A Craft-Bilt thermal sunroom is a room specifically engineered to help control the interior environment of your sunroom for maximum comfort during the seasons of use.

The “thermal” protection is primarily provided by the type and amount of insulation within the wall and roof systems, working together with high-quality window systems and other engineering.

Craft-Bilt uses industry-leading 2-lb high-density Expanded Polystyrene, recognized as the most effective and durable insulation material in sunrooms. A Craft-Bilt  thermal sunroom also means that you can use it longer through the seasons.

The options in wall systems are designed to help you select the room that meets your expectations for use and geographical requirements, without paying for more than you require. Craft-Bilt  sunrooms are designed to provide 3-season use, or extended-season use.

 

3-Season Rooms

Our standard room provides superior insulation in the walls for strength and resistance against cold, but does not contain additional structural engineering to include a thermal break.

A thermal break is an additional barrier engineered into the wall that helps stop the transfer of outside cold from penetrating through the walls and into the room, providing maximum possible protection from the coldest weather.

Non-permanent supplemental heating or cooling can provide additional climate control. All supplemental heating should be electric-based, as in electric baseboard heat, or electric simulated fireplaces.

All fossil fuel burning systems (such as wood-burning heat generators) add moisture to the air, which can produce condensation on windows. Condensation naturally occurs when moist indoor air touches window glass that has been cooled by cold outdoor temperatures.

All Craft-Bilt  rooms utilize an exclusive thermal roof that contributes additional insulation performance, and overall structural strength.

 

Extended-Season Rooms

An extended-season room provides use throughout all seasons of the year, but does not mean that non-permanent supplemental heating or cooling may not be necessary.

An extended-season sunroom means that all elements of the room work together to hold out colder temperatures through more days throughout the entire year and keep the room comfortable longer.

These elements include the thermal roof, high-performance window systems and wall system, with its insulation and thermal break, and thermal break in the base channel.

With an extended-season room, the warmth of a sunny winter day may provide all the heat that is necessary for daytime enjoyment.

However, non-permanent supplemental heat may be required to make the room comfortable during the evening, or on a particularly cold and cloudy winter day. All supplemental heating should be electric-based, as in electric baseboard heat, or electric simulated fireplaces.

All wood-burning heat generators add moisture to the air, which can produce condensation on windows. Condensation naturally occurs when moist indoor air touches window glass cooled by outdoor temperatures.

The maximum insulation properties of the window systems used in our double-pane HPG 2000 glass and our Millennium windows contribute to the extended seasonal use of the sunroom.

The Millennium window is Craft-Bilt ’s highest-performance window system, providing maximum-duty protection against heat/cold transfer and solar UV penetration.

It is a thermally broken, double-pane insulated window unit that provides superior resistance against cold transferring from the outside to the room’s interior. In addition, it is designed to keep winter’s desirable warmth inside the room.

All Craft-Bilt  rooms utilize an exclusive thermal roof that contributes additional insulation performance, and overall structural strength.
