The easiest way to buy aluminium is to shop by size. Enter the width and height of the opening you need to fill, and the tool below shows every window and door that comes in a standard size to cover it — no aluminium-system codes or panel jargon to decode.
How to shop by size
Most people know the hole they need to fill, not the product name. Shop by size works the way you actually measure:
- Enter your opening — width and height in millimetres. Rough sizes are fine.
- Pick what you want — windows, sliding, folding or hinged doors, or leave it on “anything”.
- See what fits — every product with a standard size that covers your opening, with a “best fit” size, price and image.
What you can shop by size
The tool searches the full made-to-order range:
- Aluminium windows — top-hung and more.
- Aluminium doors — sliding, folding, stacking, hinged and pivot.
- The full shop — browse everything by category.
- Cut-to-size glass — panes to your dimensions.
Made to order, sized to your opening
Every window and door is manufactured to order, so the standard sizes are a starting point — if nothing lands exactly on your measurement, we can make to your precise opening. When you shop by size and see a product that fits, you can view it in the shop or request a made-to-order quote for the exact dimensions.
Why shop by size beats searching by name
Aluminium product names carry a lot of jargon — panel configurations, system numbers, opening codes. Shopping by size skips all of that. You describe the space, we show the products that fit it, and you compare by price and glass in a couple of taps. It turns a confusing catalogue into a simple, visual shortlist.
Who shop by size is for
Shop by size is built for the way real customers buy. Homeowners replacing a window know the reveal they need to fill, not whether it is a top-hung or a casement. Builders and renovators work off a schedule of openings. Property managers pricing a job just need to know what fits and what it costs. In every case, the opening is the starting point — so that is where the tool starts too.
Behind the scenes, each result is matched from the actual product catalogue: the tool reads every standard size we offer and returns only the products that come large enough to cover your opening, ranked so the closest fit shows first. Because everything is made to order, you are never limited to those standard sizes — but seeing what already fits is the fastest way to shortlist, compare prices and understand your options before you request a formal quote.
It is the same idea as our shop, made simpler: instead of scrolling categories and decoding names, you shop by size and let the products come to you. Enter a couple of numbers, and instead of guessing which product name matches your opening, you get a clear, visual shortlist of everything that genuinely fits — priced, pictured and ready to compare in seconds.
