Measurement methodologies vary based on your project typology—whether it involves a renovation/replacement, a structural extension, or a brand-new architectural build. Factors such as wall construction type (e.g., brick veneer, double brick, or timber framing) also directly dictate how clearances are calculated. We highly recommend having your project builder or licensed installer take the site dimensions, or you can send us your architectural plans. Our technical consultants will gladly guide you through the exact measurement matrix required for your specific opening types.
