The Problem
Traditional attic floor insulation only slows conductive heat transfer and doesn't prevent your attic from heating up. Up to 93% of summer attic heat comes from radiant energy that passes right through the roof assembly, making your home hotter and driving up cooling costs.
The Solution
Radiant barrier coatings (IRCCs) reflect up to 85% of radiant heat before it enters your attic. Apply directly to roof surfaces for immediate heat reduction without removing existing insulation. Professional-grade performance in a DIY-friendly water-based formula.

Frequently Asked Questions
Each gallon covers approximately 400 square feet with a single coat (2,000 sqft/5 gal pail). Only 1 coat required.
Mix well prior to application with squirrel mixer and then use continuous agitation while spraying to keep coating in suspension. Apply with a standard airless or HVLP type sprayer (low pressure), 5-15 tip. Clean roof surfaces of dust and cobwebs first and mask any electrical outlets, then apply one even, thin coat to all roof surfaces. Works well on wood, OSB, and metal substrates.
Yes. Radiant barrier coatings work alongside existing insulation and enhance their effectiveness. Apply to attic roof decking and rafters above your current insulation for maximum heat reflection. If you intend to put other solid insulation in the roof rafters (i.e., finished attic/cathedral ceiling), be sure there is a 2" air space between LO/MIT and the solid insulation below and only paint the surfaces exposed to that air space.
All products include a lifetime performance warranty when applied according to manufacturer specifications. LO/MIT should not need to be re-coated for the life of the roof.

If I could give 6 Stars I absolutely would. LO/MIT-II MAX Radiant Barrier Spray is a large part of my business. I've tried several brands of radiant barrier spray and will now only use LO/MIT-II. None better!

LO/MIT-II MAX Radiant Barrier Spray - 5 Gallon Attic Heat Reflective Paint (Covers 2,000 sqft)
I have used this product in numerous homes. The appeal to people seems to be the performance is quite good at a much less expensive price point than stapling foil product to the rafters. Finding labor to do that work is very difficult and as a result, not many companies offer radiant barrier installation service. The LO/MIT can be applied in a day, even hours, and at an extremely reasonable cost. Oddly enough the vast majority of hvac installers put their ductwork and systems in attics here in the Southeast, which is murderous in terms of conductive cooling losses from the duct work. This product cuts that way down. It also offers the homeowner an economical alternative, combined with air sealing and DOE rated levels of insulation, to spray foam. I would highly recommend it. Just be careful to include the coverage needed for the rafters because the entire attic roofline surface should be painted to get the most benefit.
