Vacuum insulated panel is one of 32 materials in this atlas, grouped under thermal: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.

Scores compare Vacuum insulated panel with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.

Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.

Deep introduction

Deep dive: Vacuum insulated panel

Vacuum insulated panel (fumed silica / fibreglass core + foil barrier) is a family of grades whose density 150–250 kg/m³ panels, heat band core inorganic; envelope polymer/foil, and fire letter system-dependent; core often A1-ish, skins not.

What “the material” actually is

Vacuum insulated panel is sold as grades, not as a single substance. Chemistry fumed silica / fibreglass core + foil barrier, density 150–250 kg/m³ panels, heat band core inorganic; envelope polymer/foil.

This atlas treats Vacuum insulated panel as a system: mill route, coatings, tests and the cavity it sits in.

Heat, fire and insulation

Conductivity note: centre-of-panel λ ~0.004–0.008 (declared bands). Insulation score 99/100 is relative to 32 entries — metals lose, VIPs and aerogels win.

Fire letter in editorial use: system-dependent; core often A1-ish, skins not. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.

How it is made and used

Origin: Dewar 1892 idea; building VIPs 1990s–, Scotland / Germany / Japan. The process chapter follows feedstock → conversion → forming → finish → install.

Uses span buildings to defence / safety. Pairings matter: aerogel.

Market and circularity

Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.

Circularity mark 40/100. Ask which scrap, which certificate, which year.

Seven chapters

Fire mark or insulation mark first?

Decision walkthrough on Vacuum insulated panel: fire 44, insulation 99, and one fact already on file — not a code stamp.

  1. Read the fire-performance mark — Fire on this hub is 44/100 — teaching comparison among atlas materials.
  2. Read the insulation mark — Insulation is 99/100 — heat-flow story, not the same question as flame.
  3. Sit one published fact beside them — Quick fact on file: λ: ~0.004–0.008.
  4. Sustainability is not a fire skip — A high sustainability mark does not replace fire protection in a real assembly.
  5. Not a building-code rating — Named tests, thickness and build-up still decide compliance — this page is literacy only.

On Vacuum insulated panel, fire 44 and insulation 99 answer different jobs; λ: ~0.004–0.008 grounds one real detail.

Editorial atlas marks. Not a code certificate or product approval.

Thermal mark or safety fact first?

Second lab decision on Vacuum insulated panel: heat-resistance 40 beside published thermal fact Conductivity — literacy, not a code stamp.

  1. Read the heat-resistance mark — Heat resistance on this hub is 40/100 — a thermal story, different from the fire/insulation pair.
  2. Sit one thermal fact beside it — Properties chapter lists Conductivity among published thermal rows.
  3. Heat resistance is not a fire skip — A high thermal mark does not replace named fire tests in a real assembly.
  4. Still not a building-code rating — Thickness, build-up and named tests decide compliance — this page teaches axes only.

On Vacuum insulated panel, heat 40 and Conductivity are a second thermal/safety reading after fire vs insulation.

Editorial atlas marks. Not a code certificate or product approval.

Frequently asked questions

Is Vacuum insulated panel non-combustible?
Declared reaction class in this atlas: system-dependent; core often A1-ish, skins not. Assemblies still need resistance tests.
Does Vacuum insulated panel insulate?
Thermal mark 99/100 versus the atlas. Conductivity note: centre-of-panel λ ~0.004–0.008 (declared bands).
What is the density band?
150–250 kg/m³ panels
How is it made?
Origin story: Dewar 1892 idea; building VIPs 1990s– (Scotland / Germany / Japan).
Can it be recycled?
Circularity mark 40/100 — editorial, route-specific.
Typical melting or failure heat?
core inorganic; envelope polymer/foil
What should it be paired with?
aerogel: Solid ultra-low λ without a vacuum to lose.
Where is it specified?
Buildings, transport, energy and consumer goods — see the uses chapter.
Is the fire-performance score a building-code rating?
No. It is an editorial 0–100 teaching mark among materials in this atlas. A real wall or garment needs a named product test, thickness and assembly. This page is not a lab stamp.
When should I read insulation instead of fire?
Use the insulation pick when the question is heat flow — lining, loft, or a cold-bridge — and the fire pick when the question is how the same material behaves in flame. Both numbers already sit on this hub; they answer different jobs.
Does a high sustainability score mean I can skip fire protection?
No. Sustainability here is a relative atlas mark (growth, reuse, embodied story). Bamboo and timber can still char like wood. Fire protection stays a separate specification.
Why is bamboo missing in some languages?
A language URL is published only when the seven chapters are real prose in that language. Bamboo exists in English, Korean, Japanese, Chinese and Spanish. French, German, Portuguese and Russian stay withheld — earlier machine drafts leaked English, so those URLs are not opened.
