Loft glass doors with stick-on muntins versus steel framed doors with glass: which choice is better?

When you opt for loft glass doors, you often have a choice of glass doors with stick-on muntins or steel-framed doors. Today we will focus on the benefits offered by Icon Loft Steel Doors and compare them to glass doors.

Glass doors with stick-on muntins versus steel doors framed with glass: which choice is better?

I. Aesthetics and design

Glass doors:

  • Built on the principle of a hinged sheet of glass, with an imitation metal structure.
  • The glued-on muntins are only an imitation, which is visible at the gluing point and through the thickness of the glass.
  • The glass-mounted hinges are visible and protrude beyond the outline of the door’s “stiles.”

Steel doors:

  • Welded construction of metal profiles, with a rebated frame.
  • Frames filled with glass, without glued muntins.
  • No visible gaps, providing excellent sound and thermal insulation.

II. Robustness and durability

Glass doors:

  • Less durable and less secure compared to steel doors.
  • Stick-on muntins and glass panel-based construction may be more susceptible to damage.

Steel doors:

  • Durable steel construction for robustness and safety.
  • The weight of the door gives a feeling of luxury during use.
  • The rebated frame eliminates the occurrence of gaps, which affects the quality and durability of the door.

III. Insulation and functionality

Loft glass doors:

  • Design with glued-on muntins can cause gaps along the contour of the sash, through which light penetrates.
  • It may be less effective in thermal and acoustic insulation.

Steel doors:

  • No visible gaps thanks to the rebated frame, which provides excellent thermal and acoustic insulation.
  • Ideal for those who value privacy and quietness in their interior.

IV. Price and value

Loft glass and steel doors:

When choosing a loft door, it is worth considering the differences between glass doors with stick-on muntins and framed steel doors with glass. Glass doors may seem visually appealing, but they do not provide the same robustness and durability as steel doors. In addition, stick-on muntins and visible hinges can affect aesthetics. Steel doors offer full structural integrity, excellent insulation and a unique industrial flair. With similar prices on the market, it’s worth investing in a real loft door, which will not only be a stylish piece, but also provide durability, security and comfort of use
