Energy-saving vinyl windows
with steel reinforcement
Safe, efficient, hard-wearing: steel-reinforced vinyl windows and french doors from HBI
Energy-saving vinyl HBI windows are a safe bet when building or renovating a home. And not just in one sense, either, but in three different ways:
High energy efficiency with HBI triple glazing
# 1 Energy savings. Steel-reinforced vinyl HBI windows come in two thicknesses: 70 mm and 80 mm. Larger thicknesses do more than just improve the frame's R-value. They can also accommodate stronger, better insulating triple glazing. This lowers your energy costs and raises the value of your property.
Better stability and burglary protection
# 2 Burglary protection. Vinyl HBI window frames are traditionally made from high-density PVC. However, HBI increases the frames' structural integrity even more during production by reinforcing the sashes and frames with multiple generously sized galvanized steel plates. These plates, when combined with integrated corner braces, can make even french doors with large glass panes exceptionally stable – and highly secure against intruders.
Low maintenance and durability
# 3 Cleaning and quality. HBI uses high-quality, easy-to-clean extrusions. Its cadmium-free multi-chamber extrusions are highly weather-resistant and painless to maintain. The smooth, closed high-definition extrusion surfaces minimize soiling and protect your HBI window from long-term dirt accumulation. For added protection, all extrusions are anti-statically treated and effortless to clean with common household detergents. Spend more time enjoying your vinyl HBI windows – and less time cleaning them.
