What is a good U value for conservatory roof?

However, the typical U-value of a conservatory roof is in the range 1.1 to 1.7 and the poorer the level of insulation then the faster the warm air at the ceiling turns as cold as the air outside.

What is the U-Value of a conservatory?

Glass Conservatory Roofs

You can expect a standard double-glazed panel to have a U-value of around 3 W/m2k, whilst a triple glazed panel with Xenon filled cavities and low-e coatings will have a U-value of around 0.4 W/m2k.

What is the most energy efficient conservatory roof?

Hybrid roofs

Made from a combination of solid and glass roof panels, the vaulted ceiling is highly energy efficient and reflects heat back into the room. As well as keeping out the cold, this roof will create a beautiful light-filled room that maintains a comfortable temperature for 365 days a year.

What is the U-Value of a polycarbonate conservatory roof?

A typical polycarbonate roof has a U-Value of between 2.4W m/2k and 1.6w m/2k, thus resulting in the too hot or too cold scenario is far too common amongst conservatory owners. The Ensign WarmDek roof has a U-Value as low as 0.18w m/2k this is likely to save you lots of money on your ever increasing energy bills.

How do I find the value of my roof?

U-value formula

U Value is the reciprocal of all resistances of the materials found in the building element. To calculate the U-Value of the building element the R-Value of all the different components that make up that element will be considered. U-Value (of building element) = 1 / (Rso + Rsi + R1 + R2 …)

What is Au value?

A U-value is a sum of the thermal resistances of the layers that make up an entire building element – for example, a roof, wall or floor. It also includes adjustments for any fixings or air gaps. … The lower the U-value, the better insulated the building element.

Are solid conservatory roofs worth it?

The most obvious benefit of a solid conservatory roof is improved insulation. The space will stay warmer in cold weather, and keep off the strongest sun in summer. The value you will get from having an extension to your living space that is usable all year round is considerable – prospective buyers will think so too.

How long does a polycarbonate conservatory roof last?

Polycarbonate Roofs

The average lifespan is between 10 to 15 years. One of the major issues with a polycarbonate roof is the lack of proper thermal insulation. Conservatories with this type of roof often get far too cold in the winter, and too hot in the summer.

Are tiled conservatory roofs any good?

Solid or tiled conservatory roofs

A tiled roof will give you less daylight than glass or polycarbonate, but it will transform your conservatory into a proper extension of your home. Its thermal efficiency is in a totally different league, so you can use it all year round without worrying about the temperature.

Can I plasterboard my conservatory roof?

It is possible to fit insulation and plasterboard inside an existing polycarbonate or glass roof, however there are various risks involved. You may find that condensation builds up on the underside of the glazing during the winter. … Furthermore, conservatory roofs do not tend to be built to last.
