Conservatory problems due to lack of insulation

Conservatories should be a place to relax, enjoy, and unwind. However, due to poor maintenance, issues might arise and turn your conservatory into a headache.

Are you fully enjoying your conservatory? Or is it time for a conservatory transformation?

More often than not, and due to poor insulation, homeowners feel the need to stay away from their conservatories during the hottest summer days and the most bone-freezing winter weeks. 

This is not the way it's supposed to be!

If you identify with any of these scenarios, it's time to consider a conservatory roof replacement to insulate it properly. Projects4Roofing is here to help. 

Conservatory problems due to lack of insulation

Conservatories lacking insulation can lead to all sorts of complications. The most common are conservatories being too hot in summer and too cold in winter. Leaks, condensation, and mould might also appear and concern homeowners. 

Let's double-click into some of these issues to understand why they occur and try to find a way to end them. 

Extreme temperature conservatories
Experiencing extreme temperatures is, by far, the most common complaint homeowners have before transforming their conservatories. The fact is, commonly, a glass or polycarbonate roof turns your conservatory into a sauna on a hot day. During winter, sitting and unwinding there is unbearable without turning on the heating up to its maximum potential.

Why does this happen?

The issue lies in the roof. Polycarbonate and glass roofs lack proper insulation. In summer, this results in hot air penetrating into your conservatory inside conservatories. In winter, quite the opposite occurs, and heat easily escapes through the uninsulated panes of glass or polycarbonate roofing.

To palliate this dilemma, these are some of the solutions homeowners try: 
  • Putting up blinds
  • Installing an air conditioner or fan
  • Using insulated roof panels
  • Installing solar control films
  • Using electric radiators
However, these alternatives are short-termed and do not tackle the root cause: lack of insulation. In addition, some of the mentioned options can even be hazardous. The excess weight of roof panels might be too heavy for the current roof structure, resulting in a conservatory that does not meet building regulations. To top this off, even if the panels are not too heavy, their poor ventilation will probably result in condensation and mould - two other common conservatory complaints. 

Condensation and mould
When homeowners first wanted to enjoy an extra room at home, a glass or polycarbonate roof was a popular choice. However, these types of roofs require high and dedicated maintenance, which is not easy to keep up with. 

When this occurs, these types of roofs become prone to leaks. Moreover, they allow cool air to enter conservatories, which should not occur. Air leakage can cause moisture problems that might harm owner's health and affect the conservatory's structure, making it less durable. It is at this point that condensation starts to manifest in conservatories. 

The unattended build-up of condensation in humid conservatories generally leads to the appearance of mould. This fungus can start growing on walls, fixtures, or roofs. 

Black mold (the most common in conservatories) can cause immune and respiratory issues, allergic reactions, and other nasty health problems. 

No homeowner wishes to suffer due to their conservatory's poor maintenance. If you feel this is your case, read on to find out how to end your agony.

Chapter 2

Rising energy prices

Is your conservatory causing your energy and heating bills to hit unprecedented costs? You are not alone!

Online searches for insulation systems and renewable energy sources have increased considerably during the past year. Unfortunately, given the global economic situation, this comes as no surprise. The cost of heating and cooling has escalated tremendously, and homeowners are seriously concerned about it. 

When it comes to conservatories, these are not the exception. Keeping conservatories warm in winter and cool in summer demands the use of radiators, fans, air conditioners (if you're lucky enough), and many other electric artifacts. All of these consume a significant amount of energy. Considering rising energy prices, this combo is becoming unbearable for many homeowners. 

This situation is leading Britons to seek alternative and more economical ways of maintaining a stable temperature in their conservatories. Fortunately, for most of them, there is an energy efficient and long-lasting solution.

Chapter 3

An all-in-one solution

If you've identified with any of the troubles mentioned in the previous sections, we might just have the solution for you: transforming your conservatory roof with a solid, insulated one.

Let us explain how having a solid roof conservatory will help you say goodbye to your conservatory headaches.

Solid, insulated conservatory roofs

A solid, insulated roof that's completely weatherproof while still allowing proper ventilation will prevent condensation from forming in your conservatory. It will also ensure that the conservatory is never too humid, thereby tackling the root cause of mould.

Also, by choosing conservatory roof insulation, you will be installing a roof with excellent thermal properties. This will allow you to enjoy your conservatory all year round without relying on expensive cooling and heating methods. Forget about an unused conservatory in winter or summer. Converting your conservatory into an insulated one will grant you the possibility of relishing your conservatory, no matter what the weather outside is like. 

Conservatory roof replacement to transform your conservatory is a win-win situation! You get more conservatory uses, less money spent on heating and cooling bills, an energy efficient home, plus added value to your property.

Building Regulations are a must

Regulations are the only way to ensure that people are living in safe, accessible, and sustainable conservatory conversions.⁣

In our previous section, we lightly mentioned building regulations, and you might wonder, “what are building regulations?" or "should I seek them when transforming my conservatory?”. Let us clear your mind of these and any other concerns you may have.

What are building regulations?

Building regulations are structural and design standards applicable to all buildings that help ensure they are constructed safely and sustainably. These regulations are developed by the UK government and approved by Parliament.

Many firms with substandard roofing systems, possibly worried that their roof won’t pass inspection, will claim that building regulations are unnecessary to replace your conservatory roof.

Avoid being scammed! Building regulations are, in fact, ALWAYS required for any conservatory roof transformation. Ensure that you receive a visit from your Local Authority Building Inspector during the installation of your insulated conservatory roof.
New Part L regulations

Building Regulation's Part L deals with energy efficiency and establishes requirements for carbon emissions and energy performance in both new and existing structures. Performance is determined by thermal transmittance, commonly referred to as U-value. A structure's U-value will be lower, and its heat transmission rate will be so, as well as a result of improved insulation.

The new Part L Regulations state that when transforming your conservatory after 16th June 2022, you must ensure the replacement roof achieves a U Value of 0.15W/m²K. This is a 16.6% thermal improvement from the old U Value of 0.18W/m²K.

The upside to Building Regulations

While Part L is a legal requirement. There are benefits to managing the U Values in your home. Let's walk you through some of them!

Investing in high-quality insulation will make your home even more energy efficient, which can help you significantly save on energy and heating bills while also improving your quality of life.

What's more, if you choose to install a Guardian Warm Roof from Projects4Roofing, you can rest assured that your conservatory roof replacement project will comply with all building regulations. As a matter of fact, unlike many of its competitors, Guardian has been working to ensure its roof meets the new standards by upgrading the thickness of insulation to 160mm on all their solid replacement conservatory roofs to achieve a U Value of 0.145W/m²K.

As a plus, if you would like to remove the doors between your conservatory and home to create an open plan living space, the improved thermal efficiency of the Guardian Warm Roof will help to maintain an ambient temperature throughout.
