Which is more economical to install fibrous duct board or flex duct?
Fiberglass Duct Board is cheaper to install than Sheet Metal Ducts. This is definitely the choice of most builders if you don't know any better. Your Air Distribution Duct System should look like a tree ... comprised of a Main Trunk and Branch lines from that trunk. The trunk should bet smaller as it passes every several branches in order to maintain the pressure. Each branch line should have a manual damper (valve) to regulate the volume for balancing. Then you can eliminate hot and cold spots. All joints should be sealed with mastic and UL 181 rated tape. The biggest problem is that while it may look good, its structure gets less rigid (spongy) and interior lining is disgusting after just a few years of normal use. It's literally falling apart after 5 years. Almost every client of mine whose home has a duct board (did I say cheap) system complains of allergies and excessive dust. The only benefit is that when you finally decide to install a safer, more reliable, once-in-a-lifetime metal system, the duct board system can usually be removed in less than an hour with just a knife. Then it is placed in trash bags to remove it from the house without getting airborne particles everywhere. The only good use is when you want to line a return (with the foil side facing you) for additional insulation purposes. The only thing worse than ductboard is a duct system made of Flexible main trunks connected to small duct board triangles being used for sub-distribution into smaller areas.Whoever dreamed that one up was really looking to rip you off. mrgeothermal.com
Septoplasty?
DefinitionSeptoplasty is surgery to correct any problems in the nasal septum, the wall inside the nose that separates the nostrils.See also: RhinoplastyAlternative NamesNasal septum repairDescriptionMost patients receive general anesthesia before septoplasty. This will make you unconscious and unable to feel pain. Some have the surgery under local anesthesia, which numbs the area to block pain. You will stay awake if you have local anesthesia. Surgery takes about 1 to 1 ? hours. Patients usually go home the same day.Your surgeon will make a cut inside the wall on one side of your nose.The mucus membrane that covers the wall will be lifted up.Then your surgeon will remove or move any cartilage or bone that is causing the blockage in the area.After this, your surgeon will put the mucus membrane back in place. This membrane will be held in place by stitches, splints, or packing material.Why the Procedure Is PerformedThe main reasons for this surgery are:To repair a crooked, bent, or deformed nasal septum that blocks the airway in your nose. People with this condition usually breathe through their mouth and get infections on their nose.Uncontrollable nosebleedsTo repair a hole in the nasal septum. This is called nasal perforation.People who snort large amounts of cocaine or other drugs over long periods of time may need septoplasty. Snorting drugs can damage the septum.RisksRisks for any surgery are:Allergic reactions to medicinesBreathing problemsHeart problemsBleedingInfectionRisks for this surgery are:Return of the nasal blockage. This would require another surgery.ScarringA perforation, or hole, in the septum wallChanges in skin sensationUnevenness in the appearance of the noseSkin discolorationFluid buildup in the noseBefore the ProcedureYou will meet with your anesthesiologist (the doctor who will give you your anesthesia medicine and monitor your condition before, during, and right after your surgery. You will discuss your medical history to help determine the right amount and type of anesthesia to use. You may be asked to stop eating and drinking after midnight the night before the procedure.Be sure you tell your doctor or nurse about any medicines you take, evendrugs, supplements, or herbs you bought without a prescription. Also tell your doctor if you have any allergies or if you have a history of bleeding problems.You may be asked to stop taking any drugs that make it hard for your blood to clot 2 weeks before your surgery. Some of these are aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), and some herbal supplements.After the ProcedureYou will go home on the same day as surgery. After surgery, both sides of your nose may be tightly packed (stuffed with cotton materials) so you do not get nosebleeds. Usually this packing is removed 24 to 36 hours after surgery.Outlook (Prognosis)Most septoplasty successfully straighten the septum. Breathing often improves.ReferencesKridel RWH, Kelly PE, MacGregor AR. The nasal septum. In: Cummings CW, Flint PW, Haughey BH, et al, eds. Otolaryngology: Head & Neck Surgery. 4th ed.
