"Atlas home energy solutions did an outstanding job from start to finish. They were professional, knowledgeable, courteous and easy to work with. All the crew members Ben Mott (was very knowledgeable, did the home energy audit, followed up with competitive quotes, which was adjusted to accommodate my request, offered BGE rebates upfront, patient and friendly to attend my calls and answer all the questions), Zam (Crew leader who did the exhaust fan installation), Tun (Crew leader who did an outstanding job to insulate the attic and basement), David (Crew leader who did duct cleaning and Aeroseal) were phenomenal and did an outstanding job. The end result is a day and night difference before and after the work and my BGE bill last month went down by more than $100 which is a huge cost saver. The HVAC does not run that much these days and the temperature is pretty even across the 30-year townhouse. I highly recommend Atlas home energy solutions for home energy audit and improvements."

"It was fine. They were prompt and gave me an estimate on the spot when they did the inspection. They came the next week or several days after and put in everything. I'll give them 5 stars but they never get back to me until now. It depends if depends if I'm going to use them again if they get back at me and answer all the questions that I have."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Frederick, MD

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
