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
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
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
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
More than 35 companies worldwide now manufacture commercial, institutional and residential “multi-chamber” IG units based on a performance array of crystal-clear, low-emissivity films suspended midway between two panes of glass. In its leadership role among all worldwide Suspended Film (SF) fabricators, Alpen HPP insulating glass units, are certified by the Insulating Glass Certification Council (IGCC).
There are three important wavelengths to consider when selecting windows and glass: UV, visible light, and infrared. UV wavelengths can cause sunburns and fading in fabrics, and should be blocked; visible light is light that we see and should not be blocked; infrared wavelengths transfer heat (these are the wavelengths that make your car too
Passive solar heating is utilized in multiple design approaches and focuses on how combining various building elements in strategic ways can positively contribute to the heating, cooling, and daylighting of a building. Glazing is one of the most critical considerations for effective passive solar heating designs. Taking into consideration the orientation of a building’s windows
