LRV CONTRAST CALCULATOR

Select the required door facing and handle finish to obtain the LRV values and difference.

LIGHT REFLECTANCE VALUE (LRV)

This is a measure as a percentage of visible and useable light that is reflected from a surface when illuminated by a light source.

The scale measures from zero (absolute black, absorbing all light & heat) to 100 percent (pure white, reflecting all light).

The 2010 Equality Act requires all new and refurbished public buildings and workplaces comply with current regulations ensuring safe entry, exit and safe passage throughout the building.

The LRV should be at least 30 points between door face and the adjacent frame/wall. This standard also requires the door face and its fitted ironmongery to be at least 15 points.

Please bear in mind that this should only be used as a guide and that factors such as door veneers or hardwood timbers changing colour over several years (lighter timbers tend to get darker and lighter timbers darker) can affect the LRV. Other considerations are the LRV can change subject to the lacquer, oil, and the sheen level of the finish applied.
