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.
