FAQ

Choose a category
Can it be partway open with a key switch for ventilation and control, with battery backup?

Yes, this is possible with a 24vDC system. You would need a 5A panel and a retractive switch, and then adjust the settings in the control panel.

Do you supply access hatches for ceiling space without roof access?

No, Sertus doesn’t currently supply this.

Can it be supplied with self-cleaning glass?

We don’t supply self-cleaning glass at the moment.

Can I install a ladder on your Roof Access Hatch models?

Yes, we can supply ladders for our RAH-R and RAH-C models. However, please note that installing a ladder will reduce the free vent area by approximately 0.4m².
