Roof window market Germany: installation of roof windows and forecast to 2031
How is the roof window market in Germany developing? The dataset provides demand for roof windows in million units for every quarter from Q1/2021 to Q4/2031 – as historical market data and forecast.
Roof windows, often called skylights, sit in the pitched roof and bring daylight and fresh air into converted attics. Because roof windows are sold and fitted as complete units, the dataset counts them in units. Unlike facade windows of PVC, timber or aluminium, which have their own datasets, they form a separate, additional market. Supply is highly concentrated around one large market leader.
Demand follows loft conversions and roof renovation, with a slight emphasis on existing buildings, where attics are converted and old windows replaced. Energy upgrades of the building envelope under the German Buildings Energy Act (GEG) add momentum. In new build, volumes depend mainly on housing, with installation a few quarters before completion. Non-residential buildings play only a minor role. After the construction slump, the market is recovering moderately towards a slightly higher long-term level.
Which questions about the roof window market does the dataset answer?
- How many roof windows are installed in Germany each quarter?
- What share of roof windows goes into renovation of existing buildings, and what share into new housing?
- How quickly will volumes recover after the construction slump?
- What demand can be expected from non-residential buildings up to 2031?
Who is the dataset for?
Roof window manufacturers and suppliers of accessories such as flashings, interior linings and sun protection can plan capacity and sales. Roofers, carpenters, roofing merchants and interior finishing firms gain a basis for purchasing and order planning. Architects for attic conversions, housing companies, investors and analysts can gauge loft conversion and roof renovation potential.
Data basis and methodology
Figures cover the total market, new build and renovation, and residential and non-residential buildings. The model links completions and permits with renovation of windows and the building envelope, converting floor area into units via a fitting rate per segment that is much higher in residential buildings. Volumes were derived from stock, equipment and renewal parameters and checked for plausibility against available industry information and internal data.
Delivered as CSV and Excel files, each in German and English, with 44 quarterly values. Related datasets: Triple-glazed insulating glass, Roller shutter (front-mounted / top-mounted), PVC-U windows and all data on windows, doors and sun protection.
