Frequently Asked Questions (FAQ)
Measurement
Q1: Do you provide on-site measurement services in Australia?
A: No, we do not provide on-site measurement services at this stage. Customers are required to measure the window or door opening themselves.
Q2: What measurements should I provide?
A: Please provide the opening width × height × thickness in millimeters. This is the rough size of the hole in the wall, not the frame size.
Q3: I’m not sure how to measure—can you help?
A: Yes! Please refer to our Measurement Guide and Video Tutorial for step-by-step instructions. You can also email us for assistance.
Wall Structure & Deductions
Q4: How does wall structure affect product size?
A: Our team will adjust your provided measurements based on wall type:
Timber walls: More flexible, require smaller deductions
Concrete walls: Less tolerance, require tighter fit control
We will handle this deduction internally and reflect it in the drawing.
Q5: When should I tell you whether I have a timber or concrete wall?
A: Please inform us at the time you submit your measurements.
Wall type affects product sizing, so we need this info before preparing your drawing.
Drawing & Production
Q6: Will I see a drawing before production?
A: Yes. We provide a technical drawing showing final sizes and structure for every order. You must confirm the drawing before we begin production.
Q7: Can I change the size after confirming the drawing?
A: No. Once confirmed, the drawing becomes the production reference. Please review carefully before approval.
Installation & Support
Q8: Do you offer installation service?
A: Currently, we do not offer on-site installation.
However, we provide:
Detailed video instructions Illustrated manuals Online support
Q9: Can I install the product myself?
