Home > Enclosure > Cladding > Curtain Walling > Concealed grid panel cladding Kalwall Translucent Sandwich Panel System Kalwall is a highly insulating, diffuse-light-transmitting material. A matrix of glass prisms inherent in Kalwall absorbs external light levels and redistributes an interior Museum-quality day-lighting that virtually eliminates, glare, hot spots (excessive solar gain) and shadows without the need for blinds or curtains. Kalwall also maximizes thermal insulation with the resultant cost and environmental benefits.A cutting edge product development includes the Kalwall + Nanogel panel. Nanogel is made up of 5% solids and 95% air. It increases light diffusion, minimizes unwanted nuisance noise, maximizes insulation potential, is UV stable and resists moisture. When incorporated within glazing systems such as Kalwall, Nanogel creates an environmentally friendly, energy efficient, insulated daylighting system.
All day-lighting systems including walls, curtain-walls, window replacements, skylights, walkways canopies and sky roofs where controlled natural daylight is required combined with finely tuned thermal and solar controls
Kalwall can contribute to optimized energy performance as a highly insulated light transmitting system. Proven structural integrity. Demanding Fire Code Compliance. Design and Aesthetic Flexibility. System Reliability and Integrity for over 50 years.
The primary element of the Kalwall System is a flat or curved, structural composite sandwich panel formed by permanently bonding specially formulated, fiberglass-reinforced translucent faces to a grid core constructed of interlocked, structural aluminum/composite, thermally broken I-beams. Translucent fiberglass “batts” or Nanogel are added during manufacturing to maximize thermal performance.
Acoustic properties: Kalwall has an STC value between 32 and 35 Db Fire Reaction: Fire resistant properties exceeding any other translucent panels. It can be specified in USA as FM (Factory Mutual) Class 1. Meets UK B.S. Part 3 1958 External fire exposure roof test, Part 6 1981 Propagation test and Part 7 1971 Large Scale surface spread of flame test. Durability : The ASTM test methods evaluate bond integrity for tensile and shear strength to 5.2 MPa and 5.5 MPa respectively (750 psi, 800 psi). Humidity Reaction: Kalwall’s exterior face is made with innovative super-weathering and colour-fast resins the full thickness. All standard exterior faces include a permanent glass veil erosion barrier to prevent “fibre bloom” and stop condensation. Thermal : Kalwall panels for use in external glazing will meet the NZ Building codes H1: Energy Efficiency. R values are as high as 3.52 and with the optional super thermal break system will achieve an R value of 4.0.
All current Kalwall Systems standard exterior faces are full thickness, colour stable, include a permanent glass erosion barrier and a self cleaning surface. Normal rainfall will keep Kalwall free of dust and dirt. A periodic wash with soapy water and a clear water rinse is recommended.
