Brand launches and business growth with Dekko
Dekko wanted to move upmarket. A Residence Collection 9 launch campaign in 2013 began a relationship that went on to introduce Räum and Infinity, support trade customers and explore new markets. During the partnership, Dekko grew from £6 million to £25 million in revenue.

business growth during the partnership
More than a decade of work, including brand launches and entry into new markets.
The first campaign: Residence Collection 9
Dekko was selected as a launch partner for Residence Collection 9, a premium uPVC system for the high-end residential market. Its directors wanted to reach 100 window sales a week.
Purplex developed a targeted email campaign using Insight Data’s industry information. It generated 150 high-quality leads. The business tracked the repeat custom that followed over the years and attributed £1.5 million in revenue to that original campaign.
Launching Räum and positioning Infinity
Entering aluminium in 2015 gave Dekko an opportunity to reach a new part of the market. It needed a product brand customers could recognise and a launch that gave them a reason to take notice. We developed Räum and introduced it through a teaser campaign in trade publications, paid advertising and social media.
Dekko’s investment in a graf welding machine created another opportunity. Its smooth corner weld was a manufacturing difference customers could see. We helped develop the Infinity brand around that feature, making it easier for the business and its installers to explain what distinguished the product.
Supporting trade customers and new markets
The ongoing strategy combined press coverage, direct mail, social media and video, including factory tours, staff profiles and product showcases. Homeowner enquiries were passed through to Dekko’s trade customers, supporting those relationships as well as demand for the product.
Purplex also supported Dekko’s FIT Show presence through stand design, literature and follow-up marketing. Andrew worked with Kurt on the business strategy and opportunities in housebuilding and architecture. The work developed as the company’s ambitions and routes to market changed.
A business that grew from £6 million to £25 million
During the partnership Dekko grew from £6 million in revenue to £25 million, launched multiple brands and entered new markets. In 2023 it was acquired by Inwido, Europe’s largest window group.
The work developed from one product campaign into advice and delivery across brands, trade relationships and new markets. Kurt Greatrex's account explains the contribution he believes Purplex made to Dekko's growth.
