Pre-Assembled Door Systems

“The installation of Therm-All’s pre-assembled door systems is a snap. From the crate to the install is virtually no time at all.” –Tim Allison, VP of Project Management, Barnes Buildings.


Therm-All Pre-Assembled Door SystemsPre-assembled doors from Therm-All are completely assembled under factory-controlled conditions. Additionally, pre-assembled doors are custom built to your job specifications, so they fit like a glove.

We’ll also ship your doors with your insulation order. This means that you get the product only when you need it, and your doors won’t sit on the jobsite for weeks while the building is erected.

Therm-All pre-assembled doors:


Metal Building Doors

Therm-All’s pre-assembled steel doors are designed specifically for metal buildings. Doors are finished painted in either white or brown. Additionally, metal building doors come with an adjustable weatherseal (composed of polyethylene clad urethane foam) which has a rain drip on the outside face.

Existing Opening Doors

Whether you have a masonry, wood or steel opening, Therm-All has the door system for your existing construction application. These doors are designed to anchor to a variety of wall conditions. All of the options that are offered with metal building doors are also available on existing opening doors.

Glass Storefront Doors

Therm-All glass storefront doors are offered in a variety of finishes, glazing and hardware options, sizes and sidelites.

Fire-Rated Doors

Therm-All fire-rated doors are available either as a 90-minute (B-label) or as a 3-hour (A-label) rating. All the components used on each rated system comply to meet the rating criteria.

Wind-Rated Doors

Therm-All wind-rated doors have been tested for impact and rated for a design pressure of +/-50 psf. They are certified with a Florida Product Approval Number. All of the components used in the door system as well as how the door is anchored into the opening meet this criteria.

“I like that you can put in Therm-All doors and windows after the fact. The customer doesn’t have to make the decision far in advance. It gives the owner a lot more flexibility.” –Don Fryklund, President, Fryklund Construction.
