What to Look for in a Window Supplier

When selecting a window supplier, it is essential to prioritize thermal performance to enhance your building's energy efficiency. High-quality windows with excellent insulation properties reduce heat loss, lower energy bills, and contribute to a comfortable indoor environment. Look for suppliers who offer thermally broken windows, as these materials provide superior thermal insulation. Additionally, consider the amount of glazing, with double or triple glazing options offering enhanced thermal efficiency and noise reduction.

For projects involving Structural Insulated Panels (SIPs), which are known for their outstanding thermal performance and energy efficiency, it is crucial to choose windows that complement these attributes. Formance can assist with thermal modeling through the Passive House Planning Package (PHPP) to ensure optimal performance.

The placement of windows within the wall is another important factor. Recessing windows into the insulation line can significantly improve thermal performance by reducing thermal bridging and enhancing overall energy efficiency. Ensure the supplier has a strong reputation for quality, innovation, and customer service to guarantee a successful and sustainable building project.

To compliment your high performing windows, Formance SIPs provide a high performance wall and roof solution and improves airtightness and drastically lowers thermal bridging. To see how SIPs could be used on your project, contact us on 0800 000 527 or email [email protected]
