The specialist testing conducted on the effectiveness of protection against the heat gain, showed that the main factor that has a direct impact on well-being of humans is temperature, hence the optimal selection of accessories, both external and internal, is so important.
The graph shows the temperatures in enclosed spaces, depending on the type of screens used in the roof window accessories.

 The graph presented above shows that the external accessories for windows protect against heating of the room more effectively than the accessories installed inside. It is easy to notice that AVR roller shutter offers the most effective protection against excessive heat gain. In addition, it darkens the room to a large extent and provides privacy.

Internal accessories play a limited role in the effective protection against the heat and their main task is to regulate the light getting into the room, provide decoration and a sense of privacy. All these requirements are satisfied by AVF roller shutters.

To meet the guidelines of DIN 5034-1 stating, inter alia, that the rooms in summer should be protected as far as possible by means of external screening devices, mounted before the glass and reflecting the heat, Kronmat Sp. z o.o., in addition to accessories for Velux roof windows, offers also a product for vertical windows - VMZ Blockheat fabric awning blind.
