Signed, sealed and delivered? It can be. Construction professionals often refer to a ‘building’ envelope when talking about property, amongst plenty of other jargon as well! What does ‘Building Envelope’ mean? We turn super sleuth and investigate on your behalf…
A building envelope is a seal around a building – but not quite in the same way as a letter would fit into a postal envelope.
Be it your house, a commercial property, or a standalone building, the building envelope refers to the seal between the interior of the rooms, and your home’s exterior.
In a property, a building envelope isn’t about the bricks and mortar on the outside, but rather everything that goes between those outside bricks, and the rooms indoors.
A building envelope includes insulation, windows, roofs, doors, and fenestrations. To be frank, it’s more the bubble wrap around goods in a jiffy bag than it is a letter in an envelope!
What is a Building Envelope for?
A building envelope has three main functions – entry and exit, ventilation, and insulation.
The entry and exit refers to the doors, without which the building would be completely inaccessible, and the ventilation to a healthy degree of air flow through the property. Insulation is then the final seal.
It’s important to have an efficient and total insulation seal for a variety of reasons.
The most well-known is, of course, heat, but proper insulation should also maintain an ambient temperature throughout the year, keeping cool in the Summer , and wonderfully warm in the Winter.
