At a glance, the look of exterior door systems hasn’t changed that much. But upon closer inspection, you might find they actually sport modern, innovative features to improve their performance on every level.
For starters, these four advancements are the main reasons why contemporary doors are more energy-efficient and secure today:
Contrary to the cheaper hollow-core units, ENERGY STAR®-certified door systems are solid on the inside. The wood core elevates their strength and enhances their insulating properties. A good case in point is the treated pine in the jamb of Renewal by Andersen® patio door units. As a result, they are tough and provide excellent heat resistance and soundproofing. You can’t say the same about all units.
2. Technologically Advanced Glass
Like replacement windows, contemporary patio doors use a cutting-edge glazing system to reflect excessive solar heat, provide great thermal insulation and block damaging, ultraviolet (UV) light. The best-performing ones have (at least) two panes, spectrally selective, Low-E coatings, a warm-edge spacer and an argon gas fill. The masterful combination of these key components is the secret to their exceptional energy ratings.
3. Multiple-Point Lock
Old-fashioned door systems only have one deadbolt that fastens one panel into the other. Now, many patio doors have a minimum of three locking points to render the interior impregnable. Our hinged French doors even have a five-point lock to provide greater security and reliability. On the other hand, our sliding units are equipped with a reach-out locking mechanism with an optional foot lock.
4. Continuous Weatherstripping
Experienced doors and windows company would say that swinging units are notorious for leaking inside air out and admitting unwanted drafts. Contemporary products don’t share the same deficiency. Weatherstripping is applied continuously around the opening to seal tiny gaps and prevent energy waste.
