How To Measure and Cut-To-Size Policy [X]


Cut-To-Size Items are Non-Returnable!

As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade. Please review our full return and shipping policy here.

Measure Twice, Cut Once

Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.

How to Use a Measuring Tape

Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.

Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.

Features of a Measuring Tape: Sliding End Hook

The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).

2021-06-11I called and got a rather cold reception from other end. Then I was told there is a 16 week wait time for materials or it can be subcontracted. I found another Greenhouse Supply company that didn't charge $300 delivery. In fact it was free. Ordered Thursday and being delivered Sunday. Yes Sunday.
2021-02-15Good customer service - agents willing to listen. After delivery delay, company representatives worked out a resolution that helped to remedy matters for me. Thank you.
2021-02-12BE AWARE THERE MAY BE SHIPPING ISSUES - First review was deleted, so I'll just quote from my email to the company rep - I am not sure of all of the details of your summary, but I have worked out a solution with ____(independent shipping company rep) here in __ to have the materials shipped to an alternative address where I will have crew to take the crate off the truck. I have returned every communication that was made to me, but it has taken me a few steps to do this additional coordination here in __. I may have missed the fine print of the disclaimer on our website, but I know I selected and paid additional cost for a residential delivery, and I do not know of many residences with loading docks. ____ and I worked out a solution last week, but we have been experiencing inclement weather here this week. We?ve had an ice storm and an emergency declaration due to it, and I haven?t been in a position to ensure that the crew I have hired would be available to receive
2020-06-02need to make to make 30" for greenhouse proble 5" sections w/ a40" --42" front panel to open with a hinge you got some ideas
2020-02-25I am trying to find good quality PATTERN PLASTIC for my job. I am a seamstress. I have been trying to find Pattern Plastic that I will be able to use over and over I have copied my pattern out. Any ideas?
2019-09-06Just wanted to give some props to Robert. I have been trying to find sheets of poly-carbonate and channel for several days. Upon calling interstate plastics Robert was very informative and eager to land the sale. He took accurate notations of the products I needed and in a very short amount of time had emailed me a complete bid with shipping and packaging included. He also let me know of a sale on a higher grade product and provided me with a nice little discount. In my book the service was first rate and feel Robert went above and beyond to help a guy out on a late Friday afternoon. Thanks, Dow G.
2019-02-21I am trying to replace one twin wall panel in my 15-year-old greenhouse. I need 48"long and over 27+ inches wide. The last panel I tried to purchase was 37 inches wide, which is fine because I can make the cuts. I could buy even wider panels to have extra. I thought it was 6mm, but that is too thick and most of the kits like it are 4mm. Do you carry this thickness in twinwall?
2017-09-06Quick service.
2017-08-29Question..... I'm wanting to build a solar kiln, for drying wood. I plan on basically building a greenhouse with black plastic over wood, and fans circulating air, and dehumidifier. It will be getting pretty warm, but probably not over 140-150 degrees........The question is, can this product handle that much heat?
2016-03-17Interstate Plastics has a very helpful staff, thank you to your entire team. They helped us work on a large greenhouse project for our farms and are very happy with the results.
2015-11-10What a headache it was to figure out all the sizes and caps and screws I needed for a fairly large greenhouse project. Thankfully Interstate Plastics did everything they could to make this as easy as possible. Much thanks to your crew!
2015-10-12Beautiful, well made product. Professional service too
2015-08-31Great product with lots of support from the team at interstate plastics. They have all the extra bits and pieces needed for roofing and glazing. Top notch service.
2015-03-17Great instructional PDF and reference video. Thanks for all your help in making our concept work!
2015-02-16sourcing 3,000,0000 pcs of 7" x 10" twin wall polycarbonate per year or something similar - must be flexible in all directions and very strong. Price/pc needs to be $.04/pc. Is this feasible?
2014-11-05Great material, great support. Had a little trouble tracking down end caps. It turned out they do indeed sell them but it was not on the website so be sure to call in.
2014-10-29I was given very helpful information throughout the painstaking process of new roofing for our deck. Interstate Plastics made it easy and simple! (At least from the ordering aspect!) Fast responses especially over the phone. I was never put on hold for more than 30 seconds!
2014-06-05Although some sizes are unavailable online, I appreciate the helpful service Interstate Plastics provided me and my wife over the phone about hurricane protection.
2014-05-13Superb superb. Great shipping time for being on the east coast. Quality material at a fair price.
2014-05-09Strong flutes, indestructible. Great material with helpful service to boot.
2014-04-15This looks very cool on our carport. Ordering and having it shipped were super simple!
2014-04-14Great product at a great price. It's very flexible yet strong, and it looks fabulous as an awning!
2014-02-27Long sheet sizes with excellent protective shipping. No damage over multiple orders. Overall a pleasant experience ordering.
2014-02-18Beautiful material and great service.
2013-11-01Customer service was very helpful in placing my order. The twinwall arrived in flawless condition. Very happy with our overall experience.
2013-10-15Word to the wise - twinwall is not for window replacement! I ordered the wrong stuff so what can I say, but the shipping cost and times were very reasonable.
2013-03-11We were pleased to find that this holds well for roofing on an outdoor playhouse. Our children have managed to stay dry and it wasn't very expensive.
2012-10-16We used a twinwall material several years ago, for a special purpose. We were not able to find this recently, but found it on this website, with pictures, so ordered it. What we received was not what was pictured: the product sent had 3 walls. Other companies listed this product as multiwall. The salesman said this was not refundable, as it was custom cut. Misleading on-line catalog.
2012-10-08Got my material, thanks for the quick service.
2012-10-02I ordered this for my greenhouse project and it has worked perfectly! Insulates well and easy to install. Material arrived within a week and was in great condition. Once I got it I needed to cut it and was able to call for advice on the best way to cut it which was extremely helpful.
