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).

ThermaGlas is a multi-wall polycarbonate sheet with special condensate control technology. ThermaGlas sheets have excellent thermal insulation that reduces the need for air conditioners to keep protected areas at the desired temperature and makes them more pleasant to work in. UV resistant, virtually unbreakable, and lightweight, they are easy to handle and install and are a perfect fit for applications in garden centers, holding areas, packing and holding areas, and more.

Using Palram's proprietary condensate control technology, ThermaGlas maximizes light transmission by minimizing the formation of condensation droplets that deflect light. With less condensation drip, moisture-related diseases become less prevalent. This improves the quality and yield of plants protected by ThermaGlas panels.
