1/8" laminated UV filtering/safety glass that eliminates 99.5% of UV rays from impacting the finish on your instruments.
We often get asked when this option is recommended and our answer is there are three to four situations where this upgrade probably makes sense.
1.) Your instruments have a nitrocellulose finish which is prone to cracking with excess UV ray exposure.
2.) Your instruments have a white spruce top which is prone to yellowing with excess UV ray exposure.
3.) You have small children who you'd like to protect shards of glass should the unexpected yet possible fall into the ClimaStand or ClimaCase should occur.
4.) You want some additional theft protection.
To understand the options and benefits of UV protection, you must understand the science of sunlight.
Radiation from the sun contains ultraviolet, visible, and infrared light. These three spectrums get defined by their wavelengths and measured in nanometers. One nano-meter equals one-billionth of a meter.
Visible light runs from 400-to-800 nanometers in wavelength. Any distortion of this spectrum will diminish or alter the appearance of an instrument. Outside of that range, it's necessary to block as much solar radiation as possible to preserve your instruments.
Scientists define ultraviolet radiation as light in wavelengths of 295-to-380 nanometers. Invisible, it can be blocked completely without any detectable difference in lighting.
An advanced UV glass coating that virtually eliminates UV radiation with minimal effect on the visible light spectrum and becomes a most effective weapon against instrument finish damage. The use of UV glass, in combination with humidity and temperature controls, offers powerful protection.
The UV filtering glass we use is laminated and naturally doubles as safety glass because it's actually two pieces of normal glass with a un-noticeable thin layer of UV filtering material sandwiched in between. This lamination is identical to what is used in car windshields. The most commonly used interlayer is polyvinyl butyral (PVB).
According to one study, this type of laminated glass completely blocks both UVA and UVB radiation. Laminated glass is less common in picture framing due to its considerable weight and cost; however, we offer it in our all products containing glass because of the two factors of UV protection and the safety factor associated with this material.
Each piece is cut precisely to be approximately 1/16" shy of the door frame on the top, sides, and bottom.
The installation begins with a bead of clear silcone along the entire door frame. The piece of UV Blocking/Safety Glass is laid onto the door frame and allowed to set up for 24 hours.
Next, a top bead is installed between the gap of the glass and the door frame before a matching wood strip is installed to conceal the gap and give a professional finished look.
