Frequently Asked Questions

Q: I can feel a cold draft through my window. Can Window Inserts help with that?
A: Yes, our inserts are perfect for that. Our claim to fame is that we reduce air infiltration to approximately .03cfm. If you stop air infiltration then you stop drafts. So by putting our window on the inside, we don’t care how ineffective your existing window is; it’s behind us. The putty lines, the window weights, the shrinkage that’s built into your existing window from its lifespan all contribute to drafty windows. Even replacement windows suffer from air leaks. So by utilizing our magnetic attachment system, we are basically creating a refrigerator door-like seal for your window, which is easily removed if necessary.

Q: I have central air in my home, do window inserts help keep the house cool in the summer?
A: Our product is highly effective in hot and cold climates. Although the greatest payback is to utilize them in all seasons, you will see an even greater return in the summer months than in the winter months. It’s actually more expensive to take heat out of the air for air conditioning purposes than to introduce warm air for heating purposes. We also offer actual tinted acrylic (not a film) for additional sun control.

Q: Why do you use acrylic vs. glass?
A: The glass industry would have you believe that acrylic is the worst thing you could possibly use for any type of window. This is simply not true. We are using acrylic on the interior of the building where it is not exposed to the elements. Acrylic has higher insulation properties than glass, it can be 1/3 the weight of glass and is 17x stronger than glass of equal thickness. Replacement window manufacturers are now recognizing acrylic’s benefits as an insulator. In fact, replacement window manufacturers are implementing acrylic sandwiched between two pieces of glass to form a triple pane window.

Q: What if I want to open my window and let in some fresh air?
A: Window Inserts from Window Efficiency Works are as easily removed as they are attached. Because of our unique magnetic attachment system, we do not need special screws, clips or fasteners to keep it in place. Fresh air ventilation can be achieved by either removing a full size panel from the opening or just the lower window insert in our 2-panel option. A popular choice among those clients who frequently open their primary windows.

The Climate Seal™ system is also egress/ingress approved for most building fire codes. Egress/Ingress simply means that occupants trying to escape due to a fire or another emergency will not be impeded by our windows due to its unique magnetic attachment system. It also means that firefighters would easily be able to access the building through the windows with the same ease by pushing the panels in and releasing the Climate Seal’s™ magnetic hold.

Q: I live right near a major highway and sometimes all I can hear are the trucks going by. Will window inserts reduce my noise problems when I’m in the house?
A: The Acoustical Series offers an excellent noise abatement solution for your existing window problem. Because our molding incorporates a ‘bellowed’ system we are not creating a drum effect, which amplifies noise transmittance. And by utilizing acrylic as our glazing and a dead air space between the primary window and our panel, we are able to greatly muffle a wide spectrum of noise pollution. Some of these examples include: air-craft, automobile traffic, trains etc… Our standard thermal series 1/8th inch acrylic; has been tested to effectively reduce sound transmission by 46-55%. We also manufacture a panel specifically designed for noise abatement. Results have shown a 65-70% noise reduction within the existing window cavity.

Q: Because you use acrylic as your glazing can it scratch, cloud or yellow?
A: This is a very loaded question, which is not easily answered. Acrylic does have the ability to scratch if it is abused and not cared for properly. Acrylic is a softer glazing material than glass, which can also scratch. That is why we recommend Brillianize cleaner, which is recommended for all reflective surfaces including glass. We also recommend soft re-usable cloths such as a Wypall rather than paper towels, which are abrasive. With respects to clouding and yellowing, acrylic is often confused with polycarbonate, which is also in the plastic glazing family. Both have their benefits as polycarbonate is virtually unbreakable and is a good option for security purposes. The difference between acrylic and polycarbonate is that acrylic filters the sun’s u/v rays while standard polycarbonate absorbs the sun’s u/v rays. Because of this, standard polycarbonate will yellow quickly over time, while acrylic exhibits excellent resistance to discoloration when exposed to the sun’s u/v rays.

Q: What is Climate Seal™
A: Climate Seal™ is a nationally recognized brand of Magnetically Sealed Interior Storm Windows. Also known as Window Inserts or Window Panels, Climate Seal™ is a window retrofit system designed to stop air infiltration, provide increased thermal insulation, abate excess noise and sounds, filter harmful UV rays, and appear nearly invisible when installed on the interior of your existing windows. Window Efficiency Works is proud to offer Climate Seal™ window inserts as an authorized dealer and fabricator.

Q: What is so different or special about Climate Seals’™ molding?
A: molding is definitely a unique product to Climate Seal™. In fact, there have been many attempts to produce a similar version of this molding because of its superior performance. Climate Seal however, has perfected a molding based on a concept from the early 1970’s that was designed to reduce fuel consumption during the energy crisis. Our molding uses an exterior grade PVC with a U/V stabilizer, has the strongest magnetic pull in the industry and our unique bellows design eliminates the need for additional attachment clips or screws. The molding is a trademark of Climate Seal Inc. and there is a patent pending on the product. It is unquestionably the most superior product available for an interior magnetic insulating window system!

Q: Are Window Inserts eligible for federal tax rebates or incentives?
A: At this time the Climate Seal™ window inserts available through Window Efficiency Works are not known to be eligible for tax rebates or incentives through the federal government. We will be monitoring for any changes to this status. There may be eligibility for certain state government or local assistance programs such as those offered by local governments, non-profit organizations, and gas and electric companies. If you find a program for which our window inserts are eligible, we would love to hear from you.
