Domestic and Commercial Glazing Manufacturer, Supplier and Installer


Howells Patent Glazing is pleased to announce the launch of its new glass rafter rooflight, Ultraline which was unveiled at FIT Show 2019.  Designed to maximise daylight, Ultraline allows for larger expanses of glass.  Each joint is supported by a glass rafter, or fin, which reinforces the structure without breaking the sightline.


The low-pitch aluminium rooflight is non-intrusive and typically measures 2.4 metres long and 1.2 metres wide, ideal for the average house extension, at around three to four metres.  However, as each rooflight is designed and made to order, customers can increase the width and depth to suit the application.  Loadings are calculated by an independent glass consultant.

Installers will benefit from the company’s preassembly service.  If the rooflight measures less than five metres by two metres, the unglazed rooflight frame can be delivered preassembled, direct to site in an unmarked vehicle.  If the rooflight exceeds these dimensions it can be delivered in multiple parts.  Early morning drop-offs mean that the Ultraline roof light can be installed in just one day.


With manual handling limited to 130kg, larger expanses of glass will require a crane and glazing robot for installation.


Preassembly offers greater peace of mind as the corners are factory sealed.  Ultraline has been independently tested for Weathertightness (BS 6375 Part 1) and Resistance to snow and permanent load (EN 14351).  For a compliant installation, fitters should refer to the manufacturer’s installation guide.


Howells offers several glazing options with clear toughened glass as standard.  Customers can upgrade to solar-controlled, high performance or super neutral glass.  For certain applications such as swimming pools, schools and hospitals, the company offers a toughened laminated glass.


It is certified against PAS 24 and Approved Document Q (Security – Dwellings), offering peace of mind against low-level burglary.  The glass rafter rooflight also meets the requirements of Secured by Design.


For added impact, Ultraline can be powder coated in a standard RAL colour, including dual colours (one colour inside, another out).  Typically, Howells offers High Gloss Black or RAL 7016M Anthracite Grey externally and  RAL 9910S Hipca White internally, as standard.
