Product Overview
The wall radiation shield (also known as the wall thimble) is used when the chimney passes horizontally through a combustible wall. The EWRS telescopes to adjust for wall thickness from 6" – 12", so no painting is required. The inside finish trim is separate from the EWRS, allowing for easy installation before or after the wall finish is applied. The Insulated Wall Radiation Shield - aka Thimble (EWRSI) is designed for installations in energy efficient houses which have tightly sealed vapor barriers. The EWRSI is fully insulated and has a flange to permit an air tight seal to the vapor barrier. It can be installed into an existing home but since it must be installed under the drywall it is most often used for new construction. Flue extention and trim ring included.
The Stainless Trim (EST) for the EWRS is a decorative trim cover for the exterior wall plate of the Wall Radiation Shield (Wall Thimble) that prevents water infiltration while providing adequate heat ventilation. It covers the existing galvalume exterior plate of the EWRS for a more decorative look.
