1. MODULE #1: PRODUCT KNOWLEDGE LIBRARY.

 

1.a. SOUND BARRIER (0:14)

 

WHAT UNIQUE ATTRIBUTE IN WOOD FIBER MATERIALS ALLOWS IT TO EXHIBIT SUCH EXTRAORDINARY INSULATING PROPERTIES?

 

SHORT ANSWER: 

WOOD FIBER IS HOLLOW INSIDE.

 

EXTENDED ANSWER: 

AIR PORES MAKE THE BEST INSULATORS SINCE THE AIR IS IN A STATIONARY STATE THAT CANNOT CONDUCT TEMPERATURE AND SOUND VERY WELL. 

AN EXAMPLE WOULD BE AIR SEALED BETWEEN TWO WINDOW PANES. THE MORE AIR POCKETS AND PORES IN A MATERIAL, THE BETTER IT INSULATES. 

WOOD FIBER IS HOLLOW INSIDE. 

THEREFORE, IN A FIBERBOARD, THE AIR IS NOT ONLY CONTAINED BETWEEN THE FIBERS, BUT ALSO INSIDE THEM.

 

WHAT, OTHER THAN AIR CHAMBERS, CONTRIBUTES TO THE SOUND INSULATION OF THIS MATERIAL?

 

SHORT ANSWER: 

THE FIBER CONTENT OF THE MATERIAL.

 

EXTENDED ANSWER: 

FIBROUS MATERIALS ARE VERY GOOD AT DAMPENING ANY WAVE, INCLUDING SOUND WAVES. 

DUE TO THE FIBER’S LENGTH, SURFACE AREA, AND ROUGHNESS, THE SOUND IS EXTINGUISHED. 

FOR EXAMPLE, IF YOU TAKE A LONG ROPE CONSISTING OF MANY THIN FIBERS AND SWING A WAVE ALONG IT, THEN, AT THE BEGINNING OF THE ROPE, THE AMPLITUDE WILL BE LARGE AND, AT THE END, IT WILL FADE AWAY. 

THEREFORE, CARPETS OR FELT PRODUCTS PROVIDE SOUND INSULATION AND PREVENT COOLING. WOOD FIBER PRODUCTS HAVE ENORMOUS FIBER CONTENT AND AIR POROSITY.

 

1.b. SOUND INSULATION IN WALLS AND CEILINGS (3:17) 

 

WHICH BUILDING MATERIAL, WHEN COMBINED WITH STEIO WOOD UNDERLAYMENT, YIELDS THE BEST SOUND INSULATING RESULTS?

 

SHORT ANSWER: 

DRYWALL.

 

EXTENDED ANSWER: 

THERE IS AN IMPORTANT CONDITION FOR CREATING GOOD SOUND INSULATION ON A BUILDING’S PREMISES: THE USE OF LAYERS OF DIFFERENT DENSITY AND MASS IN THE STRUCTURE.

THESE INCLUDE HARD AND HEAVY (SOUND-REFLECTING) LAYERS AND SOFT AND FIBROUS (SOUND-ABSORBING) LAYERS. 

THE COMBINATION OF DRYWALL AND WOOD FIBER LAYERS MAKES FOR THE IDEAL SOUNDPROOFING CONSTRUCTION. 

AS SOUND PASSES THROUGH THE LAYERS, IT IS REFLECTED AND ABSORBED MANY TIMES. AN IMPORTANT RULE IS THAT ONE LAYER OF DRYWALL AND A LAYER OF WOOD FIBER WILL SOUND BETTER THAN TWO LAYERS OF DRYWALL OR TWO LAYERS OF WOOD FIBER.

THERE MUST BE A COMBINATION OF SOUND REFLECTION AND SOUND ABSORPTION!

 

WHY IS IT PREFERABLE TO ADHERE STEICO WOOD UNDERLAYMENT TO WALLS USING GLUE, RATHER THAN NAILS OR SCREWS?

 

SHORT ANSWER: 

IT PROVIDES BETTER SOUNDPROOFING.

