2. Thermal Efficiency: Secondary glazing can decrease heat loss through windows by approximately 65%. Experts use Low-E (low emissivity) glass to show heat back into the room.
3. Condensation Control: By offering a tight seal on the internal side and enabling the external window to "breathe" a little, professionals can effectively remove the relentless condensation that pesters numerous older homes.
4. Security Enhancement: An additional layer of glazing acts as a significant physical barrier to burglars. Professionals frequently utilize strengthened or laminated glass for added safety.

• Style and Specification: Decisions are made relating to glass density (e.g., 6.4 mm acoustic laminate vs. 4mm toughened) and frame color matching (RAL colors are frequently utilized to match existing paintwork).
• Precision Manufacture: Frames are custom-made in a factory setting to the precise millimeter.
• Installation: The professional sets up the frames into the window reveal. A "lumber sub-frame" is often used to guarantee the aluminum system has a completely flat surface to install to, which ensures an airtight seal.
