Stupid question
We have infrared heaters suspended from the ceiling. Our stack of MDF is near one of them. The top sheet is always drying out and cupping, making it difficult if we have to cut full sub tops on the CNC for hi bars, overhangs, etc. If it goes on the panel saw to cut 2″ lathing, no biggie, I don’t care, but I would love to prevent this.
Two things I have considered, an insulation board with foil backer to reflect the heat, or a plastic tarp to keep the moisture from getting out. Anyone have a suggestion?
I really only think they would need to cover overnight, as the heaters rarely run once the shop is opened up in the morning unless the dock doors are open for an extended period of time.
Please don’t suggest moving the stack of MDF, smartypants, I like it where it is.
What about a real thin white piece of plastic a bit bigger than the sheets. This would reflect the heat and hold in moisture. The plastice tarp sound good too, but it may be kinda hard to deal with.
Can you move the heater?
We intalled some new duct work over one of our heaters. We built a shield over the heater
…an insulation board with foil backer to reflect the heatI’ve never tried it, but it sounds good. Don’t go with the tarp. Waste of money. The moisture is baking out of the sheets, not just leeching out. Tarp won’t help much, as it is leaving faster than it can be absorbed.
I imagine that heat must be susceptible to the law of squres (like light does). Something like: the reduction in wave strength is proportional to the square of the distance. Heat moves through air much slower than light, so friction must slow it down as well.
Keep them covered all the time. Reflected side up, moisture barrier down. Watch the end grain. You might clamp them if it will be an extended stay. Not for the tenth or fifteenth sheet, of course, but first one through five, anyway.
I can’t believe I wrote something that intelligent sounding when I don’t even know what I said.
