Upstands are designed to be used in conjunction with our dome rooflights to provide a thermally broken interface which in turn helps to improve the overall thermal efficiency of the roof. Our upstands are insulated PVC and they are excellent value for money. Upstands enhance the overall appearance of the rooflight and are prefinished white internally, therefore requiring no further decoration.