 

EXTENDED ANSWER: 

A NAIL OR SELF-TAPPING SCREW THAT PASSES THROUGH STEICO WOOD UNDERLAYMENT AND IS FIXED IN THE STRUCTURE’S FRAME IS A SOUND BRIDGE THROUGH WHICH SOUND IS TRANSMITTED. 

THE MORE BRIDGES THERE ARE, THE LESS EFFECTIVE THE SOUND INSULATION IS. 

THEREFORE, THE USE OF GLUE IS PREFERABLE.

 

1.c. VAPOR PERMEABILITY (4:23) 

 

WHAT ARE THE CONSEQUENCES OF MOISTURE ACCUMULATION IN A HOUSE STRUCTURE?

 

SHORT ANSWER: 

DAMPNESS, MOLD, MUSTY ODOR, FUNGUS, DESTRUCTION OF STRUCTURES AND FINISHES, LOSS OF INSULATING PROPERTIES.

 

EXTENDED ANSWER: 

MOISTURE IN THE STRUCTURES OF WALLS, FLOORS, AND INTER-FLOOR FRAMEWORKS APPEARS EITHER AS A RESULT OF INCOMPLETE DRYING DURING CONSTRUCTION, FLOODING AND LEAKS, OR CONDENSATION—THE RESULT OF WARM AIR FROM THE HOUSE AND COLD OUTSIDE AIR (LIKE WARM VAPOR WHEN BREATHING ON A COLD MIRROR). 

MOISTURE ACCUMULATING BETWEEN THE FIBERS OF THE INSULATION WILL LEAD IT TO SINK AND LOSE ITS INSULATING PROPERTIES. AS AN EXAMPLE, WE FEEL MUCH COOLER IN WET CLOTHES THAN IN DRY ONES.

IF THE MOISTURE IS NOT PERMANENTLY DRIED OUT, IT WILL ACCUMULATE AND CREATE OPTIMAL

CONDITIONS FOR THE GROWTH OF MOLD, MUSTY ODORS, FUNGUS, AND THE DESTRUCTION OF THE HOUSE’S STRUCTURES AND FINISHES. 

AS AN EXAMPLE, HOT BREAD IN A PAPER BAG WILL RETAIN ITS CRUNCH AND SHAPE FOR A LONG TIME, AND IN AN AIRTIGHT PLASTIC BAG, IT WILL QUICKLY GET WET, LOSE ITS SHAPE AND AIRINESS AND WILL DETERIORATE IF THE BAG IS NOT OPENED TO RELEASE STEAM.

 

HOW TO GET RID OF EXCESS HUMIDITY IN A HOUSE STRUCTURE?

 

SHORT ANSWER: 

THROUGH OPEN PORES AND BY ABSORPTION INTO THE FIBERS.

 

EXTENDED ANSWER: 

A HYDRO-VAPOR BARRIER IN THE HOUSE WILL PROTECT FINISHING MATERIALS, SUCH AS A WOODEN FLOOR, FROM CONTACT WITH MOISTURE AND DESTRUCTION. 

BUT THE MOISTURE WILL BE UNDER THE FILM FOR A LONG TIME. 

FIBROUS MATERIALS WITH THE NORMAL HUMIDITY OF LOAD-BEARING STRUCTURES PARTIALLY ABSORB MOISTURE UP TO 20% OF THEIR WEIGHT EVEN WITHOUT A VAPOR BARRIER AND PARTIALLY REMOVE IT THROUGH THEIR OPEN PORES AND CAPILLARIES.

MOREOVER, THE WOOD FIBER PASSES THROUGH THE DIFFUSION OF STEAM AND DRIES UP MANY TIMES WITHOUT LOSING ITS PROPERTIES. 

FOR EXAMPLE, HOUSES MADE OF TIMBER DO NOT HAVE INSULATION IN THE WALLS, BUT AT THE SAME TIME THEY ARE WARM AND DRY—THE HOUSE’S WALLS "BREATHE" FOR DECADES. 

THIS IS “VAPOR OPEN.”

