The cutting-edge fiberglass framing systems of Alpen HPP offer superior performance to conventional fenestration materials in a number of ways: durability, stability and efficiency. Over the past 10 years, fiberglass has been used more and more in residential and commercial construction. It is becoming the preferred material for window frames and door panels. Advantages of

Triple Pane vs Suspended Film The transition from single pane glass to dual pane (with a single chamber) provided an improvement in window energy performance. In much the same way, the introduction of multiple-chamber glass packages – with two to three insulating chambers and multiple surfaces using lightweight, suspended film layers – allow for significant

It is easy to maintain the beauty of your windows. Alpen Windows and doors are virtually maintenance free. However, as with any product exposed to atmospheric conditions, they will become dirty and require cleaning. With very little effort your windows and doors will retain their “just new” look for years to come. In most cases,

How to Measure Performance R-Value: a measure of the resistance of a glazing material or fenestration assembly to heat flow. It is the inverse of the U-factor (R = 1/U) and is expressed in units of hr-sq ft-°F/Btu. A high-R-value window has a greater resistance to heat flow and a higher insulating value than one

Alpen Windows’ unique framing and super-insulating glass system incorporates a combination of key technologies and best manufacturing practices to deliver high performance. Our super-insulating windows are built with highly insulating fiberglass frames, and spectrally selective Low-E coatings, inert insulating gases and warm edge technology that control temperature gains or losses. Glass is naturally considered to

R-Value is a measure of thermal resistance used in the building industry. A high-R-value window has a greater resistance to heat flow and a higher insulating value than one with a low R-value. R-value is the inverse of the U-factor (R = 1/U) and is expressed in units of hr-sq ft-°F/Btu. Full Frame R-Values The

Temperature Gains and Losses There are multiple factors that affect the ability of a window to control heat gains and losses. In the winter you want a window that gains heat and keeps it indoors; in the summer you want a window that loses heat and prevents it from entering your home. So how can

According to ENERGY STAR, air leakage accounts for 25% to 40% of the energy used for heating and cooling in a typical American home.* What is Air Infiltration? Air infiltration refers to air leakage through unsealed joints in a structure and around the windows. A leaky home allows unwanted cold air to seap indoors during

Glass is the most common and least understood material in the construction industry. Selecting glass is one of the most important and far-reaching decisions in a commercial project. The choice impacts human comfort, energy efficiency, productivity and overall design aesthetics. It also affects mechanical HVAC design and loads, daylighting, interior condensation control, ultraviolet fading and

There are many components to an energy saving window and it can be difficult to really know what differentiates one window from another. Alpen HPP has paid particular attention to every aspect of a window and has carefully engineered some of the best performing super-insulating windows on the market. We understand that super-insulating windows and

For optimal performance and longevity, regularly clean the interior and exterior surfaces of your AlpenGlass™. Click here to download your copy! Step-By-Step Cleaning Instructions: Wet the glass surface with a combination of soap and clean water to eliminate excess dirt and debris. Apply a mild, non-abrasive window cleaning solution with a non-abrasive applicator to clean
