If these substrate panels are installed too close to each other they could push into each other as they expand from the heat resulting in buckling.
Roof substrate definition.
A substrate is the surface upon which a roofing system is applied.
The exposed portion of strip shingles defined by cutouts.
There are a variety of steel substrates and coatings available in the marketplace and the wrong selection could result in disappointment and reduced service life.
It can be the roof deck an insulation system or a complete preexisting roof system.
The primary function of a deck is to act as a unifying structural diaphragm by tying all the components of a roof together.
The sizes and proportions of small particles and their packing inside the large pores make a major contribution to the amount of water the mix can retain.
Fasteners and clips would be attached into the substructure.
What causes roof substrate movement.
Roof substrates otherwise known as roof decking or rigid sarking support other roof elements such as vapour control layers insulation and roof finishes.
Deck substrate a roof deck is a roofing material layer installed on top of the rafters and right under the insulating layers of underlayment.
Choice roof contractors select particular conklin roofing systems for roof repairs and restoration projects depending on the substrate that currently exists on the commercial roof.
The substrate or decking material typically plywood or oriented strand board osb expand and contract when exposed to heat resulting in roof substrate movement.
It often is used in part to support vapor retarders and air barriers.
An intentional depression around a roof drain or scupper that serves to promote drainage.
Roof substrate movement is a condition where the substrate or roof deck in residential properties expands and contracts.
In construction a roof deck is also known as sheathing or substrate.
Green roof growing substrates are designed to have a mix of large and medium sized particles to create an open porous structure inside which smaller particles can fit.
As a key part of the metal roofing system the substrate or substructure which rests underneath the metal roof panels serves two main functions.
There are many different types available including options for green roofs and fsc sustainably sourced and produced types.
In this blog we look at the causes of roof substrate movement.
It acts as a base to which the metal roof material is attached securing the fasteners and clips used to hold the panel.
When shopping for metal roofing purchasers must be vigilant to ensure the substrate and coating on the metal panels they choose will match their long term performance expectations.