 

1.d. WATER RESISTANCE (5:25) 

 

WHAT ATTRIBUTES OF THE WOOD FIBER MATERIAL ENABLES IT TO REDUCE AIR HUMIDITY AND DRYNESS IN THE ROOM WHERE IT IS INSTALLED?

 

SHORT ANSWER: 

BY ABSORBING MOISTURE FROM THE AIR WHEN IT IS ELEVATED AND THEN RELEASING MOISTURE WHEN THE AIR IS DRY.

 

EXTENDED ANSWER: 

IT IS THE HOLLOWNESS OF THE WOOD FIBER THAT ENSURES THE ABSORPTION OF MOISTURE FROM THE AIR AND ITS SUBSEQUENT RELEASE INTO THE AIR AGAIN. 

THE USE OF WOOD FIBER UNDERLAYMENT WILL PROTECT THE LOWER FLOORS FROM FLOODING IN CASE OF SMALL LEAKS—THE UNDERLAYMENT WILL SOAK UP ANY INCOMING WATER LIKE A TOWEL. 

AND JUST LIKE A TOWEL, AFTER DRYING, THE UNDERLAYMENT WILL RETAIN ALL ITS PROPERTIES.

 

WHAT SHOULD BE DONE IF THE UNDERLAYMENT AND THE FINISHED FLOOR GET WET DUE TO PIPE BREAKAGE OR ANY OTHER HOUSEHOLD WATER LEAK?

 

SHORT ANSWER: 

DRY THE FLOOR AND UNDERLAYMENT.

 

EXTENDED ANSWER: 

WHEN DISASSEMBLING THE FLOOR STRUCTURE IN DIFFERENT PLACES (IT IS NOT POSSIBLE TO DISASSEMBLE THE WHOLE ROOM AT ONCE, AS YOU HAVE TO PROVIDE PATHWAYS FOR PEOPLE TO WALK AND A PLACE TO STORE THINGS), ALLOW MOISTURE TO EVAPORATE. 

AFTER THE UNDERLAYMENT IS COMPLETELY DRY, REASSEMBLE THE FLOOR AND ARRANGE THE FURNITURE.

 

1.e. PROTECTION OF THE "CLICK-LOCK" FLOORING SYSTEM (6:53)  

 

WHAT CAUSES SQUEAKING OF FLOORS?

 

SHORT ANSWER: 

WHEN THE FINISH FLOOR DOES NOT HAVE RIGID SUPPORT UNDER IT.

 

EXTENDED ANSWER: 

IN CASES WHERE THE FINISH FLOOR DOES NOT LIE WITH ITS ENTIRE SURFACE ON A RIGID BASE, THE FLOOR CAN SHIFT AND SPRING WHEN SOMEONE WALKS ON IT. 

AT THIS POINT, THE CONNECTING ELEMENTS MAY SQUEAK AND MAY EVEN SUBSEQUENTLY BREAK. 

THE MAIN CAUSES ARE INCORRECTLY SELECTED THICKNESS AND SOFTNESS OF THE UNDERLAYMENT AND THE ABSENCE OF GAPS BETWEEN THE WALLS AND THE FINISH FLOOR.

 

WHAT IS A "SPRINGY EFFECT" AND WHAT DISCOMFORT DOES IT CAUSE?

 

SHORT ANSWER: 

THE FEELING OF AN UNSTABLE FLOOR UNDER YOUR FEET, AS IF YOU ARE SAILING ON THE OCEAN.

 

EXTENDED ANSWER: 

A FEELING OF LIGHT DIZZINESS AND AN UNSTABLE FLOOR UNDERFOOT, AS IF YOU ARE SAILING ON THE OCEAN OR WALKING ALONG A TRAMPOLINE. 

YOUR BRAIN AND VESTIBULAR APPARATUS PERCEIVE THESE SIGNALS NEGATIVELY.  STEICO WOOD UNDERLAYMENT EVENS OUT SIGNIFICANT UNEVENNESS IN THE FLOOR AND CREATES A RIGID BASE, SIGNIFICANTLY EXTENDING THE LIFE OF THE FLOOR.

