Introduction: Managing Heat Gain To Gable End Glazing
Thank you for taking the time to talk with me about your project. Based on our conversation, I’ve put together this report to reflect what matters most to you. Inside, you’ll find examples of the systems we discussed, how they would work in your space, and what you can realistically expect in terms of performance and cost.
When you’re ready, you can book a TEAMS call with me and I’ll walk you through everything step by step.
The Area
- Gable End – Split into upper architecturally shaped glazing and Lower Fixed Glazing
- Upper Shaped Glazing 3500mm wide by 2100mm high (3no panels)
- Lower Fixed Glazing 3500mm wide by 2250mm high (3no panels)
- West Facing
The Key Priorities
- Dramatically reduce solar heat gain so this room can be used in summer
- Improved TV experience by managing light
- Protect wooden flooring and new furniture from sun damage fading
