The Trend Towards Paint Refinishing of PVCu Windows

The replacement fenestration market was for many years a straightforward choice for its customers based on the material from which the window was made. Timber was preferred as the authentic choice with its original detailing, while aluminium emerged as the contemporary alternative with novel design features and low maintenance requirements. PVCu then grew rapidly to take the lion’s share of the market as the energy efficient solution at a much lower price point and with maintenance-free advantages.  However, with chunky profiles in a standard white plastic finish and a few wood grains, the aesthetic appeal of PVCu was never its strong point. It was strictly the price, energy efficiency and low maintenance requirements that drove its early success.


The market has of course evolved to become far more complex in recent years, providing customers with almost unlimited choice as performance and design features have converged across all substrates and price differentials have shrunk. PVCu has significantly addressed its weaknesses in terms of design detail and appeal, while aluminium has improved its energy efficiency and price competitiveness. All window types now strive to meet the same energy efficiency standards and offer very similar performance warranties.

Overall, the basis for differentiation between base materials has substantially been reduced as the breadth of design choices, features and finishes has expanded across them all.


This explosion in product variety is the industry’s natural response to a significant shift in the nature of the replacement window market. These days the motivation for window replacement is far more likely to be a house ‘make-over’ rather than simply improving its energy efficiency. This clearly places the window’s look and style as the key feature upon which the purchase decision will be made.  With other features being largely comparable, aesthetics is replacing material choice as the main basis for competition in the market. The final look of a finished window is formed from a combination of the window design, the profile and weld joint details and the hardware components selected but perhaps above all else, is most influenced by the choices made for both colour and finish.


The key question for PVCu fabricators is therefore how to effectively respond to this fundamental shift in the market when their traditional operating model is based on offering their products in a limited range of standard colours from stock profile. Clearly they require a far more flexible and responsive make-to-order manufacturing model if they are to succeed in a customer-lead market.


As you might expect, it is the larger PVCu fabricators that are leading the way in evolving their production operations to meet this challenge. By introducing a paint refinishing process into their manufacturing operation they can immediately move to a make-to-order offer to meet any colour and finish requirement requested by their customers.


In our experience, once established, paint refinishing naturally becomes the preferred process to deliver all ‘special colours’ as pricing and lead-time are significantly improved versus use of pre-foiled profile. The fabricator can also readily offer all required ancillary components in the same finish as a much valued, complete parts service to the installer.  The benefits in terms of stock levels and working capital are also significant. The required capital investment is modest and offers an attractive return based on the available savings. Given all of its advantages, the trend towards adopting paint refinishing as a core process looks set to continue across the industry as the ability to offer a wide range of colour and finish choices becomes a critical success factor for all of its participants.
