insulated conservatories
Turn your conservatory into a room you can use all year round
If your conservatory is freezing in winter, sweltering in summer, or just not as comfortable as it should be, an insulated conservatory could be the answer.
Tired of a conservatory you can’t use?
Most older conservatories were built with poor insulation – thin polycarbonate roofs, basic glazing and draughty frames. That means extremes of temperature, noise, condensation and high heating costs. Sound familiar?
We help homeowners fix these problems with simple, effective upgrades that include a solid insulated roof, improved glazing and energy-efficient doors. If you’re considering a replacement conservatory, this is a smart and cost-effective alternative to starting again.
- Year-round comfort
Fully insulated to reduce heat loss and eliminate temperature extremes - Better energy efficiency
Lower heating bills and a cosier space in winter - Quieter, calmer rooms
Solid roofs help block noise from wind and rain - Stylish transformation
With options that give your space a true room-like feel

I have had a excellent experience with house of glass, the sales experience was easy and pressure free, office staff very friendly, surveyor and fitters excellent and they turned it around very quickly from point of sale to install. I never give 5 stars but there is nothing to fault. Excellent

– Replacement conservatory roof (ME8)

– Replacement of roof lantern/pod (ME2)
Incredibly happy with the work, my new sky pod really lightens the space and some nice touches were added, such as capping brick pillars. From sales and office staff to the guys who carried out the work, at every stage everyone was friendly and professional.
– Upgrade of lean-to conservatory (TN2)
What makes an insulated conservatory different?
An insulated conservatory is designed to offer year-round comfort by dramatically improving thermal performance. We use modern, energy efficient materials to upgrade every part of the structure – including a solid, insulated Supalite roof, high-performance double or triple glazing, warm edge spacer bars, Low E coatings, and draught-free doors and windows. You can also add internal pelmets or insulated wall panels to enhance warmth and soundproofing even further.
These components work together to reduce heat loss, eliminate cold spots and create a more consistent, comfortable temperature throughout the year. It’s the ideal solution if you want your conservatory to feel like a real room – not just an occasional space.
The Supalite solid roof system
We use Supalite’s tried and tested solid conservatory roof system for our insulation upgrades. It’s lightweight, fully ventilated, and building control compliant – with high levels of thermal insulation built in.
Whether you’re creating a cosy insulated conservatory or looking to add value with a more modern conservatory finish, Supalite offers the ideal balance of performance and style.
If your conservatory is underused, uncomfortable or in need of repair, this upgrade could be the key to enjoying it again.
Key features include:
- Lightweight aluminium frame
- Tiled or slate-effect finishes
- Optional vents, pelmets and plastered ceilings
- High-performance insulation
Custom options to suit your conservatory
Whether you’re replacing an old one, upgrading tired windows or starting from scratch, we’ll design an insulated conservatory package to suit your home, your style and your budget.
Styles
We can install a new insulated conservatory roof on almost any style, including Lean To, Edwardian, Victorian, Gable, or completely bespoke designs.
Colours & Finishes
On the outside, you can choose from Supalite’s lightweight tile or slate-effect finishes, available in popular colours like Charcoal, Ember and Pewter – giving you a look that blends beautifully with the rest of your property.
Interior features
Inside, we’ll help you create a space that feels like a real room. Options include smooth plastered vaulted ceilings, integrated spotlights or pendant lighting, roof windows for extra natural light, and insulated internal pelmets for a seamless, cosy finish.
Windows & Doors
If your existing windows or doors are tired or inefficient, we can also upgrade these as part of the same project. Whether it’s replacing old double glazing, adding a fresh set of french doors, or opening up the space with bifold doors, we’ll help you choose the right styles and finishes to complement your new conservatory roof and enhance the whole space. Everything is made to measure and fitted by our in-house team for a perfect result.
We work with all conservatory layouts including Lean To, Edwardian, Victorian, Gable and shaped or bespoke designs.
You can also combine your insulation upgrade with new french doors, bifold doors, or replacement double glazing, all made to measure and fitted by our in-house team. It’s the complete solution for creating a conservatory you’ll actually want to use – every day, every season.
