Frequently Asked Questions

For an attic in Evanston, blown-in cellulose or fiberglass is generally the most effective and cost-efficient choice, especially when reaching an R-value of R-49 to R-60. These materials fill irregular spaces completely, minimizing thermal bridging, which is important for preventing heat loss through the roof during cold Evanston winters. Western Insulation Company also prioritizes air sealing all penetrations like electrical wires and plumbing stacks before blowing in insulation, because stopping air leaks is just as important as the insulation itself for optimal performance.
Evanston homes often need new Insulation when homeowners notice specific signs of energy loss. Homeowners in Evanston, IL can tell if their home needs new Insulation by noticing uneven temperatures between rooms, high energy bills compared to similar homes, or drafts near walls and windows. Western Insulation Company sees these issues often during Insulation projects in the local area. Other signs of failing Insulation include ice dams forming on your roof during winter, which indicates heat escaping from your attic, or a furnace that runs constantly to maintain temperature during cold winter months. When you need to check your Insulation, Western Insulation Company can perform a thorough energy audit, including thermal imaging, to precisely identify areas of heat loss or gain.
Dense-pack cellulose insulation is a very effective method where recycled paper fibers are blown into enclosed wall cavities at a high density, typically 3.5 to 4.0 pounds per cubic foot. This technique is excellent for old Evanston homes, especially those with plaster walls, because it fills voids completely, eliminating convection currents within the wall and significantly improving sound dampening. Western Insulation Company provides Dense-pack cellulose insulation services for homes in Evanston, Illinois. This is an ideal solution for upgrading insulation in existing walls without requiring extensive demolition, which preserves the historic character of many Evanston properties while dramatically improving energy efficiency.
The process for insulating exterior walls in an existing Evanston house typically involves drilling small, strategically placed holes from the exterior or interior, then injecting dense-pack cellulose or foam insulation into the wall cavities. When working from the exterior, Western Insulation Company carefully removes a small section of siding, drills the holes, injects the material, and then plugs the holes and replaces the siding to match the existing finish. This method ensures thorough coverage and minimal disruption, which means you get improved thermal performance without major renovations, addressing common drafts in older Evanston homes.
Western Insulation Company finds that new Insulation, specifically Dense-Pack Cellulose Insulation or Mineral Wool Insulation, helps greatly with soundproofing in Evanston, IL, by adding mass and absorbing sound waves. Dense-Pack Cellulose Insulation placed in wall cavities improves thermal performance and also reduces airborne sound transmission from outside noise, such as traffic on Sheridan Road or general neighborhood activity in Evanston, IL. For interior walls, installing batt Insulation like Mineral Wool Insulation between studs dampens sound transfer between rooms. Western Insulation Company makes sure this creates a quieter living environment throughout your home in Evanston, IL.
