Effective heat loss prevention The fireplace blocker blanket is made from thickened flameretardant Oxford cloth and is filled with sponge. It features a unique dividing line to keep the lining in place, ensuring reliable thermal insulation. This reusable blanket helps block heat loss overnight, keeping you warmer on winter nights. Yearround usage Designed to conserve heat in winter by keeping warmth inside, and to reduce heat transfer in summer by preventing cold air from escaping and blocking external heat. Use year round for a comfortable and consistent indoor environment. Convenient folding and storage The blanket is compact, lightweight, and foldable for easy storage when not in use. Its black color blends discreetly with most fireplaces, offering a lowprofile appearance. Maintain cleanliness After the fireplace has cooled, cover it with the fireplace cover to prevent debris and ashes from entering the living space. This helps minimize unwanted airflow and keeps floors and carpets clean, contributing to a tidy and fresh room. Use scenarios Winter nights: Place the blocker blanket around the fireplace opening to minimize heat loss and maintain warmth through the night. Summer evenings: Use the blanket to reduce heat ingress from outside, helping maintain a comfortable indoor temperature. Postuse cleanup and storage: Once the fireplace is cooled, apply the cover to prevent debris from spreading while keeping the room clean, then fold and store the blanket compactly until next use.
