Holiday Home in druxberge “HOLIDAY HOME IN DRUXBERGE” FROM THE JANUARY/FEBRUARY 2016 ISSUE OF DETAIL REFURBISHMENT MAGAZINE GIVES THE READER A VIEW INSIDE A REFURBISHED, TWO STORY VACATION HOME IN DRUXBERGE, GERMANY, A SMALL VILLAGE WITH A POPULATION OF 408. WHEN THE SHUTTERS ARE CLOSED, THE BRICK BUILDING STEPS BACK TO 1930, APPEARING AS THE BARN STALL AND HAYLOFT IT ONCE WAS. WHEN THE WOODEN SHUTTERS ARE OPEN, A TRANSFORMATION TAKES PLACE. THE REFURBISHMENT HAS INCLUDED THE ADDITION OF DOUBLE GLAZED WINDOWS, THE

1

CONVERSION OF WHAT WAS ONCE PASSAGEWAYS INTO GLAZED DOORS AND MOST IMPORTANTLY THE ADDITION OF INSULATION.

INSULATION PROVIDES THE HIGHEST LEVEL OF……ENER-

FLACHSHAUS

AND

(STRAUBE, UENO, SCHUMACHER, 2011) FALKENHAGEN, THE CONTRACTORS INVOLVED IN THIS

PROJECT FELT THAT ADDING INSULATION TO THE INTERIOR WALLS AND CEILING SPACES PRESERVED THE HISTORICAL EXTERIOR AND MET THE NEEDS OF A HOME THAT IS ONLY USED FOR SHORT STAYS.

INTERIOR BY

INSULATION WOULD ALLOW THE STRUCTURE TO HEAT UP QUICKLY.

RETROFITTING, THE ORIGINAL TIMBER ROOF FRAMEWORK WAS PRESERVED AND SPACE CREATED BETWEEN THE RAFTERS FOR

THESE INSULATION ADDITIONS PROVIDE ADEQUATE COLD CLIMATE

INSULATION.

FLAX

INSULATION IS A SUSTAINABLE BUILDING CHOICE AS IT

HAS ENVIRONMENTAL, HEALTH, PHYSICAL AND APPLICATION ADVANTAGES.

AS

FLAX IS A NATURAL FIBER, IT HAS NO

EMISSION OF HARMFUL CHEMICALS, IS IT BIODEGRADABLE, REGROWS AND THEREFORE DURING ITS GROWTH, CONVERTS CARBON DIOXIDE INTO OXYGEN.

FLAX

INSULATION IS IN

ROLL FORM AND THEREFORE REDUCES THE AMOUNT OF SEAMS WHICH IS A POINT OF HEAT LOSS.

OLDER

BUILDINGS

TEND TO HAVE INCONSISTENT JOIST WIDTHS AND THEREFORE A ROLLED FORMAT OF INSULATION ALLOWS FOR QUICKER INSTALLATION. FOR

PPE

BEING

A NATURAL FIBER, THERE IS NO NEED

OR VENTILATION DURING INSTALLATION.

INSULATION HAS AN ESTIMATED SERVICE LIFE OF

SOFTBOARD

ONCE

FLAX

YEARS.

THERMAL INSULATION IS A GOOD ECO CHOICE

FOR THE WALLS OF NON-TOXIC

75

AND

HOLIDAY HOME

NON-IRRITATING

IN

DRUXBERGE

FOR

THE

INSTALLED, IT HAS ZERO EMISSIONS.

AS IT IS

INSTALLERS.

SOFTBOARD

IS

BOTH THERMAL INSULATION AND REDUCES NOISE TRANSFER FROM ROOM TO ROOM.

SOFTBOARD

IS LIGHT WEIGHT WHICH

IS SIGNIFICANT BECAUSE THE ORIGINAL

STRUCTURE

MAY NOT HAVE THE STRUCTURAL ABILITY TO WITHSTAND

THERMAL

INSULATION

IS

THE

A

TRAVERTINE,

GOOD

THERMAL

SUBSTANTIAL WEIGHT. CEMENT CHOICE

BECAUSE OF ITS ABILITY TO ACT AS VAPOUR BARRIER AND AIR BARRIER, ITS

R

VALUE OF

AND ITS ABILITY TO REDUCE THERMAL BRIDGING;

HOWEVER ENVIRONMENTALLY, CORK INSULATION PANELS OR SEMI-RIGID MINERAL

WOOL

PANELS

WOULD

HAVE

BEEN

A

BETTER

SUSTAINABLE

CHOICE.

CORK AND MINERAL WOOL ARE NOT MADE FROM PLASTIC OR PETROLEUM. XPS IS MANUFACTURED USING THE BLOWING AGENT HYDROFLUOROCARBONS (HFCS) THAT ARE HARMFUL TO THE ENVIRONMENT AND CONTRIBUTE TO GLOBAL WARMING. ALTHOUGH EUROPEAN MANUFACTURERS ARE CONVERTING TO NON-OZONE DEPLETING AGENTS, TOTAL ELIMINATION FROM XPS ISN’T SCHEDULED UNTIL 2020. THE

UPGRADES WE ARE PLANNING TO MAKE ON THIS WALL IS TO INCLUDE

THE APPLICATION OF A DRIP EDGE TO STOP WINDBLOWN RAIN FROM PENETRATING UNDER THE SHINGLES.

ALSO

WE WILL ADD WEEP HOLES TO THE

EXISTING BRICK WALL ALLOWING MOISTURE TO BE EXHAUSTED FROM WITHIN THE WALL.

MORE

FLASHING WILL BE ADDED TO TAKE WATER AWAY

FROM THE BUILDING ENVELOPE.
