Whether you’re renovating an existing room, expanding your living space with an addition or building a brand new home or cottage, choosing the right insulation for the project is extremely important. Although insulation will represent only a small fraction of your budget, the choices you make will affect the quality of your finished project and the ongoing costs of heating and cooling your home. Additionally, your decision will have an impact on the environment.
ROXUL COMFORTBATT® stone wool insulation products are designed as a thermal insulation for wood and steel frame construction. This semi-rigid batt has a unique flexible edge designed to compress as the batt is inserted into walls, attics, ceiling and floor frames. The flexible edge springs back, expanding the batt against the frame studs to give a complete fill. COMFORTBATT®compensates for normal variations in stud centers caused by distortion or warping. The special flexible characteristic at the insulation edge ensures the expected R-value is achieved.
- Batts compress or expand between frame studs or joists for complete fill
- Fire resistant, non-combustible with melting point of approximately 2150°F (1177°C)
- Water and moisture resistant; repels water to protect walls and studs
- Does not rot, promote mildew, fungi, or bacteria
- High R-values of R10, R14, R15, R22.5 and R24
- Sag resistant for tight fits, never loses shape
- Easy to handle on jobsite; easy to cut with serrated knife
- Chemically inert; non-corrosive
- ROXUL can contribute to earning LEED® points
WHICH INSULATION DO YOU NEED?
Before the you begin, you need to verify the size of the cavities the insulation will be applied (generally 16” or 24”) and calculate how much is needed.
WHERE SHOULD YOU INSULATE?
Ideally the whole home should be insulated from attic to the crawl space. Having the proper insulation and gap sealing in all areas will dramatically improve the energy efficiency of the home. Common insulation projects include attics, crawl spaces, exterior and interior walls, basements and ceilings.
WHAT IS FACING?
Either Kraft paper or plastic that is attached to the insulation to help control moisture, mold and draft.
DO YOU NEED A VAPOR RETARDER?
Vapor retarders are typically recommended for the interior side (i.e., the “warm in winter” side) of above-ground framed walls in your home such as bedrooms, bathrooms, garages and attics. A vapor retarder is not required for basement walls, walls made of materials that can’t be damaged by moisture or freezing, or any parts of walls that are below ground.
WHAT TOOLS DO YOU NEED TO INSULATE?
Tape Measure for measuring insulation
Straightedge (yardstick or 2 x 4) for cutting insulation
Utility Knife for cutting insulation
Stapling Tool for attaching faced insulation or vapor barrier to framing and studs
Putty Knife or screw driver for forcing pieces of insulation into small places
Caulking gun & Caulk to seal floored ceiling plates and other gaps through which air may flow
Dusk Mask to minimize any irritation from breathing airborne particles
Safety Glasses or Goggles to protect eyes from airborne particles or other potential hazards
Long pants, long shirts and gloves to help minimize skin contact with insulation and insulation dust
WHAT IS R-VALUE?
R means resistance to heat flow. The higher the R-Value, the greater the insulating power. As R-Value increases, so does energy efficiency and home comfort. The colder, or warmer, the climate, the higher R-Value needed to maintain energy efficiency and comfort.
Depending on where you live and the part of your home you’re insulating (walls, crawl space, attic, etc.), you’ll need a different R-value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy’s (DOE) ranges for recommended levels of insulation below.
