Wood:UpHigh results

These resistance to fire tests is available to use for inspiration and documentation. There will continuously be published new reports until the end of the project. There will not be published classifications reports, but only test reports. Test reports conducted through the Wood:UpHigh project will be redacted to leave product names, since the project cannot create competitive advantages.

Prøvningsrapportens resultater omhandler kun konstruktions brandmodstandsevne, f.eks. hvor lang tid Bæreevne (R), Integritet (E) og isoleringsevne (I) er overholdt. Den siger ikke noget om anvendelsesområde eller de indgående materialers reaktion på brandegenskaber. Temperaturmålinger mellem pladelag/indvendig i konstruktionen kan bruges til at vurdere brandbeskyttelsesevne af f.eks. isoleringen (F.eks. K1-10), dog kan målinger ikke sidestilles med klassifikation.

Anvendes rapporten til at opfylde et præaccepteret krav som f.eks. EI60 – A2-s1,d0, bør man være opmærksom på at der er en afvigelse i forhold til reaktion på brand kravet samt beklædningskravet. Rapporten kan dog stadig anvendes i brandklasse 3 og 4 hvis der kan laves en eftervisning af denne afvigelse efter principperne i ”Vejledning til kapitel 5 – Brand” - Kapitel 8 - Eftervisning.

Test 0: Exterior wall with blown-in wood fiber insulation

The construction of the test specimen:

Exposed side:

1. 12 mm chipboard

2. 18 x 46 mm pine wood studs/spacers

3. 22 mm wood fibre board

4. 45 x 295 mm C24 dry graded

construction timber with 295 mm wood fiber insulation blown in

5. 22 mm OSB3 board

6. 2 x 12.5 mm gypsum fibre boards 

The fire test was used in a specific project to show the performance in an outside scenario. Although the test was conducted prior to Wood:UpHigh, its results have been incorporated into the example catalogue.

Target: REI60
Run time: 96 minutes

Test: 1 Floor deck with visible beams and blown paper wool insulation

The construction of the test specimen:

Exposed side:

1. 60 mm CLT-element

2. Blown paper wool insulation

3. 120 x 240 loadbearing beams

4. 60 x 60 timber battens

5. 15- and 18-mm gypsum fibre boards

The first test construction was used for the specific project “MiniCO2 Etagehus TRÆ”, and the focus was a construction with high acoustic requirements and visible beams.

Target: REI60
Run time: 110 minutes

Test 2: Exterior wall with blown-in wood fiber insulation

The construction of the test specimen:

Exposed side:

1. 12.5 mm gypsum fibre board

2. 15 mm chip board

3. 45 x 295 mm dry graded C24

construction spruce wood with 295 mm wood fiber insulation blown in

4. 22 mm wood fibre board

5. 18 x 46 mm pine wood batten/spacers

The fire test drew inspiration from Test 0, but it approached the examination from a different angle by analysing/testing the wall from the opposite side. This alternate perspective aimed to establish a worst-case scenario.

Target: REI60
Run time: 71 minutes

Test 3: Floor deck with clay covering

The construction of the test specimen:

Exposed side:

1. 3 mm clay plaster

2. 2x10 mm clay board

3. 15 mm chip boards

4. 45x195 mm construction spruce wood, with 95 mm blown in wood fiber insulation.

5. 15 mm chipboard

The fire test was conducted using a distinct project approach, in which the conventional gypsum material was substituted with two clay boards. This substitution diverged from the traditional K2 60 covering solution.

Target: REI60
Run time: 47 minutes

Test 4: Prefabricated fire separating wall with straw insulation

The construction of the test specimen:

Exposed side:

1. 2x12.5 gypsum fibre boards

2. 22 mm wood fibre board

3. 44x93 mm wooden studs with 5 standard straw element insulation

4. Felt membrane

5. wood spacers

The test was centered around straw insulation, as per the advisory group's request, primarily due to the material's potential for local production.

Target: REI60
Run time: 113 minutes

Test 5: Symmetric fire separating wall with grass insulation

The construction of the test specimen:

Exposed side:

1. 12.5 mm gypsum fibre board

2. 15 mm chipboard

3. 45x95 mm construction spruce wood with 2x100 mm grass fiber insulation

4. 15 mm chipboard

5. 12.5 mm gypsum fibre board

The test focused on grass insulation, prompted by our preliminary small-scale tests that revealed significant material shrinkage upon exposure to fire.

Target: EI60
Run time: 64 minutes

Test 6: Symmetric fire separating wall with seaweed wool

The construction of the test specimen:

Exposed side:

1. 10 mm clay board

2. 22 mm clay board

3. 45x95 mm construction spruce wood with 4 layers of seaweed wool

4. 22 mm clay board

5. 10 mm clay board

This test draws inspiration from test 5, with the objective of delving into the behaviour of clay board as covering.

Target: EI60
Run time: 66 minutes
