The DYER FIBERGLASS 'F' SERIES (aka: CUSTOM building) is a simple type of construction combining new materials with old, proven methods. This includes the use of wooden structural members; rigid sprayed and board polyurethane foams; and resins resistant both to chemicals and ultraviolet light. This combination offers enchancement to both the new and old usages of materials.

The DFI Custom Building process, unlike most of our competitors', begins with creating a skeletal framework from selected, dried wood; much like building the wall of a house. Any non-molded FRP building must have something (usually foam sheets) for the fiberglassed resin to 'lay' on. The core gives the fiberglass a "shape", and perhaps adds insulation properties. The fiberglass draws tight around the core and produces high tensile strengths at low weights, while adding its own insulation properties. The DFI advantage is the wood framework we use as our core; the framework allows us to seal a layer of insulating foam within every wall and ceiling panel we make. The framework also allows us to more efficiently design windows, doors and cutout plates into the panels: which means we don't charge extra for things like doors. The wood provides a cheaper, lighter framework than steel; and has better insulation values itself than either steel or aluminum. The use of wood also speeds our construction process. The fiberglass, meanwhile, lends its high tensile values and further insulation properties to the wall panel while thoroughly protecting the wood from infiltration by insects or dampness.

There are no 'standard' sizes or models for our Custom Buildings: that's why they're "Custom"! However, below is a list of various drawings and photographs from recent jobs we completed in the last few years. You may also click on a hyperlink which will take you to our general Guide Specifications.

If you want to talk pricing, give us a call and tell us how large a building you need and what you're planning to use it for. Remember that we will try to custom-fit the building to your application; it actually saves you money up front! (For example, it's better for you if we discuss a building that really only needs 49" x 57" x 63"H in its interior measurement than a 6' cube... by fitting it to what you really need, we save you some money.)

First, here are some cross-sections for various modifications to the general wall and roof structure which we've developed over the years. Some modifications increase the price (flange position and roof peak do _not_ involve price increases.) These are intended to be used as examples of ways we've customized the basic design. Combinations of characteristics not shown are quite possible.

CROSS-SECTIONS [Brackets give examples of usage.]
2-1/2" wall, interior flanges, no sound foam. [Most purchased type]
2-1/2" wall, outer flanges, no sound foam, flat roof. [Often used for short, long backflow preventers.]
2-1/2" wall, outer flanges, sound foam, peaked roof. [Standard sound enclosure.]
2-1/2" wall, 3/4" plywood reinforced. [This modification can be used for large wall attachments.]
4" wall, interior flanges, peaked roof, no sound foam. [Usually necessary for large buildings, or when extra insulation is required. Sound foam can be easily added if necessary.]

Next, here are some sample drawings from various jobs we've done in the past few years. Some drawings are quick sketches we made for quotes. Others are scale-drawings for submittals. All buildings represented were constructed and sold.
