# What is a good U value for conservatory roof?

Contents

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.

## 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.
