Powder coated windows are produced in a controlled finish of substantially uniform appearance. When deciding on colour, appearance may vary according to light source. Where colour accuracy is vital a powder coated panel should be required to more accurately demonstrate the effect you should get.
When inspecting windows in-situ all significant surfaces of powder coated aluminium profiles shall be assessed for uniform appearance, colour, texture and gloss, and be essentially free of visible defects. For all in-situ viewing a minimum of 2 metres shall apply. Powder coated finishes are preferably matched in daylight, but not direct sunlight.
