One of the main benefits of doors with large areas of glazing is uninterrupted views outside. However, the additional weight of triple glazing can impact the maximum panel size possible – depending on the system. This is particularly relevant for products like bi-folding and sliding doors, and means instead of a few, wide panels, doors have to be specified with a higher number of glazed panels to avoid them being too heavy to operate individually. With more panels, comes more frames, meaning that the uninterrupted view people desire, as well as the amount of natural light, will be affected. The frame material will impact this. For example, aluminium’s strength allows it to bear more weight, allowing for larger panel sizes.
Looking ahead
As a specifier working on multiple projects per year, it’s also worth keeping abreast of the wider context of the triple- versus double-glazing debate. Last year, the Government updated Part L of the Building Regulations, which brought in more stringent thermal efficiency standards. For some manufacturers, this meant they had to
switch to triple-glazing as standard to meet the new regulations. However, the Future Homes Standard, which is being introduced in 2025, will take the Regulations even further, presenting a problem for those manufacturers already relying on triple glazing to meet the current standards. When specifying fenestration products, whether it’s for a renovation project, self-build, or new build, it’s wise to consider whether the suppliers that can deliver now will be able to do so in the future.
Clear conclusions It’s an interesting debate, and while triple glazing wins on the long-term benefits of reducing energy bills and noise pollution, homeowners looking to make a statement with large panes of glass, or who hope for a significant return on the investment in the short-term, won’t reap the benefits. This is where consultation with your client is essential to understand what their long- term goals are. If they are building their ‘forever’ home, then it makes sense to opt for triple glazing, which will eventually pay for itself.
