Mineral wool vs fiberglass insulation | everything you need to know
Stone wool and glass wool insulation are two of the most commonly used insulation types in residential construction. We’re going to cover their main differences as well as their pros and cons.

Stone wool. Its main ingredients are basalt rock, slag, coke and recycled stone wool waste. Basalt rock is a dark, igneous rock formed from the rapid cooling of molten lava. It makes up 98% of the final product. Slag is a byproduct of the smelting of metals like iron, copper, lead and nickel. Coke is made by heating coal or oil in the absence of air. The most popular stone wool manufacturer is Roxul or Rockwool. Comfort Batt is a semirigid product used inside homes on walls connected to the exterior. Comfort Board is a compressed, rigid product used outside homes for continuous insulation. Safe n Sound is used in interior partitions.
Fiberglass or glass wool insulation. Its main ingredients are sand or silicon dioxide, soda ash or sodium carbonate, limestone or calcium bicarbonate and crushed up recycled glass called cullet. The most popular fiberglass manufacturer is Owens Corning. Their EcoTouch Insulation is available in batts, rolls, and blownin loosefill.
Cost differences. 6 pieces of 16inx48in R30 Rockwool insulation costs $61 at Lowe’s. This equivalent 16inx48in R30 Fiberglass insulation costs $64 at Home Depot but it contains 11 pieces. Stone wool is almost twice the price of fiberglass. Since stone wool 3 times denser it is also heavier. A single batt of R30 stone wool weighs 6.6 pounds while an equivalent batt of R30 fiberglass weighs 3 pounds.
Both of these insulation types operate on the insulating property of air trapped between the fibers. This loss of R value over time is called thermal drift. The high density of the stone wool equals more trapped air and better sound absorption properties than fiberglass. Stone wool insulation is naturally hydrophobic or waterproof because it is made of basalt rock. Fiberglass on the other hand isn’t waterproof. It can absorb water and moisture, become compacted and lose all insulating properties. Stone wool is naturally fire resistant up to 2000F because it has a high melting point. Fiberglass is not as fireresistant, it will burn. The kraft paper or foil facing will make it burn even quicker. Stone wool is easier to install because the dense, firm batts frictionfit into place and don’t require any stapling both on the walls and ceiling. Fiberglass is floppy, so it needs to be secured with staples or wire.
You must wear gloves, long sleeved shirts and a respirator when handling both of these materials. If it touches your bare skin, tiny shards of rocks or glass will be embedded in it and causes rashes. The marketing for their “recycled content” is very tricky.
Vapor permeability is the ability to allow movement of water vapor molecules through the material. I’ll make another video that dives into permeability and perm rating but rock wool is vapor permeable. If it’s used as continuous exterior insulation it allows your facade to breathe and dry out. Fiberglass is also vapor permeable, but you have to be careful with the orientation of the foil or paper faced batts. They must face inward in cold climates and outward in warm climates.

Using a Froth Pak – DAP System 600 Spray Foam Kit
DAP Touch ‘n Foam Pro System 600 spray foam kit
Article: https://www.aconcordcarpenter.com/prosystem600sprayfoam.html
The DAP Touch ‘n Foam Pro System 600 is a 2component polyurethane foam kit that covers approximately 600 board feet or 50 cubic feet and can effectively seals air leaks and insulate repairs, renovations, and new installations.
The DAP Touch ‘n Foam Pro System 600 is a completely selfcontained, 2component foam system that is portable and disposable. Complete with colorcoded hoses, ergonomic foam applicator, and all the necessary tools to get started. It is designed for larger insulating (up to 2 inch fills), sealing, patching and filling applications. The applicators dispense a quick, consistent flow of rapid curing (60 seconds) foam capable of insulating stud wall cavities, gaps, cracks, expansion joints, and other sources of air leakage.
Closed Cell Spray Foam Best Practice
When insulating, we feel that the Best Practice is to use closed cell spray foam to fill the cavity and achieve the desired Rvalue. You can learn more on this method here. Best practice for basement insulation
Fiberglass insulation while still popular is not considered best practice as an insulator. That is because it is NOT a good air barrier or vapor barrier, it performs poorly in very cold climates. In colder climates a poly layer of plastic is added over the insulation, but experience and research has shown that installers are not able to seal this plastic well enough to create a 100% vapor barrier.
Spray Foam Still the Best Choice For Water Vapor Barrier
Depending on where you live [Climate Zone] you may be able to get away with 1inch of closed cell spray foam. We recommend 2inches, as colder areas need more. The goal is to seal air leaks, and to prevent warm moist interior air from meeting color exterior framing surfaces which can produce condensation. By keeping the floor joist, rafter bay or wall stud bay above the dew point, condensation cannot form which will prevent mold growth and rot.
Using the Touch ‘n Foam Pro System 600
Closed cell spray foam insulation is the only product that acts as an insulator and an air seal. To ensure that you achieve both of these goals make sure to completely follow the directions of the Touch ‘n Foam Pro System 600 and do the following:
Read and follow the instruction manual for proper setup, instructions for use, clean up, safety cautions, and storage.
Wear proper protective clothing [PPE] including an organic vapor respirator with plenty of ventilation.
Ensure proper operating temperatures for the system 600 kit. [chemical 70 to 90°, surfaces 60 to 90°, air temperature is 60 to 90° ]
If you stop applying the spray foam for more than 30 seconds, replace the nozzle. To avoid this exercise the nozzle in a trashcan to keep from curing.
Two nozzles are provided. The yellow fan nozzle is for a wide spray pattern and the clear nozzle is for a narrow spray pattern.
The foam should be an offwhite color and be cured to touch within 30 to 60 seconds.
CAUTION: Spray foam should only be applied where it can freely rise perpendicular to the substrate. You should avoid using closed cell spray foam to fill restricted areas. Depending on the thickness of this cavity, excessive exothermal heat may cause form discoloration, smoldering or even fire.
Do not use the spray foam against any material that reaches 250° or more, such as chimney pipes, steam pipes or heat vents.
Install 100% coverage of foam to a 2inch depth. [minimum]
Above grade framing: ensure fill coverage in all framing bays. Any overspray can be trimmed down later with a hand saw.
Basement walls: ensure foam seals and covers seams at subfloor, rim joist, sill plate down to the wall cavity. Seal all air gaps.
Apply the initial layer of foam in a 1/2 inch wet layers. This initial layer can also help warm the substrate.
Subsequent layers can be installed in 1 inch wet layers, the foam will produce a 2X to3X original expansion volume.
For 1 inch layers, allow approximately 15 minutes to cure between next layer, to avoid overheating.
Flash and Batt Using DAP Touch ‘n Foam Pro System 600
Flash and Batt Insulation refers to using 2inches of closed cell spray foam [R14] to ensure that all air leaks and vapor paths are sealed. The closed cell insulation is then followed with fiberglass batts in the remaining space to add additional insulation and meet required RValues. This method is an option to someone looking to save costs in closed cell spray foam while still improving the wall’s thermal and vapor permeability performance. Flash and batt is most often seen in DIY or remodeling applications.
The DAP Touch ‘n Foam Professional system 600 Spray Foam Kit is a great solution for quick and easy spray foam application for repairs and renovations, and new installations.
