A u value calculated by us should be sufficient to satisfy the requirements of building regulations.
We can advise on how you might achieve the required standard.
Obviously improving the individual u factors in the calculation will improve the overall thermal performance.

This is different than r value that would be used to determine the energy efficiency of just the window pane thus a window with a u value of 1 is more energy efficient than an window with a u value of 5.
Our u value calculator is a whole window calculator designed to calculate an accurate u value of windows and doors.
U values are used to determine the insulating efficiency of the window and all of its components.
U factor is the rate at which a window door or skylight conducts non solar heat flow.
It s usually expressed in units of btu hr ft2 of.
This glass specification will produce a glass unit with ug value of 1 0 1 1 w m 2 k.
This calculated value conforms with bs en iso 10077 part 1.
There are various ways of improving the uw value of an installation.
