A proper air conditioning system provides thermal comfort, acceptable indoor air quality, reduce air infiltration, control humidity and maintains good air distribution and air quality. The aim is to provide a suitable indoor environment that remains relatively constant despite changes in external weather conditions or internal heat loads.

Ventilation replaces air in any space to control temperature or remove moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and to replenish oxygen. Ventilation includes both the exchange of air to the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality. Kitchens, bathrooms and laundry rooms typically have some sort of ventilation to control odors, cooking vapors and sometimes humidity.



A quality metal roof will likely be the last roof you will ever need. Metal roofs are lightweight, fire resistant and durable. They provide energy savings, beauty, and protection for your property. Metal roofs can be used on residential, commercial, industrial or agricultural buildings. They are often used to cover large buildings because of their high strength to weight ratio and can be installed over an existing roof, eliminating the cost and ecoimpact of tear-off and disposal.

Offered in a variety of colors, the metal roofing can be either a seamless interlocking or a seamed system. Metal roofing is not damaged by mold and mildew and require very little or no maintenance. The materials used in metal roofing are available in aluminum, copper and zincalume. The same material used for metal roofs can be used equally well in cladding the sides of a buildings.



A gutter and downspout system is essential in protecting the foundation, walls and surrounding landscaping from water runoff which can cause a great deal of damage if it is not properly transferred away. Existing gutters which are neglected can lead to clogging, overflow, rusting or other damage that makes them less effective. Selecting a right gutter system requires a balance of practicality and aesthetics.

Gutters and downspouts are available in aluminum, galvanized steel, zincalume, stainless steel and copper. Gutters are either sectional or seamless and are available in various profiles ranging from rectangular, half-round and “K” profiles. Downspouts are available in round or rectangular shapes.

The roof is one of the most important yet vulnerable parts of a structure. One of the main reasons for wind related roofing failures has been improperly designed and installed metal roof edges. ANSI/SPRI ES-1 Wind Design Standard for Edge Systems Used with Low Slope Roof Systems (ES-1) standard was developed to address these concerns and improve the performance and longevity of roofs.

The 2003 version of the International Building Code requires that the roof edges be ANSI/SPRI ES-1 tested to ensure the roof edges have sufficient wind resistance against wind loads for long-term performance. 2003 IBC 1504.5: "Edge securement for lowslope roofs. Low-slope membrane roof systems metal edge securement, except gutters, installed in accordance with Section 1507, shall be designed in accordance with ANSI/SPRI ES-1, except the basic wind speed shall be determined from Figure 1609." All tests were conducted in accordance with the ANSI/SPRI ES-1 Test Protocols. Click here for Frequently Asked Questions.

Trash chutes are the centralized handling of general household or office waste for any mid-rise and high-rise building.

Chutes are typically constructed of 16 gage metal such as aluminum, galvanized or stainless steel.  Most trash chutes are generally from 20" to 36" in diameter.  Trash chute main components included the chute, vent top, intake and discharge doors.  Chutes are often times subjected to abuse when prohibited items are thrown in resulting in damage to the chute and/or the discharge section.  Repairs can be made to sections of the chute extending the lifespan and delaying the expensive cost to replace the chute.
