Questions from Isleworth
Is solar control the same as tinted glass?
Solar-control coatings often look slightly tinted, but the performance comes from the coating, not just the colour.
Can blinds do the same job?
Internal blinds reduce glare but the heat is already inside the room. Glass that stops the heat at the roof is more effective.
Is it worth having solar-control glass in Isleworth?
With the midsummer sun about 62.0° high at noon, roof glass in Isleworth gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Can you fit a roof lantern in Isleworth?
