Curtain Wall Market is Facing Difficult Times

The six most important markets for curtain walls in Europe (Germany, France, Spain, Great Britain, Italy and Poland) posted a decline in sales of 0.6% in 2019. Follwoing the most likely scenario, the COVID crisis will cause a sharp drop in sales this year (-4.5%). But even after that, the market will find it very difficult to get going, as shown in a study by Interconnection Consulting.

Ray of Hope in Two Years

The decline in sales across Europe – in the most likely scenario – will continue until 2022. While sales in the previous year were around 21.8 million square meters, they will most likely only make up 19.8 million square meters in 2023, as a low demand for new investments in the construction industry is expected until 2022. The developments caused by the crisis in the individual countries are all different. Italy will experience the largest decline in 2020 in the most likely scenario (-12.2%), followed by Great Britain (-9.9%), although it can be said that for both countries this is simply continuing their decline in sales. By far the largest market, Germany, will lose 3.8% of its sales volume this year, ending a long upward phase. On the other hand, France and Poland will actually end 2020 with a slight increase in sales. However, sales volumes in these countries will also decline sharply in the following years due to the consequences of the crisis.

Trending New Materials

In terms of materials, aluminum-glass holds the majority with a share of 82.6%, followed by steel-glass. While the steel segment continues to lose shares, aluminum will continue to expand its market position. However, the strongest trend can be seen in other materials, such as wood-aluminum or wood-glass systems. Alternative elements such as stone, ceramic or plastic are also being used more and more frequently.

Housing Construction Will Collapse

The market share of property construction is 89.5%. With almost half of total sales, the office segment is the strongest customer segment. This is followed by retail (18.7%) and industry with 14.1%. The greatest losses are expected in residential construction, whose sales will fall by 8.3% this year. Around three quarters of the sales volume is used in new construction.

Curtain Wall Industry in Germany Will Only Recover Slowly

Sales of curtain walls increased in 2019 by 4.2% to 7.2 million square metres. In 2020, sales are set to decline by 3.8% due to COVID-19, as shown in a new study by Interconnection Consulting. The industry will only slowly recover from the effects of the pandemic by 2023.

In 2020, due to the consequences of the shutdown, sales will most likely decrease to 6.9 million square meters, as the study shows. By 2023, this value will increase slightly, up to 7.0 million square meters. The crisis is set to end the continuous growth of the industry in recent years. The industry recorded an increase from 6.0 to 7.2 million square meters in the five years between 2014 and 2019.

Wood on the Advance

Aluminum is the dominant product group with a share of 78.5% and is not set to lose any of this majority in the future with above-average market growth. Lower growth and thus falling market shares can be expected for steel-glass combinations. The strongest upward trend is the wood-glass combination. „The advantages of the trend-material, like sustainability aspects and easy handling contribute to the rise of this material group. In addition, wood is renewable and resistant and has very good thermal insulation, ”explains Daniel Kollar, the author of the study.

Trade and Industry are Catching Up

The strongest sales segment by far for curtain walls is the office segment with a share of 43.2%, followed by the retail segment with 21.5% and industry. Only then comes the residential segment, which so far only accounts for 12.3% of total sales. This proportion will not increase until 2023. On the contrary, the residential segment will continue to lose shares, while the retail and office sectors will see the largest growth rates until 2023.

Rainscreen Cladding Facades with Further Growth

The facade cladding market for Rainscreen Cladding Facades in Europe + USA (Austria, Belgium, Denmark, Finland, France, Germany, Italy, Norway, Poland, Russia, Slovakia, Spain, Sweden, Switzerland, Czech Republic, Netherlands, United Kingdom, United States) increased its sales by 4.0% in 2018, with some significant differences between the different countries. Overall, Interconnection Consulting expects average annual growth of about 4-5% (4.1% in volume, 5.6% in value) in a new study by 2021.

Development Consistently Positive

A closer look at the markets examined, shows that overall sales figures have risen steadily in recent years. While Austria only grew by 2.1% in 2018, the Czech Republic achieved growth of a respectable 7.4%. Germany achieved growth of 5.0% in volume in 2018, outperforming Italy (+ 4.5%) and the United Kingdom (+ 1.6%), shaken by the Brexit uncertainties. Despite the growth and the advantages over the whole lifecycle of the facade (energy-saving measures, reduced maintenance work, uncomplicated dismantling, etc.), the necessary higher initial investment in the acquisition of Rainscreen Cladding (compared to conventional facades) slows down growth even more. Thus, depending on the type of building, there is also substitution with industrial facades, ETICS, sandwich panels and curtain wall facades. The trend towards more daylight, which favors curtain walls, remains another obstacle. In addition, non-residential construction was not able to grow as strongly in most countries as residential construction, where Rainscreen cladding facades still tend to be under-represented, as compared to non-residential construction (office buildings, government institutions, commerce, others).

Wide Range of Cladding Materials

A Rainscreen Cladding façade can be defined as a multi-layered exterior wall construction. Here is the outermost layer that serves to protect against driving rain. The construction consists of the facade cladding, the ventilation zone, the insulation and the substructure. The cladding may consist of various shapes and types of panels /bricks / sidings, made out of: aluminum, steel / metal, wood, natural stone, fiber cement, HPL, ceramics, concrete / stone, vinyl, plaster base plates, etc; Aluminum (composite) is one of the most popular cladding materials, accounting for 27.3%, with fiber cement (17.4%), metal, ceramics and “other materials” being among the most important groups of materials.

