Conservatory Installer FAQs

Why have an aluminium conservatory?

There are several reasons why an aluminium conservatory installation is a great way to expand your home.

Firstly, it’s strong and durable. This means that as well as providing you with a conservatory that’s more secure, this frame material will also last longer and cope with harsher weathering that wooden or uPVC conservatories.

Aluminium also offers more design possibilities. It can be bent into custom shapes, making it ideal if you want to create a unique, stylish home extension. It comes in a wide range of colours, so you can coordinate it with your existing property.

An aluminium conservatory installation can also help you maximise light in your home. They have very thin frames compared to wood and uPVC, so they’re a great choice if you want to let in as much daylight as possible.

do you need building regs for a conservatory?

Do You Need A Building Reg For A Conservatory?

If you’re planning to build a conservatory in your home, it’s only logical to consider whether or not you require a building reg for such a structure. Generally, several conservatories, summer buildings, sheds as well as outbuildings do not require building regulation approval to erect. One of the applicable rules is the fact that if they’re ( small or less than 30m2) or constructed with non combustible material, or are differentiated from structures nearby or land and don’t feature sleeping accommodation or room, then they’re not required to submit a building regulations approval application. However, it’s strongly recommended to check with your local authority before you commence the project as only they can provide the most accurate information.

Generally, conservatories should be primarily built of translucent walls and roofs, while also possessing an external type door separating them from the main building within a property. What’s more? The foundations and floors, however, can be laid in a number of ways, but you’ll have to put into consideration the conditions of the ground, trees as well as the existing drains. It’s also a wise decision to include insulation which makes the structure a lot easier to heat especially during the cold months.

Overall, conservatories are usually exempt from building regulations if the following conditions are met:

✓ If the conservatory is erected at ground level and are not up to 30 square metres in floor area.

✓ If the structure is separated from the rest of the house with an external quality walls, windows or doors

✓ If the conservatory features an independent heating system with different temperature as well as on/off controls

✓ If the glazing and electrical installations are in total compliancewith the relevant regulatory requirements.

How to build a wooden lean-to conservatory?

Lean-to conservatories are often known as Mediterranean conservatories or sunrooms and are a great way to add more living space when you’ve only got a small amount of room to work with. They usually have clean lines, a rectangular shape and attach to the side or rear of your home, which makes them one of the easiest conservatory types to build yourself.

So how do you build a wooden lean-to conservatory? The first step is to decide what you want it to look like. Most lean-to conservatories are constructed of glass and the wood frame, but you can choose to have dwarf walls too. Dwarf walls are low brick walls that are useful if you’re planning to plumb in radiators, have air conditioning installed or put plug sockets in the conservatory.

When you’ve decided what your wooden lean-to conservatory is going to look like, you’ll need to get the materials. You’ll need to choose a hardy wood – oak is the most expensive but also the most durable – and source glass for the windows. You’ll also need to decide on a roof material and work out the correct pitch.

The first step to building your wooden lean-to conservatory is to dig the foundations. You’ll then need to level the earth, then add concrete to the correct height, which should be lower than your property’s existing damp course. Then, you’ll build up to the damp course, which will be your conservatory’s floor level. Don’t forget to make sure it’s even.

If you’re building a dwarf wall, start it from the base and build up to no more than 1 metre high. Once the cement is dry, place external sills on top of the dwarf wall. You’ll then need to secure the frames; start with the one that secures to your property, then do the same for the rest, connecting outwards until they meet from the two sides. Then put up your doors.

Now it’s time to build the roof. This should be simple if you’ve bought your own custom-made kit. Place the roof ridge on top of the frames, then add the roof rafters between the roof ridge and hip bars. Fit your glazing sheets and guttering – it’s important that your wooden conservatory roof has guttering just like your house, otherwise your conservatory roof won’t last very long and could even cause rainwater to rot your wooden frames.

Once you’ve built your wooden lean-to conservatory, all that’s left is to decide on how you want to decorate it. But if this all sounds like too much, get in touch with specialist wooden conservatory installers who will be able to give you a quote for building you a lean-to conservatory.

what is an orangery?

Getting its name from it’s original use and commonly mistaken for conservatories, orangeries were developed about four hundred years ago to help protect citrus fruits from the winter frosts. An orangery is basically a room extension featuring a flat perimeter roof, brick base as well as a central roof lantern including doors and windows. Even though it originates from Italy and made more modern by Holland’s architectural development, orangeries have grown to become an ubiquitous phenomenon within the British society with thousands of the extension being built every year. They’re built in a similar way to conservatories, however, orangeries are typically developed from a brick base and usually making use of a stone or brick pillars to provide support to a flat roof perimeter. Also, the common choice for an orangery is a central roof lantern including glass panels or vent windows. Unlike conservatories which usually make use of patio doors, orangeries are more likely to have more complex bi-folding door system - enhancing the visual appeal of the extension in a more unique and stylish way.

