Questions from Welwyn Garden City
Is self-cleaning glass the same as solar-control glass?
No. Self-cleaning is a coating that sheds dirt; solar control reduces heat gain. Many lantern units combine both.
Can the coating be damaged?
Yes, by abrasive cleaning, some chemicals and silicone. Follow the care instructions supplied with your lantern.
Is it worth having solar-control glass in Welwyn Garden City?
With the midsummer sun about 61.6° high at noon, roof glass in Welwyn Garden City gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
