Questions from Bridport
Is a pyramid lantern more expensive than a rectangular one?
Per square metre it can cost slightly more, because every pane is a triangle and the apex needs a special joint. The difference is usually small next to the effect of size and glass choice.
Can I have an opening vent in a pyramid lantern?
Some ranges can fit a vent in one of the triangular panes, others cannot. We will tell you on the quote whether your chosen range allows it.
Do I need planning permission for a roof lantern in Bridport?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
Is it worth having solar-control glass in Bridport?
With the midsummer sun about 62.7° high at noon, roof glass in Bridport gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
