What are the lead times for Glassworx products?

Lead times vary by brand. Internorm is typically 8–10 weeks, Dako is usually 6–8 weeks, and QFort (Cortizo) is generally 10–12 weeks. Lead times can change depending on factory workload, so for an accurate timescale it’s best to make an enquiry via our contact form.

Is triple glazing more expensive than double glazing?
