All Modular’s kits are built using Structural Insulated Panels (SIPs) from floor to ceiling.
With their high thermal values for year-round comfort, plus the ease with which the buildings can be pre-assembled and simply dropped into place on-site, they offer fantastic efficiencies.
The adaptability and speed of construction, the styling flexibility and high performance, combined with cost savings, means no other form of construction comes close.
We are continually adding new building designs to our range allowing you to offer more choice for your customers.

MATERIALS SUMMARY

SIP Panels
All our panels are meticulously manufactured from PU closed cell foam sandwiched between 2 OSB3 Sheets.

Joining Splines
Joining Splines are mini SIP pieces which join the main SIP panels together. This creates a constant insulation run which minimises cold bridging.

C24 Timber
Structural graded timber is used to form the base plate, to fix the SIPs to the base top plate which ties the SIPs together and the corners, giving a solid fix when joining in the corners and around window and door recesses.

Breathable Membrane
Breathable membrane is supplied to wrap your structure to keep moisture out whilst allowing the structure to breath. 2 x 1 battens are supplied to hold the membrane. (Please note, dependant on the type of cladding used more battens may be needed exclusive of the kit.

Fixing Pack
Includes a selection of screws, long structural anchor screws, low expanding adhesive for the joining splines and clear construction drawings for assembly.
