DefenseLite Product FAQs

What is DefenseLite?

DefenseLite is the ‘flexible’ and ‘vented’ overglaze security solution. A patented technology, DefenseLite is a ‘clear security shield’ that installs over existing window and door glazing creating a layer of protection designed to ‘keep the bad guys out’. DefenseLite shields are 250 times stronger than glass, nearly invisible once installed and a long-term forced-entry solution that works. Utilizing proprietary high-optic UV coated polycarbonate shields, patented vented extrusions, multi-layer thin films and tough structural adhesives and flexible security tipped anchors, DefenseLite is an engineered system that combines the best of materials science with an easy to retrofit installed solution. 

What makes DefenseLite a superior ‘overglaze’ security solution for windows and door glass?

Better quality components and superior mechanical and thermal engineering separates DefenseLite from less expensive competitor systems. DefenseLite is a patented ‘flexible’ and ‘vented’ overglaze system that provides for unmatched resilience under robust attack.  Our patent pending venting system protects customers from longer-term condensation and moisture related issues inherent in hermetically sealed, non-vented, field installed overglaze systems.  

Why a ‘vented’ overglaze system is critical for the long-term system integrity?

In field conditions, it is not advisable to hermetically seal the air space between over-glazing and the prime window. Why? It won’t workThe only time ‘sealed airspaces’ work is in factory sealed, dehydrated insulating glass units. These ‘sealed IG units’ are built in controlled, factory conditions. To address this properly, DefesneLite overglaze systems utilize our patent pending ‘engineered ventilation’ behind the field installed overglaze. 

This passive design is ’tuned’ for the local climate conditions and usage. The DefenseLite ‘engineered venting’ system basically dries out the air behind the overglaze on an ongoing, dynamic basis leading to a low likelihood of longer-term condensation or moisture issues. Less expensive, non-vented overglaze systems will experience moisture and condensation issues once the desiccant entombed in the framing system becomes saturated leading to an expensive fix for the building owner down the road. 

What is ‘Engineered Ventilation’ and why is this critical to system integrity?

Each DefenseLite system is engineered for the local climate and usage so that the airspace behind the overglaze is ventilated to the adjacent space that is predicted to be drier at the most critical times of the year. Then, a precisely calibrated array of passive vents, based upon the premise of Boyle’s Law, are deployed to make the magic happen, keeping your overglaze system condensation free for the long-term.  

Will ‘desiccant only’ systems work to mitigate moisture and condensation over the long term?

 No. Field installed overglaze systems create a new airspace that requires airflow to mitigate condensation buildup in the newly created void. Without proper airflow, moisture will build up and create problems for the customer in many climate zones over time. ‘Desiccant only’ moisture control systems will eventually fail to control the condensation once the desiccant is exhausted and overwhelmed leading to foggy, unattractive windows and doors that will be very expensive to fix down the road.  

Why a ‘flexible’ system is important for maximum protection from forced entry?

Each component in a DefenseLite system is designed to ‘flex’ under significant force from robust attack. As the DefenseLite system ‘flexes’ while absorbing impact, energy is dissipated evenly throughout the overglaze providing for increased performance over competitor’s less expensive, rigid and fixed designs. DefenseLite overglazing is like a Zen Master. It doesn’t attempt to ward off intruders like a brick wall. Instead, it flexes and absorbs the impact, dissipating the forces harmlessly out to the edges of the panel. Without breaking, tearing or detachment.  Bad guys get frustrated with our flexible resistance and soon move on to a more vulnerable victim.  

How does DefenseLite control the “pillowing” effect prevalent in other plastic glazing solutions?

‘Pillowing’, or ‘bowing’ prevalent in some plastic glazing creates unsightly distortion and ‘fun house’ mirror effects. Pillowing occurs when thermal (solar heat) buildup creates a condition where the plastic glazing expands, or ‘pillows out’ due to increased barometric air pressure and thermal expansion.  The patent pending “Moore” venting system engineered into DefenseLite allows for dynamic airflow from the newly created airspace to an open space alleviating the increased air pressure caused by solar heat gain. The DefenseLite overglaze is flexible and super strong. Like all polycarbonate, the sheet tends to grow when it gets warmer.  When plastic over-glaze “pillows” within a fixed rigid frame, it is because it is trying to grow – but it can’t – so it bulges out instead. DefenseLite’s engineered ventilation keeps the panel ‘cooler’ so it grows less, eliminates the pressure and allows the panel to float at all edges. Result: No unsightly bulge!

How are DefenseLite polycarbonates unique from commercial polycarbonate sheets available to everyone else?

Impact Security has a special relationship and a unique specification for its polycarbonate sheets used to make the DefenseLite shields.  Manufactured in the US by the leading manufacturer of plastic substates in the world, Plaskolite, DefenseLite’s proprietary polycarbonate specification guarantees our customers enjoy the most optically clear, black spec- free, low-distortion, UV capped sheets available anywhere in the world.  

How does DefenseLite maintain the integrity of the polycarbonate face? Will it scratch?

DefenseLite utilizes both abrasion resistant factory applied coatings and retrofit UV impregnated sacrificial thin-film laminates to protect the surface of the DefenseLite panel from scratching and degradation. 

Will the DefenseLite polycarbonate yellow from sun exposure?

DefenseLite polycarbonate sheets are “UV capped” and warranted against yellowing for a minimum of 7 years. Many DefenseLite systems incorporate a secondary layer of UV protection with the application of a thin film laminate primarily designed for sacrificial surface protection. 

What are the largest openings that can be covered with DefenseLite without a seam?

DefenseLite offers the largest single sheet high optic UV coated polycarbonate in the world.  Made to our exacting and unique Plaskolite specification for optical clarity and durability, our single sheets can be as large as 156” x 96” and perfect for oversized windows found in urban retail centers and showrooms across the US. 

How is DefenseLite Installed?

DefenseLite is installed over your existing window and door glazing by certified dealer/installers. Mounted and anchored onto the exterior or interior of your existing glazing, DefenseLite affixes to your window or door frames creating an airspace between the primary glass and the DefenseLite clear shield. A weather sealed and vented system that mitigates any ‘pillowing’ or condensation buildup, DefenseLite is custom made for every opening and designed to blend into the existing framing for a clean, finished look.  DefenseLite is nearly invisible upon a completed installation, has no moving parts or long-term serviceable items. 

What are the benefits of DefenseLite other than security?
