Many exterior doors – especially wood exterior doors – are problematic due to the nature of being exposed to the weather and environmental changes of heat and moisture. Exterior facing doors become even more challenging if they are over 7 ft tall or 3 ft wide.

Large garage doors are the best example of what can be possible with would have previously been thought of as impossible doors. That is to say doors that were too large were assumed to have problems because all big doors fail. Even so, to minimize failure, they are manufactured using very heavy materials and expensive hardware to mitigate the failing doors, only to add more stress and strain on the existing structure. In this regard, the big door business is lucrative, due to the ongoing maintenance contracts associated with large door problems.

Insulated Doors

True space separation between two adjoining areas (i.e., interior and exterior) is a difficult expectation for any door. Even though a door might looks attractive from a distance, the truth of the matter is seen from the other side of the door. The built-in insulation inside the patented Sing door core not only provides effective climate control, but offers advanced sound deadening qualities. Sing door cores have been used inside soundproof doors and everything from bulletproof doors and fireproof doors.

Save Energy

Why waste energy by having a door that doesn’t seal properly as your exterior door? Everyone knows that a good door seal helps prevent energy loss saving on energy consumption. Having warp-free doors means your doors seal properly without leaking every time, regardless of the season, temperature or time of day. You can save energy – not only from the insulated that is packed inside for better temperature control – but also from having a secure door seal that does not fail due to warping, if your door has SingCore inside.

Sliding Door or Pivot Door

Reduced to its simplest form, these insulated warp-free doors could also be exterior sliding doors and/or exterior pivot doors with all the same great characteristics that come with having SingCore inside.
