Howells launches new glass rafter rooflight 

Housing Thu, Jul 4, 2019 7:44 AM

Howells Patent Glazing is pleased to announce the launch of its new glass rafter roof light, Ultraline.

Designed to maximise daylight, Ultraline offers architects and specifiers the freedom to use 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 roof light is non-intrusive and typically measures 2.4 metres long and 1.2 metres wide. However, as each roof light is designed and made to order, specifiers can increase the width and depth to suit the application. Loadings are calculated by an independent glass consultant.

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.

Ultraline has been independently tested for Weather tightness (BS 6375 Part 1) and Resistance to snow and permanent load (EN 14351). It is certified to PAS 24 and Approved Document Q (Security – Dwellings), offering peace of mind against low-level burglary. The glass rafter roof light also meets the requirements of Secured by Design.

Howells’ aluminium roof lights are thermally broken for superior thermal performance, Ultraline achieves an overall U-value of just 1.4 W/m2K when using a 28mm double glazed unit with a centre pane value of 1.0 W/m2K. Triple glazed options also available.

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 and RAL 7016M Anthracite Grey externally and RAL 9910S Hipca White internally, as standard.

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

Each rooflight is manufactured using Howells’ bespoke rooflight system in the company’s ISO 9001:2015 certified facility.
