Renovations Keep Market for Flat Roof Sealings Stable

The market for flat roof sealings in Europe increased by 2.3% in volume in 2022. The market is expected to stagnate in 2023. The renovation sector in particular provides stable demand even in difficult times, according to a study by Interconnection Consulting.

While sales volumes rose only slightly last year, industry turnover increased by 13%. The strong price increases in this segment are also due to the fact that most waterproofing materials are by-products of petroleum, one of the biggest price drivers of inflation. Germany has the largest sales volume with 118 million square meters (as of 2022), followed by France with 84 and the Nordic countries (Denmark, Norway, Sweden, Finland) with 73 million square meters. Italy, however, is the fastest growing market in Europe, mainly due to the generous subsidies in the renovation sector.

Renovation During the Crisis

The renovation sector will be the driving force for further stable demand in the coming years, not least due to the EU’s subsidy programs in this area. This trend toward renovation will continue for the next two years. Overall, the share of the renovation sector is 55.5%. By 2024, the renovation sector will increase its share to 57.4%. The renovation sector is most pronounced in Italy, where it accounts for 64.6% of total business. In Germany and the Nordics, the renovation share also exceeds 60%. “The strengthening of the renovation segment is also a sign of an economic crisis,” explains Mario Cunha, the author of the study. From 2025, the study expects demand in the new construction segment to rise again. The residential and non-residential customer segments almost balance each other out. The residential construction segment makes up 51.4%, and non-residential construction 48%.

Bitumen Dominates

Among the product groups, bitumen is clearly in the lead with a Europe-wide share of 77.1%. This is followed by plastics, at 16.5% and elastomers at 6.4%. There are hardly any major differences between the countries. The bitumen share is highest in Italy, at 80.7%, and lowest in Austria, where it is 73.1%. However, it is expected that the market share of bitumen will decrease by about one percent in the next few years. The main companies are: Bauder, Bitbau Dorr, BMI Group, Danosa, Nordic Waterproofing, Sika, Soprema Group, Technonicol, etc.

The study examined the markets: Germany, Austria, Switzerland, Italy, Spain, France, Belgium, Nordic countries (Denmark, Norway, Sweden, Finland), Poland, Romania.

Milky Glass and Pristine Views

The European market for window and façade glass in the non-residential sector is expected to grow in volume by 2.8% in 2018, according to a new study by Interconnection Consulting. Without the fallout from Brexit, the uptrend would be even greater, but will, however, continue over the next few years, with a growth in volume between three and four percent between 2019 and 2021.

Until last year, Great Britain was the largest market for window and façade glass in the non-residential sector, but was surpassed by Germany as a result of Brexit in 2017. Great Britain was the only large European market that experienced a decline in sales, of 3.5%, in 2017. On the other hand, sales grew in Germany by 4.9%, largely due to the uptick in the non-residential sector, which flourished on account of a bull market and the continued low interest rates. Poland is the market that will witness the strongest growth between 2015 and 2021. During this time period, annual average growth is expected to be 5.7%. Spain’s average growth rate is 5.5%. The Nordics are at 3.7%, France at 4.0%, and Italy at 3.1%.

The evolving glass sector, with its tremendous improvements compared to older products, will ensure increased demand. Sales will also be boosted by the fact that “the newer, high-tech glass technologies with double and triple panes will be replacing single-pane units, thereby using two to three times the amount of glass,” explains Ernst Rumpeltes, author of the study. Heat-absorbing glass, with a market share of 81.1%, is still the clear leader among glass types, although its share has been declining due to the growing popularity of combination glass. Windows account for the largest area of application, with a market share of 37.4%, followed by curtain wall systems, with 29.9%. In the future, however, curtain wall systems will gain in market shares at the expense of windows. The market for window and façade glass is very competitive and is essentially divided among a few top companies such as AGC, Saint Gobin, Guardian, Pilkington, and Euroglass.
