Insulation questions, answered by experts

No, you shouldn’t wrap a towel, old T-shirt, or other porous fabric around your faucets. These materials absorb water, which can make your faucet more likely to freeze. Instead, you want to use waterproof, insulative covers that can seal tightly around the spigots for the best protection against frozen outdoor faucets and pipes.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

In most cases, the building code in your location will determine the minimum amount, in R-value, required for your home's walls, attic, and other spaces. For attics, the minimum R-value amounts start at R30 in the south, R38 in mild climate locations, and R49 in northern states and cold western areas.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

There are two places where you should not place foam insulation: around electrical boxes or near lightboxes. The foam insulation could get inside the electrical boxes and damage the wiring. Spraying foam too close to a lightbox creates a potential fire hazard; it could also cause damage to the light.
