Introduction  Alumasc external wall 
insulation systems totally 
encapsulate the building structure, 
which is the most effective way of 
insulating a building, with least risk 
of cold bridging and interstitial 
condensation.

Swistherm 00/3766
Swisslab 93/2914
Swisspan 97/3410
M.R. S5 93/2920
M.R. S6 88/2090

2004 Environmental Standard and 
complies with BS EN ISO 9001: 2008 
Quality Management system.
DESCRIPTION
New build systems
  Swistherm is 
a thin-coat solid wall insulation 
system. Insulation slabs are 
mechanically and adhesively fixed 
direct to a continuous substrate and 
are then faced with silicone or 
mineral renders. Natural cork 
insulation, when used with the 
system, provides a low carbon, 
energy efficient solution.
Swisrail is a thin-coat insulated 
render system specifically designed 
for use on framed buildings subject 
to NHBC approval. The system 
incorporates a series of steel rails 
and channels to provide a 25 mm 
drained cavity between the 
insulation. Available with a choice of 
insulation and silicone or mineral 
render finishes.
Refurbishment systems  Swisslab 
is one of the market-leading solid 
wall insulation systems for 
overcladding existing properties. 
Extensively used to upgrade social 
housing, Swisslab strongly 
contributes to urban regeneration. 
Insulation materials are 
mechanically fixed direct to a 
continuous substrate and are faced 
with M.R. Polymer modified renders 
for a traditional appearance, or 
silicone or mineral renders for a 
contemporary look.
Swisspan is used to overclad 
existing properties where 
possibilities for mechanical fixing 
are restricted to structural elements.  
Swisspan is typically used on 
structural frames with 
non-loadbearing steel or concrete 
infill panels and non-traditional 
house types such as Airey Duo 
Slab, BISF, Cornish, Crudens and 
Unity. Insulation is mechanically 
fixed to a galvanized steel horizontal 
support rail system that spans

range of silicone, mineral and polymer-modified decorative render finishes.

between structural columns. 
A choice of render finishes is 
available.
Insulation options
(Varies depending on Alumasc 
system selected):
Cork: the ecological choice for 
sustainability and recyclability.
Phenolic: maximum thermal 
performance, minimum thickness.
PIR (Polyisocyanurate): highly 
durable alternative to phenolic.
Mineral wool: where a 
non-combustible façade is required.
Expanded polystyrene: for economy
Extruded polystyrene: for below 
DPC applications.
Render finishes
ST Silicone Renders
 are high 
performance, through-coloured 
renders available in a wide range of 
colours and textures.
ST Mineral Renders is a natural, 
textured white range that can be 
over-painted with Alumasc silicone 
façade paint.
M.R. S7 and S5 Dashing Render 
are one-coat polymer cement 
dashing renders available in seven 
standard colours for use with a 
choice of aggregate dash finishes.
M.R. S4 Plain Render is a 
one-coat, polymer modified system, 
ideal for large elevations and feature 
bands. Available in seven standard 
colours which are overpainted with 
M.R. S6 masonry paint.  Can also 
be top coated with Silkolitt silicone 
render.
M.R. Rendabrick
 is a three-coat, 
simulated brick effect render used to 
match existing brickwork or create 
new effects and details. Choice of 
two mortar and two brick colours.
Brick slips
Alumasc traditional brick slips 
offer an easy to apply, high impact 
performance finish where the use of 
real bricks would not be viable. 
Alumasc acrylic brick slips are a 
lightweight alternative, suitable for 
high rise applications.
Decorative coatings
M.R. S6 masonry paint
 is a 
polymer-based coating available in 
18 standard colours.
Silicone façade paint is a high 
specification paint with water 
repellent and self-cleansing 
properties with 400 colour options
