Develop a design project for insulating tooms, walls, floors and other surfaces. Select a premise type and adjust its dimensions, then add insulation layers and automatically calculate the amount of material, probable costs, etc. Check such parameters as Transmission Loss or Weighted Sound Reduction.

INSUL is a program for predicting the sound insulation of walls, floors, ceilings and windows. The programme can make good estimates of the Transmission Loss (TL) in 1/3 octave bands and Weighted Sound Reduction Index (STC or Rw) for use in noise transfer calculations.
