Frequently Asked Questions

The size you are working with.

The two sizes to know are the “rough opening” and the “glass area”

The rough opening is the size of the hole in the wall.

The rough opening has three dimensions Height, Width, Depth

The size on our site when ordering a framed unit is the “rough opening” size

The “glass area” size will be three inches less in height and width than the rough opening size.

A 15” x 15” rough opening size will have a 12” x 12” glass area, giving you a 12” x 12” area to work with for your lightpath.

If you're ordering just the glass without the frame, you will receive the exact size of glass that you order.

The thicker the glass, the better the sound insulation (STC) will be in the studio. STC is a rating to calculate how much soundproofing there will be.

A Single Glazed 6mm Port Window has an estimated STC of 31

A Single Glazed 10mm Port Window has an estimated STC of 34, and a Dual Glazed Port Window has an estimated STC of 40.

The thicker the glass, the better the sound insulation (STC) will be in the studio. STC is a rating to calculate how much soundproofing there will be. A Single Glazed 6mm Port Window has a STC of 31,

A Single Glazed 10mm Port Window has a STC of 34 and a Dual Glazed Port Window has a STC of 40.

Single Glazed Port Window has 1 piece of glass in the frame.

A Dual Glazed Port Window has 2 pieces of glass in the frame. Dual Glazed offers the most superior sound insulation properties.

The dual glazed has two different thicknesses of glass that vibrate at different harmonic rates and the result is called noise canceling in between the 2 sheets of glass.

If there is machine noise, projection room noises, or fan noises a Dual Glazed Port Window will buffer the noises from leaking through to the audience. This will help create a better and more professional movie experience.

Our Dual Glazed Port Windows are found in the top movie studios, recording studios, and professional theatre chains globally.

There are different ways to install the framed unit depending on your project. Most projects will be installing the frame onto a 2" x 4" where the frame will be slid in to your opening. You can use a sealant on the edges, but it is imperative you do not get any of the sealant on the glass!

We ask for up to 10 business days for production and offer different shipping times which you choose at checkout. We will ship as soon as it is completed (often times this is before 10 days).

The size you need for your project will depend on the following information: Technological details needed: Projector light path on glass- measure how far away you are planning to place your projector from the glass.

Use throw and aspect ratio as guidelines for your specific setup to determine the minimum size needed to clear your Lightpath.

If you will be buying a framed unit – add 5” to the minimum size needed to clear the light path – 3” will be used for framing, 2” will be used as a cushion in the event you need to adjust/recalibrate your image.

Architectural Details Needed: Pre-existing frame/hole in the wall: Determine if you can just replace the glass or if you will need a larger area frame. If you just need to upgrade the glass you have (either not anti-reflective or the current glass is damaged) you can simply replace the glass.

If you need a frame to be made, measure the rough opening you have. The frame will be made to fit that space.

The two types of glass we have standardized on is 6mm (1/4” thick) & 10mm (3/8” thick) The difference between the two types of glass is the STC rating associated with each thickness.

The ¼”/6mm is rated around 31 STC and the 3/8”-10mm is rated around 34 STC.

For smaller windows, a 6mm will suffice. Larger windows or projects with louder equipment can use a 10m or dual glaze

One pane is referred to as a single glaze, two panes of glass with an air gap is referred to a dual glaze. A dual glaze should be used for larger size openings and/or if equipment is expected to be constantly on or loud. We have standardized on using two glass thicknesses in dual glaze frames – a 6mm & a 10mm - to stop noise on different frequencies and achieve a higher STC rating (dual glaze 6mm & 10mm have 40+STC).

If a dual glaze is required; it is recommended to purchase a fully fabricated frame to ensure the sealed air gap in the middle is as clean as possible prior to sealing. It can be difficult to achieve this when installing a dual glaze setup on site or without proper experience. A single pane setup would be recommended when installing yourself.

The concept behind tilting the glass slightly (industry has anywhere between 3-7 degrees per pane) is to avoid having either a trace light reflection going directly back into the lens. Although this issue is minimal when using the OptiClear Anti Reflective glass, there is still a minute amount reflection. A tilt is used for extra effort to have as much clarity as possible, although it can rarely be noticed with an untrained eye if you are unable to tilt at all.

Yes! You can most definitely order any thickness of glass in any size and handle the framing yourself. When visiting our site, simply click “Just the glass” and enter the dimensions and quantity needed for your project.

The glass can be installed using simple glazing techniques. You can use 1/2" wooden stops (available at your local hardware store / wood shop) and acoustic glazing tape or rubber channel.
