Some welds need more than protection from the elements. They need controlled heat retention before, during and after the weld.

SUM Ltd’s Weld Heat Retention Blankets are designed to help maintain temperature around the weld area, supporting pre-heating, interpass temperature control and post-weld heat retention in demanding industrial environments.

Built with the same attention to material selection, fit and fabrication that goes into our custom removable insulation solutions, Weld Heat Retention Blankets provide a practical, reusable way to help manage heat loss at the worksite.

For field welding, maintenance, fabrication and other applications where temperature matters, it’s another purpose-built solution from SUM Ltd.
