Conservatory Insulation & Glazing Upgrades
Double/triple glazing plus floor and wall insulation — smaller, less disruptive jobs than a full roof replacement
Pros
- Cheaper and less disruptive than a full roof replacement, and can be phased over time as budget allows
- Modern glazing coatings cut both winter heat loss and summer solar gain
Cons
- Won’t fully fix an uninsulated roof on its own — if the roof is the main source of the problem, glazing/wall upgrades alone will only partially help
- Quality varies a lot between installers — always compare U-value/energy-rating specifics, not just headline ‘double glazed’ claims
About Conservatory Insulation & Glazing Upgrades
Short of replacing the roof entirely, several smaller upgrades can meaningfully improve comfort: upgrading old single or basic double glazing to modern high-performance double or triple glazing with better U-values and solar control coatings, adding insulated internal wall panels or proper insulation behind dwarf walls, and upgrading the floor if it was originally built as a lightweight or uninsulated slab. These jobs are typically cheaper and less disruptive than a full roof replacement, and can be phased incrementally rather than done all at once — though the ceiling or roof usually remains the single biggest source of heat loss and gain if left untouched.

Frequently asked questions
Is triple glazing worth the extra cost over double glazing for a conservatory?
It depends on orientation and use. For a north-facing conservatory used as a year-round living space, the extra insulation can be worthwhile; for a mostly-summer sunroom, standard high-performance double glazing is often adequate. A reputable installer should be able to model the difference for your specific room rather than upselling by default.
Are you a conservatory installer yourselves?
No — Compare Conservatories is an independent comparison and information service. We recommend always checking an installer’s FENSA or Certass registration directly before any glazing work begins.
Is all the pricing on this site guaranteed?
No — costs mentioned are typical UK trade-source ranges, not fixed quotes. Always get itemised quotes from more than one registered installer before committing.
What happens after I request a quote?
A partner installer reviews your details and gets in touch to arrange a proper site survey — there’s no obligation to proceed with any quote.
