Transcript of CPD 2016- GLASS AS A CONSTRUCTION MATERIAL

AS A CONSTRUCTION MATERIAL
GLASS
ARCHITECTURAL GLAZING

1. LARGER SHEET SIZES.
2. LARGER TOUGHENING PLANTS.
3. STRONGER LAMINATES (Sentryglas).
4. DOUBLE GLAZING PROCESSES.
5. ADHESIVES/SILCONE.
6. JOB SPECIFIC COATINGS.

1991
EXTENSION TO OVE ARUP'S HOUSE IN HIGHGATE- EVA JIRICNA
WHAT IS STRUCTURAL GLAZING?
A flexible bond between two stable surfaces.
SPECIFIC CALCULATIONS
- bite size
- glue thickness

CONTINUOUS MONITORING
- weather conditions
- site conditions
- batch numbers
- preparation materials
- expertise of applicator

CONTROL SAMPLES

SAFETY FACTOR
IMPERVIOUS AND WEATHERPROOF MEMBRANE
STRUCTURAL SILICONE ALLOWS YOU TO BUILD ENTIRE EXTENSIONS OUT OF GLASS
THE GLASS IS RESTRAINED BY THE BOND TO THE STEEL BRACING,
BUT THE INHERENT STREGTH OF GLASS SUPPORTS EACH LEVEL
THE GLASS SPANS THE OPENING AND THE
SILICONE BOND SUPPORTS THE DOOR FRAME
PARAMETERS:
1. Winloading- height, exposure and location.
2. U value - measurement of heat transmission
through a material.
3. g value - The amount of solar radiation allowed to
pass through the glass
4. Access - weight of units (2.5kg per mm per m2)
- crane (road closure, replacement)
5. Panel size - standard sheet = 6 m x 2.44m
- oversized sheet = 6m x 3.15m (x 200%)
DO PARAMETERS = BOUNDARIES?
LANSDOWNE COURT- RICHARD HYWEL EVANS ARCHITECTURE AND DESIGN lTD.
GLASS IS STRUCTURALLY BONDED TO STAINLESS STEEL BEAMS
THE BRIDGE SPANS 4.8 METRES AND SLOPES 1 DEGREE
SO.....WHAT'S NEW?
products
innovation
technology

STANDARD GLASS + LOW E COATING = 1.7 W/m2/K

ADD ARGON IN THE CAVITY = 1.5 W/m2/K

ADD PLANITHERM COATING = 1.1 W/m2/K

INCLUDE HEAT MIRROR FILM = 0.7 W/m2/K
SKY-FRAME
GLASS SPACERS
PUREGLAZE RANGE -frame is inside the double glazed unit- larger panel sizes and better insulation.
NANOGEL
U value 0.25 light transmittance 27%
HEAT MIRROR FILM
Greater tranparency
very specific coatings!
light transmittance of 70%
THE END - THANK YOU FOR LISTENING
KEW GARDENS 1848

INVISIBLE CORNER
POGGENPOHL - THE 4TH WALL - WATERLOO SHOWROOM
Creating transparent structures by exploring the engineering properties of the material.
USING GLASS STRUCTURALLY
U values:
1 layer = 0.7
2 layers = 0.32

g value = 37%

99.3% UV blocked

85% of external noise blocked
Can a building be sustainable if it is inherently unhealthy?
