Superinsulation
Videos
Superinsulation is an approach to building design, construction, and retrofitting that dramatically reduces heat loss by using much higher insulation levels and airtightness than average. Superinsulat
The passivhaus standard combines superinsulation with other techniques and technologies to achieve ultra-low energy use.

A vapor barrier is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through the wall, floor, ceiling, or roof assemblies of buildings and of p
Superinsulation
…is often to add layers of continuous rigid exterior insulation, and sometimes by building new exterior walls that allow more space for insulation. A vapor barrier can be installed outside the original framing but may not be needed. An improved continuous air barrier is almost always worth adding, as older homes…
6-mil (0.15 mm) polyethylene plastic sheet as vapour barrier between insulation and gypsum board
Glass wool pipe insulation covering a steel pipe as it penetrates a mock-up concrete slab whose opening will be firestopped. In this manner, the vapor barrier (in this case made of foil/scrim/kraft paper, called ASJ, all-service jacket, aluminium on the inside, white paper on the outside) can remain intact as it penetrates the fire barrier.
