As codes become more stringent on thermal performances, we take our service to the next level by working with our manufacturers to insure code compliance through NFRC testing and certification. NFRC testing alone is not code compliant, so project specific thermal analysis is critical. MJD now offers CMA bid reports for many of our product lines to assist design professionals in code compliant product selection. We have also taken our thermal analysis a step further by specifically addressing installation of our product into the building envelope and how best to maximize performance. Therm Modeling is available to our clients to better assist in developing proper installation techniques which in turn maximizes overall performance.



Architects can leverage our experience and manufacturer's resources by using our promotional services which include, on-site project walk through, Auto Cad detailing services and project specific budgeting. MJD also offers assistance with custom application design, custom extrusion design and product integration into surrounding conditions.


MJD has implemented a maintenance program for building owners to service their windows, curtain walls and entrances. We utilize the available product warranties from the manufacturer to reduce material costs for the building owner. We also address out of warranty products by buying direct from the manufacturer. This results in competitive pricing for our services to allow School Districts and other public facilities to afford our Maintenance Program. We have many satisfied clients that have saved a great deal of money by maintaining and not replacing.
