              Aluminum profile with thermal isolation for energy-efficient windows I know choosing energy-efficient windows can be confusing. You want something that cuts heat loss but isn\u2019t just marketing. Thermal break windows are designed to reduce energy loss by inserting an insulating barrier into the metal frame, making them a strong upgrade for most homes.
