Frequently Asked Questions
Lexar has a 4’x24′ fan folded piece, which means you’ll cover 3x the area as you would with a smaller 4’x8′ piece.
You only have to tape it every 24 feet, as compared to every 8 ft with a 4’x8′ (3x less taping), which saves physical wear and tear on the installer (you).
It arrives to you as a 4x’4′ cube, so less awkward to handle than the 4’x8’.
It is treated, so termites, ants, and other critters will stay away from your insulation – (non treated boards serve as a haven for bugs, ruining their r value).
It has a 6 inch gridline, which helps guide you as you measure to place rebar and/or radiant tube heating.
Lexar’s attached 6 mil vapor barrier makes it so you don’t have to source and install a separate one, saving you time and stress compared to other insulations, where you have to source one separately
What is EPS foam, and will it save me money on my heating/cooling costs?
Based off our founder’s testing on his own buildings, and independent case studies, EPS foam, or “expanded polystyrene” will have a 50% higher r value long term compared to the other type of foam known as XPS, or “extruded polystyrene.”
The independent case study, started in 1993 and completed in 2008, put EPS (Lexar) and XPS under the same building in Minnesota. After 15 years, they tested the r value of each.
The XPS had degraded to an r value of 2.6, while the EPS was 3.95.
What that means to you is you’d pay significantly more to heat and cool your building if you go with XPS.
Maybe, but what do your competitors say about you?
We are confident enough in the science behind our product that we do not mind if you look at what our competitors use as a “put down” sheet.
You’ll note that it is all about water getting into our foam. The only thing it talks about is water.
Luckily for you and us, Lexar foam boards have an attached vapor barrier, so water will not be getting into our product when its under your building.
