Professional Insulation Services for Homes in New London County

Dynamic Building & Energy Solutions provides professional insulation services throughout New London County, Connecticut. From coastal homes in Mystic and Stonington to inland properties in Norwich and Colchester, we help homeowners improve comfort, reduce drafts, and lower energy costs with properly installed insulation.

New London County’s mix of historic homes, coastal exposure, and seasonal temperature swings makes insulation performance especially important. Our team focuses on whole-home insulation solutions designed for Connecticut’s climate.

Homes with little or no insulation are often to blame for inconsistent indoor temperatures and rising energy costs, especially in older properties. The good news? Many Connecticut homeowners may qualify to have part of their insulation project covered at no cost. Learn More.

Types of Insulation

  • Fiberglass Insulation

    Fiberglass insulation remains one of the most widely used and cost-effective insulation options for homes in New London County. Made from fine spun glass fibers, it is designed to slow heat transfer and improve overall thermal performance throughout the home.

    Versatile for Multiple Areas of the Home

    Fiberglass can be installed in attics, wall cavities, basement ceilings, and floor systems. Its flexibility makes it a practical solution for both new construction and insulation upgrades in existing homes.

    Reliable Thermal Performance

    By reducing the movement of heat between conditioned and unconditioned spaces, fiberglass insulation helps maintain more consistent indoor temperatures during Connecticut’s cold winters and humid summers.

    Helps Reduce Noise Transfer

    In addition to improving thermal comfort, fiberglass insulation can also limit sound transmission between rooms and from exterior sources, making living spaces quieter and more comfortable.

    Cost-Effective Efficiency Upgrade

    Fiberglass insulation provides a budget-friendly way to improve energy efficiency and reduce heating and cooling costs without major renovations. When properly installed and paired with air sealing, it can significantly improve overall home performance.

  • Cellulose

    Cellulose insulation is a high-performance, dense-pack insulation material commonly used to upgrade existing homes in Connecticut. Made primarily from recycled paper fibers, it is specially treated to improve fire resistance and durability while delivering strong thermal performance.

    Because of its density, cellulose is especially effective in older homes throughout New London County where wall cavities and attics often lack sufficient insulation.

    Strong Thermal Performance

    Cellulose provides excellent resistance to heat transfer, helping homes stay warmer during Connecticut winters and cooler during the summer months. Its ability to limit airflow within wall and attic cavities improves overall energy efficiency.

    Ideal for Retrofit Applications

    Dense-pack cellulose is commonly used in existing walls without requiring major demolition. It fills small gaps and voids that other insulation materials may miss, creating a more consistent thermal barrier.

    Sound Dampening Benefits

    The density of cellulose insulation helps reduce sound transmission between rooms and from outside noise, making it a good choice for homes located near roads or coastal areas.

    Added Fire & Pest Protection

    Cellulose insulation is treated with fire-retardant materials that slow flame spread and improve safety. The treatment also helps deter insects and pests.

    Moisture & Airflow Control

    When properly installed, cellulose limits uncontrolled air movement within walls and attics, which can help reduce moisture-related issues and improve indoor comfort.

    Installation Options

    Cellulose insulation can be installed in attics as blown-in insulation or dense-packed into wall cavities. Professional installation ensures proper coverage, density, and long-term performance.

  • Air Sealing Services

    Air sealing is a critical step in improving insulation performance and overall home efficiency. Even well-insulated homes can lose significant energy through small gaps, cracks, and hidden openings that allow outside air to enter and conditioned air to escape.

    In many New London County homes — especially older properties — uncontrolled air leakage is a major cause of drafts, uneven temperatures, and high heating bills.

    Our team carefully identifies and seals common problem areas, including:

    Attic penetrations and top plates

    Rim joists and basement gaps

    Window and door framing transitions

    Plumbing and electrical penetrations

    Duct and vent openings

    By reducing uncontrolled airflow, we help create a more stable and efficient indoor environment.

    Air Sealing Materials & Techniques

    Depending on the location and size of the air leak, we use a combination of professional-grade materials, including:

    High-performance caulks for sealing stationary cracks and seams

    Weatherstripping systems for doors and operable windows

    Expanding foam sealants for larger gaps around pipes and wiring

    Rigid foam board to block airflow in attics and crawl spaces

    Air barrier tapes and sealants to reinforce building transitions

    Proper flashing techniques around window and door openings

    Each application is selected based on building conditions and long-term durability.

    Benefits of Professional Air Sealing

    Improved Indoor Comfort

    Reducing air leaks eliminates drafts and helps maintain consistent room temperatures throughout the year.

    Moisture Management

    Uncontrolled airflow often carries moisture into attics and wall cavities. Air sealing helps reduce condensation risks and supports mold prevention.

    Lower Energy Costs

    By limiting heat loss in winter and unwanted heat gain in summer, air sealing reduces strain on heating and cooling systems.

    Better Indoor Air Quality

    Sealing gaps helps prevent dust, allergens, and outdoor pollutants from entering living spaces.

    Why Air Sealing Matters in New London County

    Coastal winds and seasonal temperature swings in southeastern Connecticut can amplify air leakage problems. Proper air sealing ensures insulation performs effectively and protects your home’s long-term efficiency.

  • Rockwool Thermal Insulation

    Rockwool insulation, also known as stone wool or mineral wool, is a dense insulation material made from natural stone and recycled materials. It is manufactured by heating raw materials to extremely high temperatures and forming them into durable, fibrous batts.

    Because of its density and resilience, rockwool is often used in applications where thermal performance, fire resistance, and sound control are priorities.

    Strong Thermal Performance

    Rockwool slows heat transfer by trapping air within its tightly woven fiber structure. This helps stabilize indoor temperatures during Connecticut’s cold winters and humid summers.

    Superior Sound Control

    The dense composition of rockwool insulation makes it highly effective at reducing sound transmission between rooms and floors. It is commonly used in interior walls, ceilings, and home theaters where noise control is important.

    Fire Resistance

    Rockwool is non-combustible and can withstand high temperatures without contributing to flame spread. This makes it a strong option for fire-rated wall assemblies and areas where added fire resistance is desired.

    Moisture & Mold Resistance

    Unlike some insulation materials, rockwool does not readily absorb water. Its structure allows it to maintain performance even in areas prone to humidity, helping reduce the risk of mold growth.

    Long-Term Durability

    Rockwool insulation resists sagging and settling over time, maintaining its thermal and acoustic properties for decades when properly installed.

    Common Applications

    Rockwool insulation is frequently used for:

    Interior wall sound control

    Basement and foundation insulation

    Fire-rated wall assemblies

    Floor systems between living spaces

    Mechanical room and utility space insulation

    In homes throughout New London County, it is often selected for areas requiring both sound reduction and durable thermal performance.
