"We had Lake Atitlan Insulation remove our old insulation and replace it with R-38. I enjoyed working with Nanni from the initial meeting to the final step of installing the insulation. Very knowledgeable lady and truly exceptional customer service. A highly recommended insulation contractor."

Insulation questions, answered by experts

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.

Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions. Installing mineral wool and sheep wool requires protective gear. Because of its vulnerability to insects, chemicals are used in its production. Hemp wool is more costly to install than other types because additional tools and labor are involved.

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.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.
