Conservatory Insulations – Who Can Do It?

Naturally, the various kinds of conservatories each require their own specific best practices when it comes to insulation. The great news is that this can be done quickly and cheaply and is often facilitated by the structure of the existing conservatory. The smaller and medium-sized solid roof conservatories, for instance, might include spars to which wood can be easily attached.

This allows you to form a space that you can fill up with insulation material. This can later be covered with wallpaper to achieve a really beautiful finish.

Solid Roof Conservatories:

Aluminium spars are common with such constructions. They spread out from the centre of the roof and their job is to hold the roof up. However, the roofing of pre-built conservatories is often poorly insulated for this very reason. Metal spars are ready conductors of heat and cold and can seriously compromise your home’s thermal efficiency.

For this reason, it makes sense to provide a buffer between them and the roof above. Wood serves this purpose exceedingly well and simultaneously creates a space which can be filled with insulation.

Self-Drilling Screws

Self-Drilling and self-tapping screws are useful in that they will save you the drudge work of creating holes beforehand. Provided that your spurs are constructed with aluminium, a fairly soft metal,  driving these screws through the wood and aluminium layers shouldn’t be too challenging.

Important Measurements

1. Preliminaries: Measure the available space between the roof and walls to see how much is available before installing your new insulation. 

2. Wooden framework attaching to the roof:
Measurements should take into account the space between the roof and the wooden structure you are attaching to the spurs on the conservatory roof. In other words, the thickness of the wood is important for determining the thickness and area of the insulation material you wish to install.

3. Horizontal framework: Another factor to bear in mind is the wood which attaches horizontally to the walls to meet with these diagonal beams. You’ll need to make sure that this isn’t so low as to impinge on the door openings or window openings.

Sealing Gaps Between the Roof and Beams

Gaps can be sealed with aluminium tape to ensure that no condensation or drafts can pass through them later on.

Insulation foam boards

These are an easy option both from a price-point and practical point of view. They’re convenient to obtain from your local Home Depot and can be cut to size without any professional tools. It makes sense to invest in a product with an outside layer of reflective aluminium foil to reflect heat away from the conservatory.

These panels should be able to fit snugly when wedged between the wooden beams. If you cut them slightly too small, you can also use expanding foam to glue them to the roof of the conservatory. In that case, you can use some of the insulation tapes to hold them in while the foam dries.

You’ll then tape up the panels at the gaps to further improve thermal efficiency.

Installing the MDF Board or plywood over this insulation board provides a flush surface on which you can provide the finishing touches. Seal up the gaps in the plywood with silicone sealant.

A Luxurious Finish

Your stately conservatory is nearly completed, but be mindful to cover any uneven areas with specially cut strips of wallpaper. After that, you can begin to cover the remaining plywood with wallpaper to give it that decidedly soft and luxurious touch for which conservatories are so well adored.

Glass and Polyurethane Conservatories

You’d be forgiven for thinking that the glass walls are the first area of concern when it comes to insulating glass conservatories. After all, they make up the largest surface area of these constructions. The fact, however, is that the most efficient way to carry out the insulation on glass conservatories is to focus on the roof.

Conservatories are chilly in the winter months because of heat lost through the roof. On the other hand, it perfectly makes sense to install an operable window on the roof to deal with the greenhouse effect conservatories tend to generate in less shaded areas of the house.

Four Ways to Regulate Temperature:

Solar Control Films

The most cost-effective method for insulating glass is to make use of these. They are effectively large reams of stickers that keep the heat trapped inside your glass structure. Products like this work to filter out the sun’s heat while still giving your home that sunny look and feel. Now you can achieve better thermal efficiency while still appreciating your garden with an uninterrupted view.

Aluminium Foil

In more extreme situations where you feel some respite from the sun is in order, you can opt for something that creates a solid-roof feel. Granted, this is not ideal for those wishing to admire the open sky, but it is still a favourite of many conservatory owners. Another light-weight solution is to make use of thermal wadding.

Install a solid-roof

Considering that you’ll be integrating the conservatory into the house and giving it less of a garden feel, this option is not for everyone. However, skylights can be installed in such a structure, which can offer the best of both worlds. This is also the most efficient means of ensuring thermal efficiency and can give the house a very elegant feel as it blends into the garden without walls to obstruct its view.​
