Visual Blog: Kalwall in the Retrofit Market

Posted by Kalwall in Blog, Retrofit on 11/02/2017

The design challenges facing architects and builders when renovating older buildings are considerable from increasing energy efficiency, to navigating inherited structural and building code changes. Here are five projects highlighting how such issues were solved, and illustrate some incredible transformations.

Charles H. Shaw Technology & Learning Center

Chicago, Illinois, U.S.A

Farr Associates converted a century-old industrial powerhouse into a modern learning center filled with natural diffuse daylight, while preserving key structural elements, including brick walls and floor tile, as well as some of the original machinery.



Buurtsporthal Parkloods

Antwerp, Belgium

This neighborhood sports park utilized Kalwall for its ability to provide balanced daylight and line of sight for athletes inside. The translucent panels help ensure the safety & security of athletes with visual privacy and impact resistance. As an extremely lightweight option in retrofit design, Kalwall offered large clear spans and accommodated the existing brick walls of a historical munitions factory.

Hermans & Co


Crouch End Picturehouse

London, UK

VertiKal™ panels were factory unitized with sash, for a sleek, energy efficient recladding of the Crouch End Picturehouse – a renovated 1950s factory building. The Panter Hudspith design, which won three industry awards, uses the curtainwall to create gentle backlighting at night as a visual marquis.


1060 Redwood Office Building

Mill Valley, California, U.S.A.

An ordinary commercial box building was transformed by adding top-lighting from Kalwall skylights. This modern workspace is now filled with natural, diffuse daylight, creating an ambiance that ensures a healthy work environment that boosts productivity. The OSHA fall-through compliant (`man-safe’) translucent skylights enable effective and easy maintenance without the need for safety cages.

Featherstone High School

London, UK

Kalwall window replacements were an economical energy upgrade for an old school building that was failing due to decay and ingress of water. The highly-insulated translucent sandwich panels bathe the classrooms in diffuse natural daylight while reducing HVAC and artificial lighting costs. Unitized construction allowed for fast installation and minimal disruption to school operation.