 

1.f. HIGH THERMAL RESISTANCE (8:09) 

 

WHAT HAPPENS TO SOME UNDERLAYMENTS WHEN THEY ARE EXPOSED TO HEAT?

 

SHORT ANSWER: 

THEY SHRINK IN SIZE.

 

EXTENDED ANSWER: 

SYNTHETIC POLYMER UNDERLAYMENT IS MADE FROM VARIOUS PLASTICS IN THE FORM OF FOAM THAT IS THEN INSTANTLY HARDENED DURING PRODUCTION SO THAT IT RETAINS ITS CELLULAR STRUCTURE. 

IT IS VERY LIGHT AND INEXPENSIVE SINCE IT IS 95-98% AIR. 

WHEN HEATED, THE STRUCTURE OF THE UNDERLAYMENT IS DESTROYED (MELTED), AIR ESCAPES, AND ITS DIMENSIONS CHANGE DRAMATICALLY.

 

WHAT EFFECT DOES A CHANGE IN THE SIZE OF THE UNDERLAYMENT HAVE?

 

SHORT ANSWER: 

ITS SOUND AND HEAT INSULATION PROPERTIES DISAPPEAR.

 

EXTENDED ANSWER: 

EVEN SMALL GAPS BETWEEN THE UNDERLAYMENT SHEETS GREATLY REDUCE ITS INSULATING EFFECT. 

NATURAL MATERIALS SUCH AS CORK, WOOD FIBER, WOOL, AND FELT PRACTICALLY DO NOT REACT TO HEATING, SINCE POROSITY, CAPILLARITY, AND FIBRILLATION ARE NATURAL PROPERTIES OF THOSE MATERIALS.

 

1.g. FIRE RESISTANCE (9:08)  

 

WHAT ARE THE BENEFITS OF BUILDING MATERIALS THAT POORLY SPREAD FIRE THROUGHOUT THEIR SURFACE?

 

SHORT ANSWER: 

THEY ALLOW FOR EXTRA TIME FOR FIREFIGHTING OR EVACUATION.

 

EXTENDED ANSWER: 

THE LESS TIME IT TAKES TO IGNITE A MATERIAL, THE FASTER THE FLAME WILL REACH THE BUILDING'S SUPPORTING STRUCTURES AND WEAKEN OR DESTROY THEM. 

THUS, THE USE OF MATERIALS THAT DO NOT SPREAD FIRE WELL SIGNIFICANTLY INCREASES THE CHANCES OF EXTINGUISHING THE FLAMES, REMOVING PEOPLE FROM THE BUILDING, AND PRESERVING THE STRUCTURES OF THE HOUSE.

 

WHY DO WOOD FIBER MATERIALS CAN RESIST AN OPEN FIRE FLAME FOR A PROLONGED PERIOD OF TIME? 

 

SHORT ANSWER: 

SUPERFICIAL CHARING INHIBITS THE SPREAD OF FIRE.

 

EXTENDED ANSWER: 

WOOD FIBER CHARS QUICKLY AND PREVENTS FIRE FROM SPREADING OVER THE SURFACE AND INTO THE INTERIOR. 

GLUED WOODEN BEAMS WITH LOAD-BEARING METAL STRUCTURES INSIDE ARE OFTEN USED TO PROTECT LARGE PUBLIC BUILDINGS FROM COLLAPSE IN CASE OF FIRE, SUCH AS WATER PARKS, CONCERT HALLS, SHOPPING CENTERS, AND SPORTS FACILITIES. 

WHEN WOOD IS CHARRED, IT PROTECTS STRUCTURES FROM DIRECT FIRE DAMAGE AND THE LOSS OF THEIR LOAD-BEARING PROPERTIES. 

AS SOLUTIONS GO, IT’S TECHNICALLY EFFICIENT, BEAUTIFUL, ENVIRONMENTALLY FRIENDLY, AND MODERN.

