"Was told Pad was not working properly for before and after pictures. I must trust that US Insulation stands behind their name. Once the snow falls it will be apparent of the quality of their work."

"Do NOT Hire this Company. Poor job. Ineffective insulation. No reduction in Winter Heating costs and No Reduction in Summer Cooling costs. They use foam insulation that Degradeds & Shrinks & Crumbles. Extremely Poor, to Non-Existant Warranty. There are other companies over and Back up their Product & workmanship with a Lifetime Warranty. Spoke wirh the Owner of the Philadelphia Office & the Main Headquarters. Owner told me he will call me and get back to me after he returned from Europe from his son's soccer tryouts for a European team. I never heard back from him"

"We ordered our large front window (including 2 side windows) back in November 1923. They said it would be 6-8 weeks and that was fine with us as Christmas was around the corner. Come January 2024 we hadn’t heard any updates so my husband called them to check the status. They said it hadn’t been delivered yet (built in Ohio). In February, hubby called again and they reported the side windows had but the center one couldn’t be found… . We agreed to go ahead with the side window install mid February. They came and did a nice job, but they had to complete the frame in with new Quarter Round (plain wood color)! They left. The next report : it was coming in end of that week . Didn’t happen. Finally end of February it arrived from warehouse. Today it got installed on March 4th!! In the meantime my husband said for all the mix up in dates and install dates wonder if they would accept a deal? They agreed to paint the new Quarter Round instead of a $50 discount. And we agreed on White to match the Framing on window. The guys who came to finish/complete last install were very curtious and cleaned up after everything was done . We are very pleased with the work they performed and really love the Triple Pane windows. Looking to lower our energy bill as the last windows had no insulation!"

Energy Efficiency Auditing questions, answered by experts

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.

Fans reduce peak cooling loads, lower air conditioning energy expenses by expediting heat exit, and enhance natural airflow throughout the home.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.
