THERMAL AND MOISTURE PROTECTION


INTRODUCTION

The concept of thermal and moisture protection is to

guard against the unnecessary gain or loss of heat, and te-

guard against the unnzcc3s-ary intrusion of water. ;p this

study/the issues of thermal and moisture protection of

Floyd Hall arC-g ong- a- - amined.-- he-. ar t - be ad-

dressed in the following order: What -ws-the original mate-

rial was, wha-b the condition of that material -'4-~day, and

how would that material be repaired or replaced today-4i-



Floyd Hall is listed on the National Register of

Historic places. This listing requires that any exterior

work that is-dp 4 n.on the beuiding must not alter its char-

acter. As conscientious preservation architects, the buil-

ding must be restored following the Secretary of The Inter-

ior Standards for Rehabilitation. The areas which will be

looked at in this report are) the walls ' and the roof.

The walls of a building are major areas where heat leee-and

heat-gq;an. Their general construction, and windows and

doors are potential places for heat-loss or -gain. The roof

of the building protects the structure from harsh exposure

to the elements Tt- il.o provides thermal protection for

the building. he-iouf iS LjoTFcodcernH �i ormULLru OrT--

THE WALLS.

Thermal considerations. The wall construction of

Floyd Hall, through visual investigation, appears to be a

brick cavity wall Shi3 ccn truotioa needs to be verified

through selective demolition. Selective demolition should

oc0ur early in the design/construction phase to document

te wall materials and their condition. Heat transfer cal-

culations maybe Sane"to determine actual heat-loss or heat-

gain from the wall. As- an^ obrervat-ror when the building

was visited during the months of January and Feburary, the

inside temperature was relatively high. This may indicate

that the walls are providing enough thermal protection; if

this is the case, 4he construction should be documented and

left in its existing condition.

Doors and windows are another source of heat-loss or

-gain through a wall. These will be addressed in their re-

spective reports. General comments relating to thermal and

moisture protection of doors and windows are as follows:

Doors and windows should be repaired and properly insulated.

Care should be taken to insure that doors and windows.are

not sources of water intrusion. If water intrusion is peF-

Sae, this'must be corrected.

Moisture considerations. Moisture intrusion in a

brick wall generally comes from three places: rising damp,

the wall surface, or behind the surface in the case of a

parapet being present. In Floyd Hall these issues must be

investigated. Surface investigation did not show the






evidence of rising damp, (his should be furthered in-eli-

gate& through selective demolition. Water penetration
the surface of the brick and from behind at the parapet are

both problems peeent in Floyd Hall. Water penetration on

surface brick appears to be occ during in the gable/end walls-

ThiR may-be a result of water penetration from behind the

parapet. If investigation and selective demolition de er-

mine this is the case, flashing between the roof and the

parapet will need to be modified or replaced. Water pene-

tration also is present at other points on the wall surface.

These areas seem to be related to leaking or deteriorated

gutters. The gutters need to be repaired or replaced to

halt the excess water becoming present on the brick face of

the wall. Repointing may be necessary in certain areas where

water intrusi P has occoured. If repe~i- g is necessary,

rte should be done great care to insure visual apperance',-

and provide moisture protection.

THE ROOF

Thermal considerations. The roof of Floyd Hall is

presently in a great state of disrepairA T4 ji in neXe

rm teni.Lien"i~weoof. Sheathing, insulation, felts, and roof

tiles w44-A-all be replaced. At the time of al- aci ~fhi s,

4h- existing conditions of roof insulation should be docu-

mented. A new type of rigid insulation may be used for

roof insulation Whi s-wour4-be placed between the sheathing

and the tiles, provisions for -te members which supper the

roof tile would have to be considered in e rigid insulation.

The use of this rigid insulation would ease allow the inside AiGO

of the roof structure to be exposed if this is desirable.

Moisture protection. The roof is the single most im-
portant element of moisture protection in the building. -As.

tirely replaced. The roof should then be insulated and Nte-

roof tiles installed. The use of existing roof tiles is

possible.>As a part o+the roof investigation(the quality
of the roof tiles should be determined' This will gie an

of roof replacement, the flashing and gutters need to be

repaired or replaced. Thi h-bn- ioneS-as.pa. of

CONCLUSION
Thermal and moisture protection are important to the
successful use of a space. Floyd Hall presently has a few
problems with thermal protection, and some large problems
with moisture protection. The moisture protection problems
must be corrected. Re-roofing and Re-flashing the building
is most important and should be done if full ranovatign. takes
plaee or not.
