Warmup Insulation boards are an easy and efficient way of adding energy efficiency to your Warmup system and home. These boards, which are made of extruded polystyrene, act as a good insulator as they allow for reduced thermal conductivity. Essentially, they prevent heat from traveling down and allow for heat to reach your floor much faster. In layman’s terms, they act as a barrier between the subfloor and your heating element, allowing the heat to rise. Here are some other benefits of using Warmup Insulation Boards:
•When there is a concrete subfloor, the Warmup Insulation Boards can allow for your system to be up to 70% more energy efficient.
•With a concrete subfloor, the ramp-up time is 78% faster with the boards.
•What could have taken 2-3 hours to heat up can now heat up as quickly as 10-15 minutes due to the reduced thermal conductivity.
•They can pay for themselves in as quickly as 2 years.
•They are only ¼” thick.
•Easy to install. They cut with a utility knife.
•The boards are waterproof.
•The boards are mold proof.

1.2 Basic Installation
Prior to installation, you will need a few tools:
•A basic utility knife to cut the boards.
•Galvinized screws and tabless washers for non-concrete installations.
•Alkali fiber-mesh tape for installation in areas that do not see water often (kitchen, living room, etc).
•Polymer sealant and adhesive for areas prone to water (bathrooms and showers).
All surfaces should be thoroughly cleaned of all dirt and debris. When installing over an existing concrete base, it is important to remove all traces of existing finishes, contamination, etc. to allow for a clean surface. When installing over a new concrete base, make sure that it has been properly cured and dried to allow for shrinkage to occur before installation. Determine how you will be laying out your insulation boards in advance, based on your layout, cutting them to size with a utility knife. CLICK HERE for the installation video
1.3 Installing Over a Concrete Subfloor
When installing over cement, screws and washers are not necessary. You will first use a trowel to put down a modified mortar. Then you will stagger the boards and press them together.
In a dry area, use an alkali fiberglass mesh tape. Use a modified mortar over the top. Install your heating system accordingly.
When installing over a wooden subfloor, first use a trowel to lay a modified mortar. The boards will then need to be staggered and pressed together. The boards should be secured with a galvanized screw and tabless washer (making sure that the washer covers both boards but that the middle of the washer is not in the middle of the seam), one per foot. Tighten the screw washing until it is flush with the surface.
In a dry area, use an alkali fiber mesh tape between the joints. Use a modified mortar over the top. Install your heating system accordingly.
In a wet area, use a polymer-based sealant and adhesive between the boards and let dry (this usually takes between 20 and 30 minutes). Once dried, install the heating system accordingly.
