Kingspan Insulation LTD
1892 The Vacuum Flask is invented by Sir James Dewar
1930 The first Vacuum Insulation Panel (VIP) emerges
1970s The first commercial applications for VIPs
1999 US Department of Housing and Urban Development evaluated
the market potential for VIPs in residential buildings
2005 Low-energy building in Munich is the first building in the world
more than two storeys high to feature VIPs in the facade
2012 Kingspan Insulation launches Optim-R
Timeline of events
Thermal Conductivity 0.007 W/m.k (aged design value)
Core
Optimum performance rigid vacuum insulation panel with a microporpous core which is evacuated encased and sealed in a thin, gas-tight envelope
Standard Product Width (mm) 300 – 600*
Standard Product Length (mm) 300 – 1200*
Product Thickness (mm) 20 - 60

Comparative Thicknesses

130 mm
* R-value of 6.000 m2.K/W
220 mm
Flooring Applications:
Solid concrete based floors
Beam and dense block ground floors
Considerations:
Floor to ceiling height
Thick insulation may mean ground floor door lintels, radiators and skirting boards all need to be raised.
Saves installing a replacement concrete floor (and time associated eg. drying etc.)
Edwardian house example:
Solid concrete based floor (perimeter / area = 0.3)
Just 20mm of a VIP product with a λ (thermal conductivity) of 0.007 would achieve U value of 0.20 W/m2.K
You would need 95mm of EPS to achieve the same U-value

Applications: Solid and cavity brick wall Solid blockwork Variety of finishes:
• Render • Tiles • Brick slips
Considerations Space around the exterior of the building – tight space on a site
Less remedial work to the outer skin of the building. Eg. eaves may need extending if insulation is too thick.
Thicker insulation would reduce the amount of daylight coming into the building
External Wall Insulation
Applications: Green roof covering –
Dense Concrete Deck with Suspended Ceiling
Metal / Concrete Deck Roof with No Ceiling
Concrete / Dense Concrete / Timber Deck
Considerations Planning restrictions Sleek design Maintain and even transition
between indoor and outdoor levels
