Sun shading sistem should be universal - to shade the day in the evening preceding the date of entry of light beams, the room cool in summer and in winter to save heat energy. Aesthetic aspect can not be neglected - it is one of the facade design of critical components of modern architecture.

Effective sun shading is a must for living and working areas alike. Without it, the room might heat up within a very short period of time despite existing ventilation. And this is due to the greenhouse effect which keeps the heat inside even when it is pleasently cool outside.

	Depending on the glazing, approximately 30‑80 % of the sun radiation penetrate into the room.
	External sun shading can keep the sun off to a minimum of 10‑20 %.
