Professional insulation installation in Richmond VA can help homeowners:
DOE and ENERGY STAR both note that the correct product choice and installation quality are essential to insulation performance.
Below is the full service-page version covering the main insulation types used in Virginia and across the U.S.
Fiberglass batt insulation is one of the most common insulation materials used in homes. DOE classifies fiberglass batts and rolls as blanket insulation, and ENERGY STAR also lists fiberglass among the standard batt-and-roll insulation materials.
Fiberglass batt insulation traps air within dense glass fibers to slow heat transfer through walls, floors, and ceilings. DOE notes that it performs best when installed correctly without gaps or compression.
R-3.0 to R-4.3 per inch depending on product density.
Walls, floors, ceilings, and many attic applications.
Blown-in fiberglass is a loose-fill fiberglass product installed with blowing equipment. DOE lists fiberglass as a common loose-fill insulation material for attics and enclosed spaces.
It fills irregular spaces and covers obstructions more evenly than batt products in many attic-floor applications.
R-2.2 to R-2.7 per inch in attic applications.
Attic floors and adding insulation over existing attic material when conditions are suitable.
Cellulose is a loose-fill insulation commonly made from recycled paper fibers with fire-retardant treatment. DOE identifies cellulose as one of the main loose-fill insulation materials used in attics and enclosed wall cavities.
It is blown into attics or dense-packed into wall cavities to create a continuous insulating layer around framing, wiring, and obstructions.
R-3.2 to R-3.8 per inch, with dense-pack cellulose often around R-3.5 to R-3.8 per inch.
Attics, retrofit walls, and enclosed cavities.
Mineral wool, including rock wool and slag wool, is recognized by DOE and ENERGY STAR as a standard insulation type used in batt, loose-fill, and some board formats.
It resists heat flow by trapping air within dense fibers and is also often chosen for sound control and heat resistance.
R-3.8 to R-4.3 per inch.
Walls, floors, ceilings, sound-sensitive spaces, and assemblies where fire resistance matters.
Open-cell spray foam is a foamed-in-place insulation product applied professionally. DOE includes foamed-in-place insulation among the products that often require professional installation.
It expands after application to fill cracks, gaps, and framing cavities, helping reduce both heat transfer and uncontrolled air movement.
R-3.5 to R-4.0 per inch. Virginia spray-foam guidance also uses a similar range for open-cell foam.
Wall cavities, attic rooflines, cathedral ceilings, and hard-to-seal spaces.
Closed-cell spray foam is a denser spray foam insulation with a higher R-value per inch than many common residential insulation products. DOE includes it within sprayed and foamed-in-place insulation types.
It expands into cavities and cures into a rigid insulation layer that provides thermal resistance, air sealing, and added moisture resistance. Virginia-focused spray foam guidance also notes that closed-cell foam can act as a vapor retarder at the right thickness.
R-6.0 to R-7.0 per inch.
Crawl spaces, basements, rim joists, tight wall cavities, and selected roofline assemblies.
Rigid foam board is used where continuous insulation or moisture-resistant insulation is needed. DOE lists polyisocyanurate, polystyrene, and polyurethane among common rigid-board materials, while ENERGY STAR also includes EPS, XPS, and Polyiso as standard rigid board options.
Rigid board slows conductive heat flow and can reduce thermal bridging when installed continuously over framing or in foundation assemblies. DOE specifically notes that rigid foam can block thermal short circuits when installed continuously.
EPS: about R-3.6 to R-4.4 per inch
XPS: about R-4.5 to R-5.0 per inch
Polyiso: about R-5.6 to R-6.5 per inch
Exterior continuous insulation, foundations, basement walls, roof assemblies, and specialty applications.
Radiant barriers are reflective systems rather than bulk insulation. DOE distinguishes radiant barriers from standard insulation products because they work by reducing radiant heat transfer instead of insulating the same way fiberglass or foam does.
They reflect radiant heat away from living spaces, especially in attic and roof assemblies.
They do not have a direct standard per-inch R-value comparison like fiberglass, cellulose, or spray foam.
Attics and roof systems where radiant heat gain matters.
DOE and ENERGY STAR both recognize natural fiber products such as cotton and wool, as well as some plastic-fiber batt products, as valid insulation materials.
These materials reduce heat flow by trapping air within their fibers, similar to fiberglass and mineral wool.
Often around R-3.0 to R-3.8 per inch, depending on the product.
Alternative insulation projects, stud bays, and floor cavities.
Insulating concrete forms (ICFs) and structural insulated panels (SIPs) are system-based insulation approaches used more often in new construction or large projects. DOE identifies both as building-system approaches where insulation is part of the structural assembly itself
They build insulation into the wall or roof assembly instead of adding it later as a separate material layer.
Assembly-dependent rather than a single universal per-inch number.
New construction, high-performance homes, and specialty builds.
For central Virginia homes, attic insulation is often discussed in the R-49 to R-60 range depending on existing insulation, assembly type, and whether the recommendation is based on retrofit or code context. Walls are commonly discussed in the R-13 to R-20 range depending on framing depth and whether continuous insulation is used. Crawl-space and basement-wall recommendations vary by assembly and moisture strategy.
SanPro Home Solutions provides professional insulation installation in Richmond VA, helping homeowners upgrade with blown-in cellulose, fiberglass, spray foam, and rigid insulation solutions built for long-term comfort and energy efficiency.
SanPro can position this service around real homeowner problems in Richmond — attic heat gain, under-insulated crawl spaces, aging wall insulation, and insulation replacement after pest or contamination issues.

Everything you need to know before scheduling your SanPro Attic Services
The best insulation depends on the area of the home and the performance goal. Attics often use blown-in fiberglass or cellulose, walls may use fiberglass batts, mineral wool, or spray foam, and crawl spaces or rim joists often benefit from spray foam or rigid board depending on the assembly. DOE and ENERGY STAR both explain that insulation selection should be based on the application, installation method, and required R-value.
Many retrofit discussions for central Virginia place attic insulation in the R-49 to R-60 range, while walls commonly fall in the R-13 to R-20 range depending on the assembly. ENERGY STAR and Virginia code materials both support this general range in Zone 4 contexts.
Yes. DOE specifically identifies loose-fill materials such as fiberglass, cellulose, and mineral wool as strong options for attic floors and irregular spaces because they can be blown around obstructions and into hard-to-reach areas.
Neither is automatically better in every application. Spray foam can provide insulation plus air sealing and often higher R-value per inch, while fiberglass remains cost-effective and widely used when installed correctly. DOE emphasizes that material choice depends on where the insulation is being installed and how it will be installed.
Often yes, especially in attics, but only if the existing insulation is dry, clean, and in suitable condition. Wet, contaminated, compressed, or pest-damaged insulation may need removal first. ENERGY STAR’s retrofit guidance also assumes that many homes already have some insulation and provides add-on recommendations based on that condition.
Insulation may need replacement when it is wet, moldy, rodent-affected, compressed, contaminated, or no longer performing properly. DOE notes that installation quality and material condition affect real-world performance.
