How Businesses Custom Steel Windows & Doors Benefit San Diego
Benefits of Custom Steel Doors
One of the most important benefits of custom steel doors for businesses is that they are nearly indestructible. You can always depend on the security custom steel doors provide.
Another benefit is that steel is the most durable material for doors. This means your door can sustain large, heavy items being moved in and out of the building. Commercial steel doors are a great option for oft-used entrances.
Lastly, the high level of insulation of custom steel doors makes them energy-efficient. Portella’s steel doors feature a thermal coating to ensure maximum durability and tensile strength, which will keep your air conditioning and heating costs low.
The Thermal Window Difference
Thermal windows are a great cost-saving move for your home or business. Portella’s thermally broken steel windows with low e-glass are built with recycled material. They are designed to minimize the effects of UV rays, which will keep your home cool during the summer months.
Thermal windows also reduce sound transfer, allowing you to enjoy the ambiance of a room with minimal noise from the outside.
