Conservatories FAQ

In this section we attempt to answer all of your question about the design, manufacture and installation of your conservatory.

How Do Conservatories Work?

We use this section to discuss how conservatories work, how to insulate them against extremes in temperature and how we discuss how secure they are.

If we have not answered all of your questions or if you need more information, contact us today.

Will a solid roof help to insulate my conservatory making it more comfortable throughout the year?

A solid roof will definitely prevent as much heat from escaping from your conservatory, but this is not the only aspect of year round comfort, ventilation is also vital to maximum comfort in the conservatory.

What is Solaroof?

A Solaroof is an roof improvement designed to help keep the ambient temperature of the conservatory at comfortable levels. It will also help to keep the contents from sun damage.

This product will keep out up to 98% of the sun’s UV rays that fade the fabrics in the room.

It will keep the room cooler in summer as Solaroof also stops solar heat from entering the room, rejecting as much as 75% of the heat of the sun. This ensures that your conservatory is usable during the warmer months of the year.

With Solaroof there is no need to wear sunshades in your conservatory as it reduces solar glare by as much as 80%.

You’ll find all our conservatory designs available with the Solaroof finish on our conservatory page.

What is Solarguard?

Solarguard is similar to Solaroof but it is made from polycarbonate.

This roof panel is made from 25mm, 4 wall multi chambered polycarbonate sheeting. It reflects back 92% of the heat of the sun, absorbing just 8%. It also stops heat from escaping and has a U value of 1.7kwh per square metre per year.

Does FENSA cover conservatories?

All Seasons Roof are a FENSA registered company. Only conservatories that must comply with building regulations require FENSA certificates. FENSA (Fenestration Self-Assessment) ensure that targeted energy efficiencies are met and that insulation meets stipulated standards.

Will my Buildings Insurance cover my conservatory?

It is always a good idea to check with your insurer, but usually once the conservatory forms part of you home it will be covered by your insurance.

What are U-values and how do you calculate them?

U-value is a measure of the heat loss or thermal transmittance through the glass. It is measured in Kilowatt hours, per square metre per annum. The lower the U-value the more you will save in energy.

Triple glazing will have a lower U-value than double glazing since the third pane of glass creates further insulation against heat loss.

The Solar Factor is the G value. This measures the amount of solar energy allowed into the room through the window. You want the G value to be as high as possible as the higher the value the the better your home is at harvesting solar energy. The higher this value the more energy efficient your home and the less you’ll pay for energy.

The G-value is measured in Kilowatt hours per square metre per annum. Double glazed windows have a higher G value than triple glazed windows as the extra pane in triple glazing stops much of the heat from getting through the window.

The measure of air leakage through a window is known as the L-value and it too is measured in Kilowatt hours per square metre per annum. Window technology has improved to the point that some windows such as casement windows can achieve an L value of zero.

In combination these three values equal the window Energy Index, the measure of Window Energy Rating.

Are Conservatories Less Expensive Than Building Extensions?

From the outset building extensions are typically more expensive as the design and construction tends to be a lot more complex. Building extensions have in the past been a much more energy efficient solution but conservatory design has improved over the years and they can now be kept at a comfortable temperature year round without incurring major expense.

One of the big benefits of installing a conservatory is that they normally do not require Building Warrants. You can manage the amount of light that they let in by opting for a solid roof. You can also add a solid roof to your existing conservatory.

Which is Best a Conservatory, Orangery or an Extension?

The best option depends on what you want the extra space for. It will also depend on how much you have to spend and how much available space that you have in your home.

A conservatory is built with glass walls and glass or polycarbonate roof. This means that it has plenty of light and heat from the sun. It is a great way to bring your garden into your home and creates a relaxing place for leisure time. An orangery tends to be quite ornate and will contain brick columns and will have a lantern roof. If you opt for an extension you can add another room manage the light while still enjoying the views.

Orangeries and extensions are typically more expensive and All Seasons Roof can construct a tailor made conservatory will be built according to your specifications to meet all your household needs. Advanced technologies and designs has meant that conservatories are almost as energy efficient as an extension or an orangery and you can add a solid roof for further efficiencies and to make it look like just another room in the house.

