Thermally-tempered glass is made by placing a piece of regular glass in an oven, bringing it almost to the melting point and then chilling it rapidly.
When shattered, the glass breaks into relatively harmless chunks resembling rock salt, free of sharp edges. Fully tempered glass is three to five times stronger than glass that has not been tempered and is five times as resistant to heat. Once the glass has been tempered, it cannot be cut or processed further. Tempered glass can be any thickness, and almost any type or color glass may be tempered except wired glass or glass with a deep patterned surface.
Tempered glass is a logical choice for installation along passageways, in entrance doors and adjacent panels. Building codes in many jurisdictions now require this type of glass in areas or locations where individuals are likely to bump into it. Laminated glass is well-suited for installation in street-level windows or displays, doorways, and other access areas where security is necessary.
It is composed of two sheets of ordinary glass bonded to an intervening layer or layers of resilient plastic material, typically PVB polyvinylbutyral. When laminated glass is broken, it may crack and break, but the pieces of glass tend to adhere to the plastic material.
If a hole is produced, the edges are likely to be jagged, as with ordinary glass. Laminated glass helps protect against the "smash and grab" criminal. A criminal who encounters this type of glass cannot simply hammer his way through it within a few seconds and will be inclined to move to an easier target. However, given enough time, a burglar will be able to defeat laminated glass.
For extreme situations where you need serious protection, you can install bullet-resistant glass. However, the cost is high as this is one of the most expensive window protective measures available. The thicker the glass, the more protection. The various thicknesses can be certified under Underwriters Laboratories, Inc.
Plastic glazing material can be divided into two general categories - acrylic and polycarbonate. Both are available in a variety of patterns and in a wide range of transparent, translucent, and opaque tints, as well as in clear form.
Acrylic is more transparent than polycarbonate, while polycarbonate possesses outstanding strength against impact. Due to the way acrylic and polycarbonate expand and contract in changing temperatures, both must be installed by a professional.
Both are prone to scratching , so exercise extreme care when cleaning these surfaces. It is available in varying thicknesses and it has much more impact resistance than double-strength window glass. It is not only safer than glass due to its breakage resistance but, when it is broken, it does not shatter into small slivers with sharp edges, but breaks into comparatively large, dull-edged pieces.
Polycarbonate is almost unbreakable. It has times the impact resistance of glass and 20 to 30 times the impact strength of acrylic. It is expensive -- about four times the price of standard glass. But if your property is repeatedly being vandalized or broken into, it may well be worth the additional cost. Source: wisegeek. Polycarbonate is an ideal choice for small windows like those found in doors. Polycarbonate should be professionally installed. If you hit it with a sledge hammer it probably won't break, but if it's not installed properly, the whole window is likely to get knocked right out of the window frame.
It has a slight blue or gray tint, and so it is less clear than other types of glazing and shows some distortion. This type of material is reported to be less weather resistant than glass or acrylic, but can be expected to remain serviceable and attractive for seven years or more in outside installations. Check your local fire code before installing polycarbonate in your bedroom windows to be sure you are not in violation. While there are many steps you can take to reinforce your windows and keep them well-protected from intruders, the methods above are primarily delay tactics to buy time for police to arrive.
Self-installed home security is great when you're on a budget but you or a family member has a few spare minutes during the day to get it set up. Alternatively, you can opt for a professional installation if you have a complex system with many components which will take longer to install.

But groundwater is naturally attracted to these wells, even if they are covered, so the proper steps must be taken to prevent this water from pooling up and possibly leaking into your basement or breaking the windows.
A proper drainage system and a sturdy, correct-fitting cover are a necessity in keeping your basement dry. But you should also make sure you have sturdy, metal wells that are attached securely to your foundation. Most basement windows are installed in window wells, which are known to naturally attract groundwater. So it is necessary to include well drains with any window well you may have. These drains are tied into the home's drainage system and covered with a cap to keep debris from getting into the drain and clogging it.
It is IMPORTANT to make sure this cap is not covered with debris and keeping the well drain from working properly, and the best way to do that is to have a quality cover on your window well.
If your well is not properly fitted with a drain or it is clogged with leaves, when it rains water will start to pool up next to the foundation and could force its way into your basement through any cracks in the wall or weak spots around the window frame. Sometimes we've seen the water build up enough pressure to eventually break through the window and cause all the water to go flooding into the basement, causing a huge mess and a costly repair for the homeowner.
