PVC - Smooth Both Sides - Color White on both sides
TPO - Smooth & Frosted Side - Color White on both sides
EPDM - Smooth & Textured Side (texture varies) - Color White on both sides
Membrane Ships Folded Depending on size of kit you will get one or two boxes (glue / membrane)
Membrane Length / Width It is recommended to get a size that is longer / wider than your unit due to possible curve of the roof, raised or lowered areas, removing the excess is much better than not having enough.
Membrane must be installed onto clean wooden surface, do not install on top of existing membrane, glue, etc.
1. Router all vent and accessory openings. Sand all openings, seams, and edges to a smooth finish. Remove all debris off roof with air hose.
2. Apply seam tape (2” minimum width) evenly onto roof and sidewall to cover any sharp edges, it is required that seam tape be used to avoid edge splits. (We do not provide seam tape due to different sized needed)
3. Make sure all screw heads and surfaces are smooth and level throughout, raised screws will snap and puncture membrane and is not covered under warranty.
As soon as possible, while on top of clean unit remove membrane from box, do not drag over edge of unit.
1. Do Not allow membrane to touch ground or dirty surfaces.
2. Do Not allow membrane to touch sharp objects or surfaces, including lifted screw head and edges. 3. Do Not drag the membrane as this can cause punctures and tears which is not covered under warranty.
4. Membrane can be glued either side down. Single-Ply membranes are the same color throughout.
Membrane Installation
1. Cut the membrane to fit roof length with an excess of at least 6” front and rear.
2. “Bed Sheet” the membrane. That is, fold it in half so half of the roof is exposed.
3. Apply adhesive in a wet film thickness of 8-10 mils with a short-napped paint roller to the exposed half of the roof. (1 gal. will cover approximately 160-200 sq ft.) brush can be used but is more difficult. 4. Lay the roof membrane over the wet adhesive, the membrane needs to be adjusted both in width (side to side) and length (front to rear) to ensure the membrane is as flat as possible before the squeegee process. Let surplus material drape over the side of the unit for perimeter finishing.
5. Remove all air pockets and wrinkles with a squeegee (gray neoprene head will not streak), linoleum roller; press firmly working from the center outward toward the edges, do not be on the roof during this time.
6. All wrinkles must be removed at this point for a quality installation. The roof will tighten and conform as the adhesive cures.
7. Repeat steps 2 – 7 for remaining half of roof.
8. Apply putty /butyl tape to the backside of the roof-edge molding. Then while holding the bar, draw surplus material tight with a downward pull, but do not stretch the membrane. Drive screws through molding, membrane, and roof framing members. For best application install molding from center of unit to ends. Alternative method, staple membrane in place using ½” staples 3”-5” apart then apply bar. 9. If roof-edge moldings are not installed on roof during this time membrane will peel-up as drying.
10. Apply putty /butyl tape to the backside of the front and rear termination moldings/caps. Front cap will lay on top of the membrane, membrane should lay on top of the rear cap. Reinstall termination molding using screw type fastener, make sure to screw into sufficient roof structure to prevent lifting. Both edges of the front and rear roof molding must be sealed with caulk/sealant. A minimum 3/8” bead will work for most applications.
Openings & Vents and Appliance Installation
1. Using a utility knife “x” cut all roof openings. Make sure you round all 90-degree corners to eliminate the possibility of running cuts.
2. Surplus material must be secured by staples or screws inside the openings, trim all excess material.
3. Apply putty/butyl tape to all vents and accessories, when installing if any bubbles are noticed in membrane smooth bubble to vent opening and secure vent with screws.
4. Seal around all vents and accessories. Apply sealant to all visible screw heads. There is no need to spread the sealant as you are applying it. A minimum 3/8” bead will work for most applications.
*Butyl tape provides the “Primary Seal” against water infiltration or penetration in these membrane roof assemblies. The lap sealant is a secondary seal. Butyl tape must be compressed 30% to 40% to perform correctly.
Either side can be installed facing down. Some people think for better traction to install with the textured size facing up and the smooth side down toward the roof (facing glue), some people think for easier cleaning to install the smooth side facing up.
My roof turned pink!
This will happen when your roof is exposed to too much carbon dioxide, you leave the unit indoors or covered too long with no access to fresh air, once the unit is outside the pink will slowly disappear.
Why is the roof wrinkled around all the vents and skylights?
The solvents in the 1021 self-leveling sealant temporarily swell the roofing membrane. In the warmer months it takes 3-5 days to go away & 5-9 in the colder months.
Cleaning The Roof
Be sure to only clean each material with appropriate cleaning materials, we do not sell cleaning products.
Class A Customs no longer carries Alpha SUPERFLEX at this time.