What Are Conservatory Roofs Made Of?

Years ago conservatory roofs were constructed from polycarbonate sheets. They were inefficient and the rain on the roof was very noisy. Today conservatory roofs are built from from uPVC or timber and energy efficient glass.

Solaroof, a product of All Seasons Roof, insulates the roof so that the conservatory does not succumb to extremes of temperature and the tint protects your fabrics and soft furnishings from the ravages of the sun. With Solaroof you can use the conservatory year round without running up your energy costs.

You can also choose a solid roof conservatory. In this way you stop excess heat and light from entering the conservatory through the roof without losing the views or the light which enters through the glass walls. The roof has a beautiful slate look and roof windows are an additional option. The roof windows can be treated with Solaroof.

Are Conservatories Cold In The Winter?

In winter a conservatory can become too cold to enjoy unless you take measures to warm keep it warm. Underfloor heating is both cost effective and energy efficient, radiators are another option and window blinds can stop the heat from escaping through the glass.

All Seasons Roof can provide you with argon sealed glass units which are a lot more efficient than air filled units. This means that you will not use too much energy trying to heat your conservatory in winter as it loses temperature through the windows. It follows that when you lose less heat you use less energy and waste less money.

If you install a solid-roofed conservatory you will lose less energy through the roof, keeping the heat in.

Are Conservatories Secure?

A well built and installed conservatory should never be insecure and should be as difficult to access as any other point in your home. You can take additional security measure by installing toughened glass, and beading on the inside. Doors and windows can include hinges that will resist attempts to force them and advanced locks. According to the Building regulations you must have a barrier between the house and the conservatory, and you should ensure that this is equally secure.

Your conservatory should be as secure as your house. We have a large number of secure lock options that you can choose from with features that include:

  • Anti-bump, anti-pick, anti-drill, anti-plug extraction, anti-snap Yale 3-star cylinder locks
  • Multi-point locks
  • Aluminium handle back plates
  • Steel hook bolts that secure into stainless steel keeper plates in the frame
  • Strong Slimline hinges that will resist forceful entry
  • 10 year guarantee on uPVC products

Are Conservatories Livable Rooms?

Conservatories can get very warm in summer so cooling and ventilation are required. In winter radiators or underfloor heating are a must. By installing a conservatory with a solid roof you can use the room for almost any activity in your house, including kitchen extensions and lounges.

When designing your conservatory you need to take account of practical considerations including the number of electrical outlets you will need and the energy requirements for cooling and heating.

Are Conservatories Too Hot In The Summer?

A conservatory is a little like a greenhouse and they can therefore become rather warm in the warm summer months. Fortunately conservatory technology has made major advances over the years and modern conservatories do not have to be unbearably hot.

All Seasons Roof’s Solaroof banishes up to 98% of ultra-violet rays and 75% of heat of the sun from the roof. It dissipates 80% of visible glare. This helps to keep the room cool in summer. It also protects your furniture from the ravages of the sun.

All Seasons Roof conservatories are also available with the solid roof option that will keep the heat of the sun from entering the room from above and will make the room look like an integrated part of your home.

There is a wide variety of cooling options available including adequate ventilation, extractor fans and air-conditioning. Minimum ventilation requirements are laid out in the Building regulations. If you have opted for a glass roof, consider roof ventilation as it does an excellent job of keeping the place cool in the summer months. Blinds look great and can help keep the room warm in winter.

How Do Conservatories Trap Heat?

There is nothing like a conservatory on a cool and sunny day. The glass helps to trap the heat of the sun and prevents the cool wind and rain from entering, making it an excellent place to relax and enjoy the heat of the sun.

A conservatory allows heat to enter from the walls and the roof and the temperature can be better controlled when you choose a solid roof rather than the typical glass one.

Opt for Double glazed windows for better insulation and energy efficiency and install radiators or underfloor heating to stay cosy in the winter.
