Warm roof conversion

Warm roof conversion

You may ask, why do I need a warm roof conversion on my conservatory? Polycarbonate conservatory roofs and even glazed ones are prone to heat loss. We have all been in a conservatory in winter that is bitter cold and frankly unpleasant to sit in, and the opposite in summer. A scorching room requiring the door and windows to be opened constantly to keep the heat at bay.

There have been solutions along the way, polycarbonate inserts designed to reflect the heat either upwards in summer or down back into the room in winter. These inserts are fiddly, and some even block the light coming through the roof, negating the point of having the polycarbonate roof in the first place.

U Values

U values is a measure of how slowly a material passes its heat. The slower it passes its heat from one side to the other, the better the insulator it is. A lower U value is classified as a better insulator.

A typical high performance polycarbonate sheet will have a U value of around 1.2 W/m²

Some of the high performance glass we can supply can only reach a U value of 1.0 W/m², which is an improvement, but cannot match the warm roof conversion value of 0.18 W/m².

The difference between a warm roof conversion and polycarbonate or glazed roof will be quite noticeable and will make an all year round usable space. Provided of course the windows and doors fitted in your conservatory are up to date and properly installed.

Sentinel Roof

We have a Sentinel roof installed in our Bristol showgarden. A quick and easy roof to install with a fantastic low U value for warmer winters and more comfortable summers.

Its a warm roof conversion system based around pre-assembled timber pods. Using timber is a great way to cut down on condensation compared to other metal and composite alternatives.

Installation is straightforward and a waterproof roof is often achieved within a few hours of starting with minimal disruption.

Once the timber pods are installed the insulation can be installed. This is what really helps to lower the U value so much.

These roofs are supplied with high performance multi foil insulation. This has the ability to insulate the roof very well, whilst keeping the profile of the roof down, if you were to use solid foam insulation you would need to use over 75mm to reach a similar insulation value, this would mean a thicker rafter height and a lower ceiling height inside.

Sentinel warm roof conversion before plasterboard

We realise that a roof replacement will effect the light transmission into the room, so you can opt for roof lights to be designed into the roof. These will be supplied complete with flashing kits ready to drop straight into the precut holes.

The inside is now ready to be wired up if you are having any lighting/speakers in the roof. After that the plasterboard is cut and fitted, then plastered.

To finish, lightweight tiles are supplied in a style and colour of your choosing. You have a choice of slate effect PVC tiles that are a fantastic alternative to real slate, or a lightweight steel tile which has an extremely hard wearing surface.

Watch the transformation in this short video. This was completed in testing weather conditions over 1.5 days. the speed of which this went up to a watertight point meant that disruption to the room/house was at a minimum and the rain didn’t affect things too badly.
