Insulating door set with exclusive design:

In combining metal and insulating materials, DOORTAL has been able to design a range of doors with high thermal breakage values, while maintaining the strength of the door unit. ISOPLUS, the insulating door guaranteed for 10 years, is the benchmark in terms of mechanical resistance:

  • Steel frame in exclusive DOORTAL tubular profile
  • Door leaf in 15/10° thick sheet with internal reinforcements
  • Steel hinges with grade 14 stainless steel ball according to the EN 1935 standards

The ISOPLUS insulating and metallic door offers a recognized level of comfort, without sharp edges and with well-positioned seals. The absence of welding points on the door panel, contributes to the sober and elegant design of this insulating door set.

Insulating, thermal and acoustic door, all in one.

In the RT 2012 (thermic regulation) French law and the HQE (high quality environment) French process, or more generally in the sustainable development in the construction market, the ISOPLUS product range is made-up of three models of insulating doors. All of them benefit from the following performances:

  • ISOPLUS 2.1 : coefficient Uw 2,1 W/m².K
  • ISOPLUS 1.5 : coefficient Uw 1,8 to 1,4 W/m².K
  • ISOPLUS 1.2 : coefficient Uw 1,5 to 1,2 W/m².K

The lower the U coefficient, the more the heat loss is limited as well as the energy consumption. The results obtained on our insulation doors comes from the selection of the insulating materials creating a sufficient thermal break. In parallel every insulated doors benefits from acoustic ratings that are essential today, particularly with the requirements of the new acoustic regulation (NRA) and AEV rating that certifies its permeability to air, water and wind.

Insulated doors equipped with decorative panels:

In order to answer to architectural requirements, our metallic insulated doors have been developed to combine performances and architectural integration. With decorative covering elements, the ISOPLUS door becomes nearly invisible. Offset hinges are available depending on the thickness of the panels.
