21K BTU VSD Smart 115V Marine Air Conditioner Unit Brushless Variable Speed Soft Start Reverse-Cycle Heat

Self-contained VSD air conditioners provide the best existing technology: compressor with brushless DC motor and inverter that constantly controls speed and delivers cooling power (Variable Speed Drive); reverse blade brushless fan; electronic expansion valve. Constant Flow technology fan (i10 and i16 only) Twin Rotary compressors 21.000 BTU/h max output.

The compressor continuously changes its running speed depending on the ambient and set temperatures. It operates at maximum power to cool the cabins rapidly, but once it reaches the set temperature, it reduces the power and electric consumption. In this way, it maintains the optimal comfort level with the minimum consumption. The inverter works between 20 and 100 Hz.

great for what im doing. maybe not as good in a vehicle though
Size: 36 sqft
decent product. not as thick as typical sound deadening but definitely cheaper. and for my application, i didnt need a name brand thicker material. i am putting it on our heat and ac vent and intake pipes during our remodel. sound travels from room to room in our old house through these vents and pipes so a little sound deadening goes a long way

Buy the individual cross cut sheets, not these rolls.
Size: 36 sqft
I ordered two different types, individually cross cut foil rectangular pieces and these rolls both containing 36. sq. ft. The cross cut sheet blows this away. This stuff is much thinner, much less butyl rubber, much flimsier foil, and needs twice as much to have the same effect. Once you put it on, you cant remove it. The other brand's 2mm is much thicker than this.

Cheap Insurance Against Headliner Failure
Size: 4-pack
Cheap Insurance Against Headliner Failure If you’ve ever owned a Jeep with a hardtop, you already know that heat, cold, humidity, and constant temperature swings can be tough on adhesives over time. Even when replacement headliner kits include their own adhesive, I still like having a high-quality automotive adhesive on hand for extra peace of mind. This 3M product has been one of my go-to choices for headliner work because it is specifically designed for automotive environments where materials are exposed to extreme summer heat and winter cold. The last thing anyone wants is to spend time installing a headliner only to have corners start sagging or sections pull away months later. The spray pattern is consistent, the adhesion is strong, and it provides the confidence that the installation will hold up long-term. I have found it especially useful for Jeep hardtops, where temperature fluctuations can be much more extreme than in a traditional vehicle. The cans arrived well packaged, and having multiple cans on hand is convenient for larger projects or future repairs. For Jeep owners, restorations, headliner repairs, upholstery projects, or anyone wanting a little extra insurance against adhesive failure, this is a product I would not hesitate to keep in the garage. #FoundItOnAmazon #JeepLife #JeepJKU #HeadlinerRepair #3M #AutomotiveProjects #GarageEssentials #DIYGarage #AmazonFinds #JeepMods #AutomotiveMaintenance
