Workshop insulation details. Includes attic and loft insulation guide along with wall and rafter instructions. Make a 50% difference immediately.
If you want to keep heat energy inside of your workshop, then you must insulate it. It is that simple. These procedures are specifically designed for pole barn type buildings, but are relevant to any structure.
Workshop Loft and Attic Insulation Guide
The process of heat transfer known as convection occurs as atoms speed up their movements as they become hotter. This means when they bump into each other they do it with a more force. The more force they bounce off each other with, the more the distance grows between them. In other words, matter expands as it heats up. This accounts for an increase in volume. This means that hot gases will be lighter than the same gas at a cooler temperature. It is no wonder that hot air rises.
If hot air is making its way up, then so is most of the heat. Overhead insulation will retain a much higher percentage of heat than insulated walls. Most workshops of any size are built with roof trusses. Typically they are spaced from 16″ – 24″ apart. High R value insulation is readily available for all the standard layout widths. This paper backed fiberglass insulation is easy to attach overhead with a small staple gun.
Stapling insulation overhead is only temporary. A professional job would involve covering the ceiling with drywall or even better, covering it with metal roofing. Metal roofing makes for an extremely effective and good looking ceiling in any workshop. Check out How to Install Metal Roof for installation details that apply to any application.
For barn lofts and bonus rooms over garages that need insulation, you must insulate between the rafters. This is accomplished by using the same batten type material mentioned before. 2 x 6 rafters are not hardly deep enough for 8″ insulation so they must be furred down with 2 x 2 strips in order to be effective. While metal roofing and drywall are certainly options for covering the rafters, we recommend using tongue and groove 1 x 6 pine. This will make for a simply beautiful ceiling in the attic. Just remember; if you are using a heat source such as a wood stove or a gas burning heater, then do not insulate between the floors. you will be blocking the heat from rising into the needed area.
Insulating the Walls of a Post and Beam Workshop
If you built your own workshop, then you are familiar with nailing on girts to the post and then installing siding. the interior of the wall should be handled the same way. Never leave exposed insulation. It is a health and safety hazard. Insulating a wall with 6 x 6 post and 1 1/2″ girts on each side will be as efficient of an insulated wall as there is. We recommend using either metal or tongue and groove wood for the interior of the wall.
The layout for Pro Barn Plans skips around a bit. We try to include a different construction technique with each project. Please read Workplace Safety Concerns before attempting any construction project.
At first glance, this may seem like extreme measures to take for insulating a wall. In fact, they are not extreme, they are minimum. Insulating your workshop with these procedures will make your building much easier to heat and much more sound proof.
