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.
