"As 2013 progressed, virtually all of the factors that had previously suppressed the growth of the windows and doors market materially changed, and a period of sustained growth can now be expected. The most significant factors that did not are the availability of credit, but this too will slowly ease over the next few years; and high penetration levels of double glazing, which suggested market saturation had occurred prior to the economic downturn."

- Terry Leggett, Senior Industrial Analyst

A level of pent up demand for second (or more) round replacements has arisen in the subsequent flat economy, which combined with renewed house price inflation and fuel price inflation continuing to outstrip general inflation means that demand for double glazing and treble glazing will demonstrate steady growth. At the same time conservatories have proved to be a cost effective method of increasing the living space of existing properties, and the market is so established that it has become lifestyle more than fashion.
