Technical Information

Product Performance

Available lengths

Standard lengths 2m to 6.5m.

Available Widths

Widths from 200mm to 1200mm maximum.

Materials

External or Internal faces can be of the following combinations the standard product is OSB on both faces:

OSB (Oriented Strand Board)

OSB Grade 3 BBA Approved board manufactured to BS EN 300: 1997 For OSB /3, Load bearing oriented strand boards for use in humid conditions.

Standard external and internal sheet thickness 15mm.

Alternative facing available on request.

Insulation Core

Polyurethane (PUR): CFC & HCFC free, Closed Cell insulation core with a Zero Ozone Depletion Potential (ODP).

Panel Joint

Standard spline joint achieves low air leakage and thermal performance.

Air Leakage

Overall air leakage for complete enveloe less than 5m3//hr/m2 at 50Pa.

Thermal Insulation

Calculated using the method required by the Building Regulations Part L2 (England & Wales) and Building Standards Part J (Scotland).(Vertical Spline J)

Above based on an aged thermal conductivity of 0.026 W/m K for the insulation core tested to BS EN 13165:2001.

Fire

The panels have passed the requirements of BS476 Part 21fire resistance of load bearing walls and has achieve up to75 minutes fire rating. (See Separate specification)

Acoustics

Internal Walls

OSB Faced Panel plus 12.5mm plasterboard and 12.5mm fireboard to each face achieved a weighted sound reduction index (SRI) 49dB (DnT,w+C;Ctr). (This construction will achieve a FR - 60 minutes fire rating).

Party Walls (Single Panel)

OSB Faced Panel plus one face with 12.5mm Sound Block and one face with 12.5mm Plaster board, achieved a weighted sound reduction index (SRI) 49 db. (This construction will achieve a 60 minutes fire rating).

The Key benefits for using SIPS

• Highly energy efficient. Life Cycle Assessment.
• BBA Certified product.
• “A” Rating in BRE Green Guide to Specification.
• Dry construction / no wet trades.
• Not weather dependant.
• Ideal substrate for internal/external finishes.
• Lightweight construction dictates reduced foundation requirements.
• Roof and wall structural performance dictates reduced frame sizes.
• Air tight construction as low as 0.95 air changes per hour at 50 Pa. (this is approx.1m3/hour/m2 at 50Pa)
• Fast track installation results in reduced construction periods.
• No requirement for netting to install roof panels thus reducing potential for
