Selecting your storm door sounds simple, but actually there are many factors to consider.
Are you looking for a storm door that vents from the top? Bottom? Full Vent? Security? Has a pet door?
Consider the type of hardware, how it will be used, and for what purpose you want it to serve when selecting your storm door. The finish on the door as well as the type of glass, and accessories like expanders, will help you in your final selection
Regardless of the features you want, Iossi can help you select the storm door that compliments both your home and your needs.
Newer doors often fit better and insulate better than older doors, and offer additional benefits regarding security, ease of operation, as well as taking your home occupants-including pets - into consideration. Today's doors offer the same beauty as well as being more efficient energy wise.
Key features to consider are energy efficiency, security, and visual appeal. All Iossi Doors are tested and researched to provide the best quality in each category, and we are experienced in the styles of home that each product is well suited to.
See our Getting Started Guide for additional tips.
All Iossi Door systems and components should be inspected on an annual basis for the following conditions:
Weather-stripping: If the weather-stripping fails to perform (i.e., snot sealing the door system properly, cracking, tearing, etc.) the weather-strip needs to be replaced. Remove the existing weather-stripping and replace.
Door Bottom and Gaskets: If the door bottom gasket fails to perform (i.e., splitting, cracking, etc.), the door bottom needs to be replaced with a new door bottom. If the sill gaskets on outswing sills fails to perform (i.e., splitting, cracking, etc.), the sill gasket needs to be replaced. Pull the existing gasket and replace the gasketing for proper functioning of the sill.
Riser for Adjustable Sills: If the riser for an adjustable sill fails to perform (i.e., splitting, cracking, etc.), the riser needs to be replaced. Remove the existing riser and replace.
Vinyl Thresholds: If the vinyl threshold fails to perform (i.e., splitting, cracking etc.), the vinyl threshold needs to be replaced. Remove the existing threshold and replace.
Corner Seal Pads: If pads are torn or missing, replace.
Sealing/Resealing Areas: If a caulk seal fails to perform (i.e., water leakage) remove existing seal and reseal areas.
GENERAL CARE OF YOUR STORM DOOR
GLASS: Wash glass using a household glass cleaner or warm water/mild detergent mix, and a soft cloth or paper towel.
LOW-E GLASS: Clean glass with a household glass cleaner using a soft lint-free cloth. To avoid streaks, do not try to completely dry the glass surface.
Removing Glass Stickers: Vegetable oil, WD-40, or Goof-Off, remover should remove the sticker. Follow up with regular glass cleaning instructions to remove any remaining residue.
DOOR FINISH: For general cleaning use either, liquid soap and water, Formula 409, Windex or Fantastik, Simple Green or a similar product. Always follow manufacturer's directions. Use a soft clean cloth, apply the cleaner and clean only a small portion of the surface. After cleaning, rinse the surface completely. NEVER use Acetone or products containing bleach, esters, ethers, ketones, aromatic and chlorinated hydrocarbons.
HINGES & HARDWARE: Hinges and door hardware may require occasional lubrication. A silicone spray lubricant or Lithium-based oil is recommended.
BRASS/NICKEL EXPANDERS: Wash expander using a warm water/mild detergent mixture with a soft cloth. Do NOT use a brass cleaner or steel wool as these products are not real brass or brushed nickel.
BRASS LOCKSETS & DEADBOLTS: A number of storm door models incorporate high quality brass component parts. As with all brass products, tarnishing will occur. Without proper care, brass can become stained so heavily that cleaning cannot totally remove the stain. In extreme cases of neglect, pitting can occur.
To clean, wash brass hardware with warm water/mild detergent and a soft cloth. Then apply a non abrasive paste wax on the brass hardware to help restore it's bright finish.
SOLID BRASS HARDWARE (select models only): If clear coat is damaged and tarnishing occurs:
