Material sourcing guide

Insulation and waterproofing, defined by their application.

Thermal, acoustic, water, air and firestop materials solve different project requirements. Start with the application and assembly detail, then specify the product, accessories and documents suppliers should include.

01 / Products and uses

Identify the products you need.

Thermal and acoustic insulation

For envelope layers and partitions, name the intended application and designed performance. Distinguish boards, rolls and loose materials rather than comparing thickness alone.

Water and air control

For wet areas, roofs and below-ground zones, identify waterproofing and air/vapour-control layers using the project detail. Include joints, edges and penetrations in the request.

Passive firestopping

For service penetrations and joints, reference the specified assembly and opening conditions. Ask suppliers for evidence for the proposed system; avoid assuming any filler is suitable.

02 / Materials in the quotation

List materials, accessories and delivery terms together.

Your material schedule

02Water and air control
03Passive firestopping

List main materials and accessories as separate items. Use this checklist to prepare the information needed before requesting quotes.

Main materials

Describe each insulation or membrane layer by application, format and quantity, linked to the current project detail.

Complementary products and delivery details

List tapes, sealants, fixings, edge pieces and penetration accessories, and identify which supplier should include each item.

Ask what is excluded

Clarify substrate preparation, installation, inspection and waste allowances; do not infer a complete installed system from a material line.

03 / Before requesting quotes

Details to include in your request.

Application and substrate
State where the material is used and the adjoining surface so suppliers can identify compatibility limits.
Required performance
Use the project specification and request documents for the actual proposed product or assembly.
Thickness and format
List thickness, board or roll dimensions and net quantities without using thickness as the sole comparison.
Assembly detail
Attach the current assembly or penetration detail and identify where each product is used.
Joints and connections
Identify joints, terminations and service penetrations with the associated accessory list.
Packaging and storage
Request pack quantities, storage conditions and phased deliveries suitable for the site plan.

Example quantities only; no live prices or supplier offers. Use your project schedule for final values and ask suppliers to list deviations.

04 / Compare the whole offer

What to check when comparing quotations.

Same intended application

Compare the proposed use and required performance before looking at matching dimensions.

Product versus system

Check whether rolls or boards are quoted alone, or with the accessories needed by the specified assembly.

Documented compatibility

Request supplier evidence for products used together and a clear statement of deviations from the project detail.

05 / Practical questions

Frequently asked questions

Is matching thickness enough to compare offers?

No. Record application and required performance as well as thickness. Ask for the proposed product or assembly documents.

Do tapes and sealants belong in the insulation package?

List them explicitly. Ask the supplier to identify items included in the price, optional items and products to be purchased separately.