Orangeries typically incorporates less glass when compared to a conservatory - thereby, allowing a moderate amount of natural light into the space. This way, you would not have to go outdoors to enjoy the sunlight during the summer months. Generally, the extension also offers a atrium-style ceiling height while also protecting your space from excessive sunlight and adding character to your home.

In conclusion, orangeries are an excellent choice when it comes to extending your home - be it to make a room larger or adding a new room all together. Ultimately, they go a long way to add incredible value to your home for resale purposes. Orangeries are best installed by seasoned professionals in order to ensure the best outcome.

Some of the factors that can go a long way to determine the longevity of your UPVC conservation includes the type of roofing materials used, how well it’s being maintained, the location or placement of the structure, replacement of individual conservatory parts, as well as insulation.

The type of roofing material for a UPVC conservation can either be glass, polycarbonate or tiles.

Conservatories happen to be a very popular structure in the UK as home and property owners are able to subject it to wide variety of uses such for relaxation, entertainment, hangouts with family and friends, reading and lots more. Therefore, when the conservatory roof is leaking a lot of activities could be affected. Hence, the more reason why you should know hoe to repair this kind of issue by yourself. However, if you’re not confident enough to carry out this task, we’ll recommend you call in a professional who can guarantee the best output the first time. In this guide, we’re going to look at the conservatory roof leak repair process.

  • Spot the leak. The first line of action is to examine the conservatory’s roof to identify the leaking part (tip - most leaks takes place around transparent roof panes edges). If you have a slanted roof, you’d have to look carefully. The spot where it drips may not necessary imply that its the leaking spot.
  • Remove the old seal. Climb a ladder to access the leaking pane. Then, with the help of a utility knife, lift out the panel and clean all traces of the old sealant. Once done, simply lay down a bead of the new sealant in the frame, press the clear panel back in place and apply sealant to the outer edges.
  • Cracked pane. If the existing pane is cracked or broken, simply hold the pieces tightly together by applying tape across the pane in various directions
  • Leak sealing. Another option to fix leaks is by applying a sealant around the leaking pane without having to remove it.

 

Are wooden conservatories expensive?

If you’ve ever looked into different types of conservatories, you’ll see that wooden conservatories are not the cheapest. However, that’s not a reason to dismiss them as an option for your home.

Wooden conservatories can cost anywhere between £15,000 to £60,000. While this may seem expensive, they are often a much classier option for your home and are ideal for period homes and those in a conservation area where uPVC might not be permitted.

If you choose a hardwood conservatory, you could see your conservatory last over 15 years. Most uPVC conservatories will only last around this time, and as they get old they can look shabby; it’s common for the frames to discolour in the sun. With good maintenance, wooden conservatories can look fabulous for years. Wood naturally retains heat too, so ensure that you use low-e internal glass which reflects heat back into the room and you’ll have as warm a conservatory as any.

When you weigh up all of the pros and cons of uPVC conservatories compared with wooden ones, you might come to the conclusion that wooden conservatories aren’t that expensive when it boils down to it. Although the initial cost is higher, you’ll get a better-looking conservatory that works with both modern and period properties and will look elegant and tasteful for years to come.

what is a conservatory?

What Is A Conservatory?

A conservatory is basically a structure constructed on a property that’s usually attached to the side of a home. It’s a room as well as a greenhouse that’s constructed with the help of a wide range of materials which includes bricks, wood, glass and polycarbonate. A conservatory is typically built with a great amount of glass which enables it to offer huge amount of sun and light. During construction, the idea is always to muster sufficient sunlight for the plants while also enabling a cosy room within the structure especially during the cold months. Generally, conservatory extensions’ walls are made of over 50 percent of glass, while their roofs are usually made up of more than 75 percent glass.

Thanks to the advancement in technology, conservatories have also greatly developed over the years. They’ve significantly evolved from the usual luxury greenhouses to normal and everyday home extensions. Conservatories have also grown to become very energy-efficient while also providing super comfort to the extent that they’re now being used throughout the year. And while it’s formerly known to be an occasional room, it’s now more of a home’s extension.

Legally, conservatories are usually covered by what’s called the permitted development rights which exempts them from both planning permission and building regulations. The conditions below form the legal definition of a conservatory to differentiate it from an extension.

✓ Below 30 square metres in size

✓ Constructed at ground level

✓ Separated from the main building by external walls, doors or windows.

✓ Possesses its own stand alone heating system

✓ The glazing as well as fixed electrical fittings are in compliance with the relevant building regulations.
