Surface treatments


• To ensure a smooth surface and a long lifetime of the window every element of it is treated with a preservative against fungi and bacteria before varnishing it with water-based coating according to the tone chart or by the RAL card.

• To ensure the stability of the coating during use, we start with the wooden parts being treated with insecticide-fungicide agent for the prevention of attacks from fungi and bacteria.
This is followed by ground coating and application of the final layer.

• We offer a wide variety of colors, ie. systems of transparent coating with which the structure of the wood remains visible, or opaque coating according to the RAL card achieving complete pigmentation of the coating and overlay textures of wooden parts.
