  2. Glass-to-metal seal - Wikipedia

    en.wikipedia.org/wiki/Glass-to-metal_seal

    Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...

  3. Curtain wall (architecture) - Wikipedia

    en.wikipedia.org/wiki/Curtain_wall_(architecture)

    The wall transfers lateral wind loads upon it to the main building structure through connections at floors or columns of the building. Curtain walls may be designed as "systems" integrating frame, wall panel, and weatherproofing materials. Steel frames have largely given way to aluminum extrusions.

  4. Insulated glazing - Wikipedia

    en.wikipedia.org/wiki/Insulated_glazing

    A typical installation of insulated glass windows with uPVC frames. Possibly the earliest use of double glazing was in Siberia, where it was observed by Henry Seebohm in 1877 as an established necessity in the Yeniseysk area where the bitterly cold winter temperatures regularly fall below -50 °C, indicating how the concept may have started: [2]

  5. Sealant - Wikipedia

    en.wikipedia.org/wiki/Sealant

    Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal. In building construction sealant is sometimes synonymous with caulk (especially if acrylic latex or polyurethane based) [ 2 ] and also serve the purposes of blocking dust, sound and heat transmission.

  6. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    Glass-glass evacuated tubes are made with two borosilicate glass tubes fused together at one or both ends (similar a vacuum bottle or dewar flask). The absorber fin is placed inside the inner tube at atmospheric pressure. Glass-glass tubes have a very reliable seal, but the two layers of glass reduce the amount of sunlight that reaches the ...

  7. Vacuum insulated panel - Wikipedia

    en.wikipedia.org/wiki/Vacuum_insulated_panel

    A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction , refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials.

  9. Firestop - Wikipedia

    en.wikipedia.org/wiki/Firestop

    A firestop or fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fire-resistance rating of a wall or floor assembly intended to impede the spread of fire and smoke. [1]
