Specifications for standing seam systems which comply with specific, pre-determined thermal value requirements are available directly from Alumasc technical services on 01744 648400. These systems have been developed using complex computer modelling programs to provide a range of specific thermal performances.
There is no online software for calculating insulation thicknesses within the metals roofing section due to the nature of the construction, which employs a combination of support bars/brackets and halters, which produces a variable cold bridging effect.

Gutter Calculator
The Alumasc Drainage gutter calculator allows the user to choose from a range Alumasc eaves gutter profiles with sufficient capacity for specific roof areas. The user selects roof type, either gable, or hip roof. (With the hip roof option it is assumed that the gutter runs all the way round the building). Next enter the length, width and height of the roof (see diagram), select a location form the map, enter the proposed number of outlets and click calculate. For gable roofs, with one or two outlets, the option of end outlets can be selected if required. The available gutters in each Alumasc range are displayed by selecting the range from the pull down box.
If you have an area for the roof rather than a length and width, or if you have an additional area of roof draining onto the roof, simply click the 'lock area' button, and enter the total drainable area.