Uniseal® is the world's best seal, and installing it is a simple process. After cutting a hole in the wall of a tank or other surfaces, the seal is inserted. Then the pipe is coated with a slippery detergent and pushed into the seal. The Du Pont Alcryn® is the key to the liquid-tight seal. When the pipe is pushed through the rubber-like Uniseal® from the outside, the inside Alcryn® wall becomes thin enough to allow the pipe to squeeze through and then forms a liquid-tight seal. The coefficient of friction with the plastic pipe is roughly three times higher than any other material, which allows it to create a better seal than with any other material.
Alcryn® melt-processable rubber
Long-lasting
Resistant to acids, oils, greases, gasoline & sewage
Withstands pressure & suction
Withstands heat & cold
Easy installation
Reduced labor & material costs
In static conditions, the seal is good up to 65 psi
1. Be sure to have recommended hole saw for selected fitting, check chart before cutting. 2. Using hole saw cut hole in wall, ensure that the hole is cut clean. Irregular holes could cause poor seating and possible leaks. File or sand the edges so there are no rough or sharp edges be sure to remove any remaining debris. 3. Insert the Uniseal with the wide surface facing out. 4. Make certain the pipe to be inserted is cut clean and square, file or sand the edges so there are no rough or sharp edges to cut the Uniseal surface. 5. Use liquid soap or Teflon lube on the pipe to be inserted. Insert the pipe into the Uniseal as far as needed to clear the inside of the seal by about 2".
6. Be sure to clean tank thoroughly prior to using removing any debris and lubricant residue.
Available in Plumbing Section or as Add-on with tanks
Before you build or modify unit verify rules and regulations. Codes vary by local health departments, not state. We are not aware of the codes or rules. We are not aware of what tanks or items you need.
Forward the documents and tank information provided to your local health department before purchasing to be sure these tanks will pass your local inspection, this is your responsibility.
Print the Water Tank List (Ctrl +P or Command- P will bring up the print window) NSF Paperwork (Ctrl +P or Command- P will bring up the print window)
NO NSF Logo
Class A Customs Fresh and Gray Water Tanks do not have the NSF logo molded into them due to changes NSF made regarding the use of the NSF logo. Class A Customs for several years was allowed to use the NSF Logo in our Fresh/Gray water tanks because the materials all the tanks are made from including the fittings are NSF Certified Materials.
The NSF Company does not allow for end users to use the NSF logo unless each item has been inspected and a certification paid for, the material that all of our tanks are made from are still the same NSF Certified Material that was used when we were using the NSF Logo in our water tanks, adding this extra step of certification is an unnecessary step but generates revenues.
The NSF Company does not allow vendors/manufacturers to link to the NSF paperwork unless verified NSF products are being used, Class A Customs has been verified and is allowed to link to the NSF Certified Materials page located on the NSF website. If needed your inspector can check on this regarding our company and website as we have already provided this information to the NSF company and have been advised on how to correctly use/link to the certification information on our website. Health inspectors would need to contact NSF directly to verify this.
My health department doesn't care, they won't look... my builders said it is ok... I am just updating tanks. We hear this and then get the call needing a different tank sent overnight to meet a deadline. It takes very little time to check before and saves you time and money. Forward the documents and tank information provided to your local health department before purchasing to be sure these tanks will pass your local inspection, this is your responsibility.
What does my inspector need when I go to inspections on the tanks? Print the Water Tank List (Ctrl +P or Command- P will bring up the print window) NSF Paperwork (Ctrl +P or Command- P will bring up the print window) Receipt of Purchase All tanks have the part number molded into the tank, inspector can verify tank.
What to ask on Fresh and Gray Water Tanks Size (Gallons / Measurements / Fresh to Gray ratio) Fittings (Size / Placement / Materials) Filling Procedure (Lockable Fill Dish / Materials) Tank Placement (Inside / Outside of unit) Clean Out Requirements
Water Tank Percent Calculation Examples 15% Large Gray Tank Than Fresh: Multiply (fresh tank size) x 1.15 = Tank needed
25% Large Gray Tank Than Fresh: Multiply (fresh tank size) x 1.25 = Tank needed
50% Large Gray Tank Than Fresh: Multiply (fresh tank size) x 1.50 = Tank needed
I have only so much room how many gallons can I get in that space? We do not recommend sizes or verbally give measurements, this is to avoid errors. Please look at the Water Tank List located at the top of each webpage or under Navigation Menu on mobile devices to see all tanks Class A Customs currently manufactures. You would need to compare the measurements of the tank with your available space and determine the best tank for your needs and application.
What fittings will I need for my plumbing? Do you have a"plug and play" or "concession kit"? There is no one size fits all application for the water tank set-up, it varies by application, unfortunately we are not aware of what items you will be needing.
I want the tanks in the video. The UM-2000 and UM-2500 were used in this video along with our Basic Plumbing Kit for the fresh tank, verify the measurements of the tanks will work for your applications.
