Educating customers on the correct glass specification for their home’s orientation is crucial as it can affect the temperature and energy efficiency of the room. Therefore, it’s important to consider the type of glass you choose.
Wendland roofing systems can be used with a variety of glass options which come in various specifications and colours.
U-Value
The U-Value measures the amount of internal heat loss, and a lower number indicates better insulation.
Light Transmission
Glass can allow only a certain amount of natural light to pass through, reducing its impact and providing increased comfort.
Solar Rejection
The level of solar energy that the glass unit reflects. Our glass options reflect about three times more solar energy than standard glass.
UV Protection/Rejection
By reducing the impact of harmful UV rays, our glass can provide greater protection for furniture and fabrics.
Cleaning
A coating uses the power of the sun to actively break down organic materials, which are then washed away by rainwater, resulting in significantly reduced maintenance requirements.
Colour
Glass is available in a range of colour options to match your customers’ design preferences.
Locations facing north or east tend to be cool and shaded, with minimal direct sunlight. Glass with high light transmission and low solar rejection is a great choice as it will allow more light and heat to enter the room.
South or west facing locations receive ample sunlight throughout the day, resulting in bright natural light. However, excessive heat can cause the room to become uncomfortably warm so choosing the right glazing is crucial to avoid this.
We suggest using glass which has low light transmission and high solar rejection properties and we have glass options with a U-Value of just 1.0, making them three times more energy-efficient than standard glass units.
The position of a roof can have a direct impact on the design. South facing sites receive more sun than North facing. The need for ventilation and shading will also vary and effect the choice of glass.
The % of solar gain is the measure of how much solar energy passes through the glass e.g. Ultimate Blue has a 18% solar gain meaning 82%of the solar energy is rejected and will not pass through.
