Improving Building Envelope Performance With Continuous Insulation
In order for a building to be considered high performance, it must meet various regulations and standards linked to energy efficiency and sustainability, whilst minimising environmental impact.
However, to meet these aims, there must be certain systems in place to work towards continuous insulation, and therefore optimal performance, because without effective solutions, energy efficiency is compromised due to heat loss through thermal bridging.
What a continuous insulation system is
A continuous insulation system is a series of insulating elements that are implemented in a building’s design and structure to reduce heat loss. Some examples include, thermal cladding, cavity wall insulation and concrete foundations.
However in order for these systems to be considered as continuous insulation, they must also be installed with thermal break solutions. Due to how they’re fixed in place, the bolts break the continuous insulation of the project and these areas must be isolated with thermal breaks to reinforce the insulation, and therefore combat thermal bridging.
Why continuous insulation is used in building design
Continuous insulation is used in the design of buildings in order to improve the energy efficiency of the structure once constructed. It provides the building with an additional layer of protection from heat loss, albeit not preventative, but it does limit the amount lost.
Implementing a continuous insulation system is crucial to building design especially in today’s industry where there are strict targets to be met.
Continuous insulation requirements and regulations
New construction projects must meet certain building codes including the International Energy Conservation Code (IECC). This dictates that buildings must comply with meeting a high R-value so that it is considered at an optimal thermal performance and energy-efficient.
Therefore, it is essential that new buildings are designed with continuous insulation solutions in place so that they meet this.
How continuous insulation reduces thermal bridging
Continuous insulation systems can be installed to help reduce heat loss in buildings as it can restrict the movement of energy. Even though implementing these solutions is effective in reducing heat loss, they can be even more effective in minimizing thermal bridging when installed with thermal break solutions.
This is because when the insulation is fixated in place the attachments tend to break the continuous layer and allow thermal bridging to occur.
Frequently Asked Questions
A continuous insulation system is a series of insulating elements that are implemented in a building’s design and structure to reduce heat loss.
For something to be considered as continuous insulation, the material must improve the thermal performance of a building by meeting a high R-value and be code compliant.
Heat transfers through conductive materials and by combatting this with non-conductive insulation, it minimizes the movement of energy. Adding continuous insulation solutions like cladding or cavity wall insulation are ideal to reduce heat loss, but are more effective when installed with thermal break solutions.
