Prowool Insulation Van Gapfiller™ Kit
The Ultimate All in One Van an Camper Insulation Setup
  • Pack Size: 2.5kg Bag (Extra shredded for micro cavities)
  • Best For: Self build campervans, professional van conversions, touring caravans, and overlanding trailers.
Transform your vehicle into a comfortable, climate controlled, year round living space with our 100% traditional natural sheep’s wool. This kit keeps your living quarters warm during freezing winter nights and comfortably cool under the blazing summer sun.
Most importantly, it naturally manages the severe moisture and condensation that is unavoidable in mobile living environments. While rigid boards leave voids and synthetic materials trap moisture against metal, this loose, flexible wool expands effortlessly behind panels, around wheel arches, and inside tight structural ribs where nothing else fits.
Breathe easy at night knowing your insulation is 100% natural, chemical-free British sheep's wool.
Comprehensive Kit Breakdown (What’s in the Box)
We have eliminated the guesswork and the trip to the hardware store. Every single component is hand-selected to deliver a professional-grade installation with zero trade experience:
  • 2.5kg Loose Sheep’s Wool: 100% natural, completely chemical free, and specifically shredded. This mechanical opening process dramatically increases the wool's loft, allowing it to expand into irregular spaces without clumping.
  • Pre Cut Insulation Netting: Supplied pre cut to vehicle friendly lengths. This heavy duty mesh acts as a flexible retaining wall, keeping your wool at a perfectly uniform, slump free density over thousands of miles of road vibration.
  • Heavy Duty Application Tape: High tack, automotive grade adhesive tape engineered to bond aggressively directly to raw, painted, or primed internal van metalwork. It forms an unyielding grip to anchor your netting securely in place.
  • Handy Application Tool: A custom engineered, ergonomic tool designed to safely slide, pack, and guide the loose fleece deep into the van's hollow metal pillars, narrow ribs, and blind cavities without tearing the wool or scratching the paintwork.
  • Step-by-Step "How To" Guide: A crystal clear, jargon free visual instruction manual written specifically for DIYers. It walks you through prepping your metal panels, tensioning the netting, and hitting the perfect insulation density from start to finish.
Deep Dive: Why Prowool Van Gapfiller™ is Superior to Synthetic Insulation
1. The Ultimate Weapon Against Van Condensation
In a metal vehicle, your breath, cooking, and wet gear create high levels of airborne moisture. When this warm air hits the freezing cold outer metal panels, it liquefies into condensation, causing hidden rust, damp, and toxic black mold. 
  • The Synthetic Failure: Standard fiberglass, rockwool, or plastic insulation cannot hold water. Moisture passes straight through them or pools around them, trapping water against your vehicle’s metal skin. 
  • The Sheep's Wool Lung: Sheep’s wool is highly hygroscopic. It acts like a natural climate control system, dynamically absorbing up to 33% of its own weight in moisture vapor without losing its thermal efficiency or feeling damp to the touch. It safely draws dampness away from the metal panels and holds it until conditions change, safely venting it away when you crack open a window or roof vent. 
2. Complete Elimination of Thermal Bridging & Cold Spots
Rigid foam boards cannot bend and even Fibrous insulation rolls have their limitations. Trying to fit them into the curved walls, deep structural pillars, and complex window recesses of a modern van leaves hundreds of micro gaps. These gaps become "thermal bridges" uninsulated zones where freezing external temperatures bleed directly into your living space, creating instant draft lines and localized condensation. 
  • Prowool Insulation's Seamless Blanket: Because it is loose fill, our extra shredded wool effortlessly flows into and expands inside every hidden void, irregular corner, and structural box section. It packs tightly around complex wiring looms and plumbing pipes without squashing them, delivering a truly seamless, 100% continuous thermal barrier.
3. High Specific Heat Capacity (Cool Summers, Warm Winters)
Many people associate wool only with winter warmth, but its molecular structure makes it an incredible summer heat shield. Sheep’s wool has a remarkably high specific heat capacity. When the hot summer sun beats down on your van’s metal roof, the wool absorbs that thermal energy incredibly slowly, preventing the interior from turning into an oven during the day. At night, it releases that stored warmth slowly as the outside air cools down.
4. Total Safety in Confined Living Spaces
When you are sleeping in a tiny, enclosed campervan, air quality is paramount. Modern synthetic insulations off-gas volatile organic compounds (VOCs) and drop microscopic glass or plastic fibers into the air whenever the vehicle shakes on the road. 
  • Prowool contains zero harsh chemicals, zero synthetic fire retardants, and zero irritating fibers. It is completely non-toxic, entirely safe to handle without gloves or respirators, and guarantees clean, pure air inside your home-on-wheels. 
The Easiest DIY Project You’ll Ever Do
You need absolutely no prior building or trade experience to insulate your vehicle to a commercial standard.
By utilizing the traditional, globally trusted Net & Pack method, you simply tape your netting across the frame, pack the loose wool into the pocket to a uniform depth using the included tool, and seal it up. It is incredibly clean, satisfying, completely error-proof, and slashes installation times in half compared to measuring and scribing rigid boards.

  • Best For: Self-build campervans, professional van conversions, touring caravans, and overlanding trailers
