PR-60 Pyramid Brings Daylight To A Historic New England Wood Retrofit

PR-60 Pyramid Brings Daylight To A Historic New England Wood Retrofit

The 475 team recently traveled to Hanover, NH joining up with LAMILUX partners to assist in the installation the LAMILUX PR-60 Pyramid skylight in a retrofit of a historic home. This fully customized roof light transformed the interior kitchen space. Commitment to performance is standard for LAMILUX, and is reflected in all stages of this unit. This installation is a great educational tool to learn about the importance of each layer as it comes together, from the frame profile to the drainage and flashing.

Daylight Without Compromise

The PR-60 is a fully-customizable roof glazing system that can accommodate roof pitches ranging from 2 to 90 degrees, and can take a wide variety of shapes and forms. The Hanover house features of a 5 ¾ ft by 13 ft hipped roof light with a 30 degree inclination. Like all PR-60 systems, it consists of thermally broken aluminum frames with triple-pane, argon-filled glass, offering a U-value of 0.12btu/hr/sf and a solar heat gain coefficient of about 30%. Each pane is unique: the inner layer is laminated glass, the middle layer float glass, and the exterior layer tempered safety glass. The entire unit is rated for fall through protection, and can be walked on for maintenance purposes. But all of this protection doesn’t diminish the unit’s capacity to flood the space with brilliant daylight: the visual transmittance of the entire assembly still reaches about 60%.
