Energy Efficient Security Glazing for Cold and Heat Reduction
DefenseLite doubles as an energy glazing solution and security shield that installs over existing windows and door glass to create a powerful layer of protection from both criminals and the elements. Unlike other energy efficient glazing solutions, there’s no need for a heat-reflective coating. DefenseLite’s polycarbonate shield acts as an impressive storm window and can improve the energy efficiency of existing window and door glass by up to 30-50% all on its own.

DefenseLite System Provides Added Noise Reduction
DefenseLite is mounted either on the exterior or interior of your current glass by certified installers, creating an airspace between the primary glass and the DefenseLite clear shield. This airspace provides significant window noise reduction to stop noise pollution. There’s no need to install noise reduction windows when DefenseLite can reduce street noise by up to 40%.
Noise Reduction SolutionsEnergy Efficient Security Glazing with UV Protection
Utilizing a proprietary UV protective coating for windows and doors, DefenseLite energy glazing capabilities protect you and your employees’ or students’ skin and eyes from dangerous UV exposure while also protecting your furniture and product displays from fading. These UV blocking windows improve energy efficiency without hindering natural light and the appearance of the school or office building.

Comfort & Energy FAQs
The most energy-efficient glass isn’t glass, it’s a plastic called polycarbonate. Since polycarbonate has similar visibility capabilities to glass, it is often used to increase the energy efficiency of window and door glass. Installing polycarbonate energy glazing like DefenseLite can improve the energy efficiency of the existing glass by 30-50%.
The most energy-efficient double glazing will have gas-like argon between the panes. This gas helps to slow and decrease temperature transfer, keeping the inside of your home comfortable no matter the season.
Many energy-efficient windows use Low-emissivity (Low-E) glass which has a thin coating of metal oxide on one of the interior surfaces of the glass. This coating helps to reflect heat and sunlight into the home to keep it warm.
DefenseLite acts as double glazing for existing window and door glass since it is a retrofit solution installed on the outside of your glass. Much like double-pane windows, DefenseLite also institutes the use of gas in the air gap to slow temperature transfer and can be installed with a Low-E film to improve energy efficiency.
Glazing is a term used to describe the glass in a window whether it is single, double, or triple glazed. So, energy glazing refers to the energy-efficient window glass. The main goal of these types of windows is to slow temperature transfer so that you can use your heating and cooling systems less.
Many energy-efficient glazing solutions incorporate double or triple panes, a gas between the panes, and a low-emissivity coating. All of these techniques can improve the overall energy efficiency of the glass.
- Check windows for air leaks.
- Caulk and weatherstrip to prevent air leaks.
- Add energy-efficient window films.
- Install window treatments like shades or drapes.
- Use a window insulator kit to keep heat in and cold out.
- Add exterior shading like awnings.
- Replace windows with an energy efficient alternative.
- Install energy efficient secondary glazing.
If you’re looking to completely replace your windows, there are several factors to consider that will help you choose the most energy-efficient option. The best energy-efficient windows will be double or triple panes with argon between the panes. U-factor is how the energy efficiency of windows is measured, so you should look for windows with a U-factor of less than 0.30.
An alternative to replacing all of your windows is to install DefenseLite over your existing glass. DefenseLite is primarily crafted of polycarbonate which gives it an advantage over conventional heat reflective glass products because it is much thicker. DefenseLite’s retrofit film options provide for impressive solar heat gain reduction and sun control. With extensive insulation and UV and infrared blocking polycarbonate, DefenseLite provides thermal efficiency and safety in one.
Replacing all of your windows can be a costly project since energy-efficient windows are more expensive. You can expect to pay around $300-$1,000 per window plus labor costs. However, you will save money on your energy bills over time, so this amount should also be factored into the overall cost.

“Recently we had a torch attack on the side door at our Patagonia Portland Store (there have been two now). And last week we had a cinderblock attack on the same set of doors. There are no broken door glass, the doors were not damaged, and no intrusions into our store. Without DefenseLite, the damage to the door glass and doors would have been in the 10K range minimum. Then you have the amount of product that could have been taken out of our store. And then (a harder matrix to measure) store moral and store appearances would have most likely have suffered. Bottom line, DefenseLite works again!“

“While there are numerous aspects to any comprehensive security program, if you are able to make the windows of a facility difficult or impossible to breach, you can significantly enhance the overall security of the site. Many institutions take actions to secure their facilities without considering the “why” behind those actions. The best security plans are rooted in security principles that allow you to gain time during an emergency situation, and keep a threatening person at a distance. This is exactly why we utilized DefenseLite and BulletShield for our more vulnerable clientele, worldwide. Having worked on numerous and complicated security projects all over the world we have also experienced the value of having a high quality partner to properly install these items. Jeff Franson and his team have always done a stellar job, going above and beyond, and have ensured that the windows at our sites have the highest level of security features.”

“I just wanted to take a minute to let you know that we recently had an attempted break in, the key word here is (attempted). Around 5:30 AM 3 individuals pulled up to the store, got out of a car, wearing masks and carrying bats and bricks. One started throwing a landscaping brick (~10 pounds) at the glass door protected by DefenseLite and the rock just bounced off, the other two went to work on one of the windows with the bats. The bats had little effect on the DefenseLite. After about 5 minutes of repeatedly throwing the brick at the door the glass behind the DefenseLite broke, but the DefenseLite stayed intact. The three spent a total of 8 and a half minutes beating on the Defense with rock and bats and still did not get in. I am 100% confident had I not chosen to put the DefenseLite they would have gotten it and gotten away with countless guns and I would have been dealing with the ATF and State Police for weeks if not longer and there would be a lot of illegal guns on the street. DefenseLite is hands down the best means of keeping bad people out of your store.“

“As a security and protective design and engineering consultant for 45 years, and after having participated in reviewing, analyzing, testing and subsequently specifying many different force protection products for clients with extreme security concerns, I would strongly advise those in similar positions to consider the products sold under the “DefenseLite” brand name, and fabricated, furnished and installed by Impact Security. We have submitted their products to personal attacks by our security specialists and been engaged in having their products tested under live firing range conditions by elite law enforcement agencies for ballistic resistance and forced entry and can attest to their efficacy and value.”

“DefenseLite recently completed a very complex lobby project for us which entailed a specialized design with multiple pieces and required a challenging installation. We could not be happier. The project was a grand success and the DefenseLite management as well as installers were the utmost professionals demonstrating genuine care and customer service. Their technical knowledge is superb. We felt very taken care of as updates and good communication with us were continually provided. Thanks!”
