Nova General Technical Information
The Nova Spiral Staircase kit can be installed with a clockwise or anti-clockwise rotation. You decide when you fit the staircase! The choice of three diameters - 1200mm, 1400mm and 1600mm, should suit almost any project.
Please note that the ceiling opening size should ideally be 100mm (4") larger than the diameter of the staircase to ensure that you can use the handrail safely as you travel up the staircase.
The standard kit has 13 risers (12 treads + 1 landing tread) and the tread rise is adjustable from 210mm to 233mm, although UK regulations have a maximum tread rise of 220mm. This means that the standard kit will suit floor to floor heights of up to 3035mm (or 2860mm to comply with UK Building Regulations). If your floor to floor height is higher than this, you simply need to add additional tread kits as required. See the Accessories page for more information.
The individual tread rise is adjusted by adding ingenious shims between each tread to provide your overall correct staircase height. These are supplied in the kit, together with all fixings and fittings required plus clear installation instructions and an installation DVD!
The gap between the vertical spindles on the balustrading of the Nova spiral stair is less than 100mm to satisfy the Building Regulations' 100mm gap rule. Matching powder coated steel riserbars are available as an accessory kit to fit between the open treads to satisfy this same requirement. See the Accessories Pages.
