Do you need assistance with doing fenestration calculations for your building? Or are the calculations forcing you to use expensive double glazing or coated glass? There are alternatives!
We can save you time and money!
Often your proposed building works better than the requirements in the SANS 10400-XA:2021. And if not, there may be a few inexpensive changes you can make to ensure that it will. Expensive glazing is often not required. And as professionals registered as ‘competent persons’ we can use certified modelling software to assist you in demonstrating this.
