In 1865, Alfred Nobel, world-famous Swedish scientist, inventor and founder under of the Noble Peace Prize, established Dynamite Nobel, the company that developed TROCAL solid vinyl windows.

With energy savings uppermost in everyone's mind, many architects and builders are re-examining their traditional habits and ideas about window materials and construction and taking long hard look at TROCAL draft-free, multi-chambered PVC window systems.

With good reason, installation of TROCAL vinyl windows will provide an excellent method of keeping heat and cooling-loss to a minimum therefore cutting fuel cost. Over six million windows installed confirms this in every extreme of climate.

To begin with, each chamber in TROCAL's uniquely functional profile system is a miniature hermetically sealed air pocket, which provides additional insulation against heat conduction and helps resist condensation on the frame. A baffle internal drainage system assures effective seepage.

TROCAL offers tilt-turn, projected, casement, hopper, fixed light as well as cathedral or arch type windows. Also, a full line of double-hung and sliders are available in white and beige only.

The almost unlimited design freedom, acoustic quality, energy efficiency, beauty and durability leads many architects to specify the TROCAL PVC Window System.

TROCAL is solid vinyl, not just a layer. As a non-conductor of heat and cold, it it ideally suited for window frames, which TROCAL pioneered in 1955 in response to high European energy costs.
