Bifold Hangar Doors Alternative

Bifold hangar doors are commonly installed on small private hangars or “T hangar” developments. They have always been an economical solution for small openings.  But for larger width hangar door openings, are they the most economical solution?
In our article Bifold Hangar Doors, Spec-Dor looks at some of the common problems associated with bifold hangar doors when they fail.  The article also looks at the hidden costs with bifold doors due to the impact on the building structure and how this impact increases as the width of the hangar opening increases.
Spec-Dor proposes its new ECO bottom rolling hangar door as a cost-effective alternative to the bifold hangar door. We take a look at the installation at Central Aviation's new hangar at Sprinkbank Airport outside of Calgary.

The new hangar required an opening of 80ft wide by 19ft high.  Spec-Dor installed their new ECO design 4-blade Slide-to-one-side hangar door solution.

Bi-Parting Hangar Doors - Southern Design

SpecDor designed, built and installed the hangar doors at the Associated Painters maintenance hangar in Spokane, Washington.

The opening of the building was 180 feet (54.86 metres) wide by 48 feet (14.63 metres) high.  As there was no provision in the building design for door pockets,  there was no space inside the building to store the blades when the doors were open.

SpecDor proposed a bi-parting Southern configuration solution whereby the doors are stacked outside the building.  They were able to provide drawings for an alternative bi-parting Northern configuration solution.  Find out why the Southern design was chosen and the benefits of each design in the article Bi-Parting Hangar Doors for Associated Painters, Spokane
