Knauf is a leading sustainable insulation solution for open attic applications. Eco Fill Wx is Greengard Gold certified to meet the most stringent indoor air quality standards contains no Red List chemicals and is validated to be free of formaldehyde. The R-value lets you calculate how much heat will move through a certain wall area depending on the temperature difference between the indoor and the outdoor air. High R , radiant and vapor barrier.

Fiberglass loose fill insulation offers the lowest insulation value, at about R2. Rock wool offers Rto R3. Standard fiberglass insulation batts or blankets provide an R-value of 2. Most manufacturers produce an R-batt that fits into a 2-by-4. This semi-rigid batt has a unique flexible edge designed to compress as the batt is inserted into walls, attics, ceilings and floor frames. A standardized insulation rating system ensures consistency, with insulating materials rated in R- and U-values.

Rinsulation when using standard fiberglass batt insul. Rvalue with standard fiberglass batt. If you go with other forms of insulation such as spray foam then the R value per inch is greater.

The Higher R-Value the Better The number next to the R is just a rating of its insulating power. The higher the number the better job the insulation will do at keeping heat in or out of your home. In building and construction, the R-value is a measure of how well a two-dimensional barrier, such as a layer of insulation , a window or a complete wall or ceiling, resists conductive flow of heat.

Either way, you have the thermal short circuit from the studs The Rand Rare just laboratory numbers for the insulation part of the wall. Rshould be better than Rby a little bit in the wall. If you have steel studs instead of woo then the Rand Rwalls would be about the same because of high conductivity of the steel.

The R in R-Value stands for Resistance. So what is insulation Resisting? This resistance slows heat down and keeps it on the right side of the wall. Spray Foam or Spray Polyurethane Foam (SPF) is created using two separate chemical compounds which are heated then sprayed simultaneously through specialized equipment. The proper heating and mixture of the chemicals in a reaction that creates foam insulation.

A contractor will come and open up a hole in the wall, pump in a cellulose insulating material, and then patch up the opening. Closed cell spray foam has the advantage of not requiring a vapor moisture barrier, and it also sports a very high R value, making it an ideal choice for insulating basements (and first and second floors alike). Going from R-to R-just involves using a different insulation , but going from R-to R-(the whole-wall R-value for 2xwalls) requires going from 2xto 2xwalls and thus more insulation , more lumber, and doors and windows with wider jambs. I went to my local bigbox to buy insulation , and I can get ror rfiberglass for 2xframing. Need about 4sq ft (doing all walls).

It could mean a tax credit, too. Milton-based stone wool insulation manufacturer ROXUL Inc. Selection, quantities and rebates may vary from one store to another.

The clearance items cannot be transferred between stores. This offer is valid at participating locations only and cannot be combined with any other offer. The type of insulation used can be based on the area of the house needing insulation as well as the cost. The R-Value of Fiberglass insulation is 3. JM POLYISOCYANURATE ROOFING PRODUCT LINE. Owens Corning is your trusted partner for all building solutions needs.

Explore our insulation products to help with your next building project. Our building department required Rfor all exterior walls - however with 2xstuds this would have been impossible without the polyiso insulation. This provides a combined Rvalue which satisfied the building inspector. For property owners, it is important to understand the differences between soundproofing and sound absorption insulation.

If you hear noise from a different space, you likely need soundproofing insulation , as this type of insulation stops noise from traveling from one room to another.
