Humidity and Temperature Measurements

Temperature and humidity measurements were made in the orawl spaoe, living area, attio spaoe and outdoors.

These observations are tabulated below:

On 1 May 1961 a third visit was made to the Mark I Researoh House near Preston, Ontario. The observations made during the first visit in February 1958 and a desoription of the house are reported in Visit Report No. 38 of the Division of BUilding Researoh; observations made during the seoond

visit in November, 1958 were desoribed in Teohnical Note No. 298. During the third visit, the writer was aooompanied by ltU". H. B. Diokens' of the DBR and Mr. G. Hipel, builder of the house.

-Crawl Space

The crawl space appeared to be very dry. The

perimeter insulation was dry to the touch and no evidence of condensation could be found anywhere, even beneath the

polyethylene vapour barrier. The floor joists revealed no sign of dry rot having occurred. The moisture content of the floor joists measured Ｖｾ per cent which indicates that the prevailing relative humidity in the crawl space prior to this inspection was comparatively low.

Attic Space

Some stains were noted on the paper-backed ceiling insulation indicating areas where water had dripped. The insulation beneath these stains was dry, however, and it is probable that these stains were the same ones that were observed during the first visit in February of 1958.

The framing members in the attic space had a moisture content of about 9 per cent, indicating that the prevailing relative humidity in the attic space prior to the third visit was slightly higher than in the crawl space. Living Area

The plaster cracks over the doorways in several of the rooms appeared to be about the same as observed during the November 1958 visit. Some new cracks had appeared at right angles to the ceiling joists in the living room,

however, parallel to the crack reported during the November

1958 visit.

In addition to these cracks, a number of hairline cracks were also observed in the living room ceiling parallel to the joists. The ceiling crack that had been patched prior to the November 1958 visit had moved slightly, showing a

hairline crack in the patched area. Mr. Ripel reported that the original crack had been caused in part at least by a ceiling joist which had twisted in place. No water stains were noted on the interior finish which would indicate any water leakage from ice damming or rain leakage.

The plaster beneath the living room window showed signs of water staining, presumably due to condensation running down from the Window, and had to be repainted. The home owner reported that condensation in the winter was so bad that a polyethylene storm window had been installed over the single glazing in the living room to attempt to control it.

-The painted plywood floor in the living room and hall had been covered with tile since the previous visit. It is understood that the tile was laid before the house was

occupied. The condition of the painted plywood in the

bed-rooms was about the same as during the previous visit.

Exterior Finish

The exterior siding had been given one coat of

grey paint in the spring of 1960. It was reported by the

home owner that the previous brown coat was in fairly good

condition at that time and the repainting was done mainly

for appearance. It was noted, however, that the plywood siding

on the south side of the house (rear) showed a considerable amount of checking which was not apparent during the previous

visit. This was the only side on which checking was extensive

(Pig. 1). Roof Covering

The asphalt shingles showed little if any change

in appearance from the previous visit. The home owner

con-firmed that no leakage in the roof had occurred either from ice damming or from rain.

General

The owner reported that she was generally pleased

with the house, except for the lack of storage space. She

indicated satisfaction with the heating system and reported that maintenance of comfort conditions was assisted in summer by the use of the furnace fan to circulate air from the crawl

space through the house.
