Replace Blown-In Insulation: Upgrade To Foam

We can fullfill every insulation project you can imagine!

As energy costs continue to rise, homeowners are looking for ways to reduce their energy bills. One of the most cost-effective investments a homeowner can make is replacing blown-in insulation with foam. Foam insulation provides an airtight seal that traditional fiberglass and cellulose insulation cannot match.

In addition, it has superior soundproofing qualities compared to other types of insulation materials. This article will provide an overview of how foam insulation works, its benefits over traditional alternatives, and when you should consider upgrading your home's existing blown-in insulation to foam.

Foam insulation is made from polyurethane or polystyrene plastic resin combined with various chemicals that create tiny cells in its structure. These small bubbles trap air and prevent heat transfer through convection currents, thus reducing energy loss from the building envelope.

It also acts as a vapor barrier which prevents warm moist air from entering the wall cavity and condensing on cold surfaces inside the house - another major contributor to energy losses in buildings with inadequate ventilation systems.

Unlike other forms of insulation such as fiberglass batting or loose fill cellulose, foam does not settle over time leading to gaps in the thermal performance of the building envelope.

The superior insulating properties of foam versus other forms of blow-in insulation give homeowners several advantages including reduced heating/cooling costs and better protection against extreme temperatures outside the house.

Moreover, because it’s lightweight yet durable enough to resist mold growth even after decades' worth of use, foam makes it easier for contractors to install than heavier materials like mineral wool or concrete blocks used in non-foam insulated walls.

Finally, since there are no fibers present in foam material – unlike some batts – it doesn't pose any health risks associated with inhalation like those found in fiberglass products commonly used as filler material in attic spaces

Types Of Blown-In Insulation

The insulation of homes is an essential component in the effort to reduce energy consumption and combat climate change. According to a survey by the American Council for an Energy-Efficient Economy, residential buildings are responsible for 21% of total US energy use.

Blown-in insulation is one of the most popular ways to insulate a home, accounting for up to 40% of all installations. Two main types of blown-in insulation materials are available: loose fill cellulose and loose fill fiberglass.

Cellulose insulation is made from recycled paper that has been treated with fire retardants and biocides. It provides moderate levels of thermal resistance (R-value) at an affordable cost compared to other insulation products on the market.

Cellulose also offers superior noise reduction capabilities due its high density which aids sound absorption. On the downside, it tends to settle over time resulting in reduced R-values as well as potential risks associated with mold growth when exposed to moisture or humidity levels above 50%.

Fiberglass insulation is another common type of blown-in product consisting mainly of glass fibers bonded together with binder material such as polyurethane foam.

Compared to cellulose, fiberglass offers higher thermal performance values but can be more expensive depending on the manufacturer's pricing model.

Furthermore, proper installation methods must be followed when installing this type of product so as not avoid creating air spaces between walls where moisture may accumulate leading to mold problems down the line.

Given these limitations inherent in both types traditional blown-in insulation it becomes apparent why upgrading your existing system could bring long term benefits…

Problems With Traditional Blown-In Insulation

Traditional blown-in insulation has several issues that make it an outdated form of home insulation:

  • Poor air sealing capabilities
  • Low R-value, leading to poor energy efficiency
  • Difficulty in creating a consistent level of coverage throughout the entire space
  • Vulnerable to mold growth if exposed to moisture or humidity
  • Potential for fiberglass particles being released into the living environment

These problems with traditional blown-in insulation often lead to higher than necessary utility bills and increased discomfort within the home.

Furthermore, due to its lack of adequate air sealing capability, many homeowners find themselves unable to achieve desired temperatures without running their HVAC system more frequently.

All these factors can add up quickly making upgrading from traditional blow-in insulation essential for cost savings as well as overall comfort levels within the home. With all this in mind, it is clear why upgrading from blown-in insulation is important.

Transitioning now onto a discussion about the benefits of foam insulation…

Benefits Of Upgrading To Foam Insulation

Upgrading from traditional blown-in insulation to foam insulation offers many benefits that can help improve the energy efficiency of a home. First, foam insulation is designed for maximum airtightness and helps reduce drafts in walls, ceilings and other areas of a home.

This air sealing can significantly increase energy savings by preventing conditioned air from escaping through small gaps or cracks throughout the home's envelope.

