Both the polycarbonate composite matrix helmets and the fiberglass/Kevlar helmets comply with the exact same standards-DOT and Snell. These are "pass-fail" standards and do not reflect any continuum or graduated level of compliance. The VX-14 and VX-17 dirt helmets also comply with both standards. No one can tell (or guarantee) you one will be any safer than another in an accident.

Fiberglass air conditioner furnace filters are designed only to capture large particles and to protect your heating and air conditioning system; they do nothing to remove smaller particles like many allergens. These types of air conditioner furnace filters also have either no Merv rating assigned to them or in some instances, have a MERV rating of from 1 to 4. See similar questions...

Polycarbonate is the other material commonly used in domed skylights. Polycarbonate is used in applications where impact resistance is a requirement. It is the material used in our Miami-Dade Approved Hurricane Impact Skylights. It is even popular in areas that may be prone to Hail Damage. Polycarbonate can be formed just as easily as acrylic.

All Florida Building Code approved hurricane protection provides good protection and all of the Florida Building Code approved hurricane protection must pass the tests required by the State of Florida. ArmorPanel? passed the exact same tests as steel, aluminum and polycarbonate panels. That said, it is subjective to say that one protection is 'better' than the other but we believe that ArmorPanel? provides excellent protection and a host of features not offered with 'hard shell' solutions.

Solexx greenhouses are made with polyethylene. Polyethylene is much more flexible and is easy to cut to any size. Polycarbonate panels tend to be thicker, but have about the same insulation factor as polyethylene. Both materials diffuse light, but polycarbonate diffuses less (because it is more transparent), making the greenhouses much hotter in the summer. Polyethylene is very easy to clean and will not scratch like polycarbonate. See similar questions...

No, please don't. We do not know how long your neck is, how big your neck is, how big your shoulders are, where your belts ride on your shoulders, how your seat is shaped or the angle of your seat. Besides, Isaac® doesn't care since it doesn't really touch the body. That's why there aren't different sizes. You may as well install the mounts youself, and save the time and expense of round-trip shipping. (Go to top) See similar questions...

Polycarbonate lens material is so tough that you can hit it with a hammer and it won't shatter. Ordinary polarizing lenses are made out of plastic (CR-39), and are not shatter resistant. In addition, polycarbonate lenses absorb harmful UV radiations. See similar questions...

Fiberglass is a cloth made out of thin glass threads. It is used to reinforce plastics and other materials. FIBERLAND uses fiberglass to manufacture all our plastic products. Therefore the correct name for the material we use is FRP (Fiberglass Reinforced Plastic), although our products are said to be made of fiberglass. See similar questions...

Fiberglass offers a very strong, thick and tough lining and will also not be prone to algae infestation. The draw-backs are: Fiberglass does not "bond" or penetrate the substrate and is more like a shell in your existing pool. This means that should water accumulate between the lining and the concrete or cement substrate, problems can occur with large bubbles forming. Cracking may occur and your pool might start leaking.

No two heads are the same, which is why Orthomerica created different headband designs. Each is constructed differently to direct head growth where needed. For instance, the basic STARband design treats moderate to severe plagiocephaly and brachycephaly, while the bi-valved STARlight is for babies with severe scaphocephaly. The cranial specialist will determine which headband is needed. See similar questions...

There is no fair answer to this question. The DOC Band, STARband and several helmet styles have been proven to work. The best thing for you to do to answer this question is to talk to your closest Cranial Technologies clinic, contact Orthomerica, and talk to your local helmet provider. See similar questions...

If you have worked with helmets before it is pretty simple. If you have not, you will need more patience than effort. All mounting hardware is included, and the instructions are straight forward. All racers are good mechanics, so give yourself about an hour or two. Look on the bright side: You only have to do it once. The adhesive mounting kit we offer is easier and faster than using nuts and bolts. See similar questions...

Everything but the main body shell of the FIA is done in-house. We built all the molds from our own plugs. All door pieces, hood and trunk lid, and inner panels are hand laid at E.R.A. Mating of the inner panels to the outside skin is also done in-house. We don't use ordinary polyester resin, either. We spend a little extra money to get low-shrink tooling resin for better long term dimensional stability. Dealer information E.R.A. has a very limited network of dealers. See similar questions...
