Local Climate Considerations
St. Louis experiences a humid continental climate, characterized by hot summers and cold winters. These climate extremes put a significant strain on home heating and cooling systems. Effective attic insulation can help maintain a stable indoor environment, regardless of the outside temperature fluctuations. By enhancing your attic insulation, you can significantly cut down on heating expenses during extreme winter conditions, while also keeping your cooling costs in check during the hot and humid summers.
In St. Louis, high humidity levels can contribute to moisture buildup in the attic, leading to potential structural damage and mold growth. Our insulation solutions are designed to not only regulate temperature but also manage moisture levels, safeguarding your home from these common issues. Our team will assess your current insulation and suggest improvements tailored to the unique climate challenges of the region.

“We used Building Envelope Experts for our insulation. They did a superb job, not only adding insulation on top but taking out the old insulation, sealing up any air leaks, and then adding new insulation on top. Not only have our heating needs gone down significantly, but our house is so much quieter now. My kids woke up during every thunderstorm for years and now sleep through them all!”

About Our St. Louis Insulation Services
Blown-In Insulation
Just like it sounds, blown-in insulation is a method of attic insulation that is blown into uninsulated spaces through a long hose. Consisting of cellulose, blown-in insulation slows the airflow of conditioned air leaving your home.
This type of insulation is particularly advantageous in hard-to-reach places or those with unique configurations that make other types of insulation less effective. The ability to conform to any space without cutting or fitting often results in a more thorough and efficient insulation job. Additionally, blown-in insulation can be installed quickly and with minimal disruption to your household, making it an attractive option for those looking to improve their home’s energy efficiency swiftly and effectively.
TruSoft Cellulose Insulation
Cellulose is an insulation material manufactured from wood or paper with an easily moldable consistency.
Some of its benefits include:
- Fire retardant
- Pest retardant
- Eco-friendly
- Slows down air better than fiberglass
- Higher R-value per inch than fiberglass
TruSoft cellulose insulation is renowned for its eco-friendly properties, sourced from recycled materials, which help in conserving natural resources while providing superior thermal protection. By choosing cellulose insulation, you contribute to sustainability efforts without compromising on performance. This makes it ideal for those who are environmentally conscious yet demand high efficiency in home heating and cooling.
Building Envelope Experts uses TruSoft cellulose insulation, a proprietary brand of premium cellulose exclusive to licensed insulation contractors in the St. Louis area.
Duct Sealing
Between 20 and 30% of the air moving through your HVAC system is lost due to insufficient duct sealing. Properly sealing the air ducts in your home reduces the amount of air lost through leaks, leading to lower energy costs and a more comfortable home.
Additionally, sealed duct systems may help improve indoor air quality and reduce the number of allergens, chemicals, and other harmful air particles in your home.
On top of all this, it can also protect your HVAC equipment.
Effective duct sealing can drastically enhance the efficiency of your heating and cooling system, making temperature regulation more uniform across your home. This not only ensures comfort but also extends the life expectancy of your HVAC system by reducing the stress on its components. By investing in duct sealing, you can significantly diminish noise levels generated by air movement, contributing to a more peaceful and harmonious living environment.
Signs You Need Your Attic Insulated
Ensuring proper insulation in your attic is essential for maintaining a comfortable and energy-efficient home, especially in the variable climate of Missouri. Here are some signs that indicate you may need to upgrade or replace your attic insulation:
- Increased Energy Bills: If you notice a sudden spike in your heating or cooling bills, it could be due to inadequate attic insulation. Inadequate insulation lets conditioned air seep out, causing your HVAC system to operate more intensely and use extra energy to sustain a comfortable temperature.
- Uneven Temperature Distribution: Rooms that seem overly warm during summer or chilly in winter, even when your HVAC system is running, could suggest inadequate attic insulation. Proper attic insulation helps in maintaining consistent temperatures throughout your home.
- Drafts and Air Leaks: Sensing drafts or observing air leaks near the attic access door, electrical outlets, or along the attic floor indicates insufficient insulation. These drafts can compromise your home's energy efficiency and comfort.
- Ice Dams: In winter, if you notice the formation of ice dams on the roof's edge, it may indicate poor attic insulation. Inadequate insulation can cause uneven roof temperatures, leading to snow melting and refreezing at the eaves, which can damage your roof and gutters.
