What to Look at When Choosing Insulation

Insulation is often needed to control room temperatures, restrict sound travel, and control room air quality. However, there isn’t a one-size-fits-all solution when it comes to purchasing insulation. Each consumer needs to look at what they are trying to accomplish by installing new insulation and match their objective(s) with the right option. With that in mind, just below are key factors that warrant consideration.

Air Duct Insulation in Denver metro area

Efficiency level

An insulation’s efficiency at controlling room temperatures is determined by its R-value rating, which is effectively its ability to resist the flow of heat.

Fire resistance

Fire resistance refers to an insulation’s ability to stunt the spread of fire, which some insulations do naturally while others require a fire-retardent treatment.

Noise reduction

Noise reduction refers to an insulation’s ability to block sounds coming from the outside to the inside or sounds that might travel from room to room.

HVAC Duct Insulation

What is Duct Work or HVAC Duct Insulation?

The ducts that you see in your walls and or attic are typically attached to your central HVAC. These ducts serve to promote the flow of cool and clean air from your HVAC unit to each room in the house. The purpose of a duct insulation wrap is to prevent heat from infringing on the cool air that flows throughout the house. It also serves to keep dust particles and pollutants from getting into your HVAC system. If by chance insulating your home or business seems like more than you can handle, a good Denver insulation company, that being Red Rocks Home Insulation, is standing by to help.

Frequently Asked Questions

What is duct insulation?

How to install insulation around an HVAC duct?

The materials you will need include the insulation batts, a utility knife, the manufacturer’s adhesive tape, and safety goggles. The process starts with measuring the insulation pieces to match the ductwork and cutting it followed by applying and securing the insulation in place.

How to identify asbestos duct insulation?

If you live in an older home that still has the original insulation, there is a high likelihood that the insulation includes asbestos. That would not be a good thing as far as you and your family’s health would be concerned. In most cases, you can identify asbestos with a visual inspection. You’ll want to look for fibrous, fluffy, or powdery materials that are white or gray in color.

How to wrap insulation around a duct?

After measuring and cutting your ductwork insulation, you’ll be ready to wrap the ducts. It would be best to wrap from the bottom to the top so the seam will be easy to access. After the insulation is in place, you will need to secure it with tape. The last step would be to look for open seams or gaps and seal them with addiction insulation.
