Howells Patent Glazing has confirmed that its Ultraline flat rooflight and double-hipped rooflight have successfully retained PAS 24:2022 certification, reinforcing their compliance with one of the UK’s most demanding enhanced security standards.

The certification, awarded by UL Solutions, provides reassurance to specifiers, contractors and installers that the products deliver proven resistance against forced entry. PAS 24 remains the most widely adopted benchmark for demonstrating compliance with Approved Document Q, while also forming a key requirement within the Secured by Design initiative, both central to modern building security expectations across residential construction.

PAS 24 certification is achieved through a series of stringent independent tests designed to simulate real-world conditions. These assessments evaluate not only resistance to manual attack but also mechanical loading and impact performance. In addition to security, the rooflights are tested for weathertightness in accordance with BS 6375-1:2009, ensuring long-term reliability in challenging environmental conditions.

According to Gary Howells, Sales Director at Howells Patent Glazing, retaining the certification brings a clear commercial and technical advantage to customers. He highlighted that the company’s more than 50 years of experience in aluminium overhead glazing continues to support architects and contractors seeking compliant, reliable solutions for both new-build and refurbishment projects.

Both certified systems have become popular choices within residential developments. Demand for the double-hipped rooflight has grown steadily over the last decade as homeowners prioritise open-plan extensions and brighter living spaces. The aluminium system is designed to deliver high levels of natural daylight and is supplied directly to trade professionals.

The Ultraline flat rooflight, meanwhile, is engineered to maximise glazing area while maintaining minimal sightlines. Glass rafters reinforce joints without interrupting visual continuity, giving architects flexibility when specifying larger expanses of glass. Typically sized at around 2.4 metres by 1.2 metres, the system suits three- to four-metre house extensions where discreet, low-pitch roof glazing is required.