Second, foam insulation also reduces noise levels within the home due to its ability to absorb sound waves instead of reflecting them as with traditional materials like fiberglass batts.

As a result, homeowners are able to enjoy quieter indoor environments that don't suffer from audible disturbances coming from outside sources such as traffic noise or loud neighbors.

Finally, foam insulation provides superior coverage compared to loose fill materials because it fills every nook and cranny ensuring an even layer of protection across all surfaces it comes in contact with.

It also has higher R-value ratings per inch than most competing products which means greater thermal performance over time without sacrificing space within walls or attics.

By upgrading to this type of material, homeowners can rest assured knowing their homes will remain comfortable year round while saving money on utility costs in the process. With these advantages in mind, one may now consider different types of foam insulation available for use in their own residence.

Types Of Foam Insulation

Foam insulation is a popular choice for replacing blown-in insulation due to its superior energy efficiency and airtight seal. There are two main types of foam insulation: spray foam and rigid foam board.

Spray foam is usually applied in liquid form, which expands after application to fill cavities and cracks between surfaces. It can also be used as an adhesive on the backside of rigid foam panels for added stability during installation.

Rigid foam board is available in sheets or boards, with different thicknesses depending on specific requirements. These panels are often used to insulate walls, floors, and ceilings due to their ease of installation and superior R-value ratings when compared with other materials.

Spray foam has become increasingly popular among homeowners due to its ability to provide excellent soundproofing qualities while still providing adequate thermal resistance. In addition, it offers better moisture control than traditional fiberglass insulation products without compromising indoor air quality.

On the other hand, rigid foam boards have been used successfully for decades because they offer superior durability against extreme temperatures, humidity levels, and pests such as rodents or insects.

Both types of foams can be easily installed by professionals or DIYers alike with minimal disruption to existing structures. With the right preparation, these products can help transform any home into a comfortable living environment that is both efficient and cost-effective.

As we transition into discussing the process involved in installing foam insulation, it's important to note that professional services may be necessary if complete coverage is desired throughout the entire space being insulated.

Foam Insulation Installation Process

Installing foam insulation is a straightforward process. It requires the following steps:

  • Removing existing materials from walls, attic, or crawl space
  • Cleaning and preparing surfaces for installation of new foam insulation
  • Cutting and fitting foam insulation to the desired areas
  • Sealing all joints and seams with caulk or tape

When installing foam insulation in an attic or wall cavity, it is important to use quality products that are designed specifically for this purpose. Foam insulation should be cut to fit neatly into existing cavities and sealed tightly against air leaks.

A professional contractor may also need to open up some interior walls to access hidden cavities where foam can be installed. The contractor should ensure that any newly opened walls are adequately insulated before closing them back up again.

This will help enhance energy efficiency while reducing heat loss through the windows and doors of your home.

Additionally, contractors must take care when cutting large pieces of foam so they don’t accidentally damage other parts of the structure as well as adjacent wiring or plumbing systems which could lead to costly repairs down the road.

For most homeowners, hiring a qualified contractor who specializes in residential insulation installation is recommended due to their expertise on proper techniques and safety protocols involved with performing such work correctly.

Doing research ahead of time on different types of insulating material available helps make sure you get what you need for optimal energy savings at minimal cost over time.

After successfully installing foam insulation throughout your home, remember to check regularly for signs of deterioration such as cracks, gaps between panels, and unevenness along edges which can reduce its effectiveness if not addressed promptly.

With these considerations in mind, investing in high-quality foam insulation now will pay off greatly in terms of both comfort levels inside your home and reduced utility bills in the future.

Cost Considerations And Roi

When considering the costs of upgrading to foam insulation, it is important to factor in both upfront and long-term cost savings. Upfront, homeowners can expect to pay more for foam products compared with blown-in insulation.

However, the improvements in energy efficiency offered by foam insulation often result in significant savings over time due to reduced energy consumption. In addition, while initial installation may be higher than traditional materials, foam has a longer life span, meaning fewer service calls or replacements.

The return on investment (ROI) should also be taken into account when deciding whether an upgrade is worth it.

Because foam insulation provides improved thermal performance and reduces drafts caused by air leaks, homeowners can enjoy lower monthly utility bills as well as increased comfort throughout their home all year round.