 

2. MODULE #2: INSTALLATION LIBRARY.

 

2.a. PREPARATION FOR INSTALLATION (10:49) 

 

WHY IS IT NECESSARY TO ALLOW ADAPTATION TIME FOR NATURAL MATERIALS? 

 

SHORT ANSWER: 

TO EQUALIZE THE MOISTURE AND TEMPERATURE OF ALL THE MATERIALS.

 

EXTENDED ANSWER: 

BUILDING MATERIALS DELIVERED TO THE SITE ARE STORED PRIOR TO PURCHASE IN A WIDE VARIETY OF CONDITIONS. 

MATERIAL THAT IS TOO DAMP CAN DRY OUT AFTER INSTALLATION AND CAUSE CRACKS AND FRACTURES. 

MATERIAL THAT IS TOO DRY CAN INCREASE IN SIZE AND CAUSE THE STRUCTURE TO SWELL. THEREFORE, IT IS ALWAYS ADVISABLE TO ALLOW TIME FOR MATERIALS TO ACCLIMATE.

 

HOW MUCH TIME IS REQUIRED FOR THE MATERIAL TO ADAPT?

 

ANSWER: 

AT LEAST 48 HOURS.

 

2.b. LEVELING OF FLOORS (11:50) 

 

WHAT IS A QUICK WAY TO RAISE THE LEVEL OF A SUBFLOOR?

 

SHORT ANSWER: 

LAY ONE OR MORE LAYERS OF HARD WOOD PANELS SUCH AS PLYWOOD OR STEICO WOOD UNDERLAYMENT ON THE SUBFLOOR.

 

EXTENDED ANSWER: 

THE ABILITY TO AVOID THE MANUFACTURE OF CEMENT SCREEDS GREATLY SPEEDS UP CONSTRUCTION AND REDUCES PROJECT COSTS. 

LAYING DOWN SEVERAL LAYERS OF STEICO WOOD UNDERLAYMENT IS THE FASTEST WAY TO RAISE THE LEVEL OF THE FLOOR, SIGNIFICANTLY IMPROVE THE SOUND AND THERMAL INSULATION OF THE BUILDING, SMOOTH OUT ANY UNEVENNESS IN THE SUBFLOOR, AND MOVE ON TO FINISHING THE FLOOR.

 

WHAT IS THE REASON THAT A FLOOR MADE OUT OF A FEW LAYERS OF STEICO WOOD UNDERLAYMENT DOES NOT BEND OR COLLAPSE?

 

SHORT ANSWER: 

STEICO WOOD UNDERLAYMENT CAN WITHSTAND VERTICAL PRESSURE UP TO 21,32 PSI; IT IS STRONG, HARD AND ELASTIC.

 

2.c. CONCRETE SUBFLOOR (13:14)  

 

WHAT IS THE BENEFIT OF THE UNDERLAYMENT IF THE SUBFLOOR IS UNEVEN?

 

SHORT ANSWER: 

IT WILL SMOOTH THEM OUT.

 

EXTENDED ANSWER: 

A THICKER UNDERLAYMENT WILL SMOOTH OUT RAISED IRREGULARITIES IN THE FLOOR AND ELIMINATE SMALL DEFECTS AS MUCH AS POSSIBLE.

 

WHAT IS THE MAXIMUM LEVEL OF INCLINE IN SUBFLOOR?

 

ANSWER: 

1/10” PER 6-7’ OF SUBFLOOR SURFACE.

 

2.d. DEFECTS AND BULGES IN THE SUBFLOOR (14:31) 

 

WHAT IS THE UNIQUE STEICO WOOD UNDERLAYMENT FEATURE FOR SMOOTHING OUT RAISED

IRREGULARITIES IN THE SUBFLOOR?

 

SHORT ANSWER: 

ABSORPTION OF UNEVENNESS.

 

EXTENDED ANSWER: 

STEICO WOOD UNDERLAYMENT DOES NOT MOLD TO THE UNEVENNESS, TRANSFERRING IT TO THE FINISH FLOOR, BUT ABSORBS IT INTO ITSELF, MUCH LIKE PLASTICINE OR DOUGH FALLING ONTO AN UNEVEN SURFACE. 

