A Dutch company called PXA Nederland sent me these samples of Isobooster insulation which might be the most fun and innovative product I’ve received. It consists of 3 repeating layers. The first is low density polyethylene or LDPE bubble wrap with small air cushions. The second has large air cushions and the third is a polyester or PET film treated with evaporated aluminum.

Let’s look at the three modes of heat transfer.
Conduction is the flow of heat through solids. Materials with high density conduct heat faster than materials with low density because air is a poor conductor.
Convection is the flow of heat through a gas or liquid. Heat warms air molecules which expand, become less dense and rise.
Radiation is the transfer of heat through infrared rays which is a band on the electromagnetic spectrum between visible light and microwaves.

Isobooster insulation addresses radiation with multiple layers of aluminum foil, and addresses conduction with multiple layers of bubble wrap.

The reflected infrared radiation vibrates water molecules and evaporates them. This makes the air in the wall cavity and in interior spaces drier and it decreases the relative humidity. This constant layer of hot, dry, rising air always moves along the surface of the reflective foil - a phenomenon called the Coanda effect. Dry air insulates twice as well as humid air, leading to a healthier environment, and preventing mold.

ADVANTAGES
Installation is very simple. It can be cut to size with scissors or a box cutter. It’s attached to wood studs with staples or capped nails. All the seams must be taped up. It doesn’t release any harmful fibers or dust, it doesn’t cause any skin or airway irritation and it doesn’t give off any toxic fumes. Since it’s flexible, It can be easily wrapped around pipes and outlets in stud bays. It’s great for both renovations and new projects.

It is 8 times lighter than conventional insulation materials, so transportation and labor costs are cheaper. It is maintenance free and DIY friendly. It’s especially useful on houseboats where every kilo or pound counts. It can also be used on the remodel of old homes and buildings with space constraints. It’s very versatile. It can be on walls, floors, basements, ceilings and roofs, both inside and outside.

It is environmentally friendly. The manufacturing of LDPE and PET film is clean and efficient, it has low CO2 emissions, and it doesn’t create much waste or harmful substances. It is also not an energy intensive process like traditional insulation. Isobooster not only reduces the energy consumption of a building, it is also 100% recyclable. It also has no thermal drift or loss of R value over time. It is also insect and rodent repellent.

DISADVANTAGES
Its R value is 2.4 per inch, comparable to fiberglass. However, if you’ve watched my R-value video, you know that the testing method favors fibrous insulation. If you look at the actual thermal resistance due to reflection of radiation, rather than conduction, it probably performs much better.

I was disappointed with the material’s fire resistance. It singed initially, but after prolonged exposure to the flame, it ignited. It costs 13.77 euros per m2 or 1.55 dollar per square foot. It’s even more expensive than rockwool which is $1 per sq ft. Most importantly, this is a vapor barrier with a very low perm rating. In older buildings that don’t have an HVAC system, you need to vent the cavity to allow water vapor to escape.
