Our fully sound tested IsoDoor V is recommended for more basic wall assemblies or communicating door assemblies (combined with our other door models in the same opening). The IsoDoor V is well suited for any wall with an STC rating of 42 or lower. The standard size for our IsoDoor V is 36” wide and 80” tall. With a slab thickness of only 1-3/4” and a standard backset of 2-3/4”, the IsoDoor V fits any standard door handle. Each IsoDoor V arrives pre-hung with a jamb to match your wall depth, up to 12" included in the price. All perimeter seals are included with a fully mortised automatic noise reduction door bottom, acoustic threshold, and rubber perimeter seal system.

The IsoDoor V is manufactured by IsoStore. We offer a full year warranty on workmanship and materials from the date the noise reduction door is received.

JAMB DEPTH

Measure or calculate the depth of the wall from the two outside finish layers (include all layers of drywall and isolation products). Our standard door price allows for extra wide jambs up to 12". Custom jambs are available for depths greater than 12".

If communicating doors are planned, measure the overall depth of the cavity where the doors will be installed, divide by two, and subtract 1/4" from each jamb depth. This 1/2" gap is used to relieve air pressure into the wall cavity when closing both doors.

DOOR WIDTH

Our standard door price is based on a 36" door width for a 38" rough opening. An option to change the width to 32", or 30" is available. Other custom widths are available upon request.

DOOR HEIGHT

Our standard door price is based on an 80" door height for an 82" rough opening. An option to change the height to 84" or 96" is available. If another custom height is required, please look at our IsoDoor SD, IsoDoor HD, or IsoDoor HD LF models.

PANEL DESIGNS AND GLASS KITS

The IsoDoor V is currently only available in a flush panel ready for paint or stain.

IsoDoor Door Swings

Installation of our doors require at least two people. The steps involved with installing a sound door are very similar to installing a standard door. Careful attention must be paid to the rubber perimeter seals and adjustment of the automatic door bottom to achieve the full STC ratings achieved in our lab testing. Each IsoDoor V will ship with a full installation guide and receiving instructions.

The IsoDoor V was sound tested most recently in 2018 as an inoperable individual door at Intertek. The results of this test is available upon request.

COMPARING PERFORMANCE

Unfortunately, the accuracy and consistency of STC tests varies greatly depending on the lab and the year testing was completed. The majority of testing we have found is no more recent than the mid-1990′s with some testing back to the 1960's. To make it worse, many of the tests were done in the manufacturer's own facilities in labs that cannot accurately measure the ranges tested.

Because of this, a competitor’s STC 52, unless tested recently, is not necessarily better than an STC 46 from us. Or a competitor’s STC 46 , unless tested recently, is very likely much worse than an STC 46 from us. The STC calculations are constantly changing and becoming more stringent, and new acoustics labs are more accurate than ever. We tested our line of IsoDoor in 2012 in an acoustic lab known as the most accurate lab in the United States. Our ratings may appear lower than some of the highest ratings you will find, but we are confident that our STC numbers will meet or exceed the competition and can be duplicated both in the lab and in the field.

COMMUNICATING DOORS

We suggest creating a communicating door assembly to increase isolation significantly beyond the IsoDoor HD. Our tests show STC/OITC ratings with the IsoDoor HD as high as 65/50 which meets or exceeds double stud walls. Combining the IsoDoor V with the IsoDoor HD or combining the IsoDoor HD with the IsoDoor HD LF will help avoid common resonance issues that occur when two similar materials are installed in the same assembly.
