Nu-Glaze® came about as a frustration-born solution by the owner/innovator, Johan Otto. An alternative to the failing clay putty caulking and wood beadings on his house's windows were sorely needed, after replacing it for the 3rd time at great costs and hassles. The minimum criteria was to find a hard, tough, yet easily workable non-metallic material offering a 45° slope to finish and protect the 90° glass-frame junction.  And, it must be still be cost-effective in relation to clay putty. 

Crude hand made models to fancy 3D prints and countless hours later, the current profiles ticks all the boxes and some more. Costs & pricing, ease of application, manufacturing, safety and security, versatility and aesthetic appeal were achieved to boot.    The patenting process was initiated in 2007 and soon all the major international markets were covered. Product development then started with all earnest and in 2010, Costi Buccimazza got involved to further the development and facilitate roll-out into the market place. This co-management model works well by combining skills, knowledge and experience. Johan, relying on his B.Sc. knowledge for the technical aspects as well as 25 years in retail for marketing and sales, while Costi, (B.Comm Hons.) added his keen business acumen and financial support. 

UV testing and waterproofing tests followed until the product was ready. The first commercial work was done in 2012 on a housing project in Vryheid, KZN, where it still fulfill it's duty , in original condition, to this day, despite conditions ranging from tornadoes to scorching African sun.   a DIY project done in 2021 in Langebaan, Western Cape, less than 200m from the sea and exposed to the harshest of elements, tells the same story and looks as if done yesterday.

Soon, renovation projects in UK, USA, Australia, New Zealand, Malawi, Kenya, Zimbabwe and locally in South Africa followed, with resounding success. One of the best moments were the use of Nu-Glaze® on an almost 300 year old building in Franschoek, Western Cape. This proved it's original frame preserving feature on heritage buildings.

Through it's Reach & Teach program, Nu-Glaze® actively seeks to empower and launch as many Approved Installers as possible - creating more self reliant business owners rather than merely creating jobs.   Alongside this approach, we also supply and technically support the glaziers and building/painting/renovation contractors and companies.


We have developed a range of products making the glazing of steel, wood, concrete and polycrete window and door frames quick and easy, leaving you with an exceptionally neat finish. Nu-Glaze is this new, unique cost saving solution helping architects, specifiers, building consultants, renovators, housing department officials maintenance managers, engineers, contractors and DIY’s enthusiasts alike! Clay putty has been around for hundreds of years and has never been challenged. Clay Putty typically has a short life span, difficult installation and a slow curing rate. Wooden beading also has numerous shortcomings namely rotting, swelling, constant need of maintenance (sanding and painting), which, if not done, will ruin the wood’s warm, natural look and feel. The internationally patented Nu-Glaze® uPVC - with highest possible ultra high anti UV properties - aims to counter these problems and while simultaneously achieve a higher level of safety and security. Nu-Glaze SANS 10400-XA compliance. Nu-Glaze® complies with SANS 613 (SABS and AAAMSA tested), and achieved a A3 rating, A1 being the minimum requirement.


Double glazing as well as additional profiles and sizes are planned and already patented. With the current available solutions, one can glaze with glass from 2mm up to 6,38mm including safety glass and on most available platforms. We also offer custom once off production with the latest technology at our disposal, from producing drawings to 3D prints, to actual product sampling can be facilitated. With the aid of a special construction-grade neutral cure (what does that mean Curing by means of absorbing moisture vs the evaporation of Acetic acid as per Acetoxy products – which can be harmful to the frames) silicone, sealing and adhesion is facilitated in conjunction with a u-clip system for steel windows and a pin down inside corner piece for the wooden window, being the mechanical fastening if needed. We also facilitate training and assist the trainees to develop their own, sustainable business in their communities. See our Reach & Teach section. The company is currently owned and operated by its inventor, who has a passion to see his innovation create a difference in people’s lives, from home owners to installer, contractors, specifiers, retailer and wholesalers.