IT’S AN IMPORTANT FEATURE THAT ALLOWS YOU TO QUICKLY AND EFFICIENTLY PREPARE THE SUBFLOOR FOR INSTALLATION.

 

WHAT CAN BE DONE WHEN THE BULGES IN THE SUBFLOOR ARE QUITE LARGE?

 

SHORT ANSWER: 

SELECT AN UNDERLAYMENT THAT IS THICKER THAN THE IRREGULARITY IN THE FLOOR.

 

EXTENDED ANSWER: 

THERE ARE THREE ADDITIONAL WAYS TO SMOOTH OUT SIGNIFICANT IRREGULARITIES. 

YOU MUST CHOOSE AN UNDERLAYMENT THICKER THAN AN UNEVEN AREA OF THE FLOOR:

 

1. PLACE THE UNDERLAYMENT ON THE UNEVEN AREA AND TAP ON TOP OF IT WITH A RUBBER MALLET SO THAT THE UNDERLAYMENT IS PRESSED INTO IT.

 

1. CREATE A DEPRESSION IN THE UNDERLAYMENT WITH A UTILITY KNIFE FROM BELOW AND

USE IT TO COVER THE UNEVEN PART OF THE FLOOR.

 

1. PLACE THE UNDERLAYMENT ON THE UNEVENNESS, CUT A HOLE ALONG THE PERIMETER OF IT, AND FIT THE UNEVEN PART OF THE FLOOR THROUGH THE HOLE. 

KNEAD THE PIECE CUT OUT OF THE UNDERLAYMENT UNTIL IT REACHES THE CONSISTENCY OF A SOFT FIBER (LIKE COTTON WOOL OR OAKUM) AND LAY IT TIGHTLY OVER THE UNEVENNESS (BUMP). 

THE FINISH FLOOR WILL BE PLACED OVER THAT PIECE OF FIBER.

 

2.e. MOISTURE AND VAPOR BARRIER (16:00)

 

WHAT IS THE PURPOSE OF PLACING A HYDRO-INSULATION PLASTIC FILM UNDERNEATH THE UNDERLAYMENT?  

 

SHORT ANSWER: 

IT ELIMINATES DIRECT CONTACT WITH WATER AND PROTECTS FINISHING MATERIALS FROM DETERIORATION.

 

EXTENDED ANSWER: 

THERE ARE ALWAYS CONDITIONS OR SITUATIONS WHERE MOISTURE CAN ENTER THE ROOM AND CAUSE DESTRUCTION TO MATERIALS—FLOODING, LEAKS, RISING GROUNDWATER LEVELS, A BREACH OF THE EXTERNAL WATERPROOFING OF THE BUILDINGS, AND MORE. 

THE USE OF WATERPROOFING AND VAPOR BARRIER FILMS WILL PROTECT THE UNDERLAYMENT AND THE FLOOR FROM DESTRUCTION, AND THE ROOM FROM THE UNCONTROLLED SPREAD OF MOLD AND MILDEW. 

IN ANY CASE, THE SOURCE OF MOISTURE MUST BE REMOVED AS SOON AS POSSIBLE.

 

WHAT SHOULD BE THE THICKNESS OF THE PLASTIC FILM?

 

ANSWER: 

6 MIL.

 

2.f. “DEFORMATION PROTECTION” SPACE (17:19) 

 

WHY IS LEAVING A "DEFORMATIVE SPACE" NECESSARY? 

 

SHORT ANSWER: 

TO PREVENT THE FLOOR FROM WARPING WITH SEASONAL HUMIDITY INCREASES OR TEMPERATURE SPIKES.

 

EXTENDED ANSWER: 

TO PREVENT THE FLOOR FROM WARPING WITH SEASONAL HUMIDITY INCREASES OR TEMPERATURE SPIKES. 

USUALLY, IF SOUNDPROOFING OF THE PREMISES IS NEEDED, THE EXPANSION GAP IS FILLED WITH A SOFT, NON-HARDENING SEALANT (FOR EXAMPLE, SILICONE).

