The window insulators have a lifespan in excess of 15 years. Cleaning with a wet cloth.
Aesthetics: Interior decorators & designers
Because of the see through transparency of the window insulator during the day, it has no effect whatsoever on the colour scheme and interior décor of the office/room as the outside view is dominant and the colour of the window insulator becomes neutral.
In fact, colour schemes, décor & lighting in focus points of the room/office are enhanced because of glare reduction and blocking of harmful UV on fabrics and furniture.
Plus you, as interior decorator/designer, can offer the added advantage of protecting the furniture & fabrics of your client, over and above the other advantages mentioned elsewhere on this web page.
A further advantage is visibility from the outside, during sun light hours, into a room/office fitted with our window insulators, is virtually none, thus enhancing privacy without the unnecessary expense of curtains or blinds (which in any case have a reduced lifespan because of UV damage).

With a conventional roller blind (spring loaded, ratchet or electric) for windows which are occasionally opened.

(Window Insulator on roller blind mechanism in front of window only – notice glare through glass of door)
Mounted in a light metal or aluminum frame affixed to window frame leaving a space of approximately 2,5 cm – 4 cm between material and window glass.
(Only the middle window fitted with the Window Insulator* screen)
