About the Product

The ThermaSAVE® Structural Insulated Panels (SIPs) consist of a
high-density expanded polystyrene core material bonded to, and
acting integrally with, relatively thin, high-strength facing materials
consisting of cellulose based fiber cement boards. When used as a
wall, roof, or floor system in housing and multi-storey building
applications, the SIPs provide exceptional strength for the amount
of material used and superior insulation and acoustical properties.
In combination the ThermaSAVE panels provide the best of both
worlds while having numerous advantages over standard building
materials.

length (or height) of adjacent panels, parallel to, and at both faces. At panel joints, the splines are
shared by adjacent panels, with each panel edge connected by screws to half of the spline. Panels
are manufactured with the expanded polystyrene (EPS) foam core pre-cut to accommodate the
thickness of the spline at its edges. Splines are typically of the same thickness as the panel skins
where they are attach to. The thickness of the panels is determined prior to construction (preferably
during design stage) in accordance with the loading, insulation and aesthetic requirements.
Adhesives are not required during construction while special elastomeric sealants and bonding
agents are applied at the joints and inter-connections with structure members, consistent with good
workmanship. Any sealants or bonding agents used are compatible with the materials to which they
are applied. Panels are aligned properly, are level and plumb, sealed and fastened within specified
tolerances. The panels are then fastened through the skins into the interconnecting splines. It is not
necessary that the splines be single pieces along the full length or height of the panels. It is
acceptable with longer panels to use two or more splines to complete the length required, though as
a rule, the longer the individual splines the better.

FLOOR PANELS

Manufactured with fiber cement board facings or oriented strand boards bonded on both sides of the
polystyrene core. The floor panels can be of various thicknesses governed by strength serviceability
requirements and acoustical needs. Spans of up to 12 feet without supports are available.
ThermaSAVE® floors are not "springy" nor do they "squeek". Floor panels are excellent
soundproofing between floors, in apartment buildings for example. When panels are installed, the
floor is ready for floor coverings.

WALL PANELS

It can accommodate various interior and exterior finishes in conjunction with the main SIP wall. An
exterior finish can be T1-11, metal or aluminum, brick or masonry tiles, aggregate wash-out, plain
concrete texture, stucco and different wood finishes such as cedar or split log. The ThermaSAVE®
offer excellent insulation and acoustical properties. It is great for common walls or partywalls,
partition walls fire walls and cladding.

ROOF PANELS

This is excellent for cathedral ceilings and high ceilings. Roof panels will span 12 feet without
support. Typically a ridge beam is needed at the center with panels resting on beam and exterior
walls. With a free span of 12 feet, a building could be designed with 24 feet width space. If more
width space is required, intermediate beams will have to be provided or partition walls can act as
supports at intermediate locations to accommodate wall span requirements. Roofing panels can be
manufactured with varying thickness. The thicker the panel, the more savings on heating or cooling
is achieved. The roof panel is the most versatile on the market. When panels are in place, they can
be used as the roofing material itself. It can be painted in line with the owner requirements or can be
applied on with additional aesthetic features such as wood shakes, sheathing, or plastic roofing.

PANEL OPENINGS

Window and door openings in walls are typically pre-cut at the plant prior to delivery to construction
site in accordance to the design drawings. Panel openings are prepared by cutting through the full
thickness of the panel. With the panel section removed, the EPS is recessed from the cut opening
to accept a dimensional lumber wrap or C-channels. 2X lumber material is typical of sills and jambs,
4X or larger lumber material may be required at the header depending on the width and location of
the opening. The dimensional lumber faces align with cut panel skins. In the absence of lumber,
galvanized steel C-channels can be used corresponding to dimensional lumber specifications. It is
acceptable for an opening to span through a spline connection though it should not begin or end
within six inches of a panel joint with a spline connection. An opening may exist immediately next to
a post within the wall with the jamb nailed directly to the post, providing the header is properly
supported.
