Fabric Building Insulation Guide | Kits & Other Brands

Prepared by MAX Storage Buildings · Updated September 16, 2026 · Insulation supply only

Can you insulate a fabric building?

A fabric building can be considered for insulation when its frame, attachment arrangement and complete enclosure are suitable for the proposed use. The building brand alone does not answer that question. Review the actual structure and project requirements before ordering.

MAX DrySpan 6R20 is 6-inch, R-20 fibreglass insulation enclosed in vinyl, offered as a supply-only package. MAX accepts enquiries for its own buildings and other brands. Installation, building modifications and approval of the attachment design are outside the insulation supply offer.

Measure the envelope, not just the floor.

The envelope is the roof and walls surrounding the space. For an arched or peaked roof, the inside profile is longer than a straight line across the floor.

Send these details to MAX

Building brand, model and approximate year, if known
Width, length, peak height and sidewall or foundation-wall height

Whether you want the roof/sidewalls, end walls, or both
Your town/province or postal code for the supply quote

For initial planning, roof/sidewall area follows the measured interior profile × length. End walls are calculated separately, less the openings that will remain uninsulated. Final ordering must also account for the layout, joints, cuts and waste. Do not order from width × length alone.

Don’t have every measurement yet? Start with the dimensions you know.

Check the building as a whole.

Support and clearance

Confirm where insulation can be supported, the added loads and clearances around trusses, bracing, doors and equipment. Use the building manufacturer’s instructions and an appropriate project professional where needed. Do not improvise attachment points from a product photograph.

Heat loss, air leakage and moisture

R-value describes resistance to heat flow through the material. Gaps, compressed sections, framing and air leaks affect the finished assembly. Sealing panel joints alone does not address every door, penetration or ventilation requirement.

DrySpan sections can be joined and cut edges resealed with suitable vinyl seam tape. Ask for the correct tape specification and quantity in your quote. Confirm the moisture-control plan for your climate and use, especially for high-humidity activities.

Lighting, fire requirements and intended use

Adding opaque insulation under a light-transmitting roof changes daylight inside. Include lighting in your plan. Check the product documentation and any fire-performance or interior-finish requirements for your proposed use with the relevant authority or project professional.

For general insulation principles, see Natural Resources Canada’s insulation materials guide. That guidance does not certify DrySpan or approve a particular fabric-building retrofit.

Building kit, auction purchase or custom structure: request a MAX insulation-supply quote for the building you own. Start with your brand or seller below.

Keep your building’s identity in the quote. Two structures with the same floor dimensions may have different roof profiles, frame arrangements and support requirements. Every request is reviewed for the actual building.

Insulation enquiries for building kits and package sellers

TMG Industrial, Uncle Wiener’s, Suihe, Gold Mountain, Hills Industrial, Chery Industrial and the other names below identify buildings or sellers you may know. Choose yours to start a supply enquiry with the brand already filled in.

Have the kit details handy?

Include the model number from the crate, label, manual or order paperwork.
Tell us whether the building stands on the ground, a raised wall or shipping containers.
Note the roof shape, frame spacing and any existing liner. Photos or drawings help with the follow-up.

A seller’s name alone does not identify the frame or confirm it can support insulation. The actual model and attachment arrangement need to be reviewed.

Auction purchase or unknown brand?

You do not need to know the original manufacturer to start. Give us the approximate dimensions and any model number or name on the crate, manual or auction listing. We’ll follow up on the details needed for your supply quote.

Brand and seller names belong to their respective owners and identify buildings customers may own. MAX is not affiliated with these businesses. No universal fit, endorsement or manufacturer-approved retrofit is implied.

Price the complete supply scope.

Ask for a roof/sidewall package with end walls shown separately. Have the quote identify material quantity, tape and accessories, freight, taxes and availability. The insulation supply price is separate from the building kit and any installation labour.

MAX does not install insulation. Confirm your installer and the support method before committing to the material order.

Just dealing with condensation?

If your main concern is condensation dripping onto stored equipment, first look at ventilation, moisture sources and the separate 400g inner liner. It carries no R-value claim. DrySpan is the thermal-insulation product; describe the problem so the quote matches what you need.
