Conservatory Installer FAQs

What finish is best on a wooden conservatory?

When people talk about finishes on a wooden conservatory, there are a few different things that they may be referring to. Some may be referring to the colour and type of wood used to build the conservatory, but they may also be talking about the type of treatment used to protect the wood from the weather. We’ll cover both bases for what finish is best on a wooden conservatory here.

When you’re thinking about the best wood type and finish for the conservatory, it’s best to go with a hardwood. There are both hardwoods and softwoods, and hardwoods are the most durable. Oak is the most expensive choice but is also the most durable, so lots of people decide to go for this option. Other good choices that are slightly cheaper are Brazilian cedar and idigbo. Softwoods like European redwood or Siberian larch are cheaper still, but they won’t last as long, so it may work out more cost-effective to spend more on a hardwood.

Wood is a natural material, so it’s important to look after your wooden conservatory to prevent it from rotting or getting attacked by bugs and pests. Your conservatory will be exposed to all weathers, so you’ll need to use a good finish to ensure that it stays in tip-top condition for years to come. Your installer should be able to tell you what’s best, but some of the best finishes for a wooden conservatory include breathable varnishes and decking oil. However, if you do use an oil, it’s best to use a preservative treatment too; oil will only repel water. Joints are particularly susceptible to water penetration, so make sure you use a good wood treatment and focus on areas where water would pool during rain. Then you can apply a decking oil afterwards.

can you use an orangery all year round?

Orangeries are being built by thousands in the country year in year out and for good reasons. Not only do they provide a cost effective alternative to moving home and boosting your property’s value, but can also be used all year round. If you’re looking for a room for all seasons, then you simply would not want to overlook building an orangery. They can be quite cosy in the winter months protecting you from the wind and rain, and keeping you warm, while you can throw the doors and windows to enjoy the sunshine during the summer months.

Orangeries can be used all year long as they’re made mostly of components which makes them stay warm all through the year, which is unlike conservatories that’s almost wholly made of glass meaning they are not suitable to be used during the colder months. This implies that orangeries can be used for almost any purpose throughout the year regardless of the time of year it is. What’s more? With a plethora of style and options of orangeries you can choose from, there’s hardly any space you can’t fit an orangery, be it small or large. In recent times, more and more homeowners are now using their orangeries for a variety of purposes such as game rooms, chill out area, lounges as well as dining rooms. They have this special ability to create a seamless transition from your home to your garden while also allowing you to alter the room’s layout all year round depending on your needs at the time.

do you need foundations for a lean to conservatory?

The short and simple answer to this question is yes, just like other new extensions, you must have a foundation done for your lean to conservatory. In order to transfer the building’s weight to the floor safely, there’s a need to construct a foundation. Without it, the structural integrity of the extension would be heavily compromised. What’s more? While there’s no minimum depth requirement for a lean to conservatory, there are multiple factors that can affect the depth as well as type of the foundation. Let’s take a look!

 

  • The nearby trees. What trees do is to absorb water from the soil which can affect the foundation significantly. When water is absorbed from the soil, the soil shrinks which affects the foundation’s strength. The size as well as type of the tree will determine the extent of the water absorption from the ground.
  • The soil’s suitability. The weight that each soil can withstand varies and even more so, when environmental factors have more effect on certain types of soils than others. For instance, chalk is able to drain water away relatively easily which means that nearby trees will only have a little effect on its quality. Clay, on the other hand, shrinks when drying and also retains a lot of water. This means that nearby trees will have huge impact on clay soil which will compromise the structural integrity of the lean to conservatory. Therefore, since changes to clay mostly occur to about 0.75m depth, foundations on the soil should be constructed deeper to compensate.
  • Undisturbed ground. Before the foundations are laid, there’s a need to identify grounds that hasn’t been built on and this usually takes a depth of about 1m (this figure may vary especially in regions where drains have been laid).
how much is a conservatory?

How Much Is A Conservatory?

