Profine Makes Strategic Onward SaleFollowing on from the acquisition of essential assets from the administrators of Aperture Trading Ltd, which includes the Evolve, Legend and WarmCore brands, profine Group have sold the finished window and door manufacturing facilities to Solar Norvik Ltd & Solar Calibre Doors Ltd for an undisclosed sum.

Solar Norvik Ltd and Solar Calibre Ltd are newly formed companies by the same owner / management team behind the well-established Solar Windows Ltd and Interframe (SW) Ltd businesses, which are highly regarded and successful in the commercial and trade sectors respectively.

Given the fact that profine Group are a large, global systems house, the manufacturing facilities that were bought as part of the deal have been deemed non-core and so the challenge during the lockdown period was to find a suitable partner to take on these important manufacturing units. There’s now a partnership deal for growth in place between profine and the new Solar businesses, and importantly, Solar Norvik Ltd and Solar Calibre Doors Ltd will continue to operate at the Huthwaite site.

Gareth Jones, managing director of profine UK commented: ‘It made commercial sense to buy all of the remaining assets from KPMG, the administrators of Aperture Trading, but given our group mantra of excelling in our core competences, we’ve found a reputable partner for the manufacturing facilities. I have known Carl Lewis for nearly 20 years, and I do believe that we have the perfect partner in place to take these businesses and brands forward.’

Carl Lewis, managing director of Solar Norvik Ltd and Solar Calibre Doors Ltd concluded: ‘Both the Norvik and Calibre Doors assets will fit perfectly into our current business model and we’re genuinely thrilled with the deal and partnership programme that we have in place with profine. It’s also good news for both businesses, the local labour market, for the supply chain and ultimately the customers of both brands.’
