NXT e-Zone

Low-e Roof barrier for the underside of roof decks

NXT e-Zone is an interior heat barrier coating, formulated to be sprayed onto the underside of the roof. This easy to apply coating creates an effective barrier that will stop up to 77% of the radiant energy heat transfer into the attic space.
The physics behind NXT e-Zone relies on the emissivity (“e”) value. This is the ability of a surface to emit or absorb radiant heat energy. The lower the “e” value, the more efficient it is in managing energy. NXT e-Zone has a low value of e-0.25, making it a highly efficient coating for the underside of a roof surface. This can translate into greater energy cost savings for the building.
This two-part system creates a cooler attic space during summer which decreases the amount of heat being absorbed by ceiling insulation. In turn, this lowers the temperature and improves the comfort of living and working spaces below.
NXT e-Zone also provides the benefit of working in reverse during winter, helping to retain warmth. Heat is prevented from escaping through the roof; thus retaining the warmth and further reducing your energy costs.
By combining NXT e-Zone with NXT Cool Zone, you can enter the Nutech Comfort Zone!

Application Guide

NXT e-Zone Roof Barrier may be applied by brush, roller or airless spray. The preferred method is spray.

Airless Spray: Recommended pressure is 2000 psi using tip size 0.019 to 0.021” (0.48 to 0.53 mm). For best results use a spray pump size 3/4 GPM or greater.
Roller: Use a 3/8” (9.5 mm) synthetic-nap roller cover. Use a nylon/polyester device.

Because of its use as an attic barrier, with roofing nails penetrating the surface, brushing or rolling may be difficult application methods.


Apply to a clean, dust-free, dry surface. No need to prime.

Remove all surface contaminants with an appropriate cleaner.


Use a spatula to put entire contents of Part B into the 20L Part A pail.

Mix thoroughly for 5 minutes with an electric mixer before use. Hand mixing is not sufficient.

Only mix as much material as can be applied in one day.

Clean Up

Use warm, soapy water. Follow sprayer manufacturer recommendations when cleaning equipment.
