Howells Patent Glazing has announced that its Ultraline flat rooflight and double-hipped rooflight have successfully retained PAS 24:2022 certification.
Awarded by UL Solutions, this accreditation assures specifiers, contractors and installers that these rooflights deliver proven resistance against forced entry and can withstand an opportunistic burglar, meeting the highest security requirements under current building regulations. PAS 24 is the most commonly used standard to demonstrate compliance with Approved Document Q and is also a core requirement of Secured by Design.
Performance is proven through a series of independent tests. Products are evaluated for both security and weathertightness (BS 6375-1:2009). Methods include a manual attack, mechanical loading and impact tests.

Gary Howells, sales director for Howells Patent Glazing, said: “PAS 24 gives us a clear commercial advantage and we are pleased to extend this to our customers. With more than 50 years’ industry experience, we are considered one of the country’s leading manufacturers of aluminium overhead glazing solutions. Customers and specifiers know that our products are fit-for-purpose and trust that they will help deliver compliant, high-quality new build and refurbishment projects.”
According to Howells, the two certified rooflights are proven favourites for residential projects.
Designed to maximise daylight, Ultraline, meanwhile, gives architects and specifiers the freedom to specify larger expanses of glass. Glass rafters (fins) reinforce each joint without breaking the sightlines. The low-pitch aluminium rooflight is discreet, typically measuring 2.4m x 1.2m.
Installers also benefit from a preassembly service. Rooflights under 5m x 2m can be delivered unglazed and preassembled direct to site in an unmarked vehicle; larger units are supplied in sections. With early morning drop-offs, Howells says that Ultraline can be installed in a single day.
Howells also offers a national supply only and supply and fit service which includes site surveys, full drawings and installation.
