Glazing Vision has supplied Flushglaze walk-on rooflights to a bayside house extension in San Francisco
Glazing Vision’s Flushglaze rooflight is designed to withstand heavy foot traffic while remaining weathertight
Flushglaze walk-on rooflights from Glazing Vision have been specified by ODS Architecture for a multi-level roof terrace that forms part of an extension to a period bayside house in San Francisco, USA. Planning constraints restricting the placement of new windows necessitated the use of rooflights to illuminate the bedrooms and bathrooms located below the roof deck.
The rooflights on the main deck feature a highly slip-resistant sandblasted glass finish
Imported from the UK, Glazing Vision’s Flushglaze rooflights were specified for several reasons. First, they could be installed flush with the terrace floor. Second, they have a frameless aesthetic. Third, they can withstand heavy foot traffic while remaining weathertight. Last but not least, they can incorporate different surface finishes, ensuring privacy for the rooms below.
The main deck features three rooflights, each with a sandblasted glass finish. The latter not only ensures privacy and diffused daylighting, but also provides improved slip-resistance. Glazing Vision’s sandblasted glass achieves a pendulum test value (PTV) of 50 as standard – well above the low-slip potential risk threshold PTV of 36+.
A frameless aesthetic maximises daylight transmittance and visual eleganceÂ
The ‘crow’s nest’ viewing platform at the top of the house is fitted with a single, 1700x800mm Flushglaze rooflight incorporating a fritted finish. Covering 40 per cent of the glass, the screen-printed frit pattern provides high levels of slip-resistance (up to a PTV of 60), while ensuring excellent daylight transmittance. To find out more about design considerations for roof terraces, request a CPD.
