U-Values – Why You Need To Know About Them

If you have recently visited any of Pennine’s showrooms or the showroom of any other local home improvement specialist you may have seen the U-Values achieved by certain products displayed.

U-Values may be something that are currently completely alien to you, but it is important to know what they are and how they can benefit you. Once you have familiarised yourself with them, you will then know what is required to better insulate your home.   

It’s quite simple really; a U-Value tells you how effective a material is as an insulator – the lower the U-Value, the less heat escapes through it.

Getting a grasp of U-Values enables you to compare the insulating qualities of different products; useful if you’re e.g. trying to a make a choice between a polycarbonate roof and solid roof when buying a new home extension.

A U-Value enables the accurate measurement of the insulating properties of applications and materials. Take a look at current UK building regulations and you will see that a certain overall U-Value must be accomplished when constructing or modifying a structure. This can only be established once the U-Values of the wall, floor and roof have been identified.

You can probably now understand the obvious thermal benefits of low U-Values, but what else will they do?

Well, the inside of your home will feel a whole lot warmer for starters as draughts will be less capable of getting in. This will help you save money on energy bills as it will cost less to heat the space.

At Pennine, we always inform customers about the U-Values delivered by our products and will make the effort to calculate the U-Value achieved for an entire building if a new conservatory or orangery is on your wish-list.
