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

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
