Glass sliding door

Hi there, This is my first post so hopefully I can keep within the guidelines! I am currently an audio engineering student at SAE in the planning stages of building a small (approx. 8x4m, 3m height) studio. The studio will be located rurally so isolation won't be as critical. However I would like to put a sliding glass door in one end of the studio (live room end) partially for aesthetics but also to provide easy loading of equipment in and out. My concern is that this will become an isolation weakpoint, more in respect to occasional vehicles that drive by than sensitive neighbours. I considered a large heavy curtain that covers the door (inside) but wonder if this would achieve much? Is there any other way to go other than an expensive double glazed door? Thanks for any suggestions, I look forward to continued scouring of this site...

what kind of noise are you getting from traffic currently? does the existing structure block it? if so, then you'll need a door (or perhaps 2 doors) with enough mass and properly sealed construction to match the existing construction.

Hi there, thanks for the reply. Just to clarify this project is still in the planning stages. Also i should probably clear up that it will be a free standing structure away from other buildings. The 'traffic' is only occassional farm vehicles. I am hoping to use 21mm triboard on the internal walls with regular stud arrangement and around 12mm ply on the exterier, with 100mm semi-rigid glass as insulation. The floor (on piles) will be 18mm particle board but will have an additional timber flooring in the live room and raised floating floor in the control. The roof will most likely be tin over 200mm rafters with a suspended jib (plaster) or ply ceiling, obviously with appropriate insulation in the ceiling space (batts or semi-rigid glass). The sliding door in question is an external door that opens into the live room. What sort of STC rating could i expect from a standard sliding door? Obviously budget is an important factor in all my considerations, so don't want to mop up mega-cash on a door, ha, cheers
