Things to consider before starting...

How do I know if my window has enough depth for a recess fit?

For a recess (inside) fit, your window frame needs sufficient internal depth to house the blind and its brackets without obstruction. Measure the depth from the front of the frame to the glass, ensuring there are no handles, winders, or tracks in the way. If space is limited, a face fit may be the better option.

What if my opening isn’t perfectly square?

Most openings aren’t perfectly square – which is completely normal. That’s why we recommend measuring the width and height in three different places. For recess fits, use the smallest measurement to ensure the blind fits neatly within the space.

How much overlap should I allow for a face fit?

For a face (outside) fit, we recommend allowing at least 50–100mm of overlap on each side where possible. This helps improve light control, privacy, and overall coverage while creating a more balanced look.

Should I round my measurements up or down?

Always record exact measurements to the nearest millimetre and avoid rounding up or down. Providing precise numbers ensures your blind is manufactured accurately for the best possible fit.

Warranty Disclaimer

Outdoor blinds and folding arm awnings are designed to provide shade and comfort, but their wind resistance varies depending on size, projection, mounting height, and the environment, for example coastal, exposed, or sheltered areas.

As a general rule, larger blinds and awnings handle less wind than smaller units. The greater the fabric span or projection, the lower the safe wind tolerance.

To protect your investment and ensure warranty coverage:

Always retract blinds and awnings during storms, strong winds, or when away from home.
Products should not be left extended in wind conditions that cause visible strain, for example fabric pulling, frames flexing, or rattling.
Each installation is unique. It is the client’s responsibility to assess local conditions and retract products before damage can occur. MIY Outdoor accepts no responsibility for damage caused by wind exposure beyond reasonable conditions for the size and environment of the product.
