Government studies have been carried out on many methods of insulation both internal and external.
These studies have shown that an exterior insulation system can radically improve the thermal insulation properties of your home by reducing heat loss with savings of up to 50% on fuel bills.
These studies have been reported by the Good Practice Guide no. 293, covering external insulation systems for walls of dwellings, and Good Practice Guide no. 389, covering external wall insulation of mobile homes in 1997. Good Practice Guide 293 and Case Study 389
In Summary they State;
EI (External Insulation) is often the best option for upgrading the thermal performance of existing buildings, and should be considered in refurbishment strategies.
EI can simplify construction and achieve environmentally significant thermal performance in new build projects.
Large amounts of insulation can be used with EI, while easily avoiding thermal bridging. The buildings’ structure will be protected and internal thermal mass can be achieved to moderate internal temperature fluctuations.
Comparison of cost for EI systems
Note: the costs shown are approximate.
Costs of external insulation are strongly
dependant upon location and height of project
(access costs), contract size, and
complexity of detailing. Good Practice Guide 293
In the Government’s comparison of; different wall insulation methods in refurbishment projects between; Insulated cavity walls, Internal lining and External insulation, the External insulation system came out by far the most efficient in; Upgraded appearance, potential for thermal improvement and structural improvement.
Our unique three layer insulation system exceeds building regulations for UV values and can reduce your heating costs by up to 50%.
External wall insulation has long been recognised within the building industry as the best method of achieving lower u values, better sound insulation and faster and more cost effective build times.
It can be applied to: Existing Brickwork
Rendered Facades
Concrete
Stonework
New Build Single skin block work
Concrete
Steel frame construction
Timber frame construction
With many advantages over traditional methods Thermally efficient it ensures consistent u-values
Avoids thermal bridging and achieves air tightness
Breathable and weatherproof
No loss of internal space
Faster construction process & reduces labour
Reduced foundation depths
Reduced or eliminated scaffolding time
Less disruption to occupants
Healthier living climate
Extends the building life
