Fibrex Vs Ultrex Windows

Fibrex is a composite frame material for replacement windows current manufactured exclusively by just one window maker, which has been in the business for over a century. The material provides and is marketed to upscale home consumers with a price point considered the highest in the windows replacement industry.

Disadvantages of Fibrex Material Type

With tens of millions of dollars, Fibrex is a patented proprietary mix of reclaimed wood fiber (sawdust) from Andersen’s own manufacturing waste and a special thermoplastic polymer (vinyl), some of which is also reclaimed. Because of this, Fibrex windows combine the strength and durability of wood with the structural resilience and maintenance ease of vinyl. The Fibrex frame is manufactured with chambers and cells like the best vinyl frames for insulation purposes.

The one real disadvantage of Fibrex windows is its premium price, considered the highest among all window frame materials, and the fact that there’s only one company that manufactures it, which makes distribution less than widespread.

Infinity^® replacement windows and doors are made from Ultrex fiberglass – a kind of reinforced fiberglass material that’s so strong and durable it performs better than other window materials. Best of all, it means that Infinity products are virtually maintenance-free.

Our patented process begins with strong glass cables saturated with specially compounded resins which are then pulled through a heated die before being cut with diamond-edge blades. You can see below the steps that Ultrex goes through, from forming and curing all the way up to cutting. These steps help ensure the creation of a remarkably durable material able to outlast and outperform other materials used for windows.

ADVANTAGES OF ULTREX

• Low maintenance
• Silica sand – an abundant natural resource – is used as a base material
• Intricate profiles that replicate the look of traditional wooden windows
• Low expansion which means easy operation and longer window life
• Strength helps windows keep their shape
• A narrow profile that allows for more visible glass area and a bigger view
• Long-term stability, reducing the risk of seal failures and air leakage
• Patented, mechanically bonded inline acrylic finish that’s up to 3x thicker than competitive finishes, therefore providing superior resistance to discoloration, scratches, and dents
• 8x stronger than vinyl – one square inch can support 41,000 pounds!
• Fiberglass windows have a 38% longer useful life expectancy compared to vinyl
• Infinity windows with Low E glazing can reduce heating and cooling bills by as much as 30%.

Durability for a lifetime

Ultrex is as strong as low carbon steel and is up to 8 times stronger than vinyl – in fact, it’s so tough we need to use diamond-edge blades just to cut it to size. The strength of Ultrex means superior stability, long-term ease of operation, low maintenance, and superior performance.

Strength for an expanded view

Our patented process begins with strong glass cables saturated with specially compounded resins which are then pulled through a heated die before being cut with diamond-edge blades. You can see below the steps that Ultrex goes through, from forming and curing all the way up to cutting. These steps help ensure the creation of a remarkably durable material able to outlast and outperform other materials used for windows.

Ultrex Performance

Cold, heat, and time – no worries
Ultrex resists the effects of cold, heat, time and pressure to provide homeowners with the most worry-free windows and doors currently available. In comparison, extreme heat can make vinyl distort, while fluctuating temperatures can cause it to crack. Infinity products, though, offer the highest possible level of performance and are virtually maintenance-free.

Low thermal expansion means a stronger seal

Ultrex’s thermal expansion rate is extremely low, which means it keeps the window stable and weathertight – thus reducing the risk of seal failures and air leaking into your home.

Tired of windows that are difficult to operate?

The low expansion of Ultrex means Infinity Windows resist sticking, swelling, and warping, providing easy operation for the life of the window.