- Age of Insulation: If your home is more than 15-20 years old and has never had its attic insulation updated, it is likely time for an upgrade. Over time, insulation can settle, become compressed, or deteriorate, reducing its effectiveness.
- Pest Infestations: Rodents and pests entering your attic can harm or displace insulation, rendering your home more vulnerable to temperature shifts.
Investing in proper attic insulation with Building Envelope Experts can help you maintain a comfortable indoor environment, reduce energy consumption, and lower your utility bills. Contact our St. Louis attic insulation professionals today to schedule a comprehensive home energy audit and learn more about our attic insulation solutions tailored to meet your Missouri home's needs.
Regular evaluations of your attic insulation can prevent many common issues before they escalate. A professional assessment will identify areas where insulation may be failing or inadequate and recommend the best course of action to rectify these problems. By doing so, you not only ensure immediate benefits such as comfort and energy savings but also strengthen your home's structural integrity for the long term.
Frequently Asked Questions About Attic Insulation
Why Is My House So Cold in the Winter?
This could be due to what's known as the stack effect: when conditioned air rises and leaks out of the home from unsealed gaps and into the attic. As a result, negative pressure is created in the basement, which then acts like a vacuum, sucking in unconditioned air from outside. During the winter, this causes cold air to be drawn into the basement.
The stack effect is a significant problem for homeowners, not only because it disrupts the comfort of the home but also because their heating and air conditioning bills increase as the HVAC system must work harder to compensate for the air leaks.
In order to reduce the amount of air leakage from your home, it is critical to first address the root of the problem—air leaks into the attic. For help, hire our team for professional attic insulation service in St. Louis County!
Reducing the stack effect not only improves comfort but significantly impacts indoor air quality. By sealing gaps, you prevent the infiltration of outdoor pollutants, allergens, and moist air, protecting your indoor air environment. Proper sealing and insulation can also help in maintaining the home's structural integrity, preventing issues like mold growth and wood rot, which can result from continuous exposure to external moisture and air seepage.
How Often Should Attic Insulation Be Replaced in Missouri?
The frequency of replacing attic insulation in Missouri can vary based on several factors, including the type of insulation used and the conditions within the attic space. Generally, insulation should be assessed every 15-20 years. However, signs of wear like moisture, mold growth, or pest infestation would necessitate a more immediate replacement. Regular assessments by professionals can help you determine the optimal time for an upgrade, ensuring your home remains energy-efficient and comfortable throughout the year.
What Types of Insulation Are Best for St. Louis Homes?
The best type of insulation for St. Louis homes depends on various factors, including the existing structure of the home and individual homeowner needs. Blown-in cellulose and fiberglass are two popular options due to their excellent thermal performance and ability to fill irregular spaces, making them ideal for attics. Additionally, TruSoft cellulose insulation offers eco-friendly benefits, while spray foam provides superior air sealing and moisture resistance, making it highly beneficial for varying climate conditions observed in Missouri.
Is Professional Installation Necessary for Attic Insulation?
Professional installation of attic insulation is highly recommended to ensure optimal performance and efficiency. Trained professionals from Building Envelope Experts can identify areas where heat loss occurs, recommend the most suitable insulation materials, and ensure that installation is carried out flawlessly. Proper insulation installation can lead to substantial savings on energy bills, increased home comfort, and prevention of issues associated with improper installation, such as voids and gaps that reduce insulation efficacy.
What Are the Benefits of Upgrading My Attic Insulation?
Upgrading attic insulation yields multiple benefits, including increased energy savings, enhanced indoor comfort, and improved air quality. In St. Louis, where seasonal temperature swings can be significant, proper attic insulation helps maintain a consistent indoor temperature, reduces the demand on heating and cooling systems, and decreases utility bills. By investing in new or additional attic insulation, homeowners can also increase their property value and contribute to a more sustainable environment by lowering their carbon footprint.
How Does Attic Insulation Impact My Home's Energy Efficiency?
Attic insulation plays a crucial role in a home's overall energy efficiency. It acts as a barrier to thermal transfer, keeping the desired temperature inside while blocking external temperatures from affecting indoor comfort. In St. Louis, where summers are hot and humid and winters can be bitterly cold, proper insulation reduces the workload on HVAC systems, leading to energy savings and a prolonged system lifespan. Moreover, effective insulation reduces drafts, prevents ice dams, and enhances overall indoor air quality, supporting a healthier living environment.
