Which is better for Camper Van Insulation: 3M Thinsulate or Havelock Wool? Ah, the great debate! Is 3M Thinsulate or Havelock Wool better for camper van insulation?  After working with, and installing, both of these materials over the course of our many DIY van builds, we are ready to compare them across various important points for you.  In this guide we will discuss: Basics of Camper Van Insulation What is Havelock Wool? What is 3M Thinsulate? Comparison Across: Thermal Performance Cost Installation Moisture Control Let’s get to it! Basics of Camper Van Insulation The proper camper van insulation strategy does two things:  Keeps your camper van interior cool in the hot months And, keeps your camper van interior warm in the cold months However, insulating a camper van is a bit less straight forward than a house due to the empty sheet metal pillars that can be hard to reach, and the fact that air is constantly moving below the chassis.  If you are interested in the more fine grain details of how to thoroughly insulate a camper van, the science of insulation, and more, head on over to our dedicated Camper Van Insulation Guide. This guide is dedicated specifically to comparing the two most common choices. What is Havelock Wool (Sheep Wool)? Havelock Wool is sheep wool, a fantastic thermal insulator known for hundreds of years.  It has extremely high thermal conductivity that does not degrade over time, even with the added job of moisture management as it absorbs and releases water.  In addition to its insulating qualities, sheep wool has sound dampening qualities, filters air, and does not allow for the growth of mold and mildew. Havelock Wool is the leading seller of sheep wool for camper van insulation.  You may also find other brands depending on where you live, and if you do, share them in the comments section! Shop Havelock Wool What is 3M Thinsulate? 3M Thinsulate was developed as acoustic insulation for vehicles as the demand for quieter “in cab” experiences has greatly increased over the years.  However, it turns out that this lightweight and acoustic dampening material is also a fantastic thermal insulator.  3M Thinsulate is a man-made blend of polyester and polypropylene that is extremely easy to work with, is flame resistant and, does not off gas. NOTE: Throughout this guide, we are specifically speaking about 3M Thinsulate SM600L when we reference “3M Thinsulate”. Shop 3M Thinsulate Are there other insulation alternatives? There are absolutely other insuation materials on the market; however, we urge you to think about the unique needs that camper vans require in terms of insulation: You want to avoid chemicals that may off gas as you are living very closely to your walls.   You need to be able to insulate tiny cracks, gaps, and pillars completely.  Not all materials can stuff into small spaces easily.  You want to be careful with spray foam (hire a professional!) as irreversible damage can be done to the body of your camper van if
