Twin Prices

in Doors & Windows

Twin prices depend almost entirely on size and material, so a single average would be misleading. Below are the specific products we have enough purchase data to price, each with its own range.

1 of 15 twin products have enough independent purchase data to price. The rest are in our data but below the threshold we publish at.

Checking a specific twin price

To check a specific purchase, find the matching product in the table above. If it isn't listed, we don't yet have enough independent purchases of that exact item to publish a figure we'd stand behind.

How we know this

These figures come from real invoices processed through CostCrunch, not list prices or survey data. Each line is normalised to a price per unit, the top and bottom 1% are excluded as outliers, and a figure is only published once there are at least 10 purchases from 2 or more suppliers across 2 or more companies, with no single company accounting for most of them.

Check your own invoices against these prices — CostCrunch reads every line item and flags anything above market.
