If you are to buy a patio awning, you will realise that there are several models with different specifications available.
Basically there are 3 types of awnings that are in the market today:
Standard Patio Awnings
These usually consist of an aluminium roller that has brackets fitted on both ends and a gearbox that has a winding handle hook. These components are assembled into a square steel bar which is then attached to wall brackets.
Most patio awnings that are 3 metres wide have at least 2 wall brackets while those that are 4 metres wide will have at least 3 wall brackets. Standard patio awnings are cheaper since they are relatively simple to construct. However, they do not have a weather cover combined into the fabric, so whenever the awning is wound the fabric is exposed to elements that cause it to wear faster.
To circumvent this problem you can buy weather covers which slip over the wound in awning (more like a patio furniture cover). These will prove very valuable to your awning as they will maintain it clean throughout the winter so they are a good investment.
Half Cassette Patio Awning
The half cassette awnings consist of a three quarter round aluminium tube substantially constructed to house the aluminium roller tube and canvas inside. They are usually available either with or without a motor and some of them have remote controlled functionality. Therefore they are much advanced as compare to standard awnings and last for several years.
These awnings have covers that are fully protected from elements by the half cassette body and therefore do not fade or get mould unlike the standard awnings. Furthermore, the arms these half cassette awnings are made from more substantial sized aluminium making them more robust. They are therefore much heavier due to the extra aluminium used for their construction and this makes their cost more that twice that of standard awnings.
If you are worried about the strength of the supporting wall, you may want to avoid the half cassette awnings because of their increased weight. However, you get around this problem by securing wall bolts into the wall by adding a 2-part epoxy glue (especially for insulation block type walls). This glue should be left to harden for more than 6 hours before bolting the wall brackets and hanging the awning.
Full Cassette Patio Awnings
These are fully enclosed awnings where the arms, roller and fabric are fully protected inside the closed cassette after the awning has been retracted.
The full cassette awnings are recommended for protection in installations that are prone to elements and they are the only awning type that offers full protection to the fabric cover. Because of this protection the covers usually maintain them clean and fresh as if new condition for several years if the retraction is done properly.
Retractable Awnings (Rollerflex Auckland) delivers and installs several varieties of full cassette awnings depending on the purpose the awnings are to be used for.
These awnings have either one of the two types of operating gear. It can be a chain driven awning or gas powered piston awning.
As with any other equipment, you get what you pay for. The very cheap awnings in the market are specifically manufactures to hit those low prices. They have several shortcomings such as the covers not being waterproofed or the covers not having an anti-UV protection. This will translate into the fabric fading really fast. And for the good quality awnings, all metal parts except the hook are coated with powder but for the cheap ones the coating is very thin which results to the metal frame rusting and corroding.

Retractable awnings are a great way to protect yourself from the harsh kiwi sun. The covering attaches to an exterior wall of your home or building to provide shade and reduce the amount of light filtering in.
You’ll be surprised how many places retractable awnings can be used in. You can place them above windows and doors or use them to cover a courtyard area. They can be attached to walls, ceilings or under eves.
