If you wish, you can insulate the walls of a box cooker with various substances. Fiberglass or Styrofoam is usually not recommended since they give off ill-smelling gases as they heat up. Natural substances such as cotton, wool, feathers, or even crumpled newspapers work well. Many people, however, leave the walls empty of any stuffing, preferring instead to place a piece of foiled cardboard as a baffle inside the wall airspace. This makes a lighter cooker and seems to be adequate.

Greenhouse insulation surprises people, but.... A modern greenhouse in good condition can achieve average insulation but the majority of others can only be classed as poor. Surrounding walls are only a problem if they contain combustable materials (e.g. wood or drywall) or material that would melt (e.g. porch screening). See similar questions...

Instead of adding more insulation, you should consider adding a radiant barrier system. This will have a greater effect on your cooling bills because it reflects heat away from the attic before it can reach the insulation and ceiling below. Without a radiant barrier, your roof radiates solar-generated heat to the insulation and, if they are mounted in the attic, your air conditioning ducts below it. See similar questions...

There are various types of insulation available depending on the application it is to be used for and the required U values to be achieved. TIMBER BATTS - A semi-rigid unfaced slab designed to give thermal and acoustic insulation and fire resistance. It is push fitted between studs at 600mm centres and is made from natural materials and recycled glass. Batts are the most common form of timber frame insulation and are used in internal panels and either 90 or 140mm external panel applications. See similar questions...

Why Should Anyone Use Foam Insulation?The American Council For An Energy-Efficient Economy released statistics outlining the amount of money that can be saved by having all building properly insulated. The $13 billion dollars wasted as a result of poor insulation equates to approximately a savings of $200 for each homeowner. If your home is not properly insulated, more energy is needed to keep the home cold when using the air conditioner in the summer, or heating the home in winter. See similar questions...

A reflective insulation reduces radiant heat transfer across air spaces by use of one or more high reflective/low emittance surfaces (Reflectivity of 90% or higher - Emissivity of 10% or less). This rate of heat transfer can be quantified in an R-value (for a specific application). See similar questions...

Assuming local Building Official approval for this type of installation is obtained, you should use the length of nail recommended for that specific material. Add the thickness of the existing insulation and this gives you the nail length required for the fastener to penetrate ¾" or more into the sheathing. Refer to the CSSB's Exterior and Interior Wall Manual. See similar questions...

Most homeowners find it easiest to use batt insulation. Always use unfaced batts, as the paper of foil vapor retarder can trap water vapor in the original insulation, causing moisture problems. If possible, install the new insulation perpendicular to the attic floor joists to reduce heat loss through the joists. Loose fiberglass or cellulose can also be used, by pouring it and leveling it with a board or other implement. See similar questions...

Either loose fill (typically fiberglass or cellulose) or batt insulation (usually fiberglass) will work well. Batts are easier to install yourself, while many contractors find loose fill easier and less expensive to install. See similar questions...

Yes. Fiber glass may cause itchiness and temporary skin irritation in many people handling the products. With respect to more serious effects, fiber glass insulation is one of the most thoroughly tested building materials in use today. Nearly 70 years of extensive research and comprehensive reviews by independent research organizations have concluded that there is no convincing evidence that exposure to fiber glass is associated with respiratory disease or cancer in people.

Properly installed fiberglass does not settle more than 1% and maintains it’s thermal performance. Most cellulose products settle over time at a rate of about 20% and may loose 20% of its R-Value. The R-Value of Fiberglass does not deteriorate over time. Cellulose can sometimes loose R-Value over time. Insulation can loose R-Value when wet. Fiberglass is not absorbent. (If it becomes saturated due to flooding, etc., it should be replaced. See similar questions...

Our spa covers use virgin EPS (expanded polystyrene) foam core for their insulation. We do not use recycled foam insulation because it tends to gap and is less reliable. We use 1 lb, 1.5 lb and 2 lb EPS foam insulation in our covers. The pound rating refers to the insulation's weight per cubic foot. A higher weight rating (density) means increased top strength and a reduced capacity to absorb moisture (see How much weight can your spa covers hold?). See similar questions...
