SIP construction standards

Existing violations and technological errors that occur when building houses with SIP technology

Consequences of violating the technology

Intermediate floors (level +0.000) and (level +2.800)

Reinforced SIP panels 224 mm thick.
(OSB3 – 12 mm, EPS foam – 200 mm, OSB3 – 12 mm)
(embedded timber spacing 200x100 – 625 mm)

SIP panels 174 mm thick may be installed.
(OSB3 – 12 mm, EPS foam – 150 mm, OSB3 – 12 mm)
(embedded timber spacing 147x74 – 625 mm). For a span of no more than 3 m.

Beam floor.

Installing unreinforced panels with an embedded timber spacing of 1250 mm.

Installing panels with OSB3 thinner than 12 mm

Using floor panels thinner than 174 mm

Sagging of the ceiling in the middle of the panels during use.

Reduced floor rigidity, which can lead to collapse of the structure during use

Reduction of the permissible load per 1 m2

Exterior walls

HOUSE walls use SIP panels 174 mm thick.
(OSB3 – 12 mm, EPS foam – 150 mm, OSB3 – 12 mm)

DACHA (summer house) walls use SIP panels 124 mm thick.
(OSB3 – 12 mm, EPS foam – 100 mm, OSB3 – 12 mm)

Embedded timber: glulam with a cross-section of at least 74x147 mm.

Standard ceiling height is 2,8 m and 2,5 m.

Installing panels with OSB3 thinner than 12 mm

Using boards with a cross-section smaller than 74x150 mm as embedded timber

Reduced wall rigidity, which can lead to collapse of the structure during use

Reduction of the permissible load per 1 m2

Roofing

Reinforced SIP panels 224 mm thick.
(OSB3 – 12 mm, EPS foam – 200 mm, OSB3 – 12 mm)
(embedded timber spacing 200x100 – 625 mm)

SIP panels 174 mm thick may be installed.
(OSB3 – 12 mm, EPS foam – 150 mm, OSB3 – 12 mm)
(embedded timber spacing 147x74 – 625 mm).
For a span of no more than 3 m.

Cold rafter system

Installing unreinforced panels with an embedded timber spacing of 1250 mm.

Installing panels with OSB3 thinner than 12 mm

Using floor panels thinner than 174 mm

Sagging of the ceiling in the middle of the panels during use.

Reduced floor rigidity, which can lead to collapse of the structure during use

Reduction of the permissible load per 1 m2

Material requirements

Use of OSB-3 from European and Russian manufacturers for exterior SIP panels

Use of Canadian OSB-3 for exterior SIP panels

Lower moisture absorption values.

Use of EPS foam, grade PPS-14

Use of EPS foam, grades PPS-13, PPS-12

Reduced load-bearing capacity of the SIP panels.

Use of dry, planed timber treated with a fire and bio-protective compound

Use of unplaned, green or “semi-dried” timber

Formation of fungus,
Damage to the structure of walls and floors

Use of special Spax screws to ensure the required rigidity of the structure

Use of nails or lag screws (threaded self-tapping screws)

Reduced rigidity of the structure, which can lead to deformation and collapse of the house.
