Our external walls are made up with 140mm x 38mm treated CLS Timber (High Quality timber imported from Sweden) We can also use a 184mm x 38mm Timber Stud if a very low U-Value if required.
A 9mm OSB 3 fitted on the exterior of the studs. Followed by breather membrane.
We also provide structural steel as specified by a structural engineer. All of our kits come with the necessary fixings for on-site assembly. We also supply external stainless-steel hold down straps, stainless steel wall ties, wall vents & fire prevention bags.
Each wall panel is made in a factory environment to ensure maximum quality and are fitted together on site.
Internal walls are made up of 89mm x 8mm CLS Timber and if the wall is load bearing it will be sheeted with 9mm OSB 3 Board.
Smart-ply OSB 3
Smart-ply OSB 3 is a highly engineered, moisture resistant, load bearing panel which is designed for use in many structural and non-structural applications in both internal and external environments. Manufactured in accordance with EN 300 performance standard. It is perfect choice for sheathing, roofing, flooring and many other applications where strength and moisture resistance are paramount.
When there is a requirement for steel, ex. large spans above openings, corner windows, portal frames for a vaulted ceiling or just for racking purposes because of a house location – near the sea for example.
All steel is designed by a structural engineer and manufactured to the highest standards
External Breather Membrane
External breather membrane is a single layer, vapour permeable membrane for use on Timber Frame walls.
Reflective External Breather Membrane
Reflective external breather membrane is a strong, water-resistant breather membrane with a metallised surface that helps to improve thermal efficiency by reflecting radiant heat in summer and reducing convective heat loss in winter.
Stainless Steel Hold Down Straps
Stainless steel hold down straps fitted at centres shown in the structural calculations
Stainless Steel Wall Ties
Stainless steel wall ties for connecting the timber frame to external block / brick work.
Cavity barriers – TCB Cavity Barrier and PWCB Cavity Barrier – have been developed to exceed minimum building regulation requirements for fire resistance with concealed wall cavities. Tested and assembled to BBS476: Part 20, they provide p to 60 minutes fire resistance (integrity and insulation).
Drill Vent – Cavity Venting System
DrillVent is a new patented cavity venting system that not only solves the problems associated with the use of weep vents for cavity venting in Timber Framed Buildings but gives the added assurance that the cavity is suitably ventilated and drained.
DrillVent is retrospectively installed during the completion stage of the external wall.
Concerns associated with the use of traditional weep vents for venting cavities are eliminated, ie. inadequate venting and insufficient drainage.
With DrillVent, you are confident that the cavity is correctly ventilated and drained.
The slatted louvers are specifically designed to baffle direct blown wind. They are angled and spaced to promote the drying of condensation and rain-saturated outer leaf brick work whilst preventing the ingress of large insects.
DrillVent is an ideal solution for the retro-fitting of vents that have simply been left out, become damaged or blocked during the construction process.The circular design allows for efficient ventilation and is quick and easy to install. It has been engineered to be UV stable to ensure a long life.
DrillVent is available in three standard colours; transparent, beige and terracotta, complimenting popular external brick and modern rendered finishes.
DrillVent has been tested according to the principles of CEN standard EN13141-1: Ventilation for buildings – performance testing of components / products for residential ventilation.
