Window specification: Why expert advice is key

Suppliers that offer design, sustainability, cost planning and BIM services can help architects maximise the performance and energy efficiency of the products they choose

In association with
Velfac cost consultancy and sub-contracted design services help provide early budget certainty and a streamlined design process.

From meeting sustainability targets to enabling design innovation, modern windows and doors play a vital role in creating energy efficient, well ventilated buildings filled with natural light, while setting new standards in thermal and acoustic insulation, durability and security.

Expert specification is required, however, to fully maximise their potential and to ensure full compliance with often complex building regulations, especially if curtain walling or cladding is part of the design.

Window suppliers can often provide this specification expertise. At Velfac, services such as cost consultancy and sub-contracted design, for example, help provide early budget certainty and streamline the design process.

Performance calculators are useful in first stage specification planning, while acoustic modelling can ensure the precise placement of double and triple glazing within a facade, resulting in optimal (and more cost-effective) noise control.

Suppliers should also have calculation tools for U-values and unit weight and be able to supply up-to-date test data ready for review, as required to satisfy building regulations. To meet sustainability targets, also ask for unit-specific U-values and ‘cradle to grave’ manufacturing analyses, as well as ventilation strategies designed to ensure an ideal indoor climate all year round.
