What SEALED TIGHT SOLUTIONS LIMITED does
Sealed Tight Solutions Limited is a privately held UK building products company headquartered in Ryton, Tyne and Wear. It supplies intumescent, smoke, and acoustic sealing components for timber, uPVC, and composite doorsets, alongside complementary ironmongery (letterplates, hinges, hinge pads) and FD30/FD60 glazing systems. Its core technical offering centres on fire-rated intumescent seals tested to FD30 or FD60 integrity standards, including a flexible intumescent coil product positioned for uPVC perimeter sealing. Supporting add-ons include ST99 Fire Foam, ST88 Mastic, and the STS-acoustic 422 and STS-1009 acoustic seals, with documentation issued under Warrington Fire scope-of-application certification.
The company operates a sales-led B2B go-to-market targeting doorset manufacturers, joinery firms, and carpentry businesses. It differentiates from pure component suppliers by bundling technical consultation services covering product testing set-up, design programmes, on-site joinery installation support, and regulatory compliance guidance. Pricing is not publicly disclosed; customers are directed to phone or email contact, and a wholesale account creation portal supports repeat purchasing. Distribution is direct from the single Ryton headquarters, with no disclosed subsidiaries, international operations, or third-party distribution partners.
Founded in the mid-2010s (website copyright 2016; one source dates founding to 2014), the firm employs between 11 and 50 people and shows no disclosed funding, M&A activity, or institutional ownership. Its strategic posture appears focused on deepening its UK compliance-driven niche through incremental product line extensions rather than geographic or vertical diversification.
