About Us

MB Fibreglass ( McConnell Brothers ) has traded in Northern Ireland for over 50 years. Originally opened by two brothers Laurence & Roy McConnell in 1972 in Newtownabbey,  the business rapidly grew with manufacturing boat hulls, car parts and fibreglass sheets. As the business began to distribute more materials they moved to Belfast where they traded for another 40 years. 

With online expansion in 2009 the McConnell Brothers traded as MB Fibreglass, with an increased range of products and stock levels it rapidly established itself as one of the main online retailers for composite and moulding materials.  With customers now ranging from film studios, prototyping, formula 1 teams to chocolatiers, our selection of casting products is among the most varied online and in-store. Our rapid dispatch of products ensures the most time critical projects can depend on our service.

While many things may have changed over the last 50 years in the business we strive to maintain the very high level of customer service and satisfaction started by the original brothers, with increasing staffing levels and additional storage we aim to continue to customer based ideology.
