Door Threshold / September 18, 2018 / Pauline Francoeur
When youre satisfied that the door system is in the correct position drill through the thickest part of the hinge jamb with a regular drill at the hinges areas and then further drill into the cinderblock with a hammer drill. Drill the strike jamb in the same corresponding locations with the middle drilling positioned between the strike and deadbolt mortises. Countersink jambs holes to flush the masonry screw heads. It may be necessary to remove the door from the hinges for this step just remember to check the indexed jambs alignment to be sure nothing has moved. Remove shims and then remove door system from the rough opening. This must be done to install the plastic expansion sleeves into the holes drilled into the cinderblock.
The front entryway including the door jambs and threshold is the focal point of your clients home. It sets the tone and expectation for the rest of the home and it can add or detract curb appeal. Entryways have been important dating as far back to the Greeks. According to Jesse Nevins of Coastal Carolina University "To ancient Greeks doors were considered sacred and surrounded with superstition. So much so that doors and the comprising parts had their own deities. For the Greeks a door was not simply a way to enter a building but a holy place itself worthy of the highest respect." Keeping doors jambs and thresholds looking great while a home is under construction or remodeling is important and is now easier than ever.
This calculation is based on the specification of the double glazing together with the profile design and dimensions to determine the insulation benefits of the door measured in U-values with the lower the value the better the insulation achieved. The minimum acceptable under current building regulations for replacement doors is a 1.8 U-value but some local authorities will insist on lower values particularly for new build extensions. 2. GLASS SIGHT LINES Another important consideration should be the sight line or width of door profiles between each panel of the folding sliding door as this will affect the visible glass area available when the door is in the closed position. Most bifold doors are designed with dedicated profiles to minimise these sightlines as much as possible but some timber and many upvc folding doors use wide chunky profiles that produce very broad sight lines in excess of 200mm wide that will ultimately spoil your view.
