Green Glue Tubes and Buckets

Scroll down a little bit to see our new Green Glue calculator.  It will help you calculate the total amount of Green Glue you need down to the very tube in each of the application levels.  The calculator also calculates Green Glue in buckets when using our dispensing gun.  If you apply Green Glue with a trowel then you will cover roughly 10% less per bucket compared to using our dispensing gun.

Tube Coverage
Supreme: 11 square feet per tube 132 square feet per case
Normal: 16 square feet per tube 194 square feet per case
Good: 32 square feet per tube 384 square feet per case

Remember when calculating total square footage, one of the bigger advantages Green Glue has over pre-damped drywall is the fact there there is no waste

 

5 Gallon Bucket Coverage With Dispensing Gun
Supreme: 245 square feet per bucket
Normal: 365 square feet per bucket
Good: 730 square feet per bucket

 

2 Gallon Bucket Coverage With Dispensing Gun
Supreme: 98 square feet per bucket
Normal: 146 square feet per bucket
Good: 292 square feet per bucket

 

Buckets are the affordable alternative to Green Glue tubes. But often project square footage does not divide evenly into full buckets. You can help combat this by supplementing buckets with a few tubes or the 2 gallon Green Glue bucket to reach the correct amount of square footage for your project so you don't have to over-buy.

Supreme, 3 tubes per 4' x 8' sheet, will provide no audible improvement in STC ranges, but a 35% to 45% increase in low frequencies. Supreme coverage is useful in home theaters, recording studios, and band practice areas. 

Normal, 2 tubes per 4' x 8' sheet, is the recommended coverage amount for most sound isolation projects.  Normal coverage yields great results in both STC ratings (high frequency)  and OITC ratings (low frequency).

Good, 1 tube per 4' x 8' sheet, is a cost effective solution for sound isolation issues.  The performance of this coverage amount is about 35% to 40% less than the Normal amount, but still outperforms products like sound board, homasote, resilient channel, and MLV.  Definitely worth considering if you are on a budget, but still want high performance.

SilenSeal Cases and Tubes

SilenSeal tubes are 28 ounce tubes so they fit in quart sized caulking guns.  These are not the same size caulking tubes you see at Home Depot type stores.  They are over twice the size.

With a 1/4" bead you can caulk 85 linear feet per tube.

With a 3/8" bead you can caulk 40 linear feet per tube.

If you were to use SilenSeal on a wall or ceiling where the sheetrock is hung well, this will work out to around 1 tube per 100 square feet of wall space or ceiling space.  If you are using SilenSeal on both layers of sheetrock--be sure to include both layers in total square footage.

It is difficult to measure the amount of SilenSeal you will need for your project, but these numbers have been typically successful in our own installations.  If you need any help estimating SilenSeal then e-mail us.  It is common to purchase 1 case of SilenSeal with 5 cases of Green Glue.

Resilient Sound Clips

Estimating how many resilient sound clips you need is the same for WhisperClips, IsoMax clips, RSIC-1 clips, or RSIC-V clips. 

You will want to space the sound clips 48" apart for maximum resiliency, but you will need to decide whether you should space your hat channel rows 16" apart or 24" apart.

16" on center: Space your hat channel 16" on center if you are using 3 layers of drywall.

24" on center: (The recommended spacing of hat channel) Space your hat channel 24" on center if you are using 1 or 2 layers of drywall.  We recommend two layers of drywall for improved results in low frequencies.  Also, all sound tests you will see for any resilient sound clip is done with 24" spacing of hat channel. 

There are two options for laying out your resilient sound clips.  The standard layout uses the least amount of clips and is the most common way to layout resilient sound clips.  It is believed that the staggered layout increases the effectiveness of the clips being used.  You will notice, however, that the staggered layout uses more clips than the standard layout.  The staggered layout will require you to include roughly an additional 1 clip per 6 clips to your estimating total.  We suggest using the standard layout since the effectiveness of staggering the clips has not actually been proven and only costs more money/takes more time to layout pattern of clips.
