The spacing between ladders is slightly less than for timber blinds to allow extra support ladders to be fitted. As PVC becomes less rigid when very warm, this helps keep the slats straight in these conditions.
It is not recommended to install dark colour PVC blinds in windows exposed to the hottest sun in summer. Extreme heat inside the glass will cause distortion of slats and may damage these blinds.
