BrochureQuick Guide

First in the Therma Tech™ line of insulated raised steel panel steel doors - quality, value, and style 

Choose from six classy woodgrain textured panel designs – Country, Cottage, Shaker and more, with our Therma Tech 3500.  The 2” thick panel, made with our 3-layer steel front and back construction and insulating polystyrene core, provides very good thermal efficiency (R-10.4 thermal rating).  Unbeatable protection against the elements is achieved through our thermal break / tongue and groove section joints, which create a weather tight seal. 

A Better model especially in terms of available customizations, twenty-six window designs plus nine glass options round out the expansive list of choices.  Hörmann window insert frames are recessed from the panel surface for a cleaner look, and tempered glass panes contribute to safety in case of breakage by keeping large shards of fragmented glass debris in check.  With seven attractive color options, you’re sure to find the look that matches your personal style.
