Part 1 - General

DESCRIPTION OF WORK:

Customized for each project

QUALITY ASSURANCE:

Manufacturer: Provide enclosure, including installation by a single firm, which has successfully specialized in production of this type of work for not less than 10 years.

Standard of quality is based on products of the company listed below. Provide pool enclosure by a manufacturer whose products comply with requirements established in the Contract Documents:

OpenAire, Inc.
2360-B Cornwall Road
Oakville, Ontario L6J 7T9

DESIGN:

Have work of this section designed by a professional engineer licensed to design structures. Comply with the requirements of the local building codes as applicable.

Thermal

Thermally break frame members. Provide thermal breaks between exterior and interior structural components to diminish the possibility of condensation forming on the interior metal surfaces.

Water & Moisture

Comply with design and performance requirements specified in the building codes and as specified below and design and engineer the work accordingly. In designing and engineering the work, the following principles shall be followed:

1. Make provisions to drain the exterior face of assembly any water entering at joints and any condensation occurring within the framing.
2. At design conditions no water penetration to the interior side of the assembly shall occur.
3. Design, fabricate and install the assembly to be watertight to the interior subject to the interior and exterior design conditions in combination with movements occurring due to loads imposed.

Air

Air leakage through the curtain wall shall not exceed 0.06 cfm per square foot of fixed wall area plus the permissible allowance specified for sliding doors and operating skylight panels within the test area when tested in accordance with ASTM E 283 at a static air pressure difference of 1.57 psf.

Vapor Barrier

The definition of the air/vapor barrier for the purpose of these specifications is "a continuous membrane including joints of membrane to adjacent construction which retards or prevents the rate of penetration of moisture laden air and the diffusion of water vapor through it".

Rain Screen

Base the design of the work of this section on the "rain screen" principle. Design and reinforce rigid air/vapor barriers to withstand acceptable deflection limitations, their own weight, the insulation weight and design loads.

All voids between the assembly components as well as between the components and the structure shall have:

1. Gaskets, baffles, overlaps and seals as required to provide a barrier "rain screen" to effectively prevent excessive rain water entry into any of the cavities but allow pressure equalization.
2. Non-permeable air seals as required to exclude the entry of interior building air into the skin cavities.
3. Such provisions in the form of openings between cavities and the building exterior of sufficient cross section to provide adequate pressure equalization. In addition, all openings shall be baffled against direct water entry.
4. Air seals placed to eliminate any contact between interior humid air and a cold surface or structural component to prevent condensation and ice build up on such surfaces during cold weather.