If you’re looking to install a conservatory in your home or property, one of the first things you’d have to consider is the cost of getting it done so you can set a budget and start planning. In this article, we’ll give you an idea of how much a conservatory price is, so you can have a rough estimate for your unique conservatory requirements.

Generally, the average cost of conservatory can be within the range of £5000 to £20000 and of course this depends on both the design and home. There are a number of influencing factors that can play a key role when it comes to determining how much you’ll be paying for your conservatory. Some of these factors include the size, style, material, colour as well as the roof type. All of these factors can greatly determine the overall price of your conservatory, so you’d most likely have to approach the acquisition process as a multi-staged concept so as to get the perfect fit for your home in every level.

So with these factors in mind, a lean to conservatory style with a polycarbonate roof material will range between £8100 to £11900. A Victorian conservatory with a polycarbonate roof material will range between £9600 to £14200. While their Edwardian and Gable counterparts will also cost within a range of £9600 to £14200 for either style.

A lean to conservatory style with a glass roof material will range between £9000 to £13200. A Victorian conservatory with a polycarbonate roof material will range between £11000 to £16200. While their Edwardian and Gable counterparts will also cost within a range of £11000 to £16200 for either style.

How can I get privacy in my conservatory from prying neighbours?

Whilst you may think conservatories are nearly all made from glass, this doesn’t have to be the case. If you live in a built-up area you could have a tiled rooftop to enable extra privacy, use obscure glass and even invest in blinds.Be aware that solid walls are possible but if the conservatory is manufactured with less than 50% of glass, you’ll need Buildings Regulations approval.

Is the wood for a DIY conservatory expensive?

If you are considering building a wooden conservatory in your home, it’s normal to be curious about whether or not the home improvement effort is costly. Basically, wooden conservatories are ones that have been constructed using a wooden structure. There are options to choose from which timber and this can also play a part in the amount you’ll have to pay. Conservatories using hardwood, which are more durable and requires less preparation, are also considerably costlier than the softwood counterpart.

For just the timber in a kit build your own conservatory you would be looking at around £10,000 to £20,000. Generally, a wooden conservatory built for you will cost you a range between £20,000 to £50,000 based on the type of wood, the size as well as the style you opt for.

In addition, wooden conservatory prices are also determined by the supplier you’re dealing with. As a result, it’s advisable to conduct a proper and detailed market research about the available suppliers and identify the one who truly offers quality materials at an affordable rate. If you wish to go for an Oak frame, the price will typically be higher.

To give your house a more traditional look, you can go for a timber conservatory rather than a uPVC one. However, it requires more maintenance than the uPVC as well as regular weatherproofing to prevent it from warping or rotting as a result of changes in humidity or temperature. If you want the timber look there are options with modern uPVC which can give a similar style but at a lower cost.

How to insulate a conservatory roof?

If you’re worried about your conservatory being too hot in the summer and too cold in the winter, you can insulate it. Older conservatory roofs are made from inefficient polycarbonate, which means that up to 25% of all the heat lost in a conservatory escapes from the roof.

To insulate your conservatory roof, you can install blinds or curtains – but they can go mouldy from condensation. There are two other options that are more long-term that could be better: upgrading the polycarbonate in the roof or opting for a solid conservatory roof.

You can add a thicker polycarbonate roof panel with better thermal efficiency if the glazing bars on your conservatory will expand to fit. This will offer better insulation, but may not last very long – maybe less than 10 years.

A solid conservatory roof is a new way of making your conservatory usable all year round. Most existing conservatory frames will be able to support a lightweight metal structure and slate-like tiles to match your home’s roof. Or you can opt for a hybrid option where the solid and glass parts are merged together. This will insulate your conservatory roof so it never gets too hot or too cold.

How long do conservatories last?

This varies according to the quality of the conservatory and installation work. If these are both high quality, your conservatory should last at least 25 years. But obviously if you notice deterioration or leaks, then this could be an early warning sign that time is running out.
