Double Glazing Units in Manchester
Supply and installation of sealed units across Greater Manchester.
Glazing Solutions for Manchester's Diverse Housing Stock
Greater Manchester's housing is remarkably diverse. The leafy suburbs of Didsbury, Chorlton, and Sale are characterised by Victorian and Edwardian terraces and semis with bay windows, many still fitted with their original timber frames. In these properties, replacing failed sealed units within the existing frames is the most cost-effective and least disruptive upgrade – something we do hundreds of times each year across south Manchester.
Closer to the city centre, Ancoats, the Northern Quarter, and Castlefield are home to a growing number of mill and warehouse conversions. These striking buildings often feature oversized industrial windows – some with steel Crittall-style frames – that require bespoke sealed units manufactured to non-standard dimensions. We produce units up to 3000mm – 2000mm to accommodate these larger openings, and our acoustic glass options are particularly popular for mill conversions overlooking busy roads.
Further out, areas like Bolton, Bury, Rochdale, and Oldham have a mix of stone and brick terraces, 1930s semis, and modern estates. These properties typically suit standard 4-16-4 argon-filled units with Low-E coatings – the workhorse specification that delivers reliable thermal performance at a competitive price, comfortably meeting Building Regulations Part L.
Manchester's climate – wetter and cooler than the national average – makes well-insulated glazing especially important. Upgraded sealed units reduce condensation, draughts, and heat loss, with noticeable improvements in comfort from the first winter. Use our measuring guide to get started.

What Our Manchester Customers Say
"We live in a converted mill in Ancoats with huge original steel-framed windows. Finding someone who could make sealed units to fit was a nightmare until we found Double Glazing Units. They manufactured bespoke units to the exact dimensions, including acoustic glass for the road-facing side. The difference in both warmth and noise has been transformative – our heating bills dropped noticeably that first winter."
– James & Rachel P., Ancoats, M4
Frequently Asked Questions – Manchester
Manchester's classic red brick terraced houses typically have timber or early uPVC frames with standard-sized openings. For most terraces, a 4-16-4 argon-filled sealed unit with a Low-E coating is the ideal specification – it delivers excellent thermal performance at a competitive price and comfortably meets Building Regulations Part L. If your terrace has original timber sash windows, we can manufacture slimline replacement units to fit within the existing sashes.
Yes. Mill conversions are one of our specialities in Manchester. These properties – found throughout Ancoats, the Northern Quarter, and Castlefield – often have large, industrial-style windows with steel or aluminium frames. We manufacture bespoke sealed units to fit non-standard frame profiles, including oversized panes, arched tops, and Crittall-style configurations. We also offer acoustic glass options, which are particularly popular in city centre mill conversions where noise reduction is a priority.
Standard sealed units are typically manufactured and delivered to Manchester addresses within 5–7 working days. Bespoke sizes, specialist glass types (such as acoustic or self-cleaning), and non-standard configurations may take 10–14 working days. We deliver to all Manchester postcodes and surrounding areas including Salford, Stockport, Trafford, and Bolton.
Absolutely. Manchester's higher-than-average rainfall and cooler winters make well-insulated glazing particularly important for comfort and energy efficiency. Upgrading from single glazing or failed sealed units to modern argon-filled Low-E units can reduce heat loss through windows by up to 50%, making a noticeable difference to warmth and heating bills. It also helps reduce condensation, which is common in Manchester properties during the wetter months.
