Symple Stuff Wall Sleeve

The window seal kit is compatible with all mobile air conditioning units, tumble dryers and dehumidifiers that utilise an exhaust hose and is suitable for use on casement windows with a maximum perimeter of 4m. The adjustable zip opening allows the kit to be used on any size of exhaust hose. The zip closes snuggly around the hose creating an air tight barrier. The window seal is designed to improve energy efficiency by keeping the cold air in your room whilst allowing the warm air to be expelled outside via the exhaust hose. It also offers protection from inclement weather and works as an insect barrier. The window seal kit is extremely easy to install using the 8m of supplied fastening tape and no tools are required. Use again and again and store away when not in use.
