The window frame material plays a critical role in the overall energy efficiency

It works alongside the glass glazing in a window to block transfer of heat. Despite good glazing, a window with poor profile material (if not sturdy and properly sealed) may not offer the required amount of insulation says Ashwin Reddy, MD, Aparna Enterprises Ltd.

What are the different kinds of sliding doors one can put to good use in a balcony?
Sliding doors are best choice when maximizing the available space inside the house is important. On one hand they take very less space for movement and on other hand their unique design helps in bringing much required natural light inside the house. Some of the top choices in Sliding doors are:

• Sliding doors: The sliding uPVC/Aluminium doors comprise of two or more frames that can slide horizontally, to the left or right on tracks. The doors are very smooth to operate since they are slightly raised above the track. This also prevents the dust from settling in the track.
• Slide and Fold doors: Slide and fold uPVC/ Aluminium doors are designed for maximum flexibility while providing a smart yet attractive look to your entrance. The slide and fold doors come with a sash which gives you the choice to move it in either direction or stack them to one end. The design isn’t the only aspect these doors have to offer as they are highly durable making them immune to extreme temperatures. They have the advantage of opening completely or partially, providing you with an adequate amount of ventilation and fresh air.
• Lift and Slide doors: Lift and slide Aluminium doors combine exceptional design with optimal performance. The sliding panel of the door operates on its own track, so no additional space is required outside or inside your home. The door can be locked for movement anywhere between the track. Just turn the door handle 180° to lock or release the door for movement.
• Slimline Sliding doors: Slimline Aluminium sliding doors offer slim profiles for sliding application, enabling wider sightlines and smooth door movement. Technologically advanced Slim Aluminium profiles handle larger panes of glass providing wider view and can be flushed to floor for wheelchair movement.

How does window frame material influence the window’s overall energy efficiency?
The window frame material plays a very critical role in managing the overall energy efficiency of the window. It works alongside the glass glazing in a window to block transfer of heat. Despite good glazing, a window with poor profile material (if not sturdy and properly sealed) contributes to poor insulation of the space and requires good amount of efforts to maintain temperature inside the given space, especially in extreme temperature conditions. Such windows also have need for regular and exhaustive maintenance to manage overall look and feel of the window. A window with quality uPVC or Aluminium profile on the other hand effectively insulates the given space and helps in maintaining temperature with minimal effort. Such windows also don’t require extensive maintenance and look good for years with just cleaning at periodic intervals.
