What you need to know.
Use the same opening size, glass and weather conditions in both quotes. Some aluminium frames have a thermal break, an insulating layer that limits heat passing through the frame. uPVC frames also vary in shape and internal supports. Compare the actual systems offered.
How to choose for your home.
Ask each supplier for the full specification and relevant test information. Compare cleaning, repairs, written warranty cover and installation work along with the price.
Your practical checklist.
- Compare equivalent glass.
- Ask about frame supports and heat insulation.
- Review seals and drainage.
- Compare written warranty terms.
What to share with our team.
Send a photo of the window or door opening and the room around it. Write the approximate width and height in feet, inches or millimetres, and clearly mention the unit. Tell us what matters most: fresh air, privacy, mosquito mesh, easy cleaning or space saving.
The team will confirm the final size, suitable materials, price and installation work. If your project needs an engineer’s approval or special safety requirements, discuss these before placing the order.
