The Awning Buying Guide: Everything You Need to Know Before You Buy

An awning is one of the simplest ways to add usable outdoor space to a home - shade in summer, shelter from a shower, and a bit more life out of your garden or balcony. But "awning" covers a wide range of products, and getting the wrong type or spec is an easy mistake to make. Here's what actually matters when you're comparing options.

1. Start with where it's going

The location shapes almost every other decision. A wall-mounted awning fixed above a patio door works differently to one fitted on a balcony with limited fixing points, or a freestanding awning where there's no wall to attach to at all. Before you look at a single product, be clear on:

• Whether you have a suitable wall (brick, render, timber-frame) strong enough to take fixings

• How much projection (drop-down depth) you need to actually cover the space

• Whether the area gets direct afternoon sun, prevailing wind, or sits somewhat sheltered

2. Types of awning

• Folding arm (retractable) awning - the most common type. Fabric retracts into or against the wall, extends on folding arms. Good all-rounder for patios and terraces.

• Cassette awning - the fabric and arms fold away into a fully enclosed box when not in use, protecting them from weather and UV. More expensive, but the fabric lasts longer.

• Open arm (semi-cassette) awning - fabric rolls onto an exposed bar rather than a full box. Cheaper, but the fabric and mechanism are more exposed to the elements.

• Dome/hood awning - a fixed, curved canopy, typically over a door or window. Not retractable, but low-maintenance and good for smaller spaces.

• Freestanding awning - self-supporting, doesn't rely on a house wall. Useful where there's no suitable fixing point.

3. Material: frame and fabric

• Frame: aluminium is the standard choice - rust-proof and low-maintenance. Steel is stronger but needs a protective coating to avoid corrosion.

• Fabric: acrylic fabric is the best all-rounder - it's breathable, fade-resistant, and dries quickly. Polyester is cheaper but less UV-stable over time, so colours fade faster. Look for a UV rating and water-repellent coating either way.

4. Size and projection

Measure the area you actually want shaded, not just the wall length. Most awnings project between 2m and 4m; anything larger will usually need extra support arms to stop it sagging in the middle. As a guide, a 3-3.5m projection comfortably covers a dining table and chairs.

5. Wind rating

This is the spec that's easiest to overlook and most likely to cause problems later. Awnings are rated on a wind class scale (commonly 0-3 in Europe), with Class 3 the sturdiest. If your patio catches wind - especially anywhere exposed or coastal - don't buy on looks alone. Most retractable awnings should be retracted in strong wind regardless of rating; a wind sensor (see below) automates this.

6. Wall fixing and mounting

Confirm the wall type before ordering, as fixing kits differ for solid brick, cavity walls, render, and timber cladding. If you're mounting under an eave or onto a fascia board, check the bracket is designed for it - retrofitting the wrong bracket is a common (and avoidable) installation headache.

7. Colour

Beyond aesthetics, colour affects heat and fade. Lighter fabrics reflect more heat and show less fading over time; darker fabrics look sharper but absorb more heat and can fade faster in direct sun. Frame colour is largely a design choice, though darker frames show dust and pollen more.

8. Accessories worth considering

• Motor and remote control - far more common now than manual crank systems, and necessary if you want automation.

• Wind and sun sensors - retract the awning automatically in gusts, or extend it when the sun hits.

• Integrated LED lighting - useful for evening use.

• Valance (the drop-down front panel) - can be fixed or itself retractable; a retractable valance gives a bit more headroom flexibility.

9. Budget and installation

Basic manual open-arm awnings start from a few hundred pounds; cassette and motorised systems with sensors typically run into four figures. Installation is usually straightforward for smaller manual awnings but is worth having done professionally for larger motorised systems, where correct bracket placement affects both performance and warranty.

10. Before you buy: quick checklist

• Confirmed wind rating suitable for your location

• Fabric type and UV rating checked

• Wall type confirmed compatible with the fixing kit

• Projection matches the space you want covered

• Warranty terms for frame, fabric, and motor checked separately

Getting these fundamentals right matters more than the brand on the box. If you'd like to see how PERGOLUX's awning range stacks up against this checklist, you can take a look here.

Frequently Asked Questions

What's the difference between a cassette and an open arm awning?

A cassette awning folds the fabric and arms fully into a protective box when retracted, shielding them from weather. An open arm awning rolls the fabric onto an exposed bar, which is cheaper but leaves the fabric more exposed over time.

Do I need planning permission for an awning?

Most awnings fall under permitted development in the UK, but rules vary by projection, location, and whether the property is listed or in a conservation area. Always check with your local planning authority if unsure.

How do I know what wind rating I need?

If your patio or balcony is exposed, coastal, or catches strong prevailing winds, look for a Class 3 rating and consider a wind sensor that retracts the awning automatically in gusts.

Can an awning be fitted without a wall?

Yes - freestanding awnings are self-supporting and don't require a wall fixing, making them a good option where there's no suitable structure to attach to.

How long does an awning fabric last?

A quality acrylic fabric with good UV resistance typically lasts 10-15 years before it needs replacing, depending on sun exposure and how well it's protected (a cassette design extends this considerably).
