Museums

Introduction

Museums are massive time capsules with space for us to walk through.  Museums exhibit precious, unique and sometimes fragile objects.  Often encasements are used that provide for full or partial viewing of the object.  These encasements often need to have near invisible protection from dust, moisture, UV radiation, physical touching, accidental impact and intentional vandalism or theft.   Museums are public buildings with high traffic areas containing objects that sometimes may not be easily moved.   Interior and exterior glazing of a museum often requires enhanced performance glazing.

Facades and skylights as well as internal doors, walls and encasements are being designed using glass extensively in the planning of museums. Precautions must be taken to avoid any risk of injuries in case of glass breakage. Acoustic insulation of the façade for internal comfort, the use of colored glass for segmenting display areas and controlling incident light, UV screening for fade control and the use of translucent glazing for skylights are design needs for museums.

Which products fit in?

Eastman has experience with multiple interlayer products being used in the design of the glazing for museums, including:

  • Saflex Clear, the conventional PVB interlayer can be used for:
    • ​Safety: in case of glass breakage from human or accidental impact, the shards of broken glass will remain adhered to the interlayer providing a reduction in cutting or piercing injuries.  With properly glazed laminated glass in a framing system, fall through protection may also be provided.
    • Storms:  laminated glass with adequate interlayer thickness is capable of thwarting wind-borne debris from penetrating the façade and subsequently allowing destructive internal pressurization in severe windstorms such as tropical cyclones, typhoons and hurricanes.   The ability of the interlayer to contain the glass shards after breakage has been demonstrated to contribute to enhanced glass retention during seismic activities as well. 
    • Security: a laminated glass configuration can be incorporated into a system to provide a sufficient level of protection against man-made intentional attacks, including vandalism and burglary, explosion resistance and ballistic assault.

 

  • Saflex Acoustic is an engineered tri-layer interlayer that provides enhanced sound damping between 1000 – 4000 Hertz (Hz) as compared to conventional PVB interlayer.   The enhanced performance may allow the glazing construction to be designed using less air space and/or thinner glass to achieve the same sound reduction rating versus conventional and historic practices.
     

  • Saflex Solar, a solar absorbing PVB interlayer, brings improved the solar control by reducing solar heat gain versus clear and conventional laminated glass without coatings.  Saflex Solar can also be incorporated into single unit laminated glass with low-emissivity hard coatings or into insulating glass units (IGU) with or without low-emissivity glasses.  
     

  • Vanceva® Earth Tones collection and Vanceva Colors interlayers bring forth the possibility of using a large range of color in a façade or as interior glazing without having to increase glass thickness to achieve color intensity, be delayed waiting for colored glass campaigns or ordering large quantities of custom colored glass. Both products provide the flexibility to customize or modify and improve the aesthetic of the façade.
     

  • Saflex Structural PVB interlayer can be used in laminated glass configurations targeted for floors, stairs, fins, balustrades, guards and canopies.
     

  • Saflex High Protection (HP) and Saflex Storm interlayers can be used when enhanced protection from tropical cyclones, typhoons and hurricane force winds with windborne debris are needed.
     

The various types of Saflex and Vanceva interlayers mentioned above can be combined between two pieces of glass or in the same glazing configuration to improve the overall performance of the glazing system and contribute to the optimum performance of the museum application.
