Finally the effects of interstitial condensation and good construction practice is covered.

The main theoretical problem in timber frame construction is interstitial condensation.

A vapour barrier may be necessary on the inner wall to prevent interstitial condensation.

Suitable consideration has to be given to ventilation passages to avoid interstitial condensation.

The moisture in the air condenses on cold surfaces, sometimes inside the walls called interstitial condensation.

It can be said to breathe in terms of moisture and offers reduced risk of interstitial condensation.

Analysis of infrared images can be useful in identifying moisture issues from water intrusion, or interstitial condensation.

The second problem is interstitial condensation.

Out of academic interest we ran a number of calculations to establish the conditions that would be required for interstitial condensation to occur.

Protection against interstitial condensation is necessary in heated or cooled buildings depending on the climate where they are located and other factors.

Incidentally, cavity wall insulation should be impermeable to water vapour, or interstitial condensation can occur.

At this position it is known as interstitial condensation, and will saturate the insulation, rendering it less effective.

Weeps may also be found in metal windows and glazed curtain walls to permit interstitial condensation to escape.

The main risk is of interstitial condensation, where warm moist air from inside the building condenses out on the "cold" side of the insulation.

It also addresses the significant problem of interstitial condensation which can cause a dramatic deterioration in the performance and probity of most building materials.

Air leakage, a very prominent mechanism operating in most buildings, transports water vapour into walls and roofs, producing interstitial condensation.

However, we monitor all reports of building failures in Britain and we have come across no evidence of interstitial condensation causing structural rot in practice.

The components of the wall are selected with the correct va-pour resistance to allow vapour to diffuse through the structure without the risk of interstitial condensation.

Because the insulating characteristics of timber-frame houses are so good they do give rise to the problem known as 'interstitial condensation', as was revealed in the television documentary.

The increase in interstitial condensation problems relate to the modern prevalence of central heating and air conditioning, the construction of air-tight, heavily insulated buildings with indoor plumbing.

The design complies with BS 5250: 1989 'Control of Condensation in Buildings' with no occurrence of surface or interstitial condensation.

Interstitial condensation is a form of structural damping that occurs when warm, moist air penetrates inside a wall, roof or floor structure, reaches the dew point and condenses into liquid water.

Where insulation is poor, the solution is to add extra insulation material - again, in conjunction with vapour barriers where appropriate, to prevent interstitial condensation from occurring within the house structure.

Failure to eliminate thermal pathways from warm to cold surfaces ("bridges") creates the conditions for interstitial condensation forming deep within the construction and lead to potentially serious issues of mould growth and rot.

Care should be exercised when adding a vapor barrier as it can reduce drying of incidental moisture, or even cause summer (in climates with humid summers) interstitial condensation and consequent mold and mildew.
