boast exceptional inherent strength, and provide superb building insulation
and aesthetic finishing in one simple step.
At a Glance:
• Reduces the need for secondary supporting framework
• Factory engineering and fire resistance up to 60 minutes give you security
• Improve the visual appeal of your building with a wide colour choice
• A complete weather-graded thickness range, from 50mm (U-value
of 0.39 W/m ² k) to 200mm (U-value of 0.10 W/m ² k) allows for any
construction purpose
• The products are ideal for modular and volumetric buildings, using
On or Off-Site construction
• Using these panels creates more workable space inside your
buildings, reducing multi-component wall build-ups
• Light in weight, these are labour and material saving products, which
give you at least 50% reduction in installation time
• Thermally superior tongue and groove joint provides greater fire
performance, excellent vapour resistance and best-in-class air tightness
• Available in bespoke lengths to fix horizontally or vertically directly to
steel frame centres
Applications include:
• External chillers and freezers

external facades and rainscreens
• Roofs – Support deck for secondary
components and follow on trades
• Lightweight thermal and structural support-panel for wall
and roof cladding materials
• Made to take external finishes such as zinc, copper, aluminium,
standing seams and rainscreens including weather membranes
• Minimise labour and install times with a reduction in
multi-component build ups
• Their low-air permeability reduces an overall buildings
CO ²
emissions
• Benefit from a superior, smooth backing surface over long
and bespoke panel lengths
• Thermally efficient range of thicknesses from 80mm (U value
of 0.25 W/m ² k) to 200mm (U-value of 0.10 W/m ² k)
• Up to 30 minutes fire resistance through LPCB certification

Hemsec SIPs
Hemsec SIPs are exceptionally strong, load-bearing panels for walls,
roofs and floors in commercial and residential buildings. They have
been extensively tested, and exceed the leading standards for
strength across the UK and Europe.
At a Glance:
• Far fewer building materials are required when you use SIPs,
saving significant time, labour and cost
• Gain far greater architectural flexibility than when you opt
for traditional building methods
• SIPs minimise heat loss through continuous, high
performance insulation
• They are made using OSB from sustainable FSC sources,
providing exceptional eco-benefits
• Under BBA, ETA and CE certification, a minimum life expectancy
of 60 years makes SIPs a safer bet than most building materials
available anywhere
• Fire resistance up to 90 minutes when utilised as the principal
structural element in built up wall systems
• Panel thicknesses range from 100mm (U-value of 0.34 W/m ² k)
to 225mm (U-value of 0.14 W/m ² k)
Applications include:
• Affordable housing – thermal
properties make them inexpensive
to run
• Luxury housing – flexibility of design
gives architectural creative freedom
• Public Buildings including education
and healthcare
• Commercial buildings –
cost-effective to build and manage
• Industrial buildings – large spans
combined with load-bearing strength

bonded during the manufacturing process to the wet lay
down polyisocyanurate closed cell insulation core.
Panels are available with an array of different colour and
steel finishes from various suppliers to meet all project
requirements and are completed with our Smooth, Microrib
or 100 Rib detail facing options.
The cover width is 1155mm, with panel thicknesses ranging
from 50mm to 200mm. Made-to-order in bespoke lengths
from a minimum of 2m (2.4m on 50mm panels) up to our
maximum line capability of 15m.
Timber faced
Hemsec SIPs are constructed from two faces of Oriented
Strand Board (OSB/3) sandwiching a pressure injected,
rigid polyurethane (PUR) insulation core.
We can supply panels with either 15mm or 11mm thick
OSB facings.
The cover width is 1200mm, with panel thicknesses ranging
