Insulating a Conservatory: Where Should You Insulate?

Jun 2, 2023

The most obvious target for insulation is the conservatory roof. Most of the heat in the conservatory escapes through the roof and most of the solar heat enters through the roof.

Insulating a conservatory roof requires you to either cover the existing roof with a new conventional tile or slate roof, or to install a lightweight internal insulation system.

In most cases, the ideal solution would be to properly insulate the roof ensuring that it adheres to building regulatory standards with a U-value of at least 0.15. This will certainly make a difference to your conservatory both summer and winter giving you the perfect room to enjoy with the family whatever the occasion.

Elsewhere in a conservatory, the walls – which are actually windows – should not be tampered with for insulation purposes. Unlike with insulating a wall inside your home, the only realistic options here are thermal insulated curtains or blinds. It is likely they will not be needed across the whole windows and usually installing these to the north and east- facing windows will do the best.

The floor in most conservatories tends to have a hard surface, finished in tiles or wood. There is usually some understandable reluctance to rip it all out only to install some insulation, so consider rugs as a practical alternative.

Rugs laid on top the floor will give a greater sense of warmth. If you are particularly exercised about this issue, you might want to lay thin (6mm to 10mm) wood fibre insulation boards with the rugs over this. That would give a decent level of insulation, and both can be taken up and stored in spring/summer.

However, we do offer the option to go the whole way to upgrading your conservatory by replacing certain windows with an insulated wall or upgrading your windows to a better insulated glass unit, we particularly recommend using R9 from the Residence Collection, they ooze sophistication but also help keep energy loss down