New Construction Stronger Than Renovation

In the residential segment, the rate of Rainscreen Cladding Facades, is usually lower than in the non-residential sector in most of the countries surveyed. Italy accounts for only 9.6% of the lowest share, probably due to the high costs, while countries such as Denmark and Finland account for an above-average proportion of the residential segment, while most other European countries having a share of the residential sector of ¼ to a ⅓ of the total Rainscreen cladding market.
A very dominant position occupies “new construction” compared to the “renovation” area. In the Czech Republic, for example, 81.5% of newly installed Rainscreen cladding facades are installed on the new building, with Austria not far behind with just under 80%. The end of the spectrum is formed by Switzerland and Spain, with a significantly lower share, where the renovation sector is much more pronounced.

Leading manufacturers of cladding materials / panels that are installed as a Rainscreen cladding façade, include companie like Etex, Cembrit, Swiss Pearl, Trespa, 3A Composites, Fundermax, Rockpanel, Sto, Resopal, Agrob Buchtal, Prefa, or Eternit, to name a few. Closely related to the industry are also manufacturers of facade fastening systems (anchors, substructures, facade dowels, adhesives and the like) such as Hilti, Fischer, Schock, Sika, Ejot, Sto, BWM, Systea, Allface, Nauth, etc. and insulation manufacturers such as e.g. Rockwool, or Saint-Gobain, etc.

Despite Increased Prices Sandwich Panels Still in Demand

The most striking development in the market for sandwich panels in recent years was the extraordinary price increase in 2017, caused by a production shortage in PIR and PUR raw materials.  For the countries analyzed (Germany, Austria, France, Italy and Poland)  the market was valued at 2,1 Bio Eur  in 2018 and projected to expand over the forecast period at an annual compound rate of 3.2% to reach more than 2.3 Bio Eur  in 2021. Despite the existence of alternatives in facade construction and thermal insulation, the demand for sandwich panels has been rising every year.

Germany and Italy are by far the biggest market for sandwich panels  in Europe which are set to increase at an annual compound growth rate of around  2.1% and 3.3% respectively until 2021. Synthetic foam core panels still make up the majority of the market, accounting for 26.9% share, but mineral wool core segment has a higher growth expectation expanding at a compound annual growth rate of  3.3% from 2017 to 2021. The latter’s price disadvantage has all but disappeared in the last two years. The trend in favor of mineral wool is due to strengthening of fire protection regulations. At the same time, mineral wool-cored panels require the use of thicker panels caused by higher thermal conductivity.

Relatively simple installation

The cover sheets are overwhelmingly made up of steel. Corrosion protection technology has improved massively, so aluminium’s lighter weight is now it’s only selling position. When it comes to insulation thickness, the thick panels (>100 mm) will certainly go up due to mandatory compliance with energy standards. This segment is set to grow on average by 4.4% annually. Interconnection Consulting expects the market to keep a stable growing pace due to sandwich panels’ relatively short installation time and consequently cost optimization, improved properties and highly dependence on growing number of new manufacturing objects, warehouses, storage and those which need renovation.

Dynamic economy in Southeast Asia is making a quick comeback

The market for curtain walls in the ASEAN countries (Singapore, Malaysia, Indonesia, the Philippines, Vietnam, Thailand) is bound to plummet by 9.6% this year due to the COVID-19 crisis. However, the market will recover very quickly and by 2022 will have already exceeded the pre-crisis market volume, as a new report by Interconnection Consulting shows.

Good conditions for a quick rebound

The integration of the ASEAN region into the global industrialization process, as well as into global tourism and the construction sector, offers strong impulses for the construction industry. The wave of urbanization is also a strong driver of the construction industry and is even more dominant in the ASEAN countries than in Europe or the USA. These factors are decisive for the construction industry and thus also the market for curtain walls to keep going faster than e.g. in Europe.

Vietnam benefits from the trade war

Indonesia and the Philippines are not only the most populous ASEAN countries, but also the most dynamic markets, recording an astounding growth level. Indonesia is also the largest market for curtain walls in the ASEAN region with a share of 32.5%. Vietnam benefits from the trade war between China and the United States, as many foreign factories move from China to Vietnam to avoid trade tariffs. Therefore, despite Corona, the industry growth in Vietnam will average 2.4% annually over the next few years until 2022. By contrast, while Singapore and Thailand have poorer growth prospects, Malaysia has stable growth prospects.

Smart working instead of office presence

The most important material type is reportedly aluminum glass, with a lion’s share of 84.3%. Above all, it is the cost efficiency that speaks for aluminum and against e.g. Steel / glass, which only has a market share of 8.0%. The largest application area for curtain walls is office buildings with a share of 32.8%. In contrast to many other regions, the residential sector (e.g. apartments) remains a very important segment for curtain walls in Southeast Asia at 27.2% of the total. There could also be shifts in favor of co-working spaces in the future. “There will be more smart working and it is likely that there will be less office space for the same number of employees,” stated Vito Graziano, author of the report. Furthermore, it can be expected that the new development of hotels will only progress very slowly in the next few years due to setbacks in tourism.

Downward trend in raw material prices strengthens margins

Overall, the renovation sector makes up a small chunk of the market with around 15% of the total volume. Conversely, new construction makes up for a share of 85.7%, and this trend will not change in the next few years. But the corona crisis also has immediate positive effects for producers: in the wake of the corona crisis, raw material prices are on a downward trend worldwide, which should strengthen the margins of facade manufacturers overall.
