Energy Efficient OPENINGS Solutions
Experts agree that as design and development continue to trend towards energy-efficient performance, operating costs and carbon footprints will decrease. The outer envelope is the key to an eco-friendly building, and by their nature, windows and doors represent an important part of the equation. The insulation level of an opening can be expressed relative to 2 different standards: ASTM C518: Standard Test Method for Steady State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus. ASTM C1363: Standard Test Method for Thermal Performance of Building Materials and Envelope Assemblies by Means of a Hot Box Apparatus.
DE LA FONTAINE offers insulating doors that, when combined with a thermal break frame, contribute to a considerable reduction in a building’s energy costs. The thermal break frame is a special profile with a polyvinyl chloride (PVC) seal that inhibits the transfer of heat/cold from the exposed to the non- exposed side of the frame. This seal is also installed in the mullion of elevations and borrowed lites. Mullions can be filled with insulating mineral wool.
Please refer to our individual Door Series or to the technical data sheet on our website for complete information on testing procedures and energy values for DE LA FONTAINE products.
Sound-Deadening Openings (STC) Solutions
Sound-deadening doors and frames are necessary in many commercial buildings, such as auditoriums, offices, hospitals, schools, and multi-housing buildings. They limit the intrusion of noise into a room and ensure both quiet and privacy. DE LA FONTAINE offers a sound-deadening opening with a maximum STC rating of 47, in compliance with ASTM E90 and ASTM E413.
