GREEN LID Garden Rooms

Trade Supplier of SIPS Structures

GREEN LID utilise SIPS Panels (or Structural Insulated Panels) which are manufactured using facings of OSB (oriented stranded board) with a filling of PUR (polyurethane) insulation.

These structural panels provide a labour & material-saving alternative to the traditional timber frame or masonry construction.

The insulation used in our panels is continuous and is not bridged by timber studs. This type of panel has been in use for over 50 years and they offer an energy-efficient building system that substantially reduces on-site labour times & cost.

GARDEN ROOMS FAQ

What are the weights of each panel?

Our approx weights are:

  • 100mm – 48kg
  • 150mm – 52kg
What are SIPs panels made of?

SIPs (Structural Insulated Panels) are made using two facings of OSB3 (Oriented Strand Board) with a filling of PUR (polyurethane) insulation.

Are SIPs buildings sound proof?

They are better than timber frame (i.e. stud work). We have built recording studios using wood wall covering on top of our SIPs.

Are they fire resistant?

Our standard panels are not fire resistant, however you can clad them with plasterboard or CPB board to achieve a half hour fire resistance

What are the benefits of SIPs against timber framed builds?

Thermal performance, minimal Cold Bridging, minimal waste.

Do SIPs prevent Cold Bridging?

They are the most thermally efficient product at preventing Cold Bridging

What size building can be erected without planning permissions?

Up to 30 sqm2 internal area and under 2.5 metres if within 1 metre of the boundary and 4.5 meters if 2m away from the boundary

What can SIPs be used for?

Newbuilds, holiday homes, commercial property, classrooms, gyms, extensions, granny annexes, garden rooms, music studios – almost anything.

What bases can be used?

Studios – you can use the following bases: Concrete Base, Slabs, Helical Piles (Stop Digging) based on 1.5m centres.

Pads:

  • No more than 1.5m apart
  • 450mm square hole – dig out and fill with dry lean
  • You need a pad in each corner and either side of the door opening
  • Minimum of 50mm rebate or gap between the dirt (ground) and the studio
How long can I leave my uncompleted SIPs build open to the elements?

We recommend that the OSB is covered as soon as possible with some sort of water proofing on the roof & breathable membrane on the external walls. The OSB 3 is waterproof for a short period of time (approx. a month).

What lighting is best used in SIPs? Can I use sunked spotlights?

You cannot use sunken spotlights as the thermal efficiency of the panel will prevent the bulbs from cooling making them overheat and fail, should you wish to use sunken spotlights you need to batten down from the ceiling to provide an air gap.

What size battening do I use for my cladding and how far apart do I have to space them?

Battening is predominantly 25mm x 38mm (nominal) at 600mm centres, this must be on all corners and reveals regardless of the distance.
