    This is a Watts Radiant UnderFloor mat, a variation of HeatWeave heating mats that are used for already existing flooring. The 1200916U2HW mat is designed to fit in between already existing joists and can be stapled in place quickly and easily. Designed to heat wood, vinyl, laminate, and tile floor coverings with ease, the UnderFloor mats use the same industry leading wire as other Watts Radiant electric radiant heating products. The wires are shielded and fully grounded, guaranteeing operational safety in a vast range of existing building types.

    Product Features

    Dual High-Grade Copper Heating Elements
    The heating wire's heating element is made from high quality oxygen-free copper, giving the wire uncompromising heat transfer efficiency while retaining flexibility. The entire wire contains a pair of twisted heating elements which keeps the electromagnetic field generated by the wire to a minimum.

    ETFE Wire Insulation with Grounding Jacket
    The heating wire is enveloped in a durable ETFE insulation. This unique insulation offers significant resilience against chemical and temperature corrosion. The two wires are then bound together by a stainless steel jacket for grounding and durability purposes.

    Single Power Lead
    Both wires connect to the power supply with a single power lead, simplifying labor and reducing installation time.

    Flexible Mesh Siding
    The sides of the mat are made of a flexible material arranged in a grid. This arrangement allows the mat to be stapled to floor joists using simple wood staples.

Is closed cell insulating foam an option to spray on the heating mat?
Allan 
from Nevada 
May 25, 2016
Answer
Spray foam is an option, but there are a couple of important precautions that must be observed. The 2" air gap above the mat must be maintained under all conditions, and the total R-value of the foam cannot exceed R-19. Also, the foam cannot be in direct contact with the mat, so some sort of barrier will be needed to separate the two.

I have a old house, I'd like to apply a heat source between floor joists in the basement under current tile floors.What would you advise?
Bob S. 
from Rhode Island 
January 19, 2016
Answer
The UnderFloor mats in your inquiry are likely the simplest solution, but may consume a lot of energy depending on how large of an area you are heating and how frequently they will be used. They also will require that an electrician pull new circuits to power them.

If your home already has an existing boiler, it may be more cost effective to suspend radiant tubing in the joist bays.

Please feel free to call us and discuss these options further.
