Product Use

View our Product FAQ for answers to common questions about our line of IsoDoors.

Our proprietary and fully sound tested IsoDoor SD will achieve an STC and OITC rating appropriate for most projects. The IsoDoor SD is well suited for any wall with an STC rating of 55 or lower. The standard size for our IsoDoor SD 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 S fits any standard door handle. The weight of the IsoDoor SD is 230 pounds, about 130 pounds more than a solid interior door core. Each sound deadening interior door arrives pre-hung with a jamb to match your wall depth, up to 10" included in the price (deeper jamb depths available on request). All perimeter seals are included with a fully mortised automatic door bottom, acoustic threshold, and rubber perimeter seal system.

Our line of IsoDoors are designed and manufactured from start to finish by IsoStore. We offer a full year warranty on workmanship and materials from the date the sound deadening 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 30", 32", 34", or 42" 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. Other custom heights are available upon request.

DOOR SWING

PANEL DESIGNS AND GLASS KITS

We now offer one-sided panel designs to match your aesthetic requirements without sacrificing performance. This option is available in both paint or stain grade. The side with the panel design is defaulted to the outside of the room (based on door swing selected) unless noted otherwise during ordering.

Installation

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 SD will ship with a full installation guide and receiving instructions.

We would recommend installing the IsoDoor SD or IsoDoor HD doors as interior doors only. If an exterior installation is required, use a quality oil based paint and paint with a quality exterior paint on all 6 sides.

DOOR SEAL DESIGN

Our door seals create dead air space and redundancies allowing for an easy installation with more room for error. Because of this, performance from our lab tests are easily replicable in the field. Other isolation door manufacturers have bulky seals that appear to install easily, but often create major deficiencies in the corners and will require adjustment over time.

Tests

The IsoDoor SD was sound tested most recently in 2012 as an operable individual door at the most accurate acoustics lab in the United States using the most recent ASTM standards. A summary of the results for the operable individual door tests can be found in the product specs download. We have also completed independent sound tests of communicating assemblies using our IsoDoor SD with our IsoDoor HD and IsoDoor V. The results of these tests are 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 H. 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 SD 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. Two IsoDoor SD can be used in the same communicating assembly with a slight change in core design to avoid these resonance issues.

*All test results shown in this table were achieved through third party testing from accredited laboratories. The full test is available upon request.
