Doorbell Installation FAQs, answered by experts

Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.

Insulation can be easy to install, depending on the condition of your walls, but there are many safety considerations and potential challenges involved. For example, most types of insulation are made from materials that can cause irritation if inhaled or if they come into contact with your skin. Additionally, installing insulation incorrectly can actually make moisture issues in your home worse.

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process.

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

Insulating your ducts offers several benefits, including:

Improved energy efficiency: Duct insulation prevents energy losses, reducing heating and cooling costs.
Cost savings: Lower energy bills make insulation a cost-effective investment.
Environmental benefits: Enhanced efficiency reduces your carbon footprint.
Consistent comfort: Insulated ducts help maintain a stable indoor temperature.
Better indoor air quality: Reduced allergens and pollutants improve air quality.
