Perimeter Plus™ (for insulating new timber frame walls)
Description
Knauf Insulation Perimeter Plus™ is an
unbonded, virgin glass wool blowing insulation with high thermal
resistance characteristics for timber frame construction.
Blow-in-Blanket® System (BIBS) is a patented
process consisting of glass mineral wool loose fill blown in behind
a special netting material for timber frame construction. Perimeter
Plus™ Blowing Insulation is used in both new and existing
structures as a Blow-In-Blanket System for closed cavity
applications in which ventilation is not required.

Performance
Thermal
- Perimeter Plus™ has a range of thermal
conductivities between 0.033 - 0.042W/mK depending on the density
required in the application.
Fire
- Perimeter Plus™ is classified as Euroclass A1
to EN ISO 13501-1
Acoustic performance
- Perimeter Plus™ has excellent sound
absorption characteristics.
Benefits
- Ultra high energy saving
- Quick and clean to
install
- Made using recycled glass
bottles
- Installed from inside the
house
- Fills all voids
- Non-combustible
- High sound absorption
Features and Benefits
Excellent thermal properties, fills all gaps
and voids, creating a thermal barrier against outside air thereby
improving temperature control.
Environmental
Perimeter Plus™ conserves energy and therefore
assists in reducing demand for fuels for the heating and
air-conditioning of buildings. As a result, they reduce the
emissions of the major greenhouse gas, CO2. The energy
and CO2 emissions saved by the products in use vastly
outweigh those generated in their manufacture. Perimeter
Plus™ has a low impact on the environment and is classified as Zero
ODP and Zero GWP.
Thermal performance
- The stated thermal conductivity is provided
by installing in accordance with the manufacturer’s
instructions.
Vapour resistance –
resistivity
- Perimeter Plus™ offers negligible resistance
to the passage of water vapour and hasa vapour resistivity of 7.00
MN.s/g.m.
Noise reduction
- Improves sound insulation performance of
construction element into which it is installed.
Non-corrosive
- Will not accelerate the corrosion of
aluminum, steel or copper.
Resists microbial growth
- Does not promote the growth of fungi or
bacteria and will not rot or sustain vermin, rodents or
insects.
Poly bag packaging
- Excellent protection from on site dust and
moisture, unitised packaging eases movement in the warehouse and
reduces storage space.
Speed of installation
- Saves installation time by minimising the
steps needed to fully insulate tight corners and hard to reach
areas
