Dear Dave: If you are looking for an attractive, efficient sunroom, you probably don’t want a kit you build yourself. Most sunroom companies use factory-trained local contractors to build their sunrooms at homes. An efficient sunroom is a more complicated structure than you might realize.

There are some simple sunroom kits that use aluminum frames and clear plastic windows. They can be converted to a screened porch during summer by snapping out the self-storing plastic windows. They are functional and not terribly difficult to build, but they have somewhat of a “kit” appearance.

Another option is ready-to-install sunrooms that are delivered to your house already assembled. These are high-quality with beautiful solid-wood frames. Once the foundation and slab is ready, you can be enjoying the sunroom the same day it is delivered. They are one of the more expensive sunroom options, but you can finish the wood yourself to save some money.

You mentioned the south side of your house. This is a good location in cold climates if you want to use the sunroom during the winter without dramatically increasing your heating bills. In warm climates, or if you plan to use it as a three-season sunroom, an east or west orientation with deciduous trees for efficient shading may reduce summertime overheating.

The two key features to consider are the frame material and the type of glass. Aluminum frames, anodized or powder-coated, require the least maintenance and they are very strong. An aluminum frame should have a non-heat-conducting thermal break between the indoor and outdoor surfaces. This is more efficient and reduces wintertime sweating.

Wood frames are the most attractive and offer more decorative curved eave options. Wood is typically more expensive and requires periodic maintenance. If you like the appearance of wood, but not the hassles, select a combination wood-aluminum frame. The exterior surface is aluminum, but the interior is stained natural or painted wood.

Select double-pane glass with a low-e coating and argon gas in the gap. This will be efficient year-round and the low-e coating will block more of the ultraviolet rays. This will reduce fading and deterioration of carpets and furniture and your plants will thrive better with less UV.

Include some type of movable shading and ventilation methods. Intelligent venting skylights and inlet vents are available which open at a preset temperature and close if it rains.
