Absolute home insulation types: advantages & disadvantages

Absolute home insulation

Absolute home insulation upgrades are a great way to lower your heating and cooling costs.

And most of it is diy-able. Read on to learn about the different types of installation, cost, usage, and whether you should diy or hire a pro.

Beds and blankets

It is the most common type of protection. It comes in rolls that are easy to carry and transport. It’s best suited for diy projects, but it carefully cuts things to fit plumbing, wiring, and electrical connections. Wrapped in the wrong places, it loses efficiency – sometimes up to 50%.

Fiberglass batts and blankets

Advantages: widely available and popular, standard widths and thicknesses are designed to fit between studs, joists, and beams. Paper- and foil-faced versions with stapling flanges make installation easy.

Cons: it can be scary to put on – you’ll need protective clothing. Rolls of fiberglass must be cut by hand to fit the area. It compresses easily, which causes it to lose its insulating properties.

  • Environmental issues: phenol formaldehyde, linked to cancer, is being phased out as a preservative. Labels warning of cancer risk from inhaled fibers are being removed because regulators have concluded that the fibers are readily absorbed into the lungs. Recycled content can be up to 60%.

Common uses walls, floors, ceilings.

Diy or pro? Diy

  • Price: $0.64 – $1.19 per square foot.

Rockwool batts and blankets

Advantages: more fire resistant than fiberglass. It is impossible. The springs are in the form of opposite springs, so the installation is staple-free and fast.

  • Cons: not widely available; retains moisture – if allowed to remain moist, it can prevent mold growth.

Common uses walls, floors, ceilings.

  • Diy or pro? Diy
  • Price: 80 cents per sq. Ft.

Cotton batts (aka “blue jeans”)

  • Advantages: it is not itchy. It comes in easy-to-handle lines. It is easy to cut to fit around the pipes.
  • Cons: not widely available and more expensive than other bets.

Environmental issues: it contains approximately 85% recycled fiber and requires less energy to produce. It has borate fire retardant, which also prevents some insects.

  • Everyday use: walls
  • Diy or pro: diy
  • Cost: about 15-20% more expensive than fiberglass

Loose-fill insulation

This absolute home insulation consists of fluffy strands of fiber that are blown into attics and walls by a particular machine. 

Free-fill fiberglass

Advantages: perfect weight for attic applications over ½-inch drywall ceilings by making every 24 inches.

  • Disadvantages: the product is so soft that weak applications can lose half of its effectiveness in the extreme cold unless it is wrapped with a blanket covering or full-density loose fill 
  • Environmental issues: like fiberglass batts and blankets, formaldehyde is not an issue with up to 60% recycled content.
  • Everyday use: ceilings

Diy or pro? Installing an open attic space is easy if you are a skilled diyer. You will save up to 70% over the pro price. Check to see if you can rent an air conditioner from your local absolute home insulation or rental store. But if the task is more complicated, the hinda pro will undoubtedly make the installation meaningful in terms of energy saving.

Cost: 30 cents per cubic foot.

Loose-fill cellulose

  • Pros: works at all temperatures and may do better as the air cools.
  • Cons: too heavy for attic installation; the ceiling should have 5/8-inch drywall or create 16 inches. Over time, it can settle about 20%, reducing its effectiveness.
  • Environmental issues: fibers are too large to stay in the lungs; dust is the only problem. The production of cellulose insulation is usually around 85% post-consumer recycled paper, plus 15% fire retardant. That usually makes a borate compound, which also helps to repel insects.
  • Everyday use: ceilings, existing closed walls or opening new wall holes, unfinished under the roof, other hard-to-reach places.
  • Cost: 31 cents per cubic foot.

Structural insulated panels

Structural insulated panels (sips) have high energy savings of 12% to 14%, but they are expensive. They usually come in 4-by-8-ft. Sheets, although some manufacturers make them as large as 8-by-24 feet and are used primarily on new construction.

If you are replacing siding, roof, or adding, these boards cover all walls, including molding. Some sheets have tongue-and-groove edges to create solid and energy-efficient seams. The absolute home insulation is also used for basement and crawl space walls. If you are facing a residential area, building codes often require that the material be covered with a layer of drywall.

Polystyrene sips

This type of sip comes in two types: extended (eps) is the most expensive and has the lowest r-value. Extruded (xps) type is usually blue or pink; it is more robust and seals moisture better than eps.

  • Pros: lightweight, easy to install.

Disadvantages: must be cut to fit pipe and other wall penetrations, leaving gaps that must be filled with foam sealant. It’s not about style – you can’t nail anything to it. Insects and insects can get inside them.

It is best to treat the panels with an insecticide before use. Also, they are air-tight, well-constructed sip structures that may require air-conditioning to maintain and meet building codes.

Environmental issues: the panels emit toxic fumes when burned. Although scraps and scraps can be recycled, they rarely are; instead, they can end up as plastic waste in rivers and oceans.

Common uses new walls, ceilings, floors, roofs.

  • Diy or pro? You can do it yourself, but since these panels are ideal for new construction or a complete replacement, you already have a contractor.
  • Price: eps: $6 for a 0.5-inch-thick, 4-by-8-ft. 

Polyisocyanurate sips

R-value: 5.6-7.7 per inch.

  • Advantages: higher r-value per inch of any insulation with thicknesses ranging from ½ inch to 2 inches. It is usually faced with foil, which acts as a moisture barrier. Easy to install.
  • Disadvantages: because the foil is moisture resistant, it should not be used where there is already a moisture barrier. More expensive.
  • Environmental issues: the panels emit toxic fumes when burned.

Common uses new walls, ceilings, floors, roofs.

  • Diy or pro? Just like eps and xps, you may be using a contract.
  • Price: $22 for a 1-inch-thick, 4-by-8-ft. Sheet.

Spray foam

Spray foam insulation is more expensive than batt insulation but has higher r-values. It also forms an air barrier, which can eliminate other weather jobs, such as caulking.

This plastic insulation continues like water and expands to fill the existing space, closing all gaps and cracks and stopping air leakage. Pros spray a mixture of foam absolute home insulation in production mines; when dry, the excess is cut off, leaving a flat, even surface.

Open-cell polyurethane spray foam

  • R-value: 3.5 to 3.6 per inch.
  • Benefits: stops air movement.
  • Cons: this allows water vapor to pass through, so a moisture barrier is still needed in some situations. It requires professional installation.

Environmental issues: often called half-pound foam, this absolute home insulation contains very little petroleum-based or plant-based plastic. Chemicals and vocs are released during use and while curing, can cause asthma and other serious health problems, so wait up to three days to re-enter.

Common uses walls, floors, ceilings.

Diy or pro? Although diyers can buy sealants for small jobs, such as filling the gaps around the door, you need a pro with the necessary equipment to seal the walls, roof or ceiling, and floors, especially if you want to get the highest r-value possible.

Cost: $0.44 to $0.65 per board foot

Closed-cell polyurethane spray foam

  • R-value: 6.0 to 6.5 per inch.
  • Advantages: stops the movement of moisture and air.
  • Cons: a little expensive. It requires professional installation.

Environmental issues: it uses explosives that have a potential for global warming and is often called 2-pound foam; it uses more material than open-cell foam. The situation is similar to open-cell foam.

Common uses walls, floors, ceilings.

  • Diy or pro? A professional.
  • Cost: $1 to $1.50 per board foot
