Why conservatory roof insulation?

Conservatory Roof Insulation

Your most frequent questions, answered.

What is conservatory roof insulation?

Conservatory roof insulation involves enhancing your conservatory with a layer of specialised insulation that is installed directly beneath the existing roof structure. This modification is designed to regulate temperature, reduce noise, and increase the usability of the space throughout the year, irrespective of weather conditions. The process helps to transform a conservatory from a seasonal room to a comfortable, year-round living space.

How does conservatory roof insulation work?

Conservatory roof insulation works by applying a high-performance, multi-layered insulation material beneath the interior surface of the conservatory roof. This layer acts as a barrier to heat transfer, effectively keeping heat out during the summer and retaining warmth during the winter. This layer of high-performance insulation is then finished with either fresh white PVC panels or plaster.

Do you need planning permission to insulate your conservatory roof?

Generally, insulating your conservatory roof does not require planning permission as it is considered a permissible development. However, if your home is listed or located in a conservation area, you may need to consult your local planning authority to ensure compliance with specific regulations. Our friendly team can advise. 

Why do homeowners look to insulate their conservatories?

Homeowners choose to insulate their conservatories to improve comfort, enhance energy efficiency, and increase the usage of the space throughout the year. Insulation helps to maintain a consistent temperature, mitigating the extreme hot and cold conditions typically experienced in conservatories, transforming them into practical, everyday living areas. Fancy a new home office, dedicated gym space, or a snug with a view? Then conservatory roof insulation can make that happen! 

Is conservatory roof insulation cheaper than the alternatives?

Conservatory roof insulation is more cost-effective compared to alternatives like a complete roof replacement, the installation of new double-glazing, or a brand new conservatory! It provides a budget-friendly solution with substantial benefits, such as improved thermal performance and reduced energy costs, without the need for extensive structural changes.

What do homeowners who have insulated their conservatory roofs say?

Over 700 happy homeowners on Trustpilot report significant improvements in the comfort and usability of their space after insulating their conservatory roofs. Many reviews highlight the reduction in temperature fluctuations and the ability to enjoy the conservatory all year round. Satisfied customers also note the reduction in external noise and the overall enhancement in the living quality within their conservatories.

How long does conservatory roof insulation last?

Conservatory roof insulation is designed to be long-lasting, with the Sagars365 system guaranteed for 10 years with a lifespan well beyond this. Proper maintenance can also extend the longevity of the insulation, ensuring it remains effective for many years.

Will conservatory roof insulation save me money on my energy bills?

Yes, by improving the thermal efficiency of your conservatory, roof insulation can help reduce the need for additional heating or cooling, which in turn can lead to significant savings on energy bills. Our customers report they save an average of 25% on their heating bills after conservatory roof insulation has been installed!

How long does it take to insulate my conservatory roof?

The conservatory roof insulation process typically takes about one day, although this can vary depending on the size and specific design of the conservatory. The installation is designed to be minimally invasive, allowing most homeowners to enjoy their newly insulated conservatory without significant disruption to their daily lives. 

Can I choose my insulated conservatory roof finish?

Yes! You can choose what finish you would like, including new PVC panels of fresh plaster for that new-build-extension feel. We can also install new or maintain existing light fixtures, work around ceiling fans, and include skylight gaps to allow more light though.

How can I start my conservatory transformation?

Simple! Just download our brochure and request a quote. One of our friendly, family team will reach out to discuss your conservatory and, if you’re happy, arrange a free appraisal and quotation. And with flexible interest-free finance available, there’s no need to delay!
