Roof Ice Melt System: RIM2


RIM2 system is our energy efficient offering for areas with less severe wind speed, elevation, temperatures and moderate snow load areas with roof snow accumulation 6” –15” (15 – 38 cm) and annual snowfall 20” – 100” (51 – 254 cm).

RIM2 system consists of RIM2 panels that use lower wattage self-regulating cable providing energy efficient solution for moderate snow load areas. RIM2-Eave panels embed 2 runs of self-regulating heating cable providing sufficient power output required for moderate snow load areas. RIM2 system includes panels specifically designed for eaves, valleys, channels, rakes and flat roof sections.

RIM2 Eave Panel (RIM2-E):

RIM2-E panels are designed to mount on the roof eave and minimize the formation of icicles and ice dams during the winter season. RIM2-E panels embed 2 runs of energy efficient self-regulating heating cable in a specially designed base that directs most of the heat to the top surface for maximum efficiency. The base and heating cable are covered with cover panel which transfers heat along the continuous edge of the roof. The cover panels are available in variety of colors to match the roof material.

RIM2 Valley Panel (RIM2-V):

RIM2 Valley panels are designed to mount in the roof valleys and provide a heated melt path down the valley and eliminate water ponding in the valley area.  It embeds 2 runs of energy efficient self-regulating heating cable which is mechanically protected by a cover panel.

RIM2 Low Pitch Eave Panel (RIM2-LPE):

RIM2 Low-Pitch Eave panels are specifically designed for integration with metal roof systems and for applications involving roof pitches of 3:12 or less.

RIM2 Snow Melt Panel (RIM2-S):

RIM2-S panels are typically used to melt snow on a flat or standing seam roofs. RIM2-S panels embed 2 runs of energy efficient self-regulating heating cables in a specially designed base. The base and embedded heating cables are covered by a cover panel that transfers heat to a wider section of the roof. One of the applications for RIM2-S panels is to install them in between standing seams to melt the snow from the entire sections of standing seam roof. RIM2-S panels have also been used on flat membrane roofs to provide melt paths for the snow towards drains.

We also offer specialized RIM panels for Rakes, concealed Snow Melt, Channels and other custom roof features.
