Yes, you generally should tape insulation seams, especially if the insulation has a vapor barrier (like kraft paper or foil) or if you are installing continuous rigid foam board. Taping prevents conditioned air from escaping, blocks drafts, and stops moisture from penetrating the wall cavity.
Whether you should tape insulation seams depends entirely on the type of insulation you are using. Taping is critical for rigid foam boards and vapor retarders to block airflow and prevent condensation, whereas traditional fiberglass batts only require proper stapling without taped seams.
While it may appear harmless to the naked eye, it actually contains thousands upon thousands of small shards of glass and sand that can make their way onto your skin, eyes or even inside your lungs. If you've ever touched fiberglass insulation with your bare hands, you're probably well aware of its effect on the skin.
Unfaced insulation is great for new construction, remodels, walls, floors, ceilings, basements, attics and crawlspaces. It's best used for interior wall applications that do not face the outside and also in rooms that don't need moisture control, like living rooms, dining rooms and studies.
What time of year is Insulation cheapest?
Mice are curious and always searching for safe, snug, and warm nesting sites. Attics filled with blown-in insulation provide an excellent option–from the mice's point of view. As long as there is a ready food source. Mice are omnivorous and will eat and chew on almost anything including wood and electrical wires.
When balancing upfront cost and overall thermal efficiency, the cheapest and most effective standard insulation is fiberglass batt insulation. However, if you are looking for long-term savings through superior air sealing, dense-pack cellulose often provides the best overall value.
Foam insulation is a common target because it's easy for them to chew through. The material offers little resistance, allowing mice to create tunnels or nests within the insulation. But mice aren't just interested in chewing for the sake of it—they're also drawn to the warmth and shelter insulation provides.
Yes, homeowners can add new insulation over existing insulation in most cases. This approach works well for attics, walls, and floors where the current layer remains intact and undisturbed. Building codes and energy experts often support this method to boost thermal performance without full removal.
The healthiest, non-toxic insulation for your home is natural sheep's wool or hemp insulation. These materials contain no chemical binders or formaldehyde, actively regulate indoor humidity to prevent mold, and do not off-gas.
Because spray foam can trap moisture, hide the condition of the roof, make it difficult for surveyors to inspect, which means risks like timber decay, dry rot, and not forgetting increased fire risk. If you've got it or you're buying a property that does, this is something you need to know upfront.
Yes, your lungs can get rid of fiberglass, but how effectively they do it depends on the size of the fibers and where they end up in your respiratory tract.
That pink fluffy stuff inside your walls is fiberglass insulation. It is primarily made from recycled glass and sand melted down and spun into thin fibers.
It depends on your climate and the type of insulation. In very cold climates, plastic serves as a necessary vapor barrier on the warm side of the wall. However, in warm, humid, or mixed climates, installing plastic can trap moisture and cause mold.
Despite the number of adhesive tapes available to buy, none should be used as a substitute for electrical tape as a lack of essential qualities will make them unsafe in similar situations.
Is Self-Regulating Heat Tape a Fire Risk? No, self-regulating heat cable is not a fire hazard when properly installed. These cables are specifically engineered to be safe in contact with any common roof or pipe materials and to avoid overheating.
10 Insulation Installation Mistakes to Avoid
Cellulose Insulation
The typical lifespan is 20 to 30 years, with degradation beginning as early as 15 years after installation. As with other types of insulation, severe weather or outside interference can reduce the lifespan.
The Amish control mice through non-chemical, self-sustaining methods, relying on active trapping, natural scent repellents, and structural exclusion. Rather than using commercial poisons, they focus on physical barriers and natural predators to keep rodent populations in check.
Rats are a primary food source for a wide variety of animals. Their most significant natural and artificial predators include:
Potential problems with spray foam insulation
reduce air circulation and ventilation within a roof space. lead to dampness and condensation on the underside of a roof because it forms an air barrier and stops moisture from escaping. place timber-framed roofs at risk of decay.
Closed cell spray foam is rigid once set. It is a better thermal insulator and was previously sold to stabilise failing roofs. But if it has been used inappropriately or installed poorly, it might put stress on timbers, restrict air circulation and put them at risk of decaying.
Several household items can temporarily trap heat or block drafts. However, for permanent structural fixes, always opt for building-code-approved materials. Common temporary insulators include:
Yes, you can physically compress R19 fiberglass batts into a 2x4 wall, but it is not recommended.
