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 Ultralight be used under heavy loads such as a car?


Although it would depend on the total point load (aka ground pressure), the answer is no. Warmup’s Ultralight was designed to be used in foot-traffic applications only.

Point loads greater than Warmup’s Ultralight Compressive Strength (10% Compression) of 32 psi (220 kPa) may cause a future failure. Warmup recommends a rigid foam that meets the specifications for heavy-point load applications.

Can Ultralight be used under concrete?


Ultralight is designed for and can be used under concrete up to 2″ in thickness. When concrete is greater than 2″ the benefits of the Ultralight diminish, therefore, in concrete larger than 2″ we recommend the use of other insulating boards suitable for the specific application.

Primers help encapsulate dust to improve bonding with the thinset you’d apply to lay the boards. But on brand new or clean subfloors this may not be necessary. When in doubt, consider a solvent-free floor primer like Ardex P51 or Mapei SM. If your subfloor is not level or has a lot of residues, such as glue remnants from an old vinyl floor recently removed, you may need to apply a thin coat of leveler to smoothen the subfloor in preparation for your project.
