What is the proper way to install Ultralight Insulation Boards?

The perfect installation for Warmup Ultralight Insulation Boards would be a tight and staggered seams. Instead of lining up the edges of the boards perfectly, it is extremely important to offset them a bit to provide a thermal break. A thermal break is a barrier that stops heat from moving easily between inside and outside. When you have a good thermal break, your insulation works better, which means your home stays warmer without needing to turn up the heat all the time.

Can I install a towel warmer bar horizontally?

Warmup recommends towel warmers to be installed horizontal only. Towel warmer bars are designed to evenly distribute heat across the entire surface of the towel. Towel bars work most efficiently when towels are hung flat against them. Hanging a towel vertically reduces the surface area of the towel that’s in contact with the bar, which means it will take longer for the towel to warm up, and you might not get the desired warmth. When you hang a towel vertically, only a small portion of the towel comes into contact with the bar, resulting in uneven heating. In addition, towel bars are designed and tested to be installed horizontally, according to our installation manual. Installing them vertically could potentially compromise their structural integrity and safety.

What is a TDR Meter and how do I use it?

The TDR Meter is used to measure the distance to an existing fault in the wiring of your heating system. It sends an electrical pulse into the connected cable, traveling along the cable until it reaches the fault and then that pulse is sent back to the TDR. The time it took for that pulse to reach the fault and travel back is measured and converted to a distance reading that will appear on the TDR Meter.