 

WHAT IS THE THICKNESS OF THE SPACE THAT SHOULD BE LEFT?

 

ANSWER: 

USUALLY 1/8” – 1/4”, BUT NO THICKER THAN 1/2.

 

2.g. SEAMS BETWEEN THE UNDERLAYMENT BOARDS (18:37)  

 

WHAT IS THE PURPOSE OF THE SCOTCH TAPE?

 

SHORT ANSWER: 

ONLY FOR CONVENIENCE ON THE JOB.

 

EXTENDED ANSWER: 

IT’S USED AS BACKUP ON THE JOB WHEN THE PREMISES MUST BE SOUNDPROOFED SO THAT SLABS STAY TIGHTLY PRESSED AGAINST EACH OTHER.

 

WHAT IS THE BEST SCOTCH TAPE TO USE?

 

ANSWER: 

ANY CONSTRUCTION TAPE.

 

2.h. CUTTING AND HANDLING THE UNDERLAYMENT DURING INSTALLATION (19:34)  

 

WHAT IS THE FASTEST METHOD OF CUTTING THE UNDERLAYMENT?

 

SHORT ANSWER: 

TRACING THE CUT LINE WITH ANY POINTED OBJECT AND THEN BREAKING ALONG THE LINE.

 

EXTENDED ANSWER: 

FIBROUS MATERIALS CAN BE CUT VERY QUICKLY WITH A SHARP KNIFE. 

BUT VERY OFTEN, THEY SIMPLY PULL OUT A SIGNIFICANT PORTION OF THE FIBERS WITH THEM. THEREFORE, NOTCHING IT, PULLING ALONG THE CUT LINE, AND THEN BREAKING IT IS A VERY SIMPLE AND QUICK WAY TO WORK WITH THE UNDERLAYMENT.

 

WHAT HANDY SHARP OBJECTS ARE BEST TO USE IN CUTTING THE UNDERLAYMENT?

 

ANSWER: 

NAILS, PENS, SCREWS, DULL KNIVES, ETC.

 

2.i. INSTALLATION OF THE LAMINATE FINISHED FLOOR (21:13)

 

WHAT IS THE BEST ADVICE FOR FLOOR INSTALLATION?

 

SHORT ANSWER: 

FOLLOW THE FLOOR MANUFACTURERS RECOMMENDATIONS.

 

2.j. INSTALLATION OF BASEBOARDS (22:04)

 

WHY IS IT RECOMMENDED TO LEAVE SPACE BETWEEN THE BASEBOARD AND THE FLOOR?

 

SHORT ANSWER: 

TO BREAK THE SOUND BRIDGE BETWEEN THE FLOOR AND THE WALL.

 

EXTENDED ANSWER: 

IF THERE ARE REQUIREMENTS FOR CREATING A CERTAIN LEVEL OF SOUND INSULATION IN A ROOM, THEN IT IS NECESSARY TO USE NOT ONLY THE APPROPRIATE MATERIALS BUT ALSO TO PROPERLY ASSEMBLE THE STRUCTURE. 

SOUND SPREADS THROUGH A BUILDING THROUGH MATERIALS THAT ARE NEAR EACH OTHER. 

IT’S NECESSARY TO CREATE ACOUSTIC GAPS SO THAT SOUND IS NOT TRANSMITTED FROM ONE SURFACE TO ANOTHER. 

IF YOU PRESS A GLASS AGAINST THE WALL WITH ITS BASE AGAINST YOUR EAR, YOU CAN HEAR WHAT’S HAPPENING IN THE NEXT ROOM. 

IF THE SMALLEST GAP APPEARS BETWEEN THE GLASS AND THE WALL, YOU WON’T BE ABLE TO HEAR ANYTHING.

 

WHY IS THERE NO SPACE LEFT BETWEEN THE FLOOR AND THE BASEBOARD IN THE VIDEO?

 

ANSWER: 

IT WASN’T NECESSARY TO SOUNDPROOF THE ROOM.
